In terms of heat dissipation, the built-in fans of traditional servers are cancelled, and centralized heat dissipation is adopted at the cabinet level to facilitate maintenance. At the same time, it provides temperature control speed regulation and partition heat dissipation functions to save energy and extend the service life of fans. Since a standard server mainboard power supply interface can be provided, the standard server mainboard can be directly used in the cabinet, and the price of the standard mainboard is relatively low, which can reduce the cost.

Contents of the invention

The purpose of the present invention is to provide a design method for an integrated cabinet with power supply and heat dissipation.

The purpose of the present invention is achieved in the following manner, and the design steps are as follows:

1) In the standard cabinet, centralized power supply is adopted. The power supply system is AC input and DC output power supply system. The DC output voltage is the power supply voltage of the unified standard server motherboard. At the rear of the cabinet, the DC output part of the power supply system is connected to the power rail. Then lead out several power adapter cables from the power rail to connect with the power supply interface of the unified standard server motherboard. The power system is located in the middle of the cabinet to ensure the shortest distance between the power system and each server motherboard; server motherboard;

2) In terms of heat dissipation, the built-in fan of the traditional server is canceled, and centralized heat dissipation is adopted at the cabinet level. The rear of the cabinet is a power rail and a fan, which is convenient for maintenance. At the same time, it provides temperature control and speed regulation and partition cooling functions to save energy and extend the service life of the fan;

3) A standard server motherboard power supply interface is provided, and the front of the chassis is a server unit, a power supply system and a monitoring system using the same standard server motherboard to reduce costs.

The beneficial effect of the present invention is: in terms of server power supply, considering from the cabinet level, a centralized power supply is adopted, and a unified power supply system is used to supply power to the server mainboard, which can improve power supply utilization, save energy, and is easy to manage. In terms of server heat dissipation, from the perspective of the cabinet, it adopts centralized heat dissipation, which is easy to manage. At the same time, it supports temperature control and speed regulation and partition heat dissipation, which saves energy and prolongs the service life of fans. Provide standard server motherboard power supply interface, you can use the standard server motherboard to configure the cabinet, the price of the standard motherboard is relatively low, which can reduce the cost.

Accompanying drawing 1 is the overall schematic diagram of the power supply and cooling integrated cabinet proposed in the present invention. As shown in the figure, the front of the chassis is the server unit using a standard server motherboard, the power supply system and the monitoring system, and the rear of the cabinet is the power rail and fan. Centralized power supply is adopted, the power supply system is AC input, DC output power supply system, and the DC output voltage is the power supply voltage of the standard server motherboard. Connect the DC output part of the power system to the power rail (as shown in Figure 2), and then lead out several power transfer cables from the power rail. One side of the power transfer cable is connected to the power rail, and the other side is the power supply interface of the standard server motherboard. The power system is located in the middle of the cabinet to ensure the shortest distance from the power system to each server motherboard. The power system output passes through the power rails to deliver power to the individual server boards.
