Description

A system dedicated to cooling a server

Technical field

The present invention relates to the technical field of data center equipment environment control, and in particular, to a system dedicated to heat dissipation of a server.

Background technique

China's data center is developing rapidly, with a total of more than 400,000. The annual electricity consumption exceeds 1.5% of the total electricity consumption of the whole society. It is estimated that the data center energy consumption will be equivalent to one year's power generation of the Three Gorges Power Station, most of which are data centers. The PUE is still generally greater than 2.2, which is a big gap compared with the international advanced level. Data center IT equipment needs to be cooled around the clock. Usually, precision air conditioners are used for cooling in the equipment room to ensure the environmental control requirements of the data center. The energy consumption of data center air conditioning units accounts for 35%-45% of the total energy consumption of the equipment room, second only to the energy consumption of IT equipment in the data center, resulting in higher data center PUE and low energy efficiency. In actual operation, the main heat dissipating component in the server is the central processing unit CPU, which dissipates about 80% of the total heat dissipation of the server. The remaining 20% is the cooling of the components in the server after removing the CPU, and the existing cooling of the data center. The method is usually to cool the environment and then re-cool the equipment. For example, the temperature requirements of Class A and Class B in the GB50174-2008 "Design Specification for Electronic Information System Room" are 23 °C ± 1 °C, because the heating points in the equipment room are not evenly arranged. In the equipment room, but mainly in the equipment and chips, the traditional cooling method can only cause the ambient temperature in the equipment room to drop, and the equipment itself does not form effective cooling, but the temperature of the equipment itself has not decreased or the speed of the decline is too Slow, still can not keep up with the heating rate of the device heating, resulting in energy loss and cooling effect, resulting in high local hot spot temperature, and did not reduce PUE.

At present, there is a cooling method in which the cooling water is concentrated in the cabinet, and the heat dissipation to the server is achieved by dissipating heat from the cabinet backplane. However, since the server needs to be installed at a certain distance from the cabinet backplane, the heat in the server is made. Can be blown out by the fan, which causes the cabinet to actually cool the air blown from the server port, which has low cooling efficiency, and this cooling method is to cover the entire backplane and cool all the servers in the cabinet. The server is not full, or the servers in the cabinet are not working at the same time, but the way the cabinet backplane is cooled does not recognize these phenomena, which leads to waste of energy.

Summary of the invention

The technical problem to be solved by the present invention is that the existing cooling method consumes a large amount of energy without lowering the temperature of the device itself, and the cooling effect is poor, and the purpose thereof is to provide a system dedicated to heat dissipation of the server, which system will naturally cool the wind and the wind. The combination of cooling technology of cold and cold water units uses a heat pipe radiator close to the heat source to cool the server. Through the reasonable organization of the airflow, the server-level cooling solution can effectively reduce the PUE and improve the energy efficiency utilization. It can effectively solve the problems of local hot spots caused by unreasonable airflow organization of precision air conditioning units; at the same time, it can effectively improve the space utilization of the equipment room, and can arrange more cabinets and servers, which can effectively improve the economic benefits and the effect of land saving.

The invention is achieved by the following technical solutions:

A system dedicated to dissipating heat from a server, comprising an outdoor natural cooling unit and an outdoor mechanical refrigeration unit, wherein the outdoor natural cooling unit and the outdoor mechanical refrigeration unit are sequentially connected with a voltage stabilizing unit, a pump unit, and a cold distribution heat exchange unit. The unit and the cold quantity distribution heat exchange unit are respectively connected with the corresponding outdoor natural cooling unit and the outdoor mechanical refrigeration unit and respectively constitute a loop; and further comprise a server backplane heat pipe heat dissipation unit, the server back plate heat pipe heat dissipation unit and the cold quantity distribution heat exchange Gravity heat pipes are arranged between the units, and the gravity heat pipes are simultaneously connected with the heat transfer unit of the server back plate and all the heat distribution heat exchange units, and the gravity heat pipes respectively contact the heat dissipation ports of the server and absorb and transfer the heat generated by the server to Cooling capacity distribution heat exchange unit. At present, there are two types of cooling methods in the equipment room. One is to use a precision air conditioner for cooling in the equipment room. This method can reduce the temperature in the equipment room, but consumes more energy, and does not cool down the heating point. The temperature of the local heating point is always high, and also occupies the space in the machine room. The space utilization rate of the equipment room is low. Another way is to concentrate the cooling water on the cabinet through water cooling, and through the cabinet backplane. Heat dissipation to achieve heat dissipation to the server. However, since the server needs to be installed at a certain distance from the cabinet backplane, the heat in the server can be blown out by the fan. This causes the cabinet to actually cool the air blown from the server port. Inefficient, and this cooling method is to cover the entire backplane, cooling all the servers in the cabinet, and the cabinet is not full of servers, or the servers in the cabinet are not working at the same time, while the cabinet backplane is cooled. The way is not to identify these phenomena, which leads to the waste of energy. At the same time, the machine room is equipped with precision parts with live operation. In the case of water cooling, the cooling water leaks, which will cause serious consequences. At the same time, due to the temperature difference of the pipe wall, water vapor will condense on the outer wall as water, and the water cooling method makes the whole cooling water pipe. The road has hidden dangers to the equipment in the equipment room. In this solution, the equipment is directly cooled by air cooling and natural cooling. The cooling efficiency is high and the equipment is not damaged. The natural cold source and air cooling are adopted outside the equipment room. The chiller cooling technology combines to achieve equipment-level heat dissipation, without water entering the equipment and causing equipment damage. Moreover, since each server is cooled correspondingly, it can be cooled for each server, that is, according to whether the server works or not, and the entire cabinet is not cooled, thereby improving the accuracy of cooling and reducing the accuracy. Energy consumption. The precision air conditioner can be completely replaced, and through the reasonable organization of the airflow, the server-level cooling solution can be used to effectively reduce the PUE and improve the energy efficiency utilization. On the other hand, it can effectively solve the unreasonable airflow organization of the precision air conditioning unit. At the same time, through the complete replacement of the air conditioning unit, the space utilization of the equipment room can be effectively improved, and more cabinets and servers can be arranged, thereby effectively improving the economic efficiency and the effect of saving land.

