Description

Technical Field

[0001] The present invention relates to the technical field of plate heat exchangers, and more particularly to a high heat transfer plate heat exchanger for a pressure isolation station. Background Art

[0002] Pressure isolation stations are crucial components of centralized heating systems, primarily used to regulate the pressure and temperature of the heating network, ensuring safe, stable, and efficient operation. The plate heat exchangers used in these stations are highly efficient and compact heat exchangers, primarily used to transfer heat from the primary network (high temperature and high pressure) to the secondary network (user end), while isolating the pressure systems on both sides.

[0003] After searching, the Chinese patent with application number "CN202020010159.2" is specifically a plate heat exchanger with a microchannel that can improve heat transfer efficiency, including a front shell, an end plate, a plate and a mounting frame. The left side of the front shell is attached with an end plate, and the upper and lower sides of the front shell are both clamped and installed with positioning plates, and the right side of the positioning plate passes through a limiting hole, and the inside of the limiting hole is clamped and installed with an extrusion plate. The left end of the positioning plate is fixed to the mounting frame by a fixing bolt, and a protrusion is provided on the outside of the drainage groove to form an integrated structure with the plate. The first circulating fluid and the second fluid flow in the drainage groove, and the front shell and the rear shell are fixed by screws.

[0004] When the plate heat exchanger in the above patent is in use, it is connected to the conveying channel through a flange to facilitate heat exchange operations on the fluid. When the pressure of the conveyed fluid fluctuates and becomes unstable, the connected flange may become loose over a long period of time, causing the conveyed fluid to leak out, which may easily affect the heat exchange effect of the plate heat exchanger.

The cooling assembly 85 includes a fixed rod 851, which is fixedly connected to the front side of the movable ring 841. The front end of the fixed rod 851 is fixedly connected to an annular tube 852.

[0039] Working principle: When in use, the staff first connects the external pipe to the connecting pipe 6 through the connecting flange 7, and then performs heat exchange operation on the fluid through the heat exchange plate 2, and then rotates the rotating cap 846. The rotating cap 846 drives the threaded rod 845 to rotate. Under the action of the movable plate 844 and the connecting block 843, the protective cylinder 842 is controlled to move forward, which is convenient for protecting the connecting flange 7. At the same time, under the action of the fixed block 8415, the fixed ring 8416, and the connecting rod 8417, the inclined plate 8413 is controlled to rotate. Under the action of the fixed plate 1 847, the lifting block 849, and the mounting block 1 8410, the upper and lower support plates 8411 are conveniently controlled to open each other this year, which is convenient for the support plates 8411 to support and clamp the external pipe. At the same time, the protective tube 842 drives the stabilizing plate 8426 to move. Under the action of the control block 8423, the slide bar 8428 and the inclined groove 8430, the stabilizing plates 8426 on the upper and lower sides are controlled to approach the connecting flange 7, which is convenient for limiting the connecting flange 7 and increasing the stability of the installation of the connecting flange 7. At the same time, the moving ring 841 drives the piston ring 8419 to move. Under the action of the connecting hose 8432, the arc-shaped air bag 8427 is expanded, which increases the sealing of the installation of the connecting flange 7 and makes it difficult for the connecting flange 7 to leak fluid during heat exchange. During the heat exchange process, the air cooler 81 is started to make multiple nozzles 854 spray cold air on the connecting flange 7, which is convenient for cooling the connecting flange 7 and avoiding high temperature affecting the sealing of the connection of the connecting flange 7.
