Abstract
The invention provides a fin type heat exchanger which comprises a plurality of fin plates, coiled pipes passing through the fin plates, and diversion trenches connected with the lowest points of the lower ends of the fin plates; the horizontal heights of the lower ends of the fin plates are increased gradually; the edges of the lower ends of the fin plates are arranged in an inclining manner; the coiled pipes are spiral or waved bend pipes. The fin type heat exchanger can prevent condensate water from frosting into ice to take bad effects on the heat exchanger, increases the turbulence degree of fluid in the coiled pipe, enhances the heat or cold transfer, and improves the heat transfer effect of the heat exchanger.
Description
Technical field
The present invention relates to the heat exchange field, relate 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.As the untimely condensed water of dredging, will assemble in a large number.Because general spacing of fin is smaller, as the changes in temperature water frosting Cheng Bing of a large amount of gatherings, the distortion that this can cause fin influences service life of A/C evaporator; This can reduce the inned coefficient of evaporimeter in addition, influences refrigeration.In addition, the coiled pipe of utilization of the prior art is mainly bow font bend pipe, influences heat transfer efficiency.
Summary of the invention
The purpose of this invention is to provide finned heat exchanger, solve one or more of existing above-mentioned technical problem.
Technical scheme of the present invention 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.
Heat-exchanger rig provided by the invention 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 frosting of the present invention from becoming the harmful effect of ice heat exchanging device.Another effect of the present invention 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 invention.
In some embodiments, the spacing of fin plate is greater than 2mm.Finned heat exchanger provided by the invention to spacing of fin without limits.
Description of drawings
Fig. 1 is the structural representation of the finned heat exchanger of an embodiment provided by the invention;
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 invention is described in further details.
As shown in Figure 1, the invention 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.
Finned heat exchanger provided by the invention is because the material of heat exchanger fin plate 1 is hydrophilic aluminium foil, so the condensed water that is formed on the heat exchanger fin plate 1 is flowing to heat exchanger fin plate 1 lower end under the meeting rapidly under the gravity effect; 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 heat exchanger fin plate lower end minimum point again rapidly, 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 finned heat exchanger provided by the invention adjacent fins plate 1 spacing without limits, arrange greater than 2mm.
Further, as shown in Figure 1, the finned heat exchanger that the present invention 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.Accompanying drawing of the present invention only illustrates 2 shape of part coiled pipe.
The above only is optimal way of the present invention; should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the invention design; can also make some similar distortion and improvement, these also should be considered as within protection scope of the present invention.
Claims (3)
