Description
The present invention relates to a kind of heat exchanger, relate in particular to a kind of plate type heat exchanger.
The present full formula plate type heat exchanger that looses is generally made packing ring at the periphery of every heat exchanger fin and passage place with goods such as rubber or asbestos and is sealed.Its shortcoming is: because the perimeter gasket sealing surface is longer, so heat transferring medium easily leaks in assembling and when using, packing ring is easily aging and damage, dependability and anti-leak level error, and operating temperature and operating pressure are lower.Current, also have both at home and abroad a kind of by the two boards sheet at periphery half of the box formula plate type heat exchanger that looses that forms welded together.Its shortcoming is: still need be at periphery place washer sealing between box.Because the periphery welding makes box that certain deformation be arranged, the seal washer anti-leak level of periphery is descended.For fear of the decline of this anti-leak level, this half diffusing formula plate type heat exchanger also has another assembling form.Promptly cancelled perimeter gasket, to put into a container by the heat exchange core body that box is formed, the heat exchange mode that to form wherein a kind of heat transferring medium be immersion type, thereby changed the heat exchange characteristic and the advantage of plate type heat exchanger, its major defect of heat exchanger of this immersion heat exchange form is: heat exchange efficiency is low.Have the welded plate type heat exchanger of part at present both at home and abroad.For example Chinese utility model patent 91227597.9.The characteristics of the welded plate type heat exchanger of this class are to adopt the integral solder structure.Its form or cancelled packing ring with bowl-shape plate, or replaced packing ring with metal profile.The welded plate type heat exchanger major defect of this class is: this kind heat exchanger is subjected to the restriction of integral solder structure and welding equipment and can not makes the product with big heat exchange area, especially be not suitable for the welding of the bigger plate of veneer area, thereby limited the scope of application of product.
The objective of the invention is to, make one and can improve operating temperature and operating pressure, can improve dependability and anti-leak level, the cancellation perimeter gasket and keep the plate type heat exchanger heat exchange mode, welding, that can be made into big heat exchange area applicable to the large tracts of land veneer, have a welded plate type heat exchanger.
The present invention is achieved in that it is to form a plate box by the heat exchanger fin that has 0～2 (group) hole above two in peripheral seal weld together.Heat exchanger fin should be designed at the periphery place can form welded together in pairs.After anti-leak detection, between box and the box, need not place seal washer at the periphery place between box and the pressure strip to weld seam on this plate box.The difformity made with any material and the washer sealing in cross section can be equipped with at internal channel mouth place, the removable heat exchange core body that is similar to half dissipating bind structure can be formed thus.This heat exchange core body has been inherited advantages such as the washer sealing plate type heat exchanger is removable, capable of washing, replaceable, changeable heat exchange area basically.And because only at internal channel mouth place washer sealing, its operating pressure and operating temperature can be greatly improved, and can correspondingly improve the dependability and the anti-leak level of internal channel.Also can be at the internal channel mouth place welded seal between box and the box.And will be near being welded with adapter on the box of pressure strip, so that make it stretch out the import and export that form internal channel outside the preformed hole on the pressure strip.Can form the heat exchange core body of welded non-disconnectable formula thus.The heat exchange core body of this non-disconnectable formula can reach inner purpose of cleaning with the Chemical cleaning mode.Simultaneously, the operating pressure of internal channel and operating temperature and dependability and anti-leak level etc. all will have bigger raising.Adopt welded seal as internal channel, then the internal channel mouth place on the box should be designed to directly to carry out mutually the form of ring packing welding.The elementary assembling that the present invention requires is similar to the assembling process of half diffusing formula plate type heat exchanger.It is by the removable heat exchange core body of similar half dissipating bind structure is housed between two pressure strips, or the heat exchange core body of welded non-disconnectable formula is housed, and combinations such as clamping screw, guide rod, fastening screw, pillar and screw rod sealing ring, guide rod sealing ring or seal cover are housed on pressure strip tighten and form.After pressure-bearing and anti-leak detection, just assemble in the tetrahedron that can between two pressure strips, form or outside carrying out on the surface internal channel.Outer assembling is meant the assembling to cover plate and upper and lower blind flange of outer tunnel and outer tunnel import and export etc.Cover plate and the upper and lower blind flange of outer tunnel are fastened on two pressure strips with packing ring and bolt etc., and make its sealing, thereby can form the outer removable plate type heat exchanger that is assembled into.If cover plate and the upper and lower blind flange of outer tunnel and screw rod, guide rod etc. directly are welded on two pressure strips, just formed the outer plate type heat exchanger that is assembled into the non-disconnectable formula of full welded seal.Also can be with parts part welded seals such as outer build-up member and screw rod, guide rods, part still adopts packing ring, and bolt seal etc. are formed the outer plate type heat exchanger that is assembled into half weldering formula.Outer assembling and no matter heat exchange core body adopts removable or adopt non-disconnectable welded type to comprise all welded type and half weldering formula etc. all allows partly or wholly to cancel fastening screw, pillar, bolt, clamping screw and guide rod and sealing ring and seal cover etc.If outer assembling adopts all welded type can also cancel the used seal washer of cover plate and the upper and lower blind flange of outer tunnel etc.Outer tunnel and import and export and internal channel import and export on product position, opening direction, quantity, shape and MEDIA FLOW to etc. all with actual practical and determine.That its medial and lateral of the upper and lower blind flange of cover plate and outer tunnel all can be made into the light face or have non-deformability add strong form.Its inboard can also have the device of effects such as (or making) line, afflux, shunting, water conservancy diversion and load-bearing, pressure-bearing and gripper shoe sheet box.These devices can be by internal channel hole on the plate (group) number and the multipaths form of formation heat transferring medium such as position, and heat exchange modes such as stream, crossfire and mixed flow also.Simultaneously, by devices such as outer tunnel different cross section shape and shunting, water conservancy diversion, can also improve the problem of many flaggies heat exchange inequality.In sum: its heat exchange mode of the plate type heat exchanger of this structure is: one of heat transferring medium is by the internal channel hole on the plate.Flow through plate one side and pass in and out with heat exchange, another heat transferring medium is that the another side by the plates of flowing through such as current-collecting device of outer tunnel and cover plate passes in and out with heat exchange.
