In these embodiments, the housing <NUM> is a main housing of the notebook computer. The first case <NUM> is a C member configured to mount an input device I. The second case <NUM> is a D member supported on a use surface. In this embodiment, the input device I is disposed on the upper surface <NUM> of the first case <NUM> and covers the through hole <NUM>. A space is formed between the second case <NUM>, the lower surface <NUM> of the first case <NUM>, and the side wall <NUM> for accommodating the first heat source <NUM>, the second heat source <NUM>, and the heat dissipation module <NUM>.

Refer to <FIG>. <FIG> is a schematic diagram of an embodiment of an electronic device with the second case <NUM> omitted and drawn from a viewing angle perpendicular to the lower surface <NUM> of the first case <NUM> according to the present invention. <FIG> is a schematic perspective view of a circuit board <NUM> with the second heat source <NUM> and the second heat conduction member <NUM> further omitted based on <FIG>.

In some embodiments, the first case <NUM> includes two partition walls <NUM> and a plurality of air flow channels <NUM>. The air flow channels <NUM> are provided passing through the side wall <NUM>. In these embodiments, each partition wall <NUM> is disposed on the lower surface <NUM>, and extends from the lower surface <NUM> in a direction away from the upper surface <NUM>. In this embodiment, two ends of each partition wall <NUM> are joined to the side wall <NUM>.

The first heat source <NUM> and the second heat source <NUM> can be disposed in the waterproof area B, to ensure smooth air flow of heat dissipation of the first fan <NUM> and the second fan <NUM>, thereby ensuring a heat dissipation effect and also ensuring the waterproofness of the first heat source <NUM> and the second heat source <NUM> that are located in the housing <NUM>, to avoid affecting the operation of the first heat source <NUM> and the second heat source <NUM>.

Referring to <FIG>, in this embodiment, the first case <NUM> further includes a penetrating hole <NUM> and a groove <NUM>. The penetrating hole <NUM> runs through the upper surface <NUM> and the lower surface <NUM> and is in communication with the non-waterproof area A provided with the first fan <NUM>.

Refer to <FIG>. <FIG> is a partial schematic structural three-dimensional view of an electronic device of the present invention. <FIG> is a schematic exploded view of <FIG>. In this embodiment, the heat dissipation module <NUM> further includes a heat conduction plate <NUM>. The heat conduction plate <NUM> is disposed between the first heat source <NUM> and the first heat conduction member <NUM>. Through the heat conduction plate <NUM> with a large-area contact between the first heat conduction member <NUM> and the first heat source <NUM>, heat of the first heat source <NUM> can be quickly transferred to the first heat conduction member <NUM>, thereby improving a heat conduction effect of the first heat conduction member <NUM>. In these embodiments, the heat conduction plate <NUM> is a plate-shaped body with an area greater than that of the first heat source <NUM>. In some embodiments, the heat conduction plate <NUM> is a copper sheet with a high thermal conductivity coefficient, but the present invention is not limited thereto.

Referring to <FIG>, in some embodiments in which the heat dissipation module <NUM> includes the heat conduction plate <NUM>, the area of the heat conduction plate <NUM> is greater than that of the through hole <NUM>. As shown in <FIG>, the heat conduction plate <NUM> completely covers the through hole <NUM>. The heat conduction plate <NUM> includes a first surface <NUM> and a second surface <NUM> configured oppositely. The heat conduction plate <NUM> is disposed on the upper surface <NUM> of the first case <NUM>, covers the through hole <NUM> with the second surface <NUM>, and abuts against the upper surface <NUM> around the through hole <NUM>. The first heat conduction member <NUM> abuts against the first surface <NUM> of the heat conduction plate <NUM>. The first heat source <NUM> is disposed at a position corresponding to the through hole <NUM> in the housing <NUM> and abuts against the second surface <NUM>.

In this way, the heat conduction plate <NUM> abuts against the upper surface <NUM> of the first case <NUM> to be stably supported and can contact the first heat source <NUM> at the same time. In these embodiments, the second surface <NUM> of the heat conduction plate <NUM> further includes a convex portion <NUM>. The shape and size of the convex portion <NUM> are smaller than those of the through hole <NUM>. When the second surface <NUM> of the heat conduction plate <NUM> abuts against the upper surface <NUM> of the first case <NUM>, the convex portion <NUM> of the heat conduction plate <NUM> penetrates into the through hole <NUM>, to exactly abut against the first heat source <NUM> located in the first case <NUM>.

In these embodiments, the shape of the groove <NUM> in communication between the through hole <NUM> and the penetrating hole <NUM> corresponding to the position of the through hole <NUM> corresponds to the shape of the heat conduction plate <NUM>, so that the heat conduction plate <NUM> can be assembled more easily and can be stably accommodated in the groove <NUM> to correspond to the through hole <NUM> and the first heat source <NUM>. In this way, it is also more convenient to fix the heat conduction plate <NUM> on the upper surface <NUM> of the first case <NUM> by various fixing means. As shown in <FIG>, an outer periphery of the heat conduction plate <NUM> is fixed to the first case <NUM> by a screw locking member.

