Embodiment Construction
[0046] The inventors found that the reason for the breakage of the gas distribution branch pipe was that the frequent opening of the compressor caused thermal expansion and contraction of the gas distribution main pipe under the influence of temperature, and excessive stress at local locations resulted in broken pipes. In order to effectively solve the broken pipe problem of the condenser gas distribution branch pipe, and to judge the failure mechanism of the pipeline from the perspective of thermal fatigue, the original copper pipe is replaced with a rubber hose in the middle of the gas distribution main pipe, which can effectively solve the problem of branch pipe failure. Broken pipes and refrigerant leakage of gas branch pipes.

The invention provides an optimization method of a condenser pipeline, a condenser, an outdoor unit and an air conditioner. The optimization method comprises the steps that a three-dimensional model of the outdoor unit is obtained, the outdoor unit comprises the condenser and an air distribution header pipe, the condenser comprises a heat exchange core part, and the air distribution header pipe is connected with a plurality of air distribution branch pipes and communicates with the heat exchange core part through the plurality of air distribution branch pipes; and a thermal stress value of the joint of each air distribution branch pipe and the air distribution header pipe is obtained, and an optimization suggestion for the structures of the air distribution header pipe and / or the air distribution branch pipe is given according to the size relationship between the thermal stress value and a preset stress value, so that the thermal stress value of the joint of the air distribution header pipe and the air distribution branch pipe is lower than the preset stress value. According to the optimization method of the condenser pipeline, the condenser, the outdoor unit and the air conditioner, the pipeline design of the condenser can be more reasonable, and the phenomena of pipe breakage of the gas distribution branch pipes and refrigerant leakage caused by the heat effect of the condenser in the prior art are effectively avoided.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a condenser pipeline optimization method, a condenser, an outdoor unit and an air conditioner. Background technique [0002] According to statistics, there are two types of leaking units: the leakage of the branch pipe of the condenser connected to the root of the bell mouth (side plate) and the leakage of the branch pipe of the gas distribution: the operating strain of the broken pipe (20μ, far from the target threshold), the opening and closing of the strain (200μ , far from reaching the target threshold), the transportation stress of the whole machine, and the pipeline mode (68Hz, not near the compressor operating frequency of 50Hz) cannot explain clearly the problem of broken pipes in the gas distribution branch, and the relevant test reports all meet the technical requirements. [0003] The above analysis method is the usual analysis and processing metho...
