Abstract

The invention discloses a parallel flow evaporator and the structure of a flow clapboard thereof and relates to a clapboard and a flat tube of a refrigeration air conditioning evaporator. The parallel flow evaporator comprises a first liquid collector tube, a second liquid collector tube and a flow clapboard for blocking refrigerant flow; a flat heat exchange tube allowing a refrigerant to pass is arranged between the first liquid collector tube and the second liquid collector tube, wherein the flow clapboard is formed by a first flow clapboard and a second clapboard; the first flow clapboardis provided with a liquid refrigerant supplementation hole; and the second flow clapboard is provided with a gaseous refrigerant discharge hole. The technical scheme of the invention can effectively improve the heat exchange efficiency of the evaporator by skillfully arranging the flow clapboard; and a triangle channel structure arranged in the flat tube in the technical scheme realizes that widest edges of all channels are exactly arranged on the side wall of the flat heat exchange tube, therefore more channels can be arranged for achieving higher heat exchange efficiency.

Description

technical field [0001] The invention belongs to the field of air conditioners, and relates to a partition plate structure and a flat tube structure of a refrigeration air conditioner evaporator. Background technique [0002] Most of the known parallel flow evaporators are composed of two rows of flat tubes, tube holders and partitions. It is the constant pursuit of the industry to find ways to improve the heat exchange efficiency of the evaporator. For this reason, technicians continue to work hard. [0003] For example, the published Chinese patent 200520025484.1 is a tube-type evaporator core body for automobile air conditioners, in which several intermediate laminated plate groups sandwiching the heat-dissipating inner fin strips are assembled side by side, and each end is equipped with an end sandwiching the heat-dissipating inner fin strips. The flow-laminated laminate group is assembled into a core body, and the core body is provided with upper and lower end flow chann...