Referring to <FIG>, in some embodiments, the electronic device further includes a circuit board <NUM>. The circuit board <NUM> is disposed in the housing <NUM> in a direction parallel to the lower surface <NUM>. The first heat source <NUM> and the second heat source <NUM> are respectively located on two opposite sides of the circuit board <NUM>. The first heat source <NUM> and the second heat source <NUM> are respectively disposed at different height positions in the housing <NUM>. In these embodiments, the first heat source <NUM> is disposed on a side of the circuit board <NUM> close to the lower surface <NUM>, and the second heat source <NUM> is disposed on a side of the circuit board <NUM> away from the lower surface <NUM>. In this way, the first heat source <NUM> and the second heat source <NUM> may be located at different height positions in the housing <NUM>. The first heat source <NUM> and the first fan <NUM> and the first heat conduction member <NUM> that are configured to dissipate heat from the first heat source <NUM> may be as close as possible to the upper surface <NUM> of the first case <NUM>. The second heat conduction member <NUM> configured to dissipate heat from the second heat source <NUM> may be configured at a position close to the second case <NUM>, so that heat from the first heat source <NUM> and the second heat source <NUM> at different height positions is fully dissipated through the heat dissipation module <NUM>, and the space utilization in the housing <NUM> can be improved. In some embodiments, the first heat source <NUM> and the second heat source <NUM> may be respectively, for example, a central processing unit or a display card, but the present invention is not limited thereto. In some embodiments, the first heat conduction member <NUM> and the second heat conduction member <NUM> are, for example, heat pipes or flat copper tubes with a high thermal conductivity coefficient, but the present invention is not limited thereto.

Refer to <FIG>. <FIG> is a partial cross-sectional view drawn along a cutting line <NUM>-<NUM> in <FIG>. In this embodiment, the electronic device further includes a combination unit <NUM> to combine the heat conduction plate <NUM> and the circuit board <NUM>, to ensure that the heat conduction plate <NUM> can exactly contact the first heat source <NUM> on the circuit board <NUM> under a predetermined pressure. In these embodiments, the circuit board <NUM> is not directly combined with the heat conduction plate <NUM>, but is combined with the heat conduction plate <NUM> through the combination unit <NUM>. In this embodiment, a relative position of the circuit board <NUM> relative to the heat conduction plate <NUM> is restrained by the combination unit <NUM> fixed on the heat conduction plate <NUM>.

Referring to <FIG>, in this embodiment, the combination unit <NUM> includes a combination member <NUM>, a fixing member <NUM>, and a locking member <NUM>. The combination member <NUM> includes a fixed section <NUM> and a cantilever section <NUM> that are joined. The fixing member <NUM> fixes the combination member <NUM> on the second surface <NUM> of the heat conduction plate <NUM> and defines the fixed section <NUM>. Two ends of fixed section <NUM> define the cantilever section <NUM> respectively. The locking member <NUM> runs through the circuit board <NUM> and is locked to the cantilever section <NUM>. In this way, since one end of the cantilever section <NUM> is connected to the fixed section <NUM> and the other end is a free end, when the locking member <NUM> is locked to the circuit board <NUM> by the cantilever section <NUM>, the end of the cantilever section <NUM> connected to the fixed section <NUM> limits the cantilever section <NUM> and a locking depth of the locking member <NUM> locked on the cantilever section <NUM>. The cantilever section <NUM> is limited by the fixed section <NUM> and can restrain the locking member <NUM> to prevent the circuit board <NUM> from damage due to an excessive locking force of the locking member <NUM>.

Referring to <FIG>, in some embodiments, the fixing member <NUM> of the combination unit <NUM> can be, but is not limited to, a rivet or a screw locking member. In these embodiments, two fixing members <NUM> are provided. The two fixing members <NUM> are disposed at a middle section of the combination member <NUM> and fixed to the heat conduction plate <NUM>. A range between the two fixing members <NUM> defines the fixed section <NUM>. A range between each fixing member <NUM> and two free ends of the combination member <NUM> is defined as the cantilever section <NUM>.

Referring to <FIG>, in this embodiment, the combination unit <NUM> is provided with two combination members <NUM>. Each combination member <NUM> has a long strip structure. The two combination members <NUM> are disposed on the second surface <NUM> of the heat conduction plate <NUM>. In this embodiment, the two combination members <NUM> are parallel to each other and are located on two opposite sides of the through hole <NUM>. In these embodiments, each combination member <NUM> is provided with two cantilever sections <NUM>. The cantilever sections <NUM> are respectively joined to two ends of the fixed section <NUM>. In this way, the combination unit <NUM> can use four locking members <NUM> to lock the circuit board <NUM> to the combination member <NUM> fixed on the heat conduction plate <NUM>. The locking members <NUM> may be disposed at a position corresponding to four corners of the through hole <NUM>, to improve the locking stability between the combination unit <NUM> and the circuit board <NUM>.

