The specific embodiment
Extremely shown in Figure 8 as Fig. 2, heat exchanger comprises cooling fins 2 and is arranged in the interior double refrigerant line 1 of described cooling fins, described heat exchanger comprises that also one will flow into the triple valve 14 that cold-producing medium is divided into two-way, first branch road of described double refrigerant line 1 through first port 4 from the interior row's 17 of refrigerant line 1 middle and upper part along in be discharged to the top of arranging in reaching, and through efflux 16 tops of first tube connector 3 to refrigerant line 1, arrive the third connectivity mouth 6 that effluxes the middle part from the top that effluxes along effluxing again, second branch road of described double refrigerant line 1 through second port 7 from interior row's middle and lower part along in be discharged to the middle and upper part of arranging in reaching, and connect 5 through second and manage and efflux the middle part, efflux the middle and lower part along effluxing again from middle part arrival, arrive interior row middle and lower part through the 3rd tube connector 8 again, again through the 4th tube connector 9 to effluxing the middle and lower part, again from effluxing the middle and lower part along effluxing up to the four-way mouth 11 that effluxes the bottom; Described heat exchanger comprises that also one is combined into one tunnel triple valve 15 with third connectivity mouth 6 and four-way mouth 11, stream after the described merging through five-way mouth 10 from interior row bottom along in be discharged to reach in row bottom, and through the 5th tube connector 12 around to effluxing the bottom and through 13 outflows of the 6th port.
When air conditioner refrigerating, cold-producing medium is through triple valve 14, be divided into the two-way inflow heat exchanger, first via cold-producing medium flows to interior row's top earlier from interior row's middle and upper part from first port 4 of heat exchanger, and through first tube connector 3 around to effluxing top, flow to the middle part third connectivity mouth that effluxes 6 again from the top that effluxes and flow out, in through triple valve 15 converges to five-way mouth 10 after, flowing to bottom the row from interior row bottom, and through the 5th tube connector 12 around to effluxing the bottom and by 13 outflows of the 6th port.The second road cold-producing medium flows to interior row's middle and upper part earlier from interior row's middle and lower part from second port 7 of heat exchanger, and through second tube connector 5 around to efflux the middle part, flow to and efflux the middle and lower part from effluxing the middle part again, again through the 3rd tube connector 8 around to interior row middle and lower part, again through the 4th tube connector 9 around to effluxing the middle and lower part, flow to and efflux the bottom and flow out from effluxing the middle and lower part again by four-way mouth 11, row bottom in after triple valve 15 converges to five-way mouth 10, flowing to from interior row bottom, and through the 5th tube connector 12 around to effluxing the bottom and by 13 outflows of the 6th port.
When air-conditioning heats, cold-producing medium flows into from the 6th port 13, through the 5th tube connector 12 around bottom interior row, the five-way mouth 10 of row bottom in flowing to flows to third connectivity mouth 6 and the heat exchanger four-way mouth 11 that effluxes the bottom that heat exchanger effluxes the middle part after triple valve 15 is divided into two-way, first via cold-producing medium flows to from third connectivity mouth 6 and effluxes top, around arriving interior row top, the top from interior row flows to interior middle and upper part first port of arranging 4 after triple valve 14 flows out after converging the second road cold-producing medium again through first tube connector 3; The second road cold-producing medium flows to the middle and lower part that effluxes from four-way mouth 11, through the 4th tube connector 9 around to interior row middle and lower part, again through the 3rd tube connector 8 around to effluxing the middle and lower part, again from efflux the middle and lower part flow to efflux the middle part, through second tube connector 5 around to interior row middle and upper part, the 7th port of row middle and lower part in flowing to from interior row middle and upper part again, after threeway 14 flow out after converging first via cold-producing medium body.
As shown in Figure 1, former heat exchanger adopts the parallel cross-current flow arrangement of two-way, obviously, efflux air-out after the heat exchange of pipeline will become in the air intake on comb road, so, the heat exchange on interior comb road is seriously undermined, and heat exchange efficiency is on the low side, though by intersect can balanced two-way cold-producing medium heat exchange, but because in the middle of the whole process, the two-way cold-producing medium all is under the heat exchange state of phase mutual interference, and the temperature distributing disproportionation of two-way is even, finally causes whole heat exchange efficiency low; As shown in Figure 2, new heat exchanger adopts the two-way flow process independently to arrange up and down, like this, in heat transfer process, the interference minimum between two-way, two-way respectively is " N " font layout, has also solved the gravity factor problem under the refrigerating state well; Under refrigerating state, heat transfer process is " countercurrent flow ", and under the state of heating, heat transfer process is " following current heat exchange " again, and this has also solved the heat exchange efficiency problem under the different conditions well; Find that by practice test the more original heat exchanger of the heat exchange efficiency of new type heat exchanger improves about 10%.
