Heat exchanger with 2-20 flow paths

Abstract

The invention provides a heat exchanger with 2-20 flow paths. The heat exchanger with the 2-20 flow paths comprises 1-20 heat exchanger bodies. The heat exchanger with the 2-20 flow paths is characterized in that by the adoption of a method for increasing the number of the flow paths, the total length of a first medium flow channel and the total length of a second medium flow channel of the heat exchanger are increased, the total length of the first medium flow channel is made to reach 0.3-20 meters, the total length of the second medium flow channel is made to reach 0.3-20 meters, and finally it is achieved that the hot end temperature difference of the heat exchanger is lowered; and according to the method for increasing the number of the flow paths, the 2-20 flow paths are constructed in the inner structure of the heat exchanger or the 2-20 heat exchanger bodies constitute the 2-20 flow paths through series connection or the 2-20 heat exchanger bodies constitute the 2-20 flow paths through parallel connection and series connection. The heat exchanger with the 2-20 flow paths can achieve that the hot end temperature difference of the heat exchanger is controlled to be within 1 DEG C and is convenient to apply and popularize generally on heat exchange sites.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a heat exchanger with 2-20 processes. Background technique [0002] In daily life and industrial production, the temperature difference at the hot end of the heat exchanger used is large (the temperature difference at the hot end refers to the temperature difference between when the first medium flows into the heat exchanger and when the second medium flows out of the heat exchanger), the main reason is Yes: the length of the first medium and the second medium flow channel of the heat exchanger is not long, the heat exchange time of the two media is short, the heat exchange is insufficient, and the temperature difference at the hot end is large; if it is to be processed into the first medium and the second medium flow channel For longer heat exchangers, it is more difficult to process some types of heat exchangers with longer flow channels, some are too long and inconvenient to insta...

[0002] In daily life and industrial production, the temperature difference at the hot end of the heat exchanger used is large (the temperature difference at the hot end refers to the temperature difference between when the first medium flows into the heat exchanger and when the second medium flows out of the heat exchanger), the main reason is Yes: the length of the first medium and the second medium flow channel of the heat exchanger is not long, the heat exchange time of the two media is short, the heat exchange is insufficient, and the temperature difference at the hot end is large; if it is to be processed into the first medium and the second medium flow channel For longer heat exchangers, it is more difficult to process some types of heat exchangers with longer flow channels, some are too long and inconvenient to install, and some are too expensive

At present, there is a lack of a low-cost, easy-to-install heat exchanger with a small temperature difference at the hot end
