Parallel flow evaporator core structure

Abstract

The invention provides a parallel flow evaporator core structure. A single parallel flow evaporator core thereof is equipped with a radiator, a tritorium, a gas collector and a reverse communicating gas separating tank and a return pipe and also uses a thin-wall parallel flow pipe band; a parallel type parallel flow evaporator core is formed by integrating a plurality of single parallel flow evaporator cores. Full liquid separation-gas collection, non-reverse parallel circulating refrigerant can be carried out in a full liquid separation parallel flow evaporation area, or, liquid separation-gas collection and gas separation-gas collection, reverse refrigerant circulating among parallel flow evaporating areas by the reverse communicated gas separating tank can be carried out in liquid separating parallel flow evaporating area and gas collecting parallel flow evaporating area according to the collecting-separating ratio. The invention effectively shortens the pipeline of the circulating refrigerant, increases the pipeline number, total cross sectional area and gross evaporation area of the circulating refrigerant, thus obviously improving the evaporation efficiency and reducing the production cost and energy consumption for the evaporator core. The technique scheme not only can further improve and upgrade the air conditioner evaporator technology and product, but also can improve economic benefit and save energy.

Description

Technical field: [0001] The invention relates to air-conditioning technology, in particular to core body technology of an air-conditioning evaporator. Background technique: [0002] The core body of the existing air conditioner evaporator, which is used to dissipate heat and circulate the refrigerant, is connected with the liquid distribution pipe of the liquid distributor assembly in parallel with a plurality of serpentine single-hole pipes or pipe strips, and the refrigerant is circulated at the same time. However, due to the small number of pipelines circulating refrigerant at the same time and the total cross-sectional area is small, the flow rate of refrigerant in the heat dissipation pipe is also small, and because of the serpentine heat dissipation pipe, the pipe wall is thicker, Moreover, the total heat dissipation area is relatively small, and the refrigerant is reversely circulated many times, so that the heat dissipation effect of the refrigerant in the serpentine...

Problems solved by technology

[0002] The core body of the existing air conditioner evaporator, which is used to dissipate heat and circulate the refrigerant, is connected with the liquid distribution pipe of the liquid distributor assembly in parallel with a plurality of serpentine single-hole pipes or pipe strips, and the refrigerant is circulated at the same time. However, due to the small number of pipelines circulating refrigerant at the same time and the total cross-sectional area is small, the flow rate of refrigerant in the heat dissipation pipe is also small, and because of the serpentine heat dissipation pipe, the pipe wall is thicker, In addition, the total heat dissipation area is small, and the refrigerant is circulated in reverse for many times, so that the heat dissipation effect of the refrigerant in the serpentine heat dissipation pipe is poor

These deficiencies are still very prominent on the core body of the existing air conditioner evaporator
