Embodiment 1 2

[0030] like Figure 1 to Figure 5 As shown in , Embodiments 1 and 2 of the present invention provide a plastic heat exchanger, which includes an outer shell 1 and a plastic heat exchange core 2 arranged in the outer shell 1. The plastic heat exchange core 2 includes parallel stacked A plurality of heat exchange fins 21, the plurality of heat exchange fins 21 are all formed by hot pressing of plastic materials, and are sealed and fixed to each other by heat sealing to form a heat exchange air duct. The specific structure can be as follows: figure 2 , 3 and 4, one side surface of the heat exchange fin 21 is provided with several parallel raised main ribs 23, and the main ribs 23 are provided with several raised positioning parts 24; the other side surface of the heat exchange fin 21 There are fixing slots 25 that match the protruding positioning parts 24 of the adjacent heat exchanging fins 21, and the one side surface of the heat exchanging fins 21 is provided with positioni...

Embodiment 3 4

[0034] like Figure 6 to Figure 8 As shown in , Embodiments 3 and 4 of the present invention provide a plastic heat exchanger, the structure of which is basically the same as that of Embodiments 1 and 2, including an outer shell 1 and a plastic heat exchange core 2 disposed in the outer shell 1, said The plastic heat exchanging core 2 includes a plurality of heat exchanging fins 21 stacked in parallel. The plurality of heat exchanging fins 21 are formed by hot pressing of plastic materials, and are sealed and fixed to each other by heat sealing to form an exchanging structure. The hot air passage; and the surface of the heat exchange fins 21 located in the heat exchange air passage between two adjacent heat exchange fins 21 is provided with a heat exchange enhancement surface 22 . The only difference is that the plurality of heat exchanging fins 21 includes a plurality of heat exchanging fin groups composed of first heat exchanging fins 21A and second heat exchanging fins 21B ...

Abstract

The invention relates to a plastic heat exchanger which comprises a shell and a plastic heat exchange core arranged in the shell, wherein the plastic heat exchange core comprises multiple heat exchange sheets stacked in parallel; the multiple heat exchange sheets are formed by thermally pressing plastic materials, and are mutually sealed and fixed through a thermal sealing mode to form heat exchange air ducts. Therefore, the stability and the reliability of the heat exchange core sealing and fixing effect can be obviously improved, and the heat exchange performance is higher; the problem that the conventional metal heat exchange cores adopting a glue sealing mode easily leak glue is solved; furthermore, the plastic heat exchanger is light in weight, low in machining difficulty and cost, high in production efficiency, environmental-friendly and pollution-free, further can effectively reduce the difficulty in machining of a wavy folded surface, is more ideal in heat exchange effect and is more favorable for batch production. Meanwhile, heat exchange enhancing surfaces are arranged on the surfaces, located in the heat exchange air ducts, of the heat exchange sheets, so that the heat exchange area can be effectively enlarged, and the heat exchange capacity of the heat exchanger is further improved; moreover, the thermal pressing machining and molding mode is very simple and easy.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, in particular to a plastic heat exchanger. Background technique [0002] At present, the existing heat exchangers on the market include a shell and a heat exchange core, and the heat exchange core is formed by stacking a number of metal heat exchange sheets, and is sealed and fixed by glue sealing. However, due to the poor stability of the glue sealing method, degumming is prone to occur, resulting in leakage, which affects the heat exchange performance. At the same time, the heat exchange core composed of metal heat exchange fins is not only heavy, but also difficult to process. , low production efficiency, high cost, and also pollute the environment and are not environmentally friendly. Contents of the invention [0003] In order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a method that can improve the stability an...
