Description

TECHNICAL FIELD

[0001] The utility model belongs to heat exchanger technical field, concretely relates to a heat exchanger's liquid inlet protection structure. BACKGROUND

[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. The liquid inlet of the heat exchanger is an important part of the heat exchanger, and its design and position have important influence on the performance and efficiency of the heat exchanger. The liquid inlet of the heat exchanger is usually located at the lower part or side of the device, and the specific position depends on the type, structure and use scene of the heat exchanger. In the plate heat exchanger, the liquid inlet (including cold medium inlet and hot medium inlet) is usually distributed on the four corners of the device, or arranged on both sides of the device according to the flow configuration. This design helps the medium to form convection inside the heat exchanger, realizing effective heat exchange effect.

[0003] The existing heat exchanger liquid inlet is connected with the pipeline for use, and the two are generally fixedly connected by bolts. Since there is no anti-loosening structure, the connection mode may be loose after a long time of use, which will cause the sealing gasket to be unevenly extruded, thereby affecting the sealing performance and possibly causing safety hazards. Therefore, we propose a heat exchanger liquid inlet protection structure. UTILITY MODEL CONTENT
