Abstract

An oblique-inserting type parallel-flow heat exchanger comprises flat tubes, fins, a left collecting main, a right collecting main, end covers, partition plates, a refrigerant inflow pipe and a refrigerant outflow pipe, wherein the refrigerant inflow pipe and the refrigerant outflow pipe are respectively communicated with the left collecting main and the right collecting main, or communicated with only one of the left collecting main and the right collecting main; the partition plates are or are not arranged in the left collecting main and the right collecting main which are respectively communicated with the refrigerant inflow pipe and the refrigerant outflow pipe; and one partition plate is arranged in the collecting main communicated with both the refrigerant inflow pipe and the refrigerant outflow pipe. The oblique-inserting type parallel-flow heat exchanger is characterized in that the flat tubes are parallelly inserted in the left collecting main and the right collecting main in an oblique direction and parallelly communicated with the left collecting main and the right collecting main, and the number of degrees of an included angle beta formed between the plane of the flat tubes and the axis of the collecting mains is within a range of 75-90. Compared with the prior art, air flowing through the flat tubes and the fins is smooth and low in windage resistance, the heat transfer area of the flat tubes and the heat transfer area of the fins can also be increased, and therefore the heat exchange efficiency and the heat exchange volume of the heat exchanger can be significantly improved.

Description

The angle-inserting type parallel flow heat exchanger

Technical field

The utility model belongs to the accessory of air-conditioner, is specifically related to a kind of heat exchanger of air-conditioner.

Background technology

In the prior art, the heat exchanger of air-conditioner is used flat tube plane and the rectangular horizontal parallel regenerative heat exchanger of header axis usually; But this horizontal parallel regenerative heat exchanger, find in actual use, often make the air stream circulation of flow through flat tube and fin not smooth, can cause windage to increase, the flat tube of horizontal positioned makes heat transfer area limited simultaneously, thereby reduces heat exchanger effectiveness and the heat exchange amount of heat exchanger.

Summary of the invention

In view of the foregoing defects the prior art has, intend the heat exchanger of existing air-conditioner is improved, manufacture and design a kind of angle-inserting type parallel flow heat exchanger, thereby improve heat exchanger effectiveness and the heat exchange amount of heat exchanger.

The skill scheme that the Bian of the utility model institute gets is as follows.

A kind of angle-inserting type parallel flow heat exchanger, comprise flat tube, fin, left header, right header, end cap, dividing plate, cold-producing medium inflow pipe and cold-producing medium effuser, fin is uniform to be welded on flat tube, the Two end end cap seal of the Two end of left header and right header; Cold-producing medium inflow pipe and cold-producing medium effuser are communicated with left header and right header respectively, perhaps all are communicated with therein on a header; According to the cold-producing medium requirements of process, arrange or do not arrange dividing plate in the left header that is communicated with respectively with cold-producing medium inflow pipe and cold-producing medium effuser and right header; With header that cold-producing medium inflow pipe and cold-producing medium effuser all are communicated with in dividing plate is set; It is characterized in that:

In the flat tube left header of parallel oblique insertion and right header, and the left header of parallel connection and right header, the Zhou Xian Clip angle β of the plane of flat tube and header spends to 90 degree scopes 75.

The angle-inserting type parallel flow heat exchanger of the utility model structure, compare with existing horizontal parallel regenerative heat exchanger, the air of flat tube and fin of flowing through is smooth, has lower windage, can increase the heat transfer area of flat tube and fin again, thereby can significantly improve heat exchanger effectiveness and the heat exchange amount of heat exchanger, in addition, it also has drainage performance preferably.

Specific embodiments

Further illustrate concrete structure of the present utility model and cold-producing medium flow process trend below in conjunction with accompanying drawing.Need to prove, the utility model angle-inserting type parallel flow heat exchanger never is confined to example.

A kind of angle-inserting type parallel flow heat exchanger, comprise flat tube 6, fin 5, left header 2, right header 7, end cap 1, dividing plate 3, cold-producing medium inflow pipe 4 and cold-producing medium effuser 8, fin 5 is uniform to be welded on flat tube 6, and the Two end of the Two of left header 2 end and right header 7 seals with end cap 1; Cold-producing medium inflow pipe 4 and cold-producing medium effuser 8 are communicated with (see figure 1) with left header 2 and right header 7 respectively, perhaps all are communicated with therein (see figure 2) on right header 7; In the left header 2 that is communicated with respectively with cold-producing medium inflow pipe 4 and cold-producing medium effuser 8 and right header 7, dividing plate 3(is set and sees Fig. 1); With right header 7 that cold-producing medium inflow pipe 4 and cold-producing medium effuser 8 all are communicated with in dividing plate 3(be set see Fig. 2); It is characterized in that: in the left header 2 of the parallel oblique insertion of flat tube 6 and right header 7, and the left header 2 of parallel connection and right header 7, the Zhou Xian Clip angle β of the plane of flat tube 6 and header spends to 90 degree scopes 75.

In angle-inserting type parallel flow heat exchanger of the present utility model, as shown in Fig. 1 example, cold-producing medium flows to left header 2 from cold-producing medium inflow pipe 4, turn back in 3 places at dividing plate, and the 6 right headers 7 of inflow of the flat tube more than 3 collect along dividing plate, then the flat tube 6 of dividing plate more than 3 along right header 7 flows into left header 2 and collects, then collects along the flat tube 6 right headers 7 of inflow of dividing plate below 3 of right header 7, flows out from cold-producing medium effuser 8 at last; As shown in Fig. 2 example, cold-producing medium flows to the top of right header 7 from cold-producing medium inflow pipe 4, turn back in 3 places at dividing plate, and the flat tube more than 36 flows into left header 2 and collects along dividing plate, then the bottom that the flat tube below 36 flows into right header 7 along dividing plate is collected, and flows out from cold-producing medium effuser 8 at last.
