Description
Technical field
The utility model relates to a kind of heat exchanger, especially is used as the heat exchanger of splitting heat pump air conditioner outside condenser.
Background technology
At present, in single cold air conditioning system, generally refrigerant is taked less distribution stream to the outside design of condenser time, this not only can improve degree of supercooling, can also reduce the pressure loss of shunting.This is because gaseous coolant is high pressure conditions in condenser, specific volume is little, the flow path resistance loss of the heat exchanger same length as evaporator duty of comparing is little, same flowpath pressure loss is little so condenser and evaporimeter are compared, and the condensation stream that refrigerant passed through is long more, can form bigger degree of supercooling, this can effectively reduce the mass dryness fraction behind the coolant throttle, reduces loss of refrigeration capacity.But this design can only be at single cold air conditioning system, situation was just just opposite when heat pump type air conditioner system was heated, because when heat pump heats, outdoor condenser has just become evaporimeter, at this moment, the refrigeration stream inlet that is connected the refrigerant passage on the heat exchanger is as heating flow export, refrigeration stream outlet is as heating inflow entrance, if at this moment the distribution stream of outside condenser is less, the pressure that very long evaporation stream produces falls and can cause very big evaporating temperature to reduce, and according to thermodynamic principles, evaporating temperature reduces, can cause heat pump to reduce, thereby reduce the heat pump heating capacity in outdoor heat exchange amount.So when heat pump is worked, just need reduce the refrigerant flow path resistance of evaporimeter as far as possible, allow refrigerant in parallel exactly by many distribution streams and address this problem the most effective way.
Therefore in heat pump type air conditioning system, the stream distribution design of outdoor heat exchanger is a contradiction very, unfavorable to the favourable refrigerant flow that freezes to heating, unfavorable to heating favourable refrigerant flow to freezing, in the existing air-conditioning, when the pipe type heat exchanger refrigerant that uses distributed the stream assembling to finish, refrigerant flow process was therein just determined, can't be changed according to the heat exchange actual conditions.So present design is to take into account refrigeration, the efficient when heating, and the distribution flow path designs of heat pump type air conditioning system is become median.For example the condenser refrigeration is divided two streams, heat branch four streams and can make refrigeration, heat respectively and well mated, in practice, general three streams that just adopt as shown in Figure 1: three convection current pipeline joints promptly are set on heat exchanger, every convection current pipeline joint comprises an import and an outlet, the import of each convection current pipeline joint and outlet are communicated with in twos by internal flow path, during refrigeration, the general import of refrigerant outside heat exchanger enters heat exchanger by distributed outside pipeline and the runner interface that is arranged on the heat exchanger, through the runner interface, distributed outside pipeline and general export flow out; When heating, the general export of refrigerant outside heat exchanger by the distributed outside pipeline and be arranged on heat exchanger on the runner interface enter heat exchanger, flow out through runner interface, distributed outside pipeline and general import, and compromise consequence is, refrigerating efficiency can not be given full play to, heating efficiency can not be given full play to.
The utility model content
In order to overcome the deficiency that existing heat pump type air conditioning system outdoor heat exchanger stream distribution design is not enough to give full play to its cooling and warming efficient, technical problem to be solved in the utility model provides a kind of a kind of heat exchanger that can improve refrigeration and heating efficiency simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: heat exchanger, heat exchanger, heat exchanger is provided with the runner interface, each runner interface is communicated with by the internal heat exchange tubes road, each runner interface also is connected to general import, general export by the distributed outside pipeline, between general import and general export, form refrigerant flow, be assigned to the stream that stream that the refrigerant in the internal heat exchange tubes road forms forms more than in refrigeration the time when heating through the distributed outside pipeline.
The beneficial effects of the utility model are: on the basis of existing heat exchanger, by the convection current pipeline joint, the optimal design of internal heat exchange tubes road and distributed outside pipeline, in the time of can realizing this heat exchanger as heat pump air conditioner outside condenser, refrigeration and the stream conversion on internal heat exchange tubes road when heating, be assigned to the stream that stream that the refrigerant in the internal heat exchange tubes road forms forms more than in refrigeration the time through the distributed outside pipeline when heating, thereby the heat exchange efficiency of heat exchanger when freezing and heating is improved, realized the refrigeration of heat pump air conditioner, the output effect that heating capacity is optimized has simultaneously improved the heat exchange efficiency of heat exchanger.
