Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to a double-walled plate heat exchanger. Background Technology

[0002] Heat exchangers are excellent equipment for heating, cooling, heat recovery, and rapid sterilization. Currently, the most commonly used heat exchangers are brazed heat exchangers and double-walled heat exchangers. Double-walled heat exchangers are made of many stamped corrugated thin plates spaced at certain intervals, sealed around the perimeter by gaskets, and overlapped and pressed together by a frame and a clamping screw.

[0003] The prior art patent application with publication number CN220288331U filters out large particulate impurities in the fluid medium through a filter box at the inlet, preventing large particulate impurities from entering the heat exchange plate assembly, avoiding blockage of the plate channels of the heat exchange plate assembly, avoiding reduced heat exchange capacity due to blockage, ensuring continuous production, and improving economic efficiency.

[0004] Descaling solution is added periodically through the dosing pipe. The solution mixes with the fluid medium and enters the heat exchange plate assembly. During the flow process, it descals the heat exchange plate assembly, removing the dirt attached inside the heat exchange plate assembly, preventing dirt accumulation inside the heat exchange plate assembly, and ensuring the heat exchange efficiency of the heat exchanger.

[0005] However, in order to prevent residue from accumulating and crystallizing on the inner wall of the heat exchanger during the use of current equipment, a filter mechanism is installed on the outside of the heat exchanger to filter the liquid during the liquid transport. However, after long-term use, the current filter mechanism installed on the heat exchanger needs to be completely disassembled and replaced, which is inconvenient.

[0006] Therefore, it is necessary to provide a double-walled plate heat exchanger to solve the above-mentioned technical problems. Utility Model Content

[0045] The shape of the arc-shaped disassembly block 8 is adapted to the shape of the first mounting groove 6. The use of the sealing groove 71 and the sealing block 72 can play a primary sealing role between the arc-shaped disassembly block 8 and the circular box 3. The arc-shaped blocking block 91 with the arc-shaped sealing gasket 92 can play a secondary sealing role after the arc-shaped disassembly block 8 and the circular box 3 are connected.
