Abstract
A heat exchanger of an air conditioner comprises a left collecting pipe, a right collecting pipe and a heat exchanging unit, wherein the heat exchanging unit is arranged between the left collecting pipe and the right collecting pipe. The heat exchanging unit is composed of a flat pipe and fins, a left end of the flat pipe is axially connected with the left collecting pipe, a right end of the flat pipe is axially connected with the right collecting pipe, the flat pipe is radially inclined, and two ends of the flat pipe in the radial direction are positioned out of the same horizontal line. Due to the fact that the flat pipe of the heat exchanger of the air conditioner is radially inclined, condensed water on the flat pipe can flow downwards along the radial inclined plane of the flat pipe, water self-discharging of the heat exchanger of the air conditioner is realized, the problems of icing and frosting of concurrent flow fins caused by poor water discharging effect of an existing concurrent flow heat exchanger are solved, and the concurrent flow heat exchanging rate is improved.
Description
Technical field
The utility model relates to air-conditioner parts technical field, more particularly, relates to a kind of air-condition heat exchanger.
Background technology
Along with improving constantly of living standards of the people, air-conditioner has entered huge numbers of families, and air-conditioning technical just towards energy-conservation, direction develops efficiently.Heat exchanger is as one of vitals in the air-conditioning system, and its heat exchange effect can directly influence the performance of whole system, and its weight and volume size also can influence the compactedness and the volume of complete machine.For the heat exchange efficiency that improves air-condition heat exchanger, reduce its installation footprint, its version is now from fin tube type, the stacked parallel flow type that develops into.Fin-tube heat exchanger is the heat exchanger structure that uses the earliest, and stacked heat exchanger is that a kind of runner is the plate type heat exchanger of U-shaped, its compact conformation, the heat exchange efficiency height, but difficulty of processing is bigger, and owing to be subjected to the restriction of appearance and size, it can not satisfy the condition of big heat exchange amount.Parallel-flow heat exchanger is a kind of novel flat pipe heat exchanger that grows up on the basis of fin tube type, stacked heat exchanger at present, and it has been considered to a kind of regeneration product of the most rising air-condition heat exchanger with efficient, compact characteristics.As Fig. 1, Fig. 2, shown in Figure 5, the flat tube of existing parallel-flow heat exchanger all adopts horizontally disposed mode, when the air conditioner heat-production mode operation, when the temperature of parallel-flow heat exchanger was lower than environment temperature, the condensed water that airborne moisture content condensation is produced was attached to discharging on the flat tube of parallel-flow heat exchanger.Also may appear at air-conditioner running time frosting or icing phenomenon on the flat tube of concurrent flow when longer, cause the thermal conversion rate of air-conditioning system low, the heat exchange effect further worsens.
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, air-condition heat exchanger that heating effect is good are provided.
The technical solution adopted in the utility model is, a kind of air-condition 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, the axial left end of described flat tube connects left header, the axial right-hand member of described flat tube connects right header, described flat tube radial skew, and the radially two ends of described flat tube are not on same horizontal line.
Above-mentioned air-condition heat exchanger, the radial skew angle of described flat tube is in 10～80 degree scopes.
Above-mentioned air-condition heat exchanger, the radial skew angle of described flat tube are 13～40 degree.
Above-mentioned air-condition heat exchanger describedly is located at flat tube arrangement parallel to each other between left header and right header.
Above-mentioned air-condition 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 radial skew of air-condition heat exchanger of the present utility model, condensed water on the flat tube is flowed down along the radial of flat tube, realized the self-drain function of air-condition heat exchanger, solved that concurrent flow fin that present 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 air-condition heat exchanger produces, flow to a side at gravity, make the air-condition heat exchanger heating effect better.
2) the assembly technology maturation of the heat exchange unit of air-condition heat exchanger and left and right sides header in the wooden utility model, flat tube has improved production efficiency greatly being assemblied in after the inclination 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. 4, Fig. 6, the utility model provides a kind of air-condition heat exchanger, the field that belongs to air-condition heat exchanger, constitute by left header 3, right header 4, flat tube 1 and fin 2, flat tube 1 axial level connects left header 3 and right header 4, the radial skew of flat tube 1 makes moisture content on the heat exchanger can flow to the other end of low level along flat tube 1 end radially.Flat tube 1 radially be the inclination angle of flat tube 1 with horizontal angle, its span be 10～80 the degree, optimal value be 13～40 the degree.All flat tube 1 arrangements parallel to each other of air-condition heat exchanger, flat tube 1 is the porous flat pipe structure, referring to Fig. 7, 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 air-condition heat exchanger.
The fin structure of the utility model air-condition heat exchanger can adopt dull and stereotyped slice structure as shown in Figure 1, also can select wave fin structure as shown in Figure 7.
The course of work of cold-producing medium in air-condition heat exchanger is: under the air conditioner heat-production pattern, cold-producing medium flows in the multiple tracks coolant channel 14 of flat tube 1, and the convection current air is along flat tube 1 flows outside.The cold-producing medium that comes out from the throttling arrangement of air-conditioning system enters from the influent stream chamber of inlet tube through left header 3 (or right header 4), in the multiple tracks coolant channel 14 of flat tube, flow, enter right header 4 (or left header 3) then, leave air-condition heat exchanger from outlet.Flat tube 1 inner refrigerant is along with being overheated gas by liquid, two-phase state-transition gradually with the carrying out of the outer convection current air heat transfer process of pipe, and last overheated gaseous refrigerant is got back in the compressor of air conditioner.
