Abstract
The invention provides an efficient heat exchanger which comprises a plurality of fin plates and a coiled pipe penetrating through the fin plates, wherein horizontal heights of the lower ends of the plurality of fin plates are increased sequentially; the edges of the lower ends of the fin plates are arranged obliquely; spacing between every two adjacent fin plates is smaller than 2 mm; and the coiled pipe is a spiral or corrugated pipe. The efficient heat exchanger provided by the invention can prevent the harmful effect on the heat exchanger effectively due to the fact that condensate water on the fin plates is frosted and frozen, and the efficient heat exchanger has the other effect that the turbulence degree of a fluid in the coiled pipe is increased, the transmission of heat capacity or cooling capacity is enhanced, and the heat transfer effect of the heat exchanger is improved.
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 the fin plate type heat exchanger as heat exchanger, and indoor damp-heat air is through the cooling of fin plate type heat exchanger, in the air steam catch a cold reach capacity and condensation after, condensed water can generate on the plate wing of the evaporimeter of air-conditioning.As the untimely condensed water of dredging, will assemble in a large number.Because general plate wing gap ratio is less, as the changes in temperature water frosting Cheng Bing of a large amount of gatherings, the distortion that this can cause the plate wing 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 high-performance heat exchanger, solve one or more of existing above-mentioned technical problem.
Technical scheme of the present invention 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.
Heat-exchanger rig provided by the invention utilizes the effect of gravity to 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 a hydrophilic aluminium foil, further improves water conservancy diversion effect of the present invention.
Description of drawings
Fig. 1 is the structural representation of the high-performance heat exchanger of an embodiment provided by the invention;
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 invention is described in further details.
As shown in Figure 1, the invention 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.Accompanying drawing of the present invention only illustrates 2 shape of part coiled pipe.
High-performance heat exchanger provided by the invention is because the material of heat exchanger fin plate 1 is a 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, and 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 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 degree shifting to adjacent lower part heat exchanger fin plate 1 lower end, effect is one by one 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 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.
The above only is an 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.
