The utility model content
The utility model purpose is in order to overcome the deficiency that above-mentioned prior art exists, and a kind of thermal conversion rate height, parallel-flow heat exchanger that heating effect is good are provided.
The technical solution adopted in the utility model is, a kind of parallel-flow heat exchanger, comprise left header, right header, be located at the heat exchange unit between left header and right header, described heat exchange unit is made of flat tube and fin, one end of described flat tube connects left header, and the other end of described flat tube connects right header, and described flat tube is made of left side pipe and right side pipe, described left side pipe is with in the left header of the downward-sloping insertion of angle A, and described right side pipe is with in the right header of the downward-sloping insertion of angle B.
Above-mentioned parallel-flow heat exchanger, angle A equates with angle B numerical value.
Above-mentioned parallel-flow heat exchanger, angle A is in 10～80 degree scopes.
Above-mentioned parallel-flow heat exchanger, arrangement parallel to each other is managed in the left side of described flat tube, and arrangement parallel to each other is managed on the right side of described flat tube.
Above-mentioned parallel-flow heat exchanger, described left side pipe is provided with gutter channel in the end near left header, and described right side pipe is provided with gutter channel in the end near right header.
Above-mentioned parallel-flow heat exchanger is provided with the above coolant channel of twice or twice in the described flat tube.
Compared with prior art, the utlity model has following advantage:
1) because the flat tube of parallel-flow heat exchanger of the present utility model is divided into azimuth by-pass, azimuth by-pass is oblique connection left and right sides header respectively, condensed water on the flat tube is flowed down along the inclined-plane of flat tube, realized the self-drain function of parallel-flow heat exchanger, solved that concurrent flow fin that parallel-flow heat exchanger draining difficulty causes freezes and the problem of frosting, improved the parallel flow heat conversion ratio, when air-conditioning system is moved with heating mode, under the effect of water that parallel-flow heat exchanger produces, flow to both sides, make the parallel-flow heat exchanger heating effect better at gravity.
2) utilize the heat exchange unit of existing parallel-flow heat exchanger and the ripe assembly technology of left and right sides header in the wooden utility model, flat tube has improved production efficiency greatly being assemblied in behind the bending forming on the header of the left and right sides; Flat tube is a loose structure, has a plurality of coolant channels, and the gaseous refrigerant that produces in heat transfer process is in time drained in the header, and the flat tube heat exchange area of whole heat exchange unit is utilized more fully, thereby has further improved heat exchange efficiency.

The specific embodiment
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Referring to Fig. 3, Fig. 5, Fig. 6, Fig. 7, the utility model provides a kind of parallel-flow heat exchanger, constitute by left header 3, right header 4, flat tube 1 and fin 2, the end of the left side pipe 11 of flat tube 1 connects left header 3, the end of the right side pipe 12 of flat tube 1 connects right header 4, the azimuth by-pass of flat tube 1 tilts to the header of both sides respectively, makes the moisture content on the heat exchanger can flow to both sides.Wherein, left side pipe 11 is with the left header 3 of downward-sloping insertion, and the right side manages 12 with the right header 4 of the downward-sloping insertion of angle B, and as shown in Figure 6, angle A is the angle of left side pipe 11 and horizontal plane, and angle B is the angle of right side pipe 12 and horizontal plane, and A=B.It is 10～80 degree that angle A, angle B have span.All left side pipe 11 arrangements parallel to each other of parallel-flow heat exchanger, all right side pipe 12 arrangements also parallel to each other.In order to make the smooth outflow heat exchanger of water, be provided with gutter channel near the end of left header 3 and right header 4 respectively at left side pipe 11, right side pipe 12.See Fig. 7, the flat tube 1 of parallel-flow heat exchanger of the present utility model is the porous flat pipe structure, is provided with the coolant channel 14 of multiple tracks in the flat tube 1.Make that the heat exchange area of flat tube 1 is utilized more fully, thereby further improve the exchange capability of heat of parallel-flow heat exchanger.
