Heat exchanger structure

Abstract

The invention discloses a heat exchanger structure. The heat exchanger structure comprises a heat exchanger; the heat exchanger is in N folds; N heat exchanger sections are sequentially connected to form into the heat exchanger; a combination position is formed between adjacent two heat exchanger sections; the N which is an integer is greater than or equal to 2; the connecting mode between the adjacent two heat exchanger sections of at least one combination position is splicing; an included angle is formed between the spliced adjacent two heat exchangers; a groove is formed between the combination position of sliced adjacent two heat exchange sections and a position which is opposite to the included angle; the heat exchanger structure also comprises an electric heating device; the electric heating device is arranged inside the groove. The heat exchanger has the advantages of integrating the heat exchanger and the electric heating device and being convenient to install and detach and being small in occupied space and high in heat exchanging efficiency and efficiently improving the electric heating efficiency and air conditioning unit performances.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a heat exchanger structure with electric heating. Background technique [0002] The current air conditioner often uses auxiliary electric heating when the indoor mechanism is heated. For the sake of electrical safety, the auxiliary electric heating usually uses PTC electric heating. The characteristic of PTC electric heating is that the more air volume passing through the electric heating body, the higher the performance improvement. However, the installation position of the electric heating is generally located outside the evaporator, on the air outlet frame or the air inlet frame. This setting makes the electric heating device and the evaporator separate, which takes up a lot of space, and the electric heating efficiency is low, especially for the spliced ​​two-fold evaporator or multi-fold evaporator, the position of the splicing part, There is a certain space, and the air leak...

Problems solved by technology

This setting makes the electric heating device and the evaporator separate, which takes up a lot of space, and the electric heating efficiency is low, especially for the spliced ​​two-fold evaporator or multi-fold evaporator, the position of the splicing part, There is a certain space, and the air leakage here is relatively serious. If it is sealed with a sponge, there will be a flammable safety hazard. If it is not sealed, the heat exchange efficiency will not be high