Referring to <FIG>, in some embodiments, the combination unit <NUM> further includes a nut <NUM>, disposed at an end of the cantilever section <NUM> away from the fixed section <NUM>. The locking member <NUM> runs through the circuit board <NUM> and is locked to the nut <NUM>, to facilitate the locking of the locking member <NUM>. In some embodiments in which the combination unit <NUM> includes a nut <NUM>, the nut <NUM> includes a sleeve portion <NUM> and a head portion <NUM> that are joined. The sleeve portion <NUM> includes an internal thread groove. The head portion <NUM> is a flat plate with an outer contour larger than that of the sleeve portion <NUM>. The nut <NUM> runs through the end of the cantilever section <NUM> away from the fixed section <NUM> through the sleeve portion <NUM> in a displaceable manner. After the locking member <NUM> runs through the circuit board <NUM> and is locked the sleeve portion <NUM> of the nut <NUM>, the nut <NUM> abuts against the heat conduction plate <NUM> and the combination member <NUM> with the head portion <NUM>. In these embodiments, the second surface <NUM> of the heat conduction plate <NUM> includes a plurality of positioning grooves <NUM>. The position of each positioning groove <NUM> corresponds to a locking position of the locking member <NUM>. The shape of each positioning groove <NUM> corresponds to that of the head portion <NUM> of the nut <NUM>. In this way, each positioning groove <NUM> can provide the nut <NUM> to be initially positioned on the heat conduction plate <NUM> during assembly. After the combination member <NUM> is fixed on the heat conduction plate <NUM> by the fixed section <NUM>, the cantilever section <NUM> can limit the nut <NUM> from falling off. In this way, the displaceable configuration of the nut <NUM> improves the floatability of the locking member <NUM> after being locked on the nut <NUM>, and can also simplify a manufacturing process of the combination member <NUM> and reduce production costs thereof.

In some embodiments, the nut <NUM> is not limited to running through the cantilever section <NUM> in a displaceable manner. The nut <NUM> may be the cantilever section <NUM> that only includes the sleeve portion <NUM> and is directly integrally formed on the combination member <NUM>. The present invention is not limited thereto.

It should be noted that since the circuit board <NUM> can bear different locking pressures, to adjust a locking pressure between the combination unit <NUM> and the circuit board <NUM>, the floating stroke of the cantilever section <NUM> can be changed accordingly by changing the material and thickness of the combination member <NUM> or the length of the cantilever section <NUM>, and then the locking pressure of the locking member <NUM> can be relatively controlled, thereby ensuring that the circuit board <NUM> is kept from damage due to the excessive pressure of the locking member <NUM>.

Referring to <FIG> and <FIG>, in some embodiments, the electronic device further includes two heat dissipation fin sets <NUM>. One heat dissipation fin set <NUM> is disposed in the penetrating hole <NUM> and is located at the first air outlet <NUM> of the first fan <NUM>. The other heat dissipation fin set <NUM> is disposed at the second air outlet <NUM> of the second fan <NUM>. In these embodiments, the end of the first heat conduction member <NUM> disposed at the first fan <NUM> abuts against the heat dissipation fin set <NUM> located at the first air outlet <NUM>. The end of the second heat conduction member <NUM> disposed at the second fan <NUM> abuts against the heat dissipation fin set <NUM> located at the second air outlet <NUM>. In this way, heat dissipation efficiency is improved through the configuration of the heat dissipation fin set <NUM>.

Referring to <FIG>, in this embodiment, the second case <NUM> includes a main frame <NUM> and a plate member <NUM>. The main frame <NUM> is disposed on the side wall <NUM>. The plate member <NUM> is detachably disposed on the main frame <NUM>. In this way, through the plate member <NUM> which is detachable, it is convenient for a user to replace or repair electronic parts in the housing <NUM> after removing the plate member <NUM>. In these embodiments, the main frame <NUM> is a plate-shaped structure with an outer contour corresponding to the contour of the side wall <NUM> to be assembled on the side wall <NUM>. The main frame <NUM> has a plurality of assembly openings <NUM>. The positions and shape of the assembly openings <NUM> correspond to various electronic parts in the housing <NUM>. The plate member <NUM> is detachably assembled in the assembly openings <NUM>, so that it is convenient for a user to disassemble the plate member <NUM> to replace or repair various components in the housing <NUM>.

Referring to <FIG>, in some embodiments in which the second case <NUM> includes the plate member <NUM> which is detachable, a plurality of plate members <NUM> may be provided. The positions of the plate members <NUM> may respectively correspond to the positions of the first fan <NUM>, the second fan <NUM>, and the second heat source <NUM>, so as to facilitate the repair or replacement of the first fan <NUM>, the second fan <NUM>, or the second heat source <NUM>.
