Abstract

The present invention relates to an air-conditioner technical field, especially to solve the problem with descendent heat exchange capacity due to the pressure loss and the variance in the temperature in the refrigeration / heating process of the present air-conditioner to educe the heat exchanger structure of air-conditioner. The heat exchanger structure of air-conditioner of the invention includes a fin folding arrange made of aluminum foil and the 'U'-shape copper pipe reeved into the fin hole to form a cuboid integer evaporator and a condensator, characterized in that, the evaporator is along the refrigerant flow direction, and the diameter of the heat exchange copper tube diminishes, while the condensator is along the refrigerant flow direction, the diameter of the heat exchange copper largens. The heat exchanger with change in gauge makes the heat exchange capacity of the refrigerant advance, increases the refrigeration / heating capacity of the air-conditioner.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to the heat exchange design of the air conditioner system. , and the change of temperature leads to the problem of the decline of heat exchange capacity, and leads to the invention of the heat exchanger structure of the air conditioner. Background technique [0002] An air conditioner is an indoor climate control device, and its main components include a refrigeration cycle system including a compressor, a condenser, a throttling device, and an evaporator, and an air cycle system including a blower, an air duct, and an air inlet and outlet. The air conditioner absorbs indoor air, changes its temperature through the evaporator and condenser of the heat exchange device, and then discharges it back into the room to realize the functions of cooling or heating and dehumidification, so as to provide people with a fresh and comfortable indoor air environment. [0003] Gen...
