resistance to compression formula brazing formula plate heat exchanger contains a plurality of sheets and the front and back end plate that is used for the stack of two kinds of different heat exchange fluid heat transfer, on the front and back end plate, be equipped with fluid inlet and fluid outlet, all be connected with the import pipe on the fluid inlet, on the import pipe, all be connected with one section decompression pipe, the decompression pipe includes elasticity shell and the double-deck wave decompression structure of setting in elasticity shell, and between the double-deck wave decompression structure, it has inert gas to fill, the material of double-deck wave decompression structure is corrosion-resistant rubber.
Preferably, the double-layer wavy pressure reduction structure and the inlet pipe are sealed by a sealing and fixing ring.
Preferably, a fluid distributor with a multi-layer distribution hole is arranged in the fluid inlet, and two conical through holes are symmetrically formed in the lower outer side of the fluid distributor so as to balance fluid pressure and enable fluid to be distributed among layers more evenly.
The invention has the beneficial effects that:
the pressure-resistant brazing type plate heat exchanger is ingenious in structure, pressure can be effectively buffered and absorbed through the double-layer wavy pressure reducing structure through the arrangement of the pressure reducing pipes when heat exchange fluid with higher pressure or pressure suddenly changed in the heat exchange process is exchanged, damage and deformation of plates can be effectively avoided, the service life of the heat exchanger is greatly prolonged, inert gas is filled between the double-layer wavy pressure reducing structures, and the inert gas cannot expand when the double-layer wavy structures expand, so that the double-layer wavy pressure reducing structures are protected from being damaged, the durability is good, and the improvement of the existing heat exchanger is very convenient.
