       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1  is the structural schematic of the present disclosure. 
     
    
    
     Reference Numerals:  1 , euthermic chip;  2 , connector;  3 , motherboard;  4 , external structure. 
     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The embodiments of the disclosure will be described below in detail in conjunction with the accompanying drawings, but the disclosure may be implemented in many different ways defined and covered by Claims. 
     In the process of various types of computer product design, the present disclosure does not take the motherboard as a shaped component, but to classify the heat components (CPU, chipset, rectifier tube, on-board graphics card, etc.) and non-heating components (connector, IO interface, etc.) of the motherboard and adopt three-dimensional arrangement on double side to separate and disperse the heat sources to make full use of the mutual cooperation between cooling device and cooling space, in order to optimize the product overall design for larger implementation space of the heat dissipation management. 
     After determining the specifications of the motherboard, the secondary development and revision is carried out according to the public PCB issued by the motherboard chip supplier. Euthermic chips  1  are classified according to the size of its heat and operating temperature range to match the power of the heat dissipation device used. At the same time, taking into account the size specifications and position of connector  2 , in the condition of forming a smooth air flow channel as far as possible, the euthermic chips arrange on both sides of the motherboard  3 . Different from the conventional application of line design software in a single and flatten mode, a double-side design needs a three-dimensional consideration. In a specific implementation process, two technical solutions are usually used. One is to keep the chipset in the original side, while modify the pin definition of the connector. The other is to keep the connector in the original side, while realize the reversal mirror of the chip. 
     The above-mentioned changes in the layout of the motherboard cause changes in the internal structure and appearance of the product, and directly change the homogenization of the product and improve the market competitiveness of the product. 
     Because the chips attached to the PCB is relatively consistent in height of shape and the difference with the connectors thereof is large, classifying the high heat dissipation chip with the layout on the other side can improve the applicable processing conditions of heat dissipation devices, reduce the complexity, and fully avoid the heat dissipation barrier formed by components, such as cards attached to the original motherboard, and cables. Classifying the chip with low heat can reduce the heat in ambient space, and greatly reduce the balance point of exchange with the external air, after the high heat source is separated. 
     The motherboard designed by the disclosure removes the constraints and qualifications from the traditional motherboard. Therefore, the application of various heat dissipation management measures to reduce the cooling energy consumption and improve heat dissipation efficiency becomes more flexible. This motherboard can be arranged in different orientations inside the product, for example, the up, middle, and down, or the left, middle, and right. For example, to arrange the high heating surface on the outside of the product (up, down, left, right, back, and forth) can make the cooling device and the external structure  4  connected together, make the cooling channel directly to the outside, and the original heat from the chip to the inside of the product, and then to the outside of the product by the power fan is changed. To be arranged in the middle of the product, a smoother air flow channel can be designed to facilitate the planning of the air path. 
     In the new structure above, due to the separation of heat and better use of the external structure  4  and the environment, heat dissipation efficiency and cost power consumption are optimized under the conditions the same total heat generation of the product. For example, the original which needs a strong discharging active heat dissipation turns into a power saving passive cooling, it not only solves the heat accumulation but also eliminate the fan noise and the negative heat dissipation results brought by dust, and truly achieve the implementation effect of low-carbon green environmental protection. In addition, it also changed the situation of fixing the heat dissipation device to the fragile motherboard  3 , thus improving the reliability of the product. 
     In short, after the adoption of the present disclosure, compared with conventional computer heat management methods, there are different degrees of optimization and improvement in the three major evaluation elements of complexity, flexibility, implementation effect. 
     The disclosure breaks the original design thinking trend of the motherboard, realizes the scattered arrangement of the heating components on the motherboard, improves the heat accumulation condition inside the product in essence, makes the cooling channel more direct, and significantly improves the heat dissipation cost, power consumption, conduction medium and reliability of the product. For example, to use the laminated multi-board technology for the layout of the mainboard, the CPU, GPU, memory, SSD, South Bridge, North Bridge could be arranged respectively in different directions and in the correct position (e.g. front and back) with respective layout in different layers to achieve the purpose of disclosure. 
     The above are only the preferred embodiment of the disclosure and are not intended to limit the disclosure, for those skilled in the art, various changes and variations may be made to the disclosure. Any revisions, equivalent replacements, improvements and the like within the spirit and principle of the disclosure shall be contained within the scope of protection of the claims of the disclosure.
