Abstract
The invention discloses a fin of an air-conditioner evaporator. The fin is provided with two lists of mounting holes for mounting U-shaped radiating pipes respectively, and a plurality of longitudinal strip notches arranged along a straight line are formed between the two lists of mounting holes. The middle of the fin between the two lists of inner and outer U-shaped radiating pipes of the air-conditioner evaporator is cut and separated so as to avoid direct heat transfer between the fins and affect the dehumidification effect; and the method is simple and reliable, and achieves good constanttemperature dehumidification effect without increasing the product cost. The invention also provides the air-conditioner evaporator using the fin.
Description
Technical field
The present invention relates to air-conditioning, be specifically related to A/C evaporator and fin.
Background technology
Air-conditioning has been widely used in family and office space, for people provide comfortable work and living environment.The raising of Along with people's quality of the life, existing air-conditioning major part all possesses constant-temperature dehumidifying function.Wherein, evaporimeter is one of critical piece of air-conditioning realization heat exchange, and as shown in Figure 1, existing A/C evaporator generally is made up of inside and outside two row U-shaped radiating tubes 21,22, and the inside and outside row U-shaped radiating tube 21,22 of two row connects as one through fin 23 respectively.When air-conditioning carried out constant temperature dehumidification, A/C evaporator outer classified refrigeration 21 as, in classify as and heat 22; Because the fin of existing evaporimeter is structure as a whole, therefore, inside and outside row U-shaped radiating tube 21, can be between 22 through fin 23 direct heat transfers; Influence the effect of constant temperature dehumidification, increase the constant temperature dehumidification amount, certainly will need to increase the area of evaporimeter like need; Under the overall situation that the copper valency goes up day by day, product cost is increased greatly, and also be a kind of very big waste the resource of country.
Summary of the invention
Technical problem to be solved by this invention is to solve the relatively poor problem of A/C evaporator constant temperature dehumidification effect.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted provides a kind of fin of A/C evaporator; Which is provided with two row and be respectively applied for the installing hole that the U-shaped radiating tube is installed, be provided with some vertical bar shaped otch of arranging along straight line between the said two row installing holes.
In the fin of above-mentioned A/C evaporator, said bar shaped otch is drawing, and a side has flange.
In the fin of above-mentioned A/C evaporator, said bar shaped otch is drawing, and both sides have flange respectively.
In the fin of above-mentioned A/C evaporator, two said flange are parallel to each other or two said flange difference semicirculars in shape.
In the fin of above-mentioned A/C evaporator, the quantity of said bar shaped otch is one.
The present invention also provides a kind of A/C evaporator; Row U-shaped radiating tube and outer row U-shaped radiating tube in comprising; Row U-shaped radiating tube is fixedly connected through the fin that some intervals are provided with outer row U-shaped radiating tube in said; Said fin is provided with some vertical bar shaped otch of arranging along straight line, and said bar shaped otch is between inside and outside row U-shaped radiating tube.
In above-mentioned A/C evaporator, said bar shaped otch is drawing, and a side has flange.
In above-mentioned A/C evaporator, said bar shaped otch is drawing, and both sides have flange respectively.
In above-mentioned A/C evaporator, two said flange are parallel to each other or two said flange difference semicirculars in shape.
In above-mentioned A/C evaporator, the quantity of said bar shaped otch is one.
The present invention; Carry out cutting and separating in the middle of the fin between the inside and outside two row U-shaped radiating tubes of A/C evaporator, avoid direct heat transfer between the fin, influence effect on moisture extraction; Method is simple and reliable, under the situation that does not increase product cost, has obtained good constant temperature dehumidification effect.
