Detailed description of the invention
In detailed description of the invention below, with reference to the accompanying drawing that forms this description part.In the case of the principle and scope that do not depart from subject matter shown herein, in this article roughly describe and accompanying drawing in illustrated each aspect of the present invention can in wide in range configuration variation, arrange, replace, combine, break and abridge, all these arrange, replace, combination, partition and abreviation all fall into scope of the present invention within.
Fig. 1 is according to the structural representation of the heat exchanger 100 of one embodiment of the invention.Heat exchanger 100 comprises two Tube Sheet of Heat Exchanger, is respectively First Heat Exchanger pipe 102 and the second Tube Sheet of Heat Exchanger 104, and they interconnect in the mode that can carry out heat exchange, but are not communicated with each other.In the embodiment of Fig. 1, the caliber of First Heat Exchanger pipe 102 is identical with evaporator of refrigerator caliber or bigger,
The caliber of the second Tube Sheet of Heat Exchanger 104 is identical with condenser for refrigerator caliber or bigger.As shown in fig. 1, the miscellaneous part that First Heat Exchanger pipe 102 and the second Tube Sheet of Heat Exchanger 104 are connected in refrigerant loop by tube connector 101 and 103 respectively.It will be understood by those skilled in the art that other reasonable connected modes that also can adopt except tube connector.
In the embodiment of Fig. 1, First Heat Exchanger pipe 102 and the second Tube Sheet of Heat Exchanger 104 by and the mode of welding link together, thereby can carry out each other heat exchange.In an alternate embodiment, First Heat Exchanger pipe 102 and the second Tube Sheet of Heat Exchanger 104 are formed in same inflation plate in inflation mode, thereby can carry out each other heat exchange.The material of First Heat Exchanger pipe 102 can be identical with evaporator tube material, can be also copper.The material of the second Tube Sheet of Heat Exchanger 104 can be identical with condenser tube material, can be also copper.
Fig. 2 is according to the assembly drawing of the heat exchanger 100 of one embodiment of the invention, shows a kind of example connected mode of heat exchanger 100.As shown in Figure 2, be provided with compressor 106, evaporimeter 108 and condenser 110 in a unilateral system refrigerant circuit, they communicate with each other by this refrigerant loop, and heat exchanger 100 is also arranged in this refrigerant loop.In heat exchanger 100, one end of First Heat Exchanger pipe 102 is communicated with the refrigerant outlet of evaporimeter 108, is communicated with specifically the refrigerant outlet of evaporimeter 108 in the embodiment of Fig. 2 via return-air heat exchanger tube 116; And the other end of First Heat Exchanger pipe 102 is communicated with the refrigerant inlet of compressor 106, be communicated with specifically in this embodiment the refrigerant inlet of compressor 106 via return-air tube connector 112.The second Tube Sheet of Heat Exchanger 104 is communicated with condenser 110, but its refrigerant outlet that can be communicated in practice condenser 110 also can be communicated to the refrigerant inlet of condenser 110.With regard to the heat exchanger 100 in the embodiment of Fig. 2, one end of the second Tube Sheet of Heat Exchanger 104 is communicated with the refrigerant inlet of condenser 110, and the other end is communicated with the refrigerant outlet of compressor 106, be communicated with specifically the refrigerant outlet of compressor 106 via exhaust connection 114.The refrigerant outlet of condenser 110 is communicated with the refrigerant inlet of evaporimeter 108 successively by drier 120 and capillary 118.
In the embodiment of Fig. 2, in primary coolant circulation, cold-producing medium is discharged from the exhaust connection 114 of compressor 106, enters condenser 110 through the second Tube Sheet of Heat Exchanger 104; From condenser 110 flows out, flow through successively drier 120 and capillary 118, enter evaporimeter 108; From evaporimeter 108 flows out, the return-air heat exchanger tube 116 of flowing through successively, First Heat Exchanger pipe 102 and return-air tube connector 112, get back to compressor 106, completes circulation.As can be seen here, when saturated or when also unsaturated cold-producing medium flows into First Heat Exchanger pipe 102 from return-air heat exchanger tube 116, described cold-producing medium carries out heat exchange with HTHP (cold-producing medium) gas being drained into the second Tube Sheet of Heat Exchanger 104 from the exhaust connection 114 of compressor 106.In this heat exchanging process, can make unsaturation cold-producing medium complete saturation state on the one hand, make the further supersaturation of saturated cold-producing medium; Can reduce on the other hand the refrigerant inlet temperature of condenser 110.By utilizing the unsaturated cold-producing medium during from return-air heat exchanger tube inflow heat exchanger to carry out heat exchange with the high temperature and high pressure gas being drained into heat exchanger from compressor air-discharging tube connector, not only can improve the enthalpy of refrigerator refrigeration system, improve efficiency, but also can reduce the generation of condensation, liquid hammer.
Fig. 3 is according to the assembly drawing of heat exchanger 200 of the present invention, shows the another kind of example connected mode according to heat exchanger 200 of the present invention.Heat exchanger 200 is identical with heat exchanger 100, also comprises First Heat Exchanger pipe 202 and the second Tube Sheet of Heat Exchanger 204, and they interconnect in the mode that can carry out heat exchange, but are not communicated with each other.As shown in Figure 3, be provided with compressor 206, evaporimeter 208 and condenser 210 in a unilateral system refrigerant circuit, they communicate with each other by this refrigerant loop, and heat exchanger 200 is also arranged in this refrigerant loop.The difference of heat exchanger 200 and heat exchanger 100 is the connected mode of the second Tube Sheet of Heat Exchanger 204.One end of the second Tube Sheet of Heat Exchanger 204 is communicated with the refrigerant outlet of condenser 210, and the other end is communicated with the refrigerant inlet of evaporimeter 208, is communicated with successively specifically the refrigerant inlet of evaporimeter 208 by drier 220 and capillary 218.In the embodiment of Fig. 3, the refrigerant inlet of condenser 210 is directly connected with compressor 206 by exhaust connection 214.
In the embodiment of Fig. 3, in primary coolant circulation, cold-producing medium is discharged from the exhaust connection 214 of compressor 206, enters condenser 210; From condenser 210 flows out, flow through successively the second Tube Sheet of Heat Exchanger 204, drier 220 and capillary 218, enter evaporimeter 208; From evaporimeter 208 flows out, the return-air heat exchanger tube 216 of flowing through successively, First Heat Exchanger pipe 202 and return-air tube connector 212, get back to compressor 206, completes circulation.This embodiment is to make in return-air heat exchanger tube 216 the unsaturation cold-producing medium flowing out and the cold-producing medium that condenser 210 flows out carry out heat exchange, and one side makes cold-producing medium supersaturation, makes on the other hand that cold-producing medium is excessively cold prevents that liquid refrigerant from shifting to an earlier date shwoot.The method not only can be brought the effect of the embodiment in similar Fig. 2, and can enhance product performance equally.
Although the present invention is illustrated and is described with reference to specific embodiments, but those having ordinary skill in the art will appreciate that, without departing from the spirit and scope of the present invention in the situation that, can in specific embodiments, carry out the above and other variation aspect form and details, include but not limited to interpolation, minimizing or modified elements or substitute with equivalent.
