BACKGROUND

At present, a power supply for common mining machines, servers and other products has multiple fans installed on a main body of the power supply.

The housing121is connected to the chassis111through at least one of screw connection, magnetic connection, adhesive connection, and snap connection.

As shown inFIG.1andFIG.4, in an implementation, the second circuit board assembly122includes a substrate1221, a heat generating device1222, and a heat sink1223. The heat generating device1222is installed on a side of the substrate1221facing away from the heat conduction layer130, and the heat sink1223is connected to the substrate1221, and the heat sink1223abuts against the heat generating device1222. The heat generating device1222abuts against the heat sink1223, and when the power supply120is working, the heat generated by the heat generating device1222is conducted to the chassis111through the heat sink1223, and then dissipated by the heat dissipation fan assembly113installed on the chassis111.

As shown inFIG.1andFIG.4, in an implementation, the substrate1221is made of aluminum, or copper, or titanium alloy, and the heat sink1223is protrudingly disposed on a side of the substrate1221facing away from the heat conduction layer130, and the heat sink1223is installed or integrally formed on the substrate1221, the heat conduction layer130is coated and molded on a surface of the chassis111facing the second circuit board assembly122and/or coated and molded on a surface of the substrate1221facing the chassis111. The substrate1221provided in the present embodiment is an aluminum substrate, which is more suitable for a SMT process, and has a long service life and a high reliability. Certainly, in a specific application, it is not limited to the aluminum substrate, for example, as an alternative solution, the substrate1221may also be made of copper or titanium alloy. The heat sink1223is integrally formed on the substrate1221, which has a better heat dissipation effect and its processing is convenient. Of course, in a specific application, the substrate1221and the heat sink1223can also be processed separately, and then the heat sink1223is installed on the substrate1221.

The heat-conducting silicone grease has good thermal conductivity and insulation and can be used for a long time in a high and low temperature environment, and is beneficial for prolonging the service life of the server100to a certain extent. The heat conduction silicone grease is coated and molded on the outer surface of the chassis111, or coated and molded on the outer surface of the power supply120, or coated and molded both on the outer surfaces of the chassis111and the power supply120.

The heat dissipation fins1111are provided in the chassis111to improve the heat dissipation effect. Of course, in a specific application, the heat dissipation fins1111may not be provided in the chassis111, but the heat dissipation effect is worse than that the provision of the heat dissipation fins1111.

As shown inFIG.2andFIG.5, in an implementation, the chassis111is formed with an inner cavity1112, an air inlet1113, and an air outlet1114. The air inlet1113and the air outlet1114communicate with the inner cavity1112respectively, and the first circuit board assembly112is installed in the inner cavity1112, and the heat dissipation fan assembly113is arranged at the air inlet1113and/or the air outlet1114. The air inlet1113and the air outlet1114are respectively arranged on opposite sides of the chassis111, which is beneficial for forming convection, thereby forming a good ventilation and heat dissipation effect.

As shown inFIG.1andFIG.2, in an implementation, the heat dissipation fan assembly113includes a first fan1131and a second fan1132, the first fan1131is installed at the air inlet1113, and the second fan1132is installed at the air outlet1114.

The first fans1131installed at the air inlet1113draw air in, and the second fans1132installed at the air outlet1114draw air out, further improving the heat dissipation effect.

The following describes the working principle of the server100with reference toFIG.1.

When the server100is working, the second circuit board assembly122on the power supply120and the first circuit board assembly112on the server main body110generate heat; the heat generated by the second circuit board assembly122is directly conducted to the chassis111of the server main body110through the heat conduction layer130, the heat generated by the first circuit board assembly112and the second circuit board assembly122is dissipated by the heat dissipation fan assembly113installed on the chassis111. By sharing a fan, it is avoided to install a fan on the power supply120, so that the power supply120maintains a good sealing performance, thereby solving the problems of the corrosion of the power supply120and the high failure of the fan of the power supply120, improving the reliability of the power supply120, reducing the energy consumption of the whole machine and noise, improving the overall efficiency of the system, and reducing costs.

As shown inFIG.6andFIG.7, the present embodiment differs from Embodiment 1 in that the substrate1221is made of a different material, which is specifically reflected in the following.

As shown inFIG.6andFIG.7, in an implementation, the substrate1221is made of a resin, the second circuit board assembly122further includes a heat dissipation panel1224, and the heat dissipation panel1224is arranged on a side of the substrate1221facing away from the heat generating device1222. The heat sink1223is installed on the heat dissipation panel1224and extends through the substrate1221to abut against the heat generating device1222. The heat conduction layer130is coated and molded on the surface of the chassis111facing the second circuit board assembly122and/or the surface of the heat dissipation panel1224facing the chassis111. The substrate1221made of a resin is also called an epoxy resin plate. A circuit board made of the epoxy resin plate cannot directly conduct heat, so the heat dissipation panel1224needs to be added between the second circuit board assembly122and the chassis111. One end of the heat sink1223abuts against the heat generating device1222, and the other end passes through the substrate1221and abuts against one end of the heat dissipation panel1224, and the other end of the heat dissipation panel1224is attached to the surface of the chassis111through the heat conduction layer130. At this time, the heat generated by the heat generating device1222is first conducted to the heat dissipation panel1224through the heat sink1223, and then conducted to the chassis111by the heat dissipation panel1224for heat dissipation. The heat conduction layer130is coated and molded on the surface of the chassis111facing the second circuit board assembly122, or coated and molded on the surface of the heat dissipation panel1224facing the chassis111, or coated and molded both on the surface of the chassis111facing the second circuit board assembly122and the surface of the heat dissipation panel1224facing the chassis111.

The working principle of the server100is described below with reference toFIG.6.

When the server100is working, the second circuit board assembly122on the power supply120and the first circuit board assembly112on the server main body110generate heat; the heat generated by the second circuit board assembly122is conducted to the chassis111of the server main body110through the heat dissipation panel1224and the heat conduction layer130, the heat generated by the first circuit board assembly112and the second circuit board assembly122is dissipated by the heat dissipation fan assembly113installed on the chassis111. By sharing a fan, it is avoided to install a fan on the power supply120, so that the power supply120maintains a good sealing performance, thereby solving the problems of the corrosion of the power supply120and the high failure of the fan of the power supply120, improving the reliability of the power supply120, reducing the energy consumption of the whole machine and noise, improving the overall efficiency of the system, and reducing costs.

Except for the above differences, the structure of the server100and its components provided in the present embodiment can be optimally designed with reference to Embodiment 1, and will not be described in detail herein.
