Abstract

The invention relates to a heat exchanger. The heat exchanger comprises a cylinder body, a cavity is formed in the cylinder body, the cylinder body is provided with a cylinder body inlet and a cylinder body outlet, a plurality of winding branch pipes are accommodated in the cavity, each winding branch pipe is formed by pipe enwinding, a plurality turns of ring-shaped structures are formed roughlyby the pipe enwinding on a same plane, and the multiple winding branch pipes are arranged at a preset distance at intervals in the vertical direction. First openings and second openings are separatelyformed at both ends of each winding branch pipe, each first opening communicates with a first main pipeline, and each second opening communicates with a second main pipeline. Through the superposition setting of a plurality of involute branch pipes, the heat transfer area can be obviously increased, and the heat transfer efficiency is improved.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to an involute tube heat exchanger for a cold trap machine. Background technique [0002] At present, the fin drying process of the two devices (condenser and evaporator, also known as indoor heat exchanger and outdoor heat exchanger) in the air-conditioning industry generally uses natural gas to degrease the heat exchanger at high temperature, generating a large amount of heat (atmospheric pressure The lower temperature reaches 160-180°C). The heat exchanger contains a large amount of copper tube oil and fin oil, which will generate a large amount of oil mist (mainly containing C12-C16 saturated alkanes) during the high-temperature drying process, and at the same time, the high-temperature degreasing process will also generate a large amount of exhaust gas ( It mainly contains triphenyl, styrene, total VOCs, non-methane total hydrocarbons, nitrogen dioxide, nitrogen oxides, carbon monoxide, smo...
