Problems solved by technology

However, this structure can only have a good defrosting effect on the evaporator on the side close to the electric heater, while the evaporator on the side far away from the electric heater receives less heat and has a poor defrosting effect.
In addition, when using this structure, assembly and disassembly are more troublesome.

Abstract

The invention provides a heat exchanger. The heat exchanger comprises a heat exchanger shell (10), heat exchange tubes (20) and heating tubes (30), wherein the two ends of the heat exchanger shell (10) are provided with support end plates (11); a heat exchange cavity is formed inside the heat exchanger shell (10); the heat exchange tubes (20) are arranged on the heat exchanger shell (10) through the support end plates (11), and extend in the heat exchange cavity; the heat exchange tubes (20) comprise a plurality of heat exchange tube segments (21) which are arranged in parallel on the support end plates (11) and connection tube segments (22) which are connected with the heat exchange tube segments (21); the heating tubes (30) are connected to the heat exchanger shell (10); at least a part of the heating tubes (30) are arranged among heat exchange tube segments (21) and / or the connection tube segments (22). According to the heat exchanger, at least a part of the heating tubes (30) are arranged among the heat exchange tube segments (21) and / or the connection tube segments (22), so that the heating area of the whole heat exchanger is increased, and a good defrosting effect is achieved.

Description

technical field [0001] The invention relates to a heat exchanger. Background technique [0002] After the air cooler evaporator is frosted, an electric heater needs to be used to defrost, and the existing electric heater is mostly fixed on a flat plate, and the flat plate is fixed on the bottom of the heat exchanger. However, this structure can only have a good defrosting effect on the evaporator on the side close to the electric heater, while the evaporator on the side away from the electric heater receives less heat and has a poor defrosting effect. In addition, when this structure is adopted, assembly and disassembly are relatively troublesome. Contents of the invention [0003] The invention aims to provide a heat exchanger with large heating area and good defrosting effect. [0004] In order to achieve the above object, a heat exchanger is provided according to the present invention, comprising: a heat exchanger shell, with support end plates at both ends, and a hea...
