Plate heat exchanger possessing exterior passageway and welded structure in new type sealing way

A plate heat exchanger, a new type of technology, applied in the direction of heat exchanger shell, heat exchange equipment, lighting and heating equipment, etc., can solve the problem that the reliable sealing effect of the corner hole sealing gasket cannot be effectively guaranteed, and the sealing gasket is aging or hardened. , It is difficult to solve the problems such as the real sealing state of the corner hole sealing gasket, so as to achieve the effect of improving the scope of use, reliability and anti-leakage level, lasting sealing effect and low sealing cost.

Problems solved by technology

[0002] For all kinds of plate heat exchangers with outer channels and welded structures, the disadvantage is that due to the overall sealing of the outer channels, it is difficult to observe the corner holes of the inner channel with sealing gaskets in practical applications. The real sealing state of the hole sealing gasket, with the continuation of the product use time, due to the possible aging or hardening of the sealing gasket at the corner hole, and the existing product structure is difficult to effectively adjust the right The sealing gaskets at the corner holes have different compression and sealing degrees, so the existing product structure cannot effectively guarantee the reliable sealing effect of the corner hole gaskets

Embodiment Construction

[0021] As shown in the figure: in the specific implementation process, two heat exchange fins with inner channel corner holes are completely welded together at the periphery to form a heat exchange fin box 5 welded and sealed around the periphery. There are grooves for placing the inner and outer sealing gaskets on the outer periphery of the corner holes of the inner passages that exist in groups on 5, and the inner sealing gaskets 2 and the outer sealing gaskets 4 are placed in these grooves. 1. There is an anti-leakage observation hole 21 in the middle of the outer sealing gasket 2 and 4. The heat exchange fins of each heat exchange fin box 5 are provided with holes for welding and sealing at the observation holes. The heat fins are completely welded together at the periphery, and at the same time, the observation holes on the two heat exchange fins are also welded together, so that a ring-shaped leak-proof observation hole sealing weld 1 is formed around the observation hole...

Abstract

A novel sealed plate-type heat exchanger with external chnnel and welded structure features that the sealing pads for internal and external channels are arranged at the perforated corner of the welded and sealed casing, said sealing pads have an observing hole for observing if there is the heat exchanging medium in the hole to determine whether the pad is sealed or not. In the prerequisite that the good sealing of external channe is ensured, the clamping width of front and back clamp plates is changed to regulate the tight level of said sealing pad for increasing its working pressure and reliability.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a plate heat exchanger. Background technique [0002] For all kinds of plate heat exchangers with outer channel and welded structure, the disadvantage is that due to the overall sealing of the outer channel, it is difficult to observe the corner hole of the inner channel corner hole with a sealing gasket in practical application. The real sealing state of the hole sealing gasket, with the continuation of the product's use time, due to the possible aging or hardening of the sealing gasket at the corner hole, and the existing product structure is difficult to effectively adjust during the use of the product. The sealing gaskets at the corner holes have different compression and sealing degrees, so the existing product structure cannot effectively guarantee the reliable sealing effect of the corner hole sealing gaskets. Contents of the invention [0003] The object of the present invention is ...