The heat dissipation of the components other than the CPU in the server is achieved by air conditioning of the heat pipe of the server backplane. Through the processing method of the heat pipe of the server backplane or the ceiling heat pipe, the safe and reliable operation of the equipment room can be ensured, and the natural cooling can be fully utilized, which greatly reduces the heat dissipation of the equipment room, saves the operating cost of the equipment room, and has low failure rate and maintenance. simple.

The server backplane heat pipe cooling unit includes a plurality of server backplane heat pipe evaporators, and each server backplane heat pipe evaporator is disposed corresponding to the heat dissipation port of each server and connected to the gravity heat pipe. The outdoor mechanical refrigeration unit and the outdoor natural cooling unit jointly assist the heat dissipation of the server, and adopt a two-stage heat exchange system. Under the action of the pump unit, the outdoor natural cooling unit and the outdoor mechanical refrigeration unit will heat the heat exchanger of the server back plate heat pipe. The heat generated in the unit is carried into the natural environment, which is the first-stage cyclic process; other devices other than the server CPU chip generate heat through the heat pipe unit of the server backplane, and are transferred to the server backplane heat pipe under the efficient heat transfer of the gravity heat pipe. The cold distribution heat exchanger, which is the second stage of the cycle.

The heat pipe of the server backplane takes heat from other parts of the server out of the equipment room to assist heat dissipation to the heat transfer of the heat pipe of the server backplane. The circulating water is cooled by the outdoor cooling device; the outdoor cooling unit is a natural cooling unit or a chiller. According to the working conditions of the ambient temperature, the two valves can be switched and used together to further apply the natural cold source to achieve energy saving; the outdoor natural cooling unit, the air-cooled chiller unit and the pump unit can be controlled by the frequency conversion technology. The return water temperature ensures the safety of the system. The fan of the heat pipe cooling system of the server backplane is stepless DC variable speed, which automatically adjusts the speed and automatically adjusts the heat dissipation.

In the case where the server generates less heat and the ambient humidity is high, the heat pipe unit of the server backplane may form a small amount of condensed water. Therefore, a condensate water collecting tray and a condensate drain pipe are disposed at the bottom of the heat pipe evaporator of the server backboard.

The cold distribution heat exchange unit is disposed between the outlet water distribution valve of the cold distribution heat exchanger and the inlet of the cold water distribution heat exchanger inlet bypass valve and the circuit. The cold water distribution heat exchanger outlet bypass valve and the cold distribution heat exchanger inlet bypass valve regulate the water inlet and outlet water to ensure the normal operation of the cold distribution heat exchanger, the natural cooling unit and the mechanical refrigeration unit.

Between the cold distribution heat exchange unit and the outdoor natural cooling unit, between the cold distribution heat exchange unit and the outdoor mechanical refrigeration unit, set to the corresponding position as needed.

In the multi-stage heat exchange system of the scheme, the chilled water in the heat exchanger of the heat transfer of the heat pipe of the server backplane does not enter the machine room, thereby eliminating the danger of water entering the machine room or even equipment.

When the system is started, if it is to be used with the heat sink of the CPU, first start the heat pipe unit of the server backplane, and finally start the heat sink of the server CPU to avoid partial condensation of the heat sink close to the CPU chip; First, stop the CPU cooling device of the server, avoid condensation on the heat sink of the micro heat pipe, and finally stop the heat pipe cooling unit of the server backplane.
