Abstract

The utility model provides an air-conditioner heat exchanger which can solve the defects of the prior art that the heat resistance is big and the heat transferring rate is low, etc. The utility model has a technic proposal of that the heat exchanger comprises two liquid dividing devices, a plurality of A/C pipes and wing pieces; the liquid dividing device is arranged at two ends; a plurality of A/C pipes are arranged by intervals between the upper liquid dividing device and the lower liquid dividing device; two ends of the A/C pipe are communicated with the liquid dividing device; the wing pieces are arranged between the A/C pipes and the wing pieces are welded with the A/C pipes each other. The utility model can be used in the outer machine of the air-conditioner and the touching heat-resistance can be removed and the heat exchanging rate of the heat exchanger can be enhanced because the mutual welding between the A/C pipes and the wing pieces is adopted.

Description

Air-condition heat exchanger

Technical field

The utility model relates to a kind of air-condition heat exchanger, relates in particular to the heat exchanger in the air-conditioner outdoor unit.

Background technology

At present, the heat exchanger in the existing air-conditioner outdoor unit mainly is a fin-tube heat exchanger, promptly round copper U-shaped pipe and aluminium fin.Heat exchange is to contact with the aluminium fin by the U-shaped pipe to carry out heat conduction realization.This version still exists some not to be attained and improves part, has following deficiency: 1. because the U-shaped pipe is inserted in the aluminium fin, be not tight the contact between part body and the fin, exist micro gap, make that the gap area thermal contact resistance is big, the heat exchange weak effect has influenced the Energy Efficiency Ratio of air-conditioning.2. the pipe windage is big, and the invalid heat exchange of afterbody zone is big.

How solving the deficiency of above-mentioned existence, then is the design problem that the utility model faced.

Summary of the invention

The utility model provides a kind of air-condition heat exchanger, and it can solve problems such as the big and heat transfer efficiency of thermal resistance that prior art exists is low.

Solve above-mentioned in-problem purpose in order to reach, the technical solution of the utility model is, a kind of air-condition heat exchanger, it is characterized in that described heat exchanger comprises two knockouts, some refrigerant pipes and fin, knockout is arranged on two ends, and two knockouts have been spaced some refrigerant pipes between up and down, and refrigerant pipe two ends are communicated with knockout, be fin between the refrigerant pipe, described fin and refrigerant pipe weld mutually.

In the utility model, also have following technical characterictic: be provided with refrigerant inlet pipe arrangement and refrigerant exit pipe arrangement on knockout, refrigerant inlet pipe arrangement is located at top; The refrigerant exit pipe arrangement is located at the bottom, and above-mentioned refrigerant inlet pipe arrangement and refrigerant exit pipe arrangement are located on the same knockout, or are located at respectively on two knockouts.

In the utility model, also have following technical characterictic: described refrigerant pipe is a porous flat pipe.

In the utility model, also have following technical characterictic: described fin pattern is ripple chip, bridge chip or the chip of windowing.

In the utility model, also have following technical characterictic: the fin between the described refrigerant pipe is a wave-like.

The utility model compared with prior art has the following advantages and good effect: 1. owing to adopt refrigerant pipe and fin to be welded to each other, eliminated thermal contact resistance, improved the heat exchange efficiency of heat exchanger.2. the fin between the refrigerant pipe is a wave-like, helps welding.3. the windage of oval aluminum pipe is little, and the invalid heat exchange of afterbody zone is little, has improved heat exchange efficiency.
