Problems solved by technology

[0003] Its main disadvantage is that the transmission pipe is a continuous extension pipe, and the refrigerant liquid in the rear can only continue to evaporate after the steam in the front is discharged, so that there is a large vapor-liquid two-phase resistance in the pipe, resulting in low refrigeration efficiency

Embodiment 1

[0013] exist figure 1 In the first embodiment shown, the gas-liquid separation evaporator includes a transmission pipe 1 and a cooling fin 2; wherein, the transmission pipe 1 forms a multi-communication network structure composed of a large number of squares, and the nodes between the transmission pipes are formed by The multi-way connectors 11 are connected, which not only facilitates assembly, but also ensures the tightness of the mesh structure.

[0014] Refrigerant enters the evaporator from the left side, and is divided into two parts: vapor and liquid due to gravity. The gas passes through the upper part of the multi-communication network structure quickly, and the liquid flows into the lower part of the multi-communication network structure. Evaporation is realized under constrained conditions; since the gas and liquid are completely separated in this structure, the resistance of the gas-liquid two-phase flow is greatly reduced, which effectively improves the efficiency...

Embodiment 2

[0018] exist figure 2 In the shown embodiment two, the difference from the first embodiment is that the multi-communication network structure of the gas-liquid separation evaporator is honeycomb, and the connection nodes between the transmission pipes 1 are also connected by multi-communication. The head 11 is connected; compared with the first embodiment, the specific structure of the transfer pipe is changed, and the gas-liquid separation can also be realized. The inner and outer surfaces of the transfer pipe can be wrinkled, and the heat transfer area can also be increased to achieve the same effect.

[0019] In addition, the multi-communication network structure formed by the transfer pipes 1 in the evaporator may also be a three-dimensional grid structure.

Abstract

The invention provides a gas-liquid separation evaporator comprising transmission tubes and radiating fins. The transmission tubes are in a multi-way mesh structure. The radiating fins are distributed in parallel and are fastened to the transmission tube. The transmission tubes are bellows; joints of the transmission tubes are connected through multi-way connectors. The multi-way mesh structure allows gas-liquid separation, and heat exchange area can be increased effectively, heat dissipation is quickened. The gas-liquid separation evaporator has the advantages that gas-liquid flow resistance can be reduced effectively and cooling efficiency is improved.

Description

technical field [0001] The invention relates to the field of air conditioner accessories, in particular to an air conditioner evaporator. Background technique [0002] At present, the evaporator transfer tubes of commonly used air conditioners are mostly serpentine tubes, and the transfer tubes are covered with fins. The refrigerant is transmitted from the transmission tube, after absorbing heat, it is converted from a liquid state to a gaseous state, and then transmitted to the compressor. The fins closely connected with the transmission tube transfer heat, increase the heating area, and rely on air convection to dissipate heat. [0003] Its main disadvantage is that the transmission pipe is a continuous extension pipe, and the refrigerant liquid in the rear can only continue to evaporate after the steam in the front is discharged, which makes the pipe have a large vapor-liquid two-phase resistance, resulting in low refrigeration efficiency. Contents of the invention ...
