Abstract
The utility model discloses a kind of heat interchanger pick-up unit, the technical matters that solve is can Timeliness coverage defective products, avoids waste cold-producing medium and test resource.For solving the problem, the utility model realizes by the following technical solutions: a kind of heat interchanger pick-up unit, this pick-up unit comprises refrigerant cylinder, and the valve of described refrigerant cylinder is connected with connecting refrigerant lines, and described connecting refrigerant lines is flexibly connected with the intake header of heat interchanger.Compared with prior art, adopt and connect refrigerant cylinder at the enterprising connecting refrigerant lines of intake header, heat exchanger carries out preliminary filling, make it possible to the U-shaped curved link circuit of Timeliness coverage and whether kapillary blocks, Timeliness coverage defective products, avoid cannot testing at the trial, thus save test resource.
Description
Technical field
The utility model relates to a kind of air-conditioning system pick-up unit, especially a kind of heat interchanger pick-up unit.
Background technology
Air-conditioning comprises compressor, condenser, restriction device, and the large parts of evaporator four, realize cooling and warming by cold-producing medium in the circulation of air-conditioning system.The refrigerant gas of High Temperature High Pressure needs condenser to dispel the heat, and the refrigerant liquid of low-temp low-pressure needs evaporator to absorb heat, and cold-producing medium realizes liquid phase conversion by the forced heat-exchanging of heat interchanger within air-conditioning systems.General fin type heat exchanger is used in the air-conditioning equipment of forced air convection heat exchange.Evaporator in air-cooled air conditioner and condenser all use fin type heat exchanger.Carry out heat exchange by the forced convertion of air, reach the object of the cooling and warming of air-conditioning system.There is multiple loop in the heat interchanger of general air-conditioning, the import of heat interchanger has intake header, dispensing head, and kapillary forms, and outlet has discharge, and outlet header is formed.Cold-producing medium enters from intake header, and then dispensing head shunting, because the heat exchange efficiency of heat interchanger each position is different, the quantity of the cold-producing medium therefore needed is also inconsistent, inconsistent by the length of kapillary, realize the current-sharing of heat interchanger inner refrigerant, make the heat transfer effect of heat interchanger best.One end welding kapillary of heat interchanger and discharge, the other end is by U-shaped curved composition loop.By the U-shaped curved link circuit of human weld, may make a fault, cause the inner dead loop of heat interchanger device, cold-producing medium can not flow through corresponding region, thus can not effectively heat exchange.And kapillary is when welding on heat exchangers, also may there is blocking, but can not detect.Could find that part heat interchanger can not heat exchange in the test of laboratory heat pump performance, thus the cold-producing medium of exhaust system, rectify and improve, can cause like this wasting cold-producing medium and test resource.
Summary of the invention
The purpose of this utility model is to provide a kind of heat interchanger pick-up unit, and the technical matters that solve is can Timeliness coverage defective products, avoids waste cold-producing medium and test resource.
For solving the problem, the utility model realizes by the following technical solutions: a kind of heat interchanger pick-up unit, this pick-up unit comprises refrigerant cylinder, and the valve of described refrigerant cylinder is connected with connecting refrigerant lines, and described connecting refrigerant lines is flexibly connected with the intake header of heat interchanger.
The two ends of connecting refrigerant lines described in the utility model are respectively equipped with the female bonnet of tool, and bonnet is threaded with the valve of refrigerant cylinder and intake header respectively.
The utility model compared with prior art, adopt and connect refrigerant cylinder at the enterprising connecting refrigerant lines of intake header, heat exchanger carries out preliminary filling, make it possible to the U-shaped curved link circuit of Timeliness coverage and whether kapillary blocks, Timeliness coverage defective products, avoid cannot testing at the trial, thus save test resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, this pick-up unit of the present utility model comprises refrigerant cylinder 1, and the valve of described refrigerant cylinder 1 is connected with connecting refrigerant lines 2, and described connecting refrigerant lines 2 is flexibly connected with the intake header 3 of heat interchanger.
The two ends of connecting refrigerant lines 2 are respectively equipped with the female bonnet 4 of tool, and bonnet 4 is threaded with the valve of refrigerant cylinder 1 and intake header 3 respectively.
During use, open the valve of refrigerant cylinder, make liquid refrigerants flow through dispensing head 5, kapillary 6 enters heat interchanger; Become gaseous state through U-shaped curved, discharge and outlet header again to get rid of.
When liquid refrigerants flows through heat interchanger, meeting evaporation endothermic, causes heat exchanger surface frosting.If kapillary blocking, or U-shapedly curvedly have dead loop, then the surface of this loop heat exchanger can not frosting.Judge whether heat interchanger has problem thus.
The utility model result is simple, easy to operate, can not only Timeliness coverage defective products before the test, avoid waste test resource, but also it is short to have detection time, can not cause the excess waste of cold-producing medium.
