Choke type liquid heat exchanger

Abstract

The invention discloses a flow stopping type liquid heat exchanger. The flow stopping type liquid heat exchanger is a seal shell in a column shape. A plurality of heat exchange pipelines in transverse installment are arranged inside the shell. One end of the heat exchange pipeline is connected to a heat exchange inlet and the other end is connected to a heat exchange outlet. A plurality of heat exchange disks are evenly distributed on a single heat exchange pipeline. A rounded spoiler is arranged in the middle of the heat exchange disk. A liquid passage is arranged between the spoiler and the heat exchange disk. The spoiler diameter is longer than the heat exchange pipeline diameter. The spoiler is fixedly connected to the inner side of the heat exchange disk through a locking strip. A plurality of flow stopping disks on two adjacent heat exchange pipelines are distributed in a stagger mode; the flow stopping type liquid heat exchanger solves the problem of short staying time of the heat exchange liquid in the heat exchange pipelines by adding linear heat exchange pipelines with a plurality of heat exchange disks to the heat exchange shell and meanwhile, the heat exchange disk stops a heat exchange medium from linear flowing in the shell through a flow stopping level and therefore staying time of the heat exchange medium in the shell is prolonged and heat exchange efficiency is significantly increased.

Description

technical field [0001] The invention relates to the technical field of liquid heat exchange, in particular to a flow resistance type liquid heat exchanger. Background technique [0002] Liquid heat exchange generally adopts single or multiple heat exchange pipes installed in the heat exchange shell side for heat exchange. Traditional heat exchange pipes are linear or spiral. For linear heat exchange pipes, the heat exchange The hot liquid flows in a straight line in the pipeline, and the residence time of the liquid in the pipeline is short, so it cannot fully exchange heat with the heat exchange medium, and the heat exchange efficiency is low; for the spiral heat exchange pipeline, the heat exchange fluid stays in the pipeline The residence time is longer, but because the pipeline itself is shaped, the pipeline occupies a large space in the shell, and only a few sets or one set of heat exchange pipelines can be installed in the same set of shells. It can be seen that the p...

[0002] Liquid heat exchange generally adopts single or multiple heat exchange pipes installed in the heat exchange shell side for heat exchange. Traditional heat exchange pipes are linear or spiral. For linear heat exchange pipes, the heat exchange The hot liquid flows in a straight line in the pipeline, and the residence time of the liquid in the pipeline is short, so it cannot fully exchange heat with the heat exchange medium, and the heat exchange efficiency is low; for the spiral heat exchange pipeline, the heat exchange fluid stays in the pipeline The residence time is longer, but because the pipeline itself is shaped, the pipeline occupies a large space in the shell, and only a few sets or one set of heat exchange pipelines can be installed in the same set of shells. Look, the pipeline and heat exchange area are small, and the heat exchange efficiency is also not high.
