Description

Hot plate heat exchanger
Technical field
Hot plate heat exchanger of the present invention relates to a kind of heat exchanger, particularly a kind of hot plate heat exchanger that is used for the high-temperature flue gas waste heat recovery.
Background technology
In the existing high-temperature flue gas waste-heat recovery device, if flue-gas temperature very high (>800 ℃) adopts high temperature heat pipe heat exchanger mostly.High-temperature heat pipe is compared with general heat pipe as the main heat transfer unit of heat exchanger, has that thermal (temperature difference) stress is little, version simply, is not subject to advantages such as high temperature destruction.But its manufacturing cost height, processing technology complexity, shortcoming such as waste energy become the principal element that the development of restriction high temperature heat pipe heat exchanger is promoted.
Summary of the invention
The present invention is intended to overcome the problem of above-mentioned existence, and a kind of hot plate heat exchanger is provided, and this hot plate heat exchanger heat transfer area is big, uniform temperature is good, structural strength is high, low cost of manufacture, exist volume little, in light weight, all be significantly improved and improve than high temperature heat pipe heat exchanger performance, cost.
The objective of the invention is to be achieved through the following technical solutions: a kind of hot plate heat exchanger, to form by core body and dividing plate, described core body is made up of some hot plates, is separated by described dividing plate in the middle of described some hot plates surface, is divided into two medium channels up and down; Described hot plate is made up of vacuum liquid-charging passage and adapter.
The material of described core body can be aluminium, copper, stainless steel or the good material of other heat conductivility.
The section of described vacuum liquid-charging passage can be the shape of circle, ellipse, triangle, polygon etc., for example, and the rectangular channel of vacuum liquid-charging passage for being tightly connected and surrounding by upper and lower cover plate, side seal bar and underseal bar.
As a further improvement on the present invention, be provided with fin in described vacuum liquid-charging passage, described fin form can be sawtooth, porous, corrugated, but fin arrangement form horizontally-arranged, vertical row or inclination certain angle are arranged.
Described adapter is in order to vacuumize and to fill hydraulic fluid with the vacuum liquid-charging passage.
As a further improvement on the present invention, on the surface of described hot plate, be provided with some fins or fin, thus the heat transfer of enhanced water evaporation section and condensation segment.At this moment, described core body is made of the vacuum liquid-charging passage that several have fin or fin, and wherein the fin passage is separated into cold medium and hot media channel by a dividing plate, realizes that the cold fluid and hot fluid adverse current type flows.During use, the angle that heat exchanger integral body is vertical or tilts certain is arranged, to guarantee that the hydraulic fluid in the vacuum liquid-charging passage can be from cold medium section natural back flow to the thermal medium section.
It is stacked that the present invention will have the vacuum liquid-charging passage of fin, hot media channel and cold medium channel are arranged in juxtaposition, hydraulic fluid carries out transfer of heat by inner phase transformation in the vacuum liquid-charging passage, make between hot fluid and the cold fluid to form adverse current type and flow, have that uniform temperature is good, heat transfer area is big, structural strength is high, heat exchange efficiency is high, low cost and other advantages.Compare with high temperature heat pipe heat exchanger, cost descends 40%, and is easy to make.

The specific embodiment
The present invention is further described below in conjunction with accompanying drawing:
Embodiment 1
With reference to accompanying drawing 1, hot plate heat exchanger is made up of core body 100 and dividing plate 104.Core body 100 is made up of some hot plates 103.Hot plate 103 is had the vacuum liquid-charging path 10 2 of fin or fin 211,212 and is taken over 101 by several and constitutes.The surface of each hot plate 103 is separated into upper and lower two medium channels by a dividing plate 104 with fin, i.e. hot media channel 105 and cold medium channel 106 are realized the counter-current flow of hot fluid and cold fluid.Simultaneously, dividing plate 104 is connected as a single entity some hot plates 103.Adapter 101 is arranged on the top of vacuum liquid-charging path 10 2, and in order to vacuum liquid-charging path 10 2 is evacuated and fills hydraulic fluid, 101 modes of sealing of adapter can be welding or Sealing pliers etc. can make it reach the method for packing of complete driving fit.
With reference to accompanying drawing 2, vacuum liquid-charging path 10 2 front and back are provided with cover plate 221 and cover plate 222, and top is provided with takes over 201, has fin 211 and 212 on cover plate 211 and the cover plate 212.Inside is provided with vertical row's serrated fin 231.Adopt the vacuum brazing mode to connect between cover plate 221 and cover plate 222 and the serrated fin 231; Adopt the connected mode of common welding between adapter 201 and the vacuum liquid-charging path 10 2.
During work, hot plate 103 integral body are horizontal tilt and arrange or be arranged vertically, hydraulic fluid in the vacuum liquid-charging path 10 2 absorbs heat for 105 sections at hot media channel, evaporation becomes steam, moving to 106 sections condensation heat releases of cold medium channel becomes liquid, and heat is passed to behind the cold medium natural back flow to the thermal medium section.Rib structure 211 and 212 increases the heat exchange area of hot plate heat exchanger, has strengthened the heat transfer of hot plate heat exchanger.
Embodiment 2
With reference to accompanying drawing 3, the another kind of contour structures schematic diagram of hot plate heat exchanger.Difference with last example in the present embodiment is, cold side medium in the outside closed-loop of each hot plate 103 around the water leg 301 of hollow, each water leg 301 is provided with import and outlet, import and export are welded with takes over 311 and 312, arrow points is represented the flow direction of medium among Fig. 3, is generally low in and high out.During work, cold medium enters water leg 301 from entrance sleeve 312, hydraulic fluid in the vacuum liquid-charging path 10 2 absorbs heat in thermal medium section 105, evaporation becomes steam, move to the cooling medium release heat in 106 pairs of water legs of cold medium section 301, condensing simultaneously becomes liquid, and so forth circulation, make heat pass to cold medium in the water leg 301 continually, become thermal medium after the cold media heat absorption in the water leg 301 and discharge from discharge connection 311.Hot plate carries out work in the mode of phase-change heat transfer, also is added with rib structure 211 and 212 and water leg 301 simultaneously, therefore, and the heat transfer efficiency height.
