Abstract

The utility model provides a heat exchanger. The heat exchanger comprises a plurality of heat exchanger board fins, a coiled pipe and a guiding groove, wherein the coiled pipe penetrates through the heat exchanger board fins, and the guiding groove is used for connecting the lowest points of the lower ends of the heat exchanger board fins. The horizontal height of the lower ends of the heat exchanger board fins gradually becomes larger, and the edges of the lower ends of the heat exchanger board fins are slantly arranged. An improved method on the structure of the heat exchanger board fins is provided, and the heat exchanger is prevented from being affected by frosting and icing.

Description

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 plate-fin heat exchanger as heat exchanger, and indoor damp-heat air is through the cooling of plate-fin 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.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.
The utility model content
The purpose of this utility model provides a kind of plate-fin heat exchanger, solves one or more of existing above-mentioned technical problem.
Technical scheme of the present utility model is: heat exchanger comprises a plurality of heat exchanger plate fins, navigates within the coiled pipe and the guiding gutter that is connected a plurality of heat exchanger plate fin lower ends minimum points of heat exchanger plate fin, the level height of a plurality of heat exchanger plate fin lower ends increases one by one, and heat exchanger plate fin lower ends edge tilt arranges.
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 plate fin structure is provided, and prevents that the utility model frosting from becoming the harmful effect of ice heat exchanging device.
In some embodiments, the material of heat exchanger plate fin is hydrophilic aluminium foil, further improves water conservancy diversion effect of the present utility model.
In some embodiments, the spacing of adjacent heat exchanger plate fin is greater than 2mm.The utility model is suitable equally greater than the situation of 2mm for the spacing of heat exchanger plate fin.
Description of drawings
The structural representation of the heat exchanger of a kind of embodiment that Fig. 1 provides for the utility model;
Fig. 2 is that the A of 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 heat exchanger, comprises a plurality of heat exchanger plate fins 1, navigates within the coiled pipe 2 and the guiding gutter 3 that is connected a plurality of heat exchanger plate fin 1 lower end minimum points of heat exchanger plate fin 1.As shown in Figure 2, the level height of a plurality of heat exchanger plate fins 1 lower end increases one by one, and heat exchanger plate fin 1 lower edge is obliquely installed, and the spacing of adjacent heat exchanger plate fin 1 is greater than 2mm.The material of heat exchanger plate fin 1 is hydrophilic aluminium foil.
The plate-fin heat exchanger that the utility model provides is because the material of heat exchanger plate fin 1 is hydrophilic aluminium foil, so the condensed water that is formed on the heat exchanger plate fin 1 is flowing to heat exchanger plate fin 1 lower end under the meeting rapidly under the gravity effect; Further, as shown in Figure 2, heat exchanger plate fin 1 lower edge is obliquely installed, and can make the condensed water that flow to the lower end be concentrated to heat exchanger plate fin lower ends cloth guiding gutter 3 places again rapidly; Spacing greater than the 2mm situation under because the level height of heat exchanger plate fin 1 lower end increases one by one, condensed water can be concentrated to heat exchanger plate fin 1 lower end of lowest part along guiding gutter 3, finishes condensate water guide work.
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.
