Embodiment 1
[0027] refer to figure 2 As shown, a two-way shunt condenser includes a plurality of U-shaped hairpin tubes pierced on the fins, including a front row condenser 1 and a rear row condenser 2, and a total inlet pipe 8 is arranged on the front row condenser 1 , the total inlet pipe 8 is divided into two paths, which are respectively the upper air inlet pipe 3 and the lower air inlet pipe 4, and the upper and lower air inlet pipes are adjacently arranged, and the condenser includes 20 U-shaped hairpin pipes;
[0028] Among them, the upper air intake pipe 3 is connected to 3 U-shaped hairpin pipes in the front row and 4 U-shaped hairpin pipes in the rear row in turn, and then the jumper pipe 5 is connected to 1 U-shaped hairpin pipe in the front row to form the upper flow path. In this way, there are 8 upper flow paths U-shaped hairpin tube;
[0029] The lower air intake pipe 4 is connected to 4 U-shaped hairpin tubes in the front row, and then the jumper pipe 6 is connected to t...

The invention provides a two-path diversion condenser. The condenser is of a double-row structure and comprises a main inlet pipe, a main outlet pipe and a plurality of U-shaped pipes arranged on a fin in a penetrating mode. The main inlet pipe comprises an upper air inlet pipe and a lower inlet pipe close to the upper inlet pipe. The upper air inlet pipe is communicated with several front-row U-shaped pipes and several back-row U-shaped pipes in sequence, a jump pipe is communicated with the several front-row U-shaped pipes, and then an upper flow path is formed; the lower air inlet pipe is communicated with several front-row U-shaped pipes, a jump pipe is communicated with several back-row U-shaped pipes, and then a lower flow path is formed; the upper flow path and the lower flow path intersect in the front row to form a main flow path, and liquid in the main flow path flows to the main outlet pipe at last. The invention further provides an air-conditioner outdoor unit with the two-path diversion condenser. The condenser is even in diversion heat exchange, the temperature difference is controlled within 0.5 DEG C, and the problem of uneven diversion of the upper flow path and the lower flow path is effectively solved.
Description
technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration engineering, and in particular relates to a two-way shunt condenser and an outdoor unit of an air conditioner using the condenser. Background technique [0002] When the air conditioner heat exchanger is exchanging heat, there is a phase change in the pipeline. In order to achieve better heat exchange effect, it will take the form that one main pipe is divided into multiple pipelines or multiple pipelines converge into one pipeline. The fluid velocity of the refrigerant in the road is relatively stable, thereby increasing the surface heat transfer coefficient between the refrigerant and the tube wall, and improving the heat exchange capacity under the condition that the heat exchange area remains unchanged. For the two-way split flow of the double-row condenser, the positions of the front and rear rows and the air volume of the two lines cannot be exactly the same. [0...
