Abstract

The utility model provides a fin type heat exchanger, which comprises a plurality of fins, serpentine tubes and a gutter, the serpentine tubes wind through the fins, the gutter is connected with the lowest points of the lower ends of the fins, the levels of the lower ends of the fins are increased one by one, the lower ends of the fins are sloped, and the serpentine tubes are helical or wavy curved tubes. The utility model can prevent the adverse affection of condensate frosting into ice on the heat exchanger, moreover, the degree of turbulence of fluid in the serpentine tubes is increased, the transfer of heat or cold is enhanced, and the heat transfer effect of the heat exchanger is enhanced.

Description

Finned heat exchanger

Technical field

The utility model relates to the heat exchange field, relates in particular to the heat exchanger in the air-conditioning manufacturing.

Background technology

A/C evaporator generally uses finned heat exchanger as heat exchanger, and indoor damp-heat air is through the cooling of finned heat exchanger, in the air steam catch a cold reach capacity and condensation after, condensed water can generate at the fin of the evaporimeter of air-conditioning.Such as the untimely condensed water of dredging, will assemble in a large number.Because general spacing of fin is smaller, as the cold-warm water frosting Cheng Bing of a large amount of gatherings, the distortion that this can cause fin affects service life of A/C evaporator; This can reduce the inned coefficient of evaporimeter in addition, affects refrigeration.In addition, the coiled pipe of utilization of the prior art is mainly bow font bend pipe, affects heat transfer efficiency.

The utility model content

The purpose of this utility model provides finned heat exchanger, solves one or more of existing above-mentioned technical problem.

The technical solution of the utility model provides a kind of finned heat exchanger, comprise a plurality of fin plates, navigate within the coiled pipe and the guiding gutter that is connected a plurality of fin plates lower end minimum point of fin plate, the level height of a plurality of fin plates lower end increases one by one, the fin plate lower edge is obliquely installed, and coiled pipe is helical form or wavy bend pipe.

The heat-exchanger rig that the utility model provides utilizes gravity to the effect of condensed water, and a kind of mode that improves on the heat exchanger fin plate structure is provided, and prevents that the utility model frosting from becoming the harmful effect of ice heat exchanger.Another effect of the present utility model is the turbulent extent that has increased the coiled pipe inner fluid, has strengthened the transmission of heat or cold, has improved the heat-transfer effect of heat exchanger.

In some embodiments, the material of fin plate is hydrophilic aluminium foil, further improves water conservancy diversion effect of the present utility model.

In some embodiments, the spacing of fin plate is greater than 2mm.The finned heat exchanger that the utility model provides is to not restriction of spacing of fin.

Description of drawings

The structural representation of the finned heat exchanger of the embodiment that Fig. 1 provides for the utility model;

Fig. 2 is that the A of finned heat exchanger shown in Figure 1 is to view.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is described in further details.

As shown in Figure 1, the utility model provides a kind of finned heat exchanger, comprise a plurality of fin plates 1, navigate within the coiled pipe 2 and the guiding gutter 3 that is connected a plurality of fin plate 1 lower end minimum points of fin plate 1, the level height of a plurality of fin plates 1 lower end increases one by one, fin plate 1 lower edge is obliquely installed, and coiled pipe 2 is helical form or wavy bend pipe.

The finned heat exchanger that the utility model provides is because the material of heat exchanger fin plate 1 is hydrophilic aluminium foil, therefore the condensed water that is formed on the heat exchanger fin plate 1 can be rapidly downstream to heat exchanger fin plate 1 lower end under Action of Gravity Field; Further, as shown in Figure 2, heat exchanger fin plate 1 lower edge is obliquely installed, can make the condensed water that flow to the lower end be concentrated to rapidly again heat exchanger fin plate lower end minimum point, and under the guide functions of guiding gutter 3, shift to adjacent lower part heat exchanger fin plate 1 lower end, shift one by one, condensed water is concentrated in heat exchanger fin plate 1 lower end of lowest part, finish condensate water guide work.

It is pointed out that the not restriction of spacing of the adjacent fins plate 1 of the finned heat exchanger that the utility model provides, arrange greater than 2mm.

Further, as shown in Figure 1, the finned heat exchanger that the utility model improves because coiled pipe 2 adopts helical form or wavy bend pipe, can improve coiled pipe internal flow turbulent extent greatly, improves heat-transfer effect.The utility model accompanying drawing only illustrate part coiled pipe 2 shape.

The above only is optimal way of the present utility model; should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the utility model creation design; can also make some similar distortion and improvement, these also should be considered as within the protection domain of the present utility model.
