Technical field
The utility model relates to a kind of anti-condensation refrigerant circulating heat pipe system, belongs to heat-pipe refrigerating backplane technology field.
Background technology
The heat-pipe refrigerating backplane technology is mainly used in communications equipment room, particularly IDC machine room, data machine room and BOS computer floor, because high-power rack is all adopted in these places, caloric value is big, and the caloric value of rack part is very big, by at rack the heat-pipe refrigerating backboard being installed, solved the difficult problem of machine room hot-spot, improve the utilization ratio of air-conditioning system, reduced the power consumption of Air Conditioning Facilities, realized energy efficiency.
Because the heat-pipe refrigerating backboard is directly to be installed on the rack tailgate, there is not the potential safety hazard of leaking in the machine room in order to make, technology is to adopt the heat-pipe refrigerating back board system of refrigerant circulation comparatively reliably at present, its operation principle is: refrigerant is after the evaporimeter that is built in backboard absorbs the rack heat of vaporization, circulate by gravity assisted heat pipe, flow to outdoor backboard water-cooled condenser, and by the low-temperature cold water that outside chilled water system provides the refrigerant heat is taken away condensation, under the gravity assisted heat pipe ringing, flow back to the backboard evaporimeter again and produce cold, high-power rack is cooled off.In general chilled water system is whole building air conditioning water system, except supplying with heat pipe backboard cold water source, also to other some air-conditioning equipments such as the constant low-temperature receiver that 7 ℃ of leaving water temperatures are provided such as precision air conditioner, fan coil in building.
Because carrying out the water source of the water-cooled condenser of heat exchange with the heat-pipe refrigerating backboard is the water of 7 ℃ of water temperatures, if the water of 7 ℃ of water temperatures directly enters water-cooled condenser and heat pipe backboard cold-producing medium carries out heat exchange, then the temperature of water-cooled condenser refrigerant outlet can be quite low.After so refrigerant of low temperature enters machine room by refrigerant pipe, make pipeline and heat pipe back plate surface be lower than the dew point in the machine room and cause condensation, will produce serious potential safety hazard to the information technoloy equipment in the machine room.
As shown in Figure 1, in order to solve the condensation problem of heat pipe back board system, prior art is the 7 ℃ of water outlets of cooling-water machine with natural cooling source, by externally increasing one-level Intermediate Heat Exchanger 9 between chilled water system and the backboard water-cooled condenser 3, become 12 ℃ water, enter water-cooled condenser 3 with the heat exchange of heat pipe backboard by 12 ℃ water, carry out heat exchange with the heat pipe backboard, in order to improve the outlet temperature of back board system water-cooled condenser 3 refrigerants, the backboard refrigerant pipe 4 in the prevention machine room 1 and backboard evaporimeter 2 dewfall occurs the machine room information technoloy equipment are caused potential safety hazard.This present technology needs the extra one-level Intermediate Heat Exchanger 9 that increases, and the installing space of heat exchanger need increase, owing to increased the one-level Intermediate Heat Exchanger, the utilization rate of low-temperature receiver reduces greatly simultaneously.And also to increase water circulating pump in the water system, and it is more complicated that installation pipeline also becomes, and cost is higher; In addition, owing to adopt fixing water temperature control, if the machine room air humidity changes, make the air dew point temperature rise to the design water temperature when above, be lower than the problem that air dew point causes condensation thereby outlet refrigerant temperature still might appear in heat pipe refrigerant system.Therefore, be necessary to be further improved.
