Heat exchanger and kitchen air conditioning system applying same

Abstract

A heat exchanger and a kitchen air conditioning system applying the same are characterized in that heat transfer pipes of the heat exchanger are connected between collecting pipes on two sides, the heat transfer pipes are distributed at intervals along the length direction of the collecting pipes, radiating fins are mounted between the adjacent heat transfer pipes, and the radiating fins are distributed at intervals along the length direction of the collecting pipes. The number of the cooling fins in unit length is gradually increased or decreased, and a first connector and a second connector are arranged on the collecting pipes on the two sides respectively. A heat exchanger of the kitchen air conditioning system is arranged in a smoke exhaust channel of an oil smoke suction assembly, and a second heat exchanger is arranged in an air outlet channel. According to the kitchen air conditioning system, the dense part of the cooling fins corresponds to a large air volume part, and the sparse part of the cooling fins corresponds to a small air volume part, so that air flowing through the heat exchanger is more uniform, and the heat exchange effect of the heat exchanger is improved; oil smoke can take away heat or cold of the heat exchanger, and then the air conditioner energy efficiency is improved.

Description

technical field [0001] The invention relates to a kitchen air conditioning system, in particular to a heat exchanger and a kitchen air conditioning system using the heat exchanger. Background technique [0002] The fin-and-tube heat exchanger is the most commonly used heat exchanger in the field of refrigeration and air conditioning, and has the advantages of simple structure, reliability, and low cost. The heat exchange tubes of the existing fin-and-tube heat exchanger are generally made into multiple rows and multiple columns, and the number of tube rows in the same heat exchanger along the airflow direction is equal. The advantage is that the shape of the fin is rectangular, and the processing technology is simple. However, there are still the following problems in actual use: the number of tube rows of the heat exchanger should not be too many, otherwise the airflow resistance and noise flowing through the fins will increase, and the power consumption of the fan will al...

AI Technical Summary

Problems solved by technology

However, there are still the following problems in actual use: the number of tube rows of the heat exchanger should not be too many, otherwise the airflow resistance and noise flowing through the fins will increase, and the power consumption of the fan will also increase.

However, these air-conditioning hoods often combine the simple functions of the traditional air-conditioning indoor unit and the traditional range hood, and the outdoor unit of the air-conditioning still needs to be installed outdoors separately. , the pipes and line connections of the air conditioner's internal and external units will also damage the wall

[0004] In order to improve the heat dissipation effect, there is also a structure in which the heat exchanger is installed in the smoke exhaust chan
