Abstract

The invention discloses a refrigerant flow equalizing device for a shell-and-tube heat exchanger. The refrigerant flow equalizing device comprises an inlet tube, an end cover plate, a first-stage distributor, a second-stage distributor, a tube plate and a heat exchange tube, wherein the end cover plate is arranged on one side of the first-stage distributor, the other side of the first-stage distributor is connected with the second-stage distributor, the tube plate is arranged on one side of the second-stage distributor, and the heat exchange tube is arranged on the tube plate; a first-stage cross-shaped distribution flow channel is machined in the side wall, close to the end cover plate, of the first-stage distributor, and the inlet tube penetrates through the end cover plate to communicate with the first-stage cross-shaped distribution flow channel; and a second-stage cross-shaped distribution flow channel is machined in the side wall surface, close to the first-stage distributor, of the second-stage distributor, and a third-stage distribution flow channel is machined in the other side of the second-stage distributor. According to the refrigerant flow equalizing device, a refrigerant working medium in the inlet tube is evenly distributed into the heat exchange tube, the overall working medium efficiency of the heat exchanger is improved, the flowing resistance and pressure drop in the distributor are reduced, waste of the heat exchange area caused by uneven working medium distribution is avoided, machining can be carried out through simple machining methods such as linear cutting and milling, and large-scale manufacturing and popularization are convenient.

Description

Technical field [0001] The present invention belongs to the refrigerant current distribution device, particularly a refrigerant current application applied to the housing heat exchanger. Background technique [0002] The housing heat exchanger has been widely used in many industrial sectors due to its advantages of simple structure, convenient processing. One of the important applications of the evaporator / condenser in the central air conditioner set is. As the evaporator working, the inlet working fluid is often in the flow state of the mixed flow of the gas-liquid, so it is necessary to flow into each heat transfer pipe, otherwise it will result in a difference in heat exchange between heat exchangers. Impact the overall work efficiency of the heat exchanger. Traditional pressure drop type refrigerant current flow devices, excessive pressure drop, complex structure, uniformity, etc., have adverse effects on heat exchange performance. Inventive content [0003] It is an objec...
