Abstract

The utility model relates to a heat exchanger assembly adopting multiple heat exchange fin groups formed by independently expanding tube. Two ends of each heat exchange fin group are respectively connected with a tube plate group, and hairpin tubes of each heat exchange fin group are connected according to refrigerant flow direction. Tube plates of each heat exchange fin group are connected after heat exchanger assembly is bent-formed. This improvement to heat exchanger structure can overcome defects of existing production process, unify specification and size of tube plates, lower difficulty and complication of tube-expanding production process, guarantee completeness of fin and hairpin tube by expanding-before-bending process, and guarantee optimal ventilation effect and passage area among fins. The heat exchanger assembly includes two or more heat exchange fin groups; two ends of each heat exchange fin group are respectively connected with a tube plate group; tube plate groups of each heat exchange fin group are connected with each other via a connector; and hairpin tube ends of each heat exchange fin group are connected with each other.

Description

Heat exchanger assemblies

Technical field

The utility model is a kind of heat exchanger assemblies that is applied to air-conditioner, and this heat exchanger assembly comprises the heat exchange fin group of a plurality of pipe moulding of rising separately particularly.

Background technology

Existing air-conditioner generally adopts pump type heat circulatory system pipeline, and is provided with evaporimeter and the condenser that carries out convection current with circulating air at indoor set and off-premises station one side.The fin that is radial arrangement has constituted the finned tube type main body of heat exchanger.When flowing through heat exchanger, air has bigger area of passage for improving, and for realizing the miniaturization design of air-conditioner complete machine, the combining structures that existing heat exchanger usually adopts many group heat exchange fins to connect, and heat exchanger assemblies carried out to a certain degree bending to reduce to occupy the space as much as possible.

The production technology of existing heat exchanger assemblies is to connect same tube sheet at the same sides of organizing heat exchange fins more, thereby when producing the heat exchanger assembly of different size (row's number is different with length), just needs the tube sheet of different size.Heat exchanger production is risen when pipe, at the heat exchanger assembly of different size, need rise which kind of just is adjusted to pipe expanding machine corresponding size, and operating personnel need conditioning equipment repeatedly, and is time-consuming, require great effort; Different according to row's number, length and the bending angle of many groups heat exchange fin need correspondingly to regulate the quantity and the length of the bar that rises, and more easily cause the distortion of fin or even break and damages, thereby reduce part quality and raise the cost.

The utility model content

Heat exchanger assemblies described in the utility model, its purpose of design is to address the above problem and adopts a plurality of rising separately to manage the heat exchange fin group of moulding, every group of heat exchange fin two ends are connected with one group of tube sheet respectively, move towards to realize that according to refrigerant the hair fastener pipe of respectively organizing heat exchange fin links to each other.Behind the heat exchanger assemblies bending and molding, the tube sheet with each group heat exchange fin interconnects again.Overcome the defective of existing production technology by the improvement of this heat converter structure, both can unify tube sheet specification, reduce the difficulty and the complexity of the pipe production technology that rises, and carry out bending technique at the Guan Houzai that rises, the intact of fin and hair fastener pipe be can guarantee, optimal ventilation effect and area of passage between fin guaranteed.

For realizing above-mentioned purpose of design, the primary structure of described heat exchanger assemblies is:

Have the heat exchange fin group of two groups above (comprising two groups), every group of heat exchange fin two ends are respectively arranged with one group of tube sheet;

Each tube sheet of organizing the heat exchange fin group interconnects by jockey;

According to the trend of refrigerant between many group heat exchange fin groups, each hair fastener pipe end of organizing heat exchange fin interconnects.

As the heat exchanger assemblies of above-mentioned scheme, for the pipe moulding of rising separately of many rows equal length or the different heat exchange fin of length, tube sheet is designed to single tube sheet, no longer needs the tube sheet of plurality of specifications.And, when rising by pipe single fin is separately risen separately, do not need to change the head that rises, the size that only needs to control the pipe that rises gets final product, and need not to regulate repeatedly the tube apparatus that rises.And, even heat exchanger assemblies is carried out bending, can not cause the distortion and the damage of fin and hair fastener pipe yet.

For the heat exchanger assemblies of bending certain angle, between tube sheet concordant after the bending, adopt jockey to interconnect.

Described jockey can adopt " V " shape fixed head to be spirally connected fastening.

Connect when organizing the heat exchange fin group more, can adopt one group of fixed head simultaneously each tube sheet to be connected, also can adjacent tube sheet be connected successively with a plurality of fixed heads.

Content to sum up, the advantage of described heat exchanger assemblies is:

1, described heat exchanger assemblies comprises many group heat exchange fin groups, and single heat exchange fin group is connected, and can heat exchanger assemblies be designed to different shape and setting angle according to designing requirement and arrangement space.

2, the tube sheet of respectively organizing heat exchange fin interconnects respectively, has realized the unification of tube sheet size, thereby reduces the difficulty of the pipe production technology that rises, and effectively guarantees the quality of production of parts and reduces cost.

3, behind the pipe that rises, carry out bending technique, can guarantee the intact of fin and hair fastener pipe, guarantee optimal ventilation effect and area of passage between fin.

The specific embodiment

Embodiment 1, and as shown in Figures 1 to 4, described heat exchanger assemblies has heat exchange fin group 1, heat exchange fin group 2 and heat exchange fin group 3.

Every group of heat exchange fin two ends are respectively arranged with one group of tube sheet 11,21 and 31.

For described heat exchanger assemblies is carried out the bending of certain angle, heat exchange fin group 1, heat exchange fin group 2 has different length with heat exchange fin group 3, and heat exchange fin group 1 is the shortest, and heat exchange fin group 3 is the longest.

Before interconnecting, the pipe moulding of rising separately respectively of heat exchange fin group 1, heat exchange fin group 2 and heat exchange fin group 3;

After with heat exchanger assemblies bending certain angle, adopt one group of " V " shape fixed head 4 and bolt 5 in concordant two side ends, be connected each group tube sheet 11,21 and 31 fastening simultaneously.

According to the trend of refrigerant, each is organized hair fastener pipe 12,22 and 32 and interconnects.
