2, making that the air-conditioning system load is very high, the air-conditioning system energy consumption is big.Therefore how under the situation that satisfies the equipment instructions for use, effectively reducing computer or communication equipment computer-room air conditioning system energy consumption is the major issue that air conditioner industry faces.
The approach that reduces at present the computer-room air conditioning system energy consumption is a lot, for example optimizes the air blow and return mode, utilizes natural cooling source, optimal control technology etc., but exist such as shortcomings such as maintenance cost height, energy-saving effect are not obvious.The separate heat pipe system is by special pipe network connected mode, can guarantee that each several part cycle fluid temperature is basic identical in the heat pipe, the machine room inner air and outer air temperature difference is not higher than certain numerical value (as 5 ℃), guarantee that the interior temperature of machine room is lower than the upper limit of equipment requirement environment temperature, and low with its energy consumption, clean and be easy to make, be easy to advantage such as maintenance, become the preferred option of computer-room air conditioning system.Chinese patent CN 201093658 discloses a kind of heat extraction device for equipment room of separate heat pipe, adopt the separate heat pipe heat exchange of forced convection, make that cycle fluid evaporates, condensation in condenser in evaporimeter, realize the countercurrent flow of machine room inner air and outer air, the heat in the machine room is discharged to outside the machine room.But this patented technology still has the following disadvantages and defective: the one, and indoor evaporator adopts two-tube the connection with outdoor condenser, and two pipes are respectively the loop of gaseous state and liquid refrigerant, and this has brought inconvenience to installation and maintenance, has increased the cost of processing, installation simultaneously; The 2nd, the heat exchange DeGrain when indoor temperature during apparently higher than outdoor temperature or under the less temperature difference, adopts single group heat pipe just to seem powerless.
Summary of the invention
The purpose of this invention is to provide a kind of heat extraction device for equipment room that adopts the separate heat pipe countercurrent flow, not only installation and maintenance is convenient to make it, and can be under the less temperature difference or indoor temperature during apparently higher than outdoor temperature, can realize heat transfer outside machine room in the machine room with very high efficient.
Technical scheme of the present invention is as follows:
A kind of heat extraction device for equipment room that adopts the separate heat pipe countercurrent flow, this device comprises and is installed in evaporimeter, the evaporator fan in the machine room and is installed in machine room outer condenser and condenser fan, it is characterized in that: described evaporimeter and condenser all contain the above heat exchanger of at least two groups, the bottom of every group of heat exchanger in the condenser is communicated with by the top of every group of heat exchanger in vapour-liquid tube connector and the evaporimeter respectively, and corresponding one by one, form the heat exchange structure of the inner air and outer air adverse current of forming from the formula heat pipe by multicomponent.
In technique scheme, the interface of heat exchanger and vapour-liquid tube connector is higher than the interface of heat exchanger and vapour-liquid tube connector in the evaporimeter in the condenser; Described evaporator fan places the inlet or the outlet of evaporimeter, and described condenser fan places the inlet or the outlet of condenser,
The present invention has the following advantages and the high-lighting effect: 1. the present invention adopts the separate heat pipe that many group counter flow in series are arranged, and can be implemented under the less temperature difference, makes that the utilization rate of whole equipment room heat-extraction system increases, amount of energy saving increases and the raising of heat exchange efficiency.2. because the heat exchanger in the condenser adopts single gas-liquid tube connector to be connected with the interior heat exchanger of evaporimeter, compare the cost that has reduced processing and installed, the installation and maintenance of being more convenient for adopting two gas-liquid pipe tube connectors; 3. can realize that outdoor air is not in the inlet chamber, avoided the pollution problem of direct introducing air, also avoided the unmanageable problem of humidity of direct introducing air mode, compared with adopting heat-exchangers of the plate type, can realize lower heat transfer temperature difference, and be easy to more safeguard and cleaning.4. the present invention has only the blower fan power consumption (condenser forced convertion) of evaporimeter and condenser, when adopting the free convection formula, condenser then has only the evaporator fan power consumption, to compare energy-saving potential huge with the air conditioning mode of routine, and because its parts are formed simply, maintenance cost is very low.
