Abstract

The utility model provides a high-efficiency heat exchanger. The high-efficiency heat exchanger comprises a plurality of fin plates and a serpentine pipe penetrating through the fin plates, wherein the horizontal heights of the lower ends of the fin plates are gradually increased; the edges of the lower ends of the fin plates are arranged in an inclined manner; the distance between adjacent fin plates is smaller than 2 mm; and the serpentine pipe is a spiral or wavy bent pipe. The high-efficiency heat exchanger can effectively prevent condenser water on the fin plates from being frosted and iced to cause bad influence on the heat exchanger. The high-efficiency heat exchanger has other effects of increasing degree of turbulent flow of fluid inside the serpentine pipe, strengthening the transportation of heat quantity or cold quantity and improving the heat exchange effect of the heat exchanger.

Description

High-performance 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 the fin plate heat exchanger as heat exchanger, and indoor damp-heat air is through the cooling of fin plate heat exchanger, in the air steam catch a cold reach capacity and condensation after, condensed water can generate at the plate wing of the evaporimeter of air-conditioning.Such as the untimely condensed water of dredging, will assemble in a large number.Because general plate wing spacing is smaller, as the cold-warm water frosting Cheng Bing of a large amount of gatherings, the distortion that this can cause the plate wing 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 high-performance heat exchanger, solves one or more of existing above-mentioned technical problem.

The technical solution of the utility model provides a kind of high-performance heat exchanger, comprise a plurality of fin plates and the coiled pipe that navigates within 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, the spacing of adjacent fins plate is less than 2mm, 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.

Description of drawings

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

Fig. 2 is that the A of high-performance 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 high-performance heat exchanger, comprise a plurality of fin plates 1 and the coiled pipe 2 that navigates within 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, the spacing of adjacent heat exchanger fin plate 1 is less than 2mm, and coiled pipe 2 is helical form or wavy bend pipe.The utility model accompanying drawing only illustrates the shape of part coiled pipe 2.

The high-performance 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, and 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 along with the extension pearl that formation is magnified gradually of increasing of condensed water; Spacing less than the 2mm situation under, hang pearl and magnify to a certain extent and can shift to adjacent lower part heat exchanger fin plate 1 lower end, one by one effect is concentrated condensed water in heat exchanger fin plate 1 lower end of lowest part, finish condensate water guide work.

Further, as shown in Figure 1, the high-performance 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 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.
