Active heat pipe back plate cooling system

Abstract

The invention provides an active heat pipe back plate cooling system. The system comprises an outdoor unit system, and at least one heat pipe back plate system connected with the outdoor unit system, wherein the outdoor unit system comprises a condenser with a fan, and a circulating pump; the inlet end of the condenser is connected with the outlet end of the circulating pump; the back plate system comprises an air-liquid shunt, an evaporator, a fan and a circuit control system; an air return pipe is communicated between the air-liquid shunt and the evaporator; the outlet end of the air return pipe is connected with the outlet end of the evaporator; the inlet of the air-liquid shunt is connected with the outlet end of the condenser through an electric adjusting valve; and the liquid outlet end of the air-liquid shunt is connected with the inlet end of the evaporator. The system has the following beneficial effects: the system is near a heat source, so that the air return temperature is high; the year operation time of a heat pipe is prolonged; the cooling effect is good; the efficiency is high; the energy is saved; heat points of a machine room are reduced to the greatest extent; the environmental temperature of the machine room can rise up; and the electricity consumption of an air conditioner is largely reduced.

Description

technical field [0001] The invention relates to an active heat pipe back plate cooling system. Background technique [0002] The computer room is in a long-term working state and requires an air-conditioning system to cool it, but the air-conditioning system consumes a lot of energy, and the energy consumption of air-conditioning in a traditional computer room accounts for 40%. Usually, in order to save energy, some computer rooms use heat pipe equipment for supplementary cooling, and outdoor cooling sources can be used in low temperature seasons. However, since the heat pipe equipment is limited by the refrigerant delivery distance and the height difference between the inner and outer heat exchangers, the direct cooling application of remote cabinet equipment is limited. Therefore, the equipment can only be cooled indirectly by controlling the room temperature in the computer room. However, the heat generated by each device is uneven, and the airflow in the computer room ...

AI Technical Summary

Problems solved by technology

However, the heating of each device is uneven, and the airflow in the computer room is complicated. In order to ensure that all the devices work normally, the room temperature needs to be controlled to be very low, resulting in a great waste of electric energy.

For some large computer rooms, there is also a cold water backplane structure that can directly cool the equipment in the cabinet. However, this structure uses cold water for heat exchange, which has low safety performance. Compared with heat pipes, the performance is not as good
