Abstract

A plate heat exchanger includes enhancing frusta assembling and welding on angle of aperture of' bottom heat exchange plate in plate heat exchanger angle of aperture channel, reducing to the product weight and material cost without influencing product assembling hardness and welding or sweat rate of finished products, when plate heat exchanger being work, heat transfer medium pressure divided by enhancing frusta, capable of avoiding product angle of aperture channel bottom outside raised deformation under media pressure action.

Description

In the angular hole path bottom plate type heat exchanger of strengthening frustum is housed

Technical field

The present invention relates to a kind of plate type heat exchanger, relate in particular to a kind of plate type heat exchanger that utilizes welding or soldering tech to make.

Background technology

The plate type heat exchanger of this utilization welding or soldering tech manufacturing is to fit together with the some heat exchange plates that are roughly rectangle or square and other shapes and have a fillet, on heat exchange plate, has heat exchange structure, by heat exchange plate on heat exchange structure form with concavo-convex brace rod bubble clocklike, by heat exchange plate on heat exchange structure form with ripple, in Figure of description of the present invention, the heat exchange structure on the heat exchange plate is formed with ripple.Have the hole, angle of being convenient to the medium circulation on these heat exchange plates, these holes, angle will form the angular hole path of heat transferring medium in plate type heat exchanger when these heat exchange plates link together.Soldered or the soldering of these heat exchange plates also can use glutinous stick or gasket seal to reach connection and sealing effectiveness between each heat exchange plate together.

The plate type heat exchanger of this utilization welding or soldering tech manufacturing can not be out of shape by evagination when working pressurized in order to guarantee its angular hole path bottom, usually will assemble outside the heat exchange plate of bottom and welding or soldering have baffle plate, the thickness of this baffle plate will be enough to resist the effect of operating pressure firmly and can not make the distortion of angular hole path bottom baffle evagination again.For the convenience of processing and assembling, general baffle plate is all made with the material of consistency of thickness, though the baffle plate of this material thickness unanimity can satisfy the instructions for use of product aspect operating pressure, but because the baffle plate thickness of non-angular hole path bottom does not need thick like this, so the welding of this barrier material consistency of thickness or brazing plate type heat exchanger, the weight and the cost of its product are higher.

For weight and the material cost that reduces product, welding that has or brazing plate type heat exchanger only outside the pairing product of angular hole path in the local area scope assembling and welding or soldering the thickening baffle plate is arranged, in other place then with thin barrier material.Though this way can reduce the weight and the material cost of product, this way has but strengthened the assembling difficulty of baffle plate and thickening baffle plate and has influenced welding or the brazing quality and the yield rate of entire product.

Summary of the invention

For satisfy welding or brazing plate type heat exchanger under operating pressure instructions for use and reduce the weight and the material cost of product, can not influence simultaneously the difficulty and the yield rate of product assembling, the invention provides a kind of welding or brazing plate type heat exchanger of strengthening frustum that in product, be equipped with bottom the angular hole path.

The technical solution adopted for the present invention to solve the technical problems is; In the angular hole path bottom welding or the brazing plate type heat exchanger of strengthening frustum being housed includes; Baffle plate, ozzle and heat exchange plate is characterized in that: hole, angle place's assembling of angular hole path bottom heat exchange plate and welding or soldering have the reinforcement frustum in product.

For the weight and the material cost of further reduction welding or brazing plate type heat exchanger, under the prerequisite that satisfies welding ozzle and product instructions for use, can in assembling and welding or soldering reinforcement frustum, cancel baffle plate.

For the ease of strengthening the assembling of frustum, this bottom heat exchange plate has the concavo-convex location structure of being convenient to this reinforcement frustum location at angle Kong Chu, on the baseplane of strengthening frustum corresponding concavo-convex location structure with it is also arranged simultaneously.

For the ease of the location of strengthening frustum and be convenient to assembling, before product overall package and welding can with the bottom heat exchange plate place, hole, angle with strengthen the mode that frustum adopts welding or soldering and electric resistance welding fixing point and carry out fixing in advance.

In order to reduce the fluid resistance of each runner between angular hole path and each heat exchange plate, the face shaping of this reinforcement frustum and cross section can and manufacture any suitable form by the demand design.

In a welding or brazing plate type heat exchanger, the reinforcement frustum all can be equipped with in the bottom of all angular hole paths, also can select the bottom of indivedual angular hole paths that the reinforcement frustum is housed.

This welding or brazing plate type heat exchanger can be considered to three kinds of common heat exchange of heat transferring medium and have six angular hole paths, also can be considered to two kinds of common heat exchange of heat transferring medium and have four angular hole paths.

The present invention has following advantage and good effect:

Assembling and welding or soldering have the reinforcement frustum on the hole, angle of welding or brazing plate type heat exchanger angular hole path inner bottom part heat exchange plate, can when strengthening the angular hole path bottom strength, reduce the weight and the material cost of product, and having concavo-convex easily location structure positions and assembles strengthening frustum, can also adopt the mode of welding or soldering and electric resistance welding fixing point to carry out fixing in advance with the reinforcement frustum at the place, hole, angle of bottom heat exchange plate, in order to reduce the fluid resistance of welding or brazing plate type heat exchanger inside, the face shaping of this reinforcement frustum and cross section can and manufacture any suitable form by the demand design.
