Embodiment 1

[0022] Embodiment 1, this embodiment proposes a parallel flow condenser 1, including a left header 1-1, a right header 1-1, and several refrigerants connecting the left header and the right header The branch pipe 1-5, the refrigerant branch pipe 1-5 is a flat pipe with a plurality of flow channel holes axially penetrating the flat pipe, and the gaseous refrigerant inlet pipe 1-3 and the gaseous refrigerant The outlet pipe 1-4, the left side header and the right side header 1-1 are respectively provided with spacers 1-2, which divide the internal flow channel of each header into a plurality of sub-flow channel areas, and each sub-flow channel The zone is connected with the corresponding refrigerant branch pipe to change the flow direction of the refrigerant, thereby adjusting the flow of the refrigerant inside the parallel flow condenser.

[0023] The number and arrangement of partitions in each header depends on the refrigerant in different states, preferably 1 to 4, and the i...

Embodiment 2

[0031] Embodiment 2. This embodiment proposes an air conditioner, on which the parallel flow condenser described in Embodiment 1 is installed. Part of the liquid refrigerant and compressor oil are introduced into the second half of the condenser by installing the above condenser, thereby greatly improving the heat exchange efficiency in the middle of the parallel flow condenser.

Abstract

The invention provides a parallel flow condenser. Two sides of the condenser are provided with collecting pipes; the collecting pipes are internally provided with multiple spacers used for separating internal runners of the collecting pipes into multiple sub-runner regions; the spacer behind the first sub-runner region is provided with a leak hole. By use of the characteristic that a liquid refrigerant has specific weight greater than that of press machine oil and is collected toward the bottom of the condenser under the action of gravity, each spacer of each collecting pipe of the parallel flow condenser is additionally provided with a flowing hole, and a part of liquid refrigerant and press machine oil can be guided into the rear half part of the condenser, so that the possibility that the liquid refrigerant or press machine oil is attached to the pipe walls of the collecting pipes is reduced, complete direct contact between a gaseous refrigerant and the pipe walls is ensured, and thus the heat exchange efficiency of the middle of the parallel flow condenser is improved. In addition, the invention also provides an air conditioner.

Description

technical field [0001] The invention relates to a microchannel parallel flow heat exchanger of an air conditioner, which belongs to the improvement technology of the microchannel parallel flow heat exchanger of an air conditioner. Background technique [0002] At present, the heat exchangers of commercially available air conditioners generally have two structures, namely tube-fin heat exchangers and micro-channel parallel flow heat exchangers. As a result, more and more air-conditioning manufacturers pay attention to it and are gradually and widely used in the new generation of air-conditioning products. There are three stages of heat exchange in the microchannel parallel flow condenser: cooling, condensation, and supercooling. The cooling stage is that the gaseous refrigerant is cooled from high temperature to the saturation temperature. The condensation stage is that the refrigerant keeps the saturation temperature unchanged, but the state gradually changes from the gaseou...
