Problems solved by technology

[0003] The shells of existing heat exchangers are mostly made of metal, resulting in heavy heat exchangers and inconvenient installation and use; at the same time, due to inconsistent customer needs, heat exchangers need to redesign a set of molds according to each specific customer, resulting in The production cost of the heat exchanger is high; in addition, the heat exchanger often needs to work under high temperature conditions, and the shell of the heat exchanger is easy to crack due to thermal expansion, and the service life is short

Abstract

The invention discloses a heat exchanger, comprising a shell assembly, an upper end cover, a lower end cover and a heat exchange tube assembly, wherein the shell assembly comprises an upper tube barrel, a middle tube barrel and a lower tube barrel; the heat exchange tube assembly comprises a plurality of heat exchange tubes which are arranged in clusters; and the heat exchange tube are all locatedin a total accommodating cavity. The heat exchanger provided by the invention has the beneficial effects that the shell of the heat exchanger is made of plastic so as to reduce the weight of the heatexchanger; the shell of the heat exchanger is divied into the upper tube barrel, the middle tube barrel and the lower tube barrel engaged with each other end to end, the upper tube barrel and the lower tube barrel are produced into standard components, and the length of the middle tube barrel is determined based on the demand of a user so as to the manufacturing cost of an injection mold; furthermore, the upper tube barrel, the middle tube barrel and the lower tube barrel are connected by engagement and have certain flexible spaces therebetween so as to cancel out the influence of thermal expansion in a high-temperature operating mode, and prolong the service life of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of thermal energy utilization, in particular to a heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, and it plays an important role in chemical, petroleum, power, food and many other industrial productions. [0003] The shells of existing heat exchangers are mostly made of metal, resulting in heavy heat exchangers and inconvenient installation and use; at the same time, due to inconsistent customer needs, heat exchangers need to redesign a set of molds according to each specific customer, resulting in The production cost of the heat exchanger is high; in addition, the heat exchanger often needs to work under high temperature conditions, and the shell of the heat exchanger is easy to crack due to thermal expansion, and the service life is short. Contents of the invention [0004] In view of this, it is necessary to prov...
