Abstract
A heat exchanger of an air conditioning belongs to the technical field of air conditioning which is designed for improving the heat exchange efficiency. The utility model includes a shell 1 with an inlet and an outlet; a fair water fin 2 is arranged in the shell 1; a tube beam ( not displayed in the drawing) penetrates the fair water fin 2 and is arranged in the shell; the inlet and the outlet of the tube beam are communicated to the outside of the shell 1; the utility model is characterized in that the fair water fin 2 is spiral and the outer edge 29 of the fair water fin 2 is close to the inner wall of the shell 1; the fair water fin 2 consists of a plurality of same parts. The part includes a basic tube 20; the spiral fair water fin 2 extends on the basic tube 20; the length of the basic tube 20 is three fourth of the thread pitch of the spiral fair water fin 2; besides the fourth of the thread pitch, the outer diameter of one end of the basic tube 20 shortens to form a stopper plug 201 and steps form between the stopper plug 201 and the basic tube 20; a through hole 25 is arranged on the spiral fair water fin 2; copper tubes forming the tube beam just penetrate in the through hole 25.
Description
Affiliated technical field
The utility model belongs to air-conditioning technical field.Relate in particular to heat exchanger.
Background technology
Existing a kind of air-condition heat exchanger that is called as shell-and-tube heat exchanger, its structure are to lay tube bank in a housing, circulation cycle fluid to be cooled in restraining, the interior circulation cycle water of housing that tube bank is outer.For time of contact of increasing recirculated water and tube bank improving heat exchange efficiency, general in housing, interlace at interval be laid with arc deflector.But, its final recirculated water fluidised form that forms, it is the stagnant area that the zone of 20%-40% is arranged in shell approximately, makes heat exchange efficiency still not ideal enough.
Summary of the invention
In order to improve heat exchange efficiency, the utility model provides a kind of air-conditioning heat exchanger.
The technical solution of the utility model is: substitute the arc deflector in the housing of being laid in that interlaces at interval with spiral deflector.That is:
A kind of air-condition heat exchanger comprises a housing that (recirculated water) import and outlet are arranged, and deflector is arranged in the housing, has tube bank to penetrate deflector and is laid in the housing, and the import of tube bank and outlet are communicated to outside the housing; It is characterized in that: said deflector is a spirality, and the outer rim of deflector is pressed close to the inwall of housing.
The beneficial effects of the utility model: by above-mentioned structure as can be known, the utility model has been eliminated the stagnant area of recirculated water, thereby has higher heat exchange efficiency.After testing, its whole coefficient of heat transfer has improved 30%.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a decomposing schematic representation of the present utility model.Be illustrative simplicity, wherein not shown tube bank, flange and end cap.
Fig. 2 is the part drawing of deflector.
The specific embodiment
As shown in the figure, a kind of air-condition heat exchanger comprises a housing 1 that import and outlet are arranged, and deflector 2 is arranged in the housing 1, has the tube bank (not shown) to penetrate deflector 2 and is laid in the housing, and the import of tube bank and outlet are communicated to outside the housing 1; It is characterized in that: said deflector 2 is spiralitys, and the outer rim 29 of deflector is pressed close to the inwall of housing 1.
As shown in the figure, the main body of housing 1 is one section pipe.Not shown: there is flange at the two ends of pipe and connects end cap, and (recirculated water) import and outlet are arranged on the end cap.These belong to existing known technology.
(cycle fluid) import and the outlet of tube bank are communicated to outside the housing 1.Its particular location can be at end cap, also can be in the pipe portion of housing 1.It also is existing known technology.
As shown in the figure, deflector 2 is combined by the identical part that several (being illustrated as 2) are illustrated in Fig. 2.This part comprises a parent tube 20, extends spiral guiding plate 2 (part) on the parent tube 20, and the length of parent tube 20 is 3/4 pitch of spiral guiding plate 2; Outside 3/4 pitch, its reduced diameter of an end of parent tube 20 forms chock plug 201, and forms step between 20 ones of chock plug 201 and the parent tubes; Be distributed with through hole 25 on the spiral guiding plate 2, the copper pipe of forming tube bank just penetrates in through hole 25.This part is suitable for injection molded.Such part chock plug 201 one by one is enclosed within the parent tube 20, and the lower edge 28 of their spiral guiding plates overlap one by one with upper limb 22, promptly constitutes (integral body) spiral guiding plate 2 to needed length.
