A partition flow self-adjusting heat exchanger

Abstract

The invention relates to the technical field of heat exchange, and discloses a self-adjusting heat exchanger for zone flow. The zone flow self-adjusting heat exchanger includes a casing and a flow regulating mechanism, the casing is provided with a fluid inlet, an inlet chamber and a cooling chamber are formed at intervals in the casing, and the cooling chamber includes a first cooling zone and a second cooling zone that are parallel and spaced apart. The inlet of the first cooling zone and the inlet of the second cooling zone are both communicated with the inlet chamber; the flow adjustment mechanism is arranged in the inlet chamber to adjust the flow rate of the fluid flowing into the first cooling zone and the second cooling zone in the inlet chamber. The inlet chamber of the heat exchanger provided by the embodiment of the present invention is provided with a flow adjustment mechanism, and the flow adjustment mechanism can adjust the flow of the fluid flowing into the first cooling zone and the second cooling zone, so as to realize the adaptive adjustment of the heat exchanger. The distribution ratio of fluid flow between different cooling zones makes it better fit the heat load variation characteristics of different cooling zones under multiple operating conditions.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a self-adjusting heat exchanger for zone flow. Background technique [0002] The cooling water system is an important part of the ship's power system. It undertakes the cooling functions of exhaust steam, cooling water, lubricating oil and other working fluids, and is an essential link to ensure the safe and stable operation of the ship's power system. The heat exchanger is the key equipment of the cooling water system. In order to avoid occupying too much cabin space due to the scattered arrangement of multiple heat exchangers, the self-flowing ship power central cooling system usually adopts an integrated heat exchanger. Multiple parallel cooling partitions realize simultaneous cooling of multiple working fluids. However, under multi-working conditions, the dynamic heat load characteristics of each cooling zone of the integrated heat exchanger are significantly different...
