Abstract
The utility model discloses a novel shell-and-tube heat exchanger, which comprises a heat exchanger body. A coolant inlet and a coolant outlet are arranged on the heat exchanger body, and a coolant flowing direction switching device which is capable of leading the coolant to flow into the heat exchanger body through the coolant inlet and leading the coolant to flow out of the heat exchanger body through the coolant outlet under both refrigerating and heating working conditions is arranged on the heat exchanger body. The novel shell-and-tube heat exchanger is simple and reliable in structure and low in cost and capable of realizing that the coolant flows into the heat exchanger from the coolant inlet no matter an air conditioner is in refrigerating or heating, and accordingly accumulation of excessive compressor oil inside the heat exchanger is avoided.
Description
Technical field
The utility model relates to a kind of novel pipe shell type heat exchanger that is used for air-conditioner.
Background technology
Along with the progress of processing technology, shell-and-tube heat exchanger develops toward miniaturization, high efficiency direction, is used widely in family expenses central air-conditioning, business air conditioner field.At present, common on the market shell-and-tube heat exchanger is the common tube shell heat exchanger or has set up the heat exchanger of band reservoir function on the basis of common tube shell heat exchanger, the latter is applicable to that more refrigerant pipe is long, the coolant injection amount is more, the refrigerant demand changes air-conditioning system greatly, and this has strengthened the market competitiveness of shell-and-tube heat exchanger greatly.Yet, above-mentioned heat exchanger all is only applicable to single cold or single heat air conditioner, because, changes in temperature switch type air-conditioner is after the cross valve commutation, the refrigerant side flow direction of turnover shell-and-tube heat exchanger can change, that is to say that if refrigerant end entrance from the shell-and-tube heat exchanger when heating, refrigerant will be from the shell-and-tube heat exchanger bottom inlet when refrigeration.If from the shell-and-tube heat exchanger bottom inlet, refrigerant sharply reduces at the inner flow velocity of shell-and-tube heat exchanger, the compressor oil that accumulates in heat exchanger inside can't be taken back compressor, the compressor oil starvation can take place in the air-conditioning long-play, and system reliability can't be guaranteed.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of novel pipe shell type heat exchanger.
Its technical solution is:
A kind of novel pipe shell type heat exchanger, comprise heat exchanger body, heat exchanger body is provided with refrigerant inlet and refrigerant outlet, also be provided with on the described heat exchanger body adjust cold-producing medium under refrigeration and heating condition by refrigerant inlet inflow heat exchanger body and by the refrigerant flow direction converting of refrigerant outlet outflow heat exchanger body.
Above-mentioned refrigerant flow direction converting comprises two I/O pipelines, and one of them I/O pipeline connects two branch lines, and a branch line is provided with the check valve of conducting, and another branch line is provided with the check valve that ends; Two branch lines of the same connection of another I/O pipeline, a branch line is provided with the check valve of conducting, and another branch line is provided with the check valve that ends; Two branch lines that the check valve of conducting all is set on it are communicated with the back and insert refrigerant inlet, and two branch lines that the check valve that ends all is set on it are communicated with the back and insert refrigerant outlet.
Useful technique effect of the present utility model is:
The utility model realizes air conditioner refrigerating or when heating, cold-producing medium makes heat exchanger body inside not have multi-compressor oil and accumulates all from refrigerant inlet inflow heat exchanger body; And the utility model is simple and reliable for structure, and is with low cost, only needs four check valves, and need not control signal; In addition, change the utility model and need not to change circuit part in the past, can shorten product development cycle greatly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is a structural principle schematic diagram of the present utility model.
The specific embodiment
In conjunction with Fig. 1, a kind of novel pipe shell type heat exchanger, comprise heat exchanger body 1, upper end at heat exchanger body 1 is provided with refrigerant inlet, bottom at heat exchanger body 1 is provided with refrigerant outlet, also be provided with on the heat exchanger body 1 adjust cold-producing medium under refrigeration and heating condition by refrigerant inlet inflow heat exchanger body and by the refrigerant flow direction converting 2 of refrigerant outlet outflow heat exchanger body.
Above-mentioned refrigerant flow direction converting 2 comprises two I/O pipelines of A, B, wherein, A I/O pipeline connects two branch lines, and a branch line is provided with first check valve 201 of conducting, and another branch line is provided with second check valve 202 that ends; Two branch lines of the same connection of B I/O pipeline, a branch line is provided with the 3rd check valve 203 of conducting, and another branch line is provided with the 4th check valve 204 that ends.First check valve 201 that conducting is set on it is communicated with the back and inserts refrigerant inlet with two branch lines of the 3rd check valve 203, second check valve 202 that ends is set on it is communicated with access refrigerant outlet in back with two branch lines of the 4th check valve 204.
As shown in Figure 1, the flow direction of cold-producing medium in pipeline during solid arrow indication refrigeration, the flow direction of cold-producing medium in pipeline when the dotted arrow indication heats.During refrigeration: cold-producing medium flows into from the A end, 201 conductings of first check valve, and the 202 not conductings of second check valve from shell-and-tube heat exchanger body 1 upper end inflow heat exchanger body 1, are flowed out from the bottom after heat exchange is finished, 204 conductings of the 4th check valve, cold-producing medium flows out from the B end; Refrigerant pressure reduces after the heat exchange, and second check valve 202 and the 3rd check valve 203 all can't conductings.When heating: cold-producing medium flows into from the B end, 203 conductings of the 3rd check valve, and the 204 not conductings of the 4th check valve from shell-and-tube heat exchanger body 1 upper end inflow heat exchanger body 1, are flowed out from the bottom after heat exchange is finished, and 202 conductings of second check valve are flowed out from the A end; Refrigerant pressure reduces after the heat exchange, and first check valve 201 and the 4th check valve 204 can't conductings.
Equally, present embodiment can be expanded to flow to the heat exchanging device has in the heat exchanger structure of requirement.
Need to prove, any equivalent way that those skilled in the art have done under the instruction of this specification, or obviously variant all should be in protection domain of the present utility model.
