Description
The utility model relates to a kind of novel solder type plate type heat exchanger that is used for cold and hot medium heat exchange
In the prior art, field such as oil, chemical industry uses plate type heat exchanger to carry out heat exchange usually.As day the disclosure specially permit clear 61-276691 and disclose a kind of sealing ring template formula heat exchanger, though this heat exchanger heat transfer efficient is high, but the sealing ring made from rubber, graphite, plastic or other material usually between the heat transferring plate seals, these sealing rings leak sometimes, therefore the temperature and pressure that bears heat transferring medium is lower, and the scope of application is restricted.Chinese patent CN88217708.7 discloses a kind of solder type plate type heat exchanger, the method of welding with flanging between its heat exchange plate, therefore can not leak and bear higher temperature and pressure, but because the heat exchange plate group is mounted in the circular housing, the material of housing is generally carbon steel, and heat exchange plate is generally the corrosion resistant plate sheet material, because the difference of the coefficient of thermal expansion and contraction of two kinds of materials, when running into the higher heat transferring medium of temperature, between housing and heat exchange plate group, can produce bigger stress, thereby make the internal structure of plate type heat exchanger produce the crack, reduce the life-span of heat exchanger, thereby this plate type heat exchanger can not be high temperature resistant.In addition, the manufacturing of housing and installation will expend a large amount of man power and materials, and production cost is higher.
The purpose of this utility model provides that a kind of heat transfer efficiency height, compact conformation, floor space are little, high temperature resistant, the novel solder type plate type heat exchanger of high pressure.
The utility model is to realize like this, this novel solder type plate type heat exchanger comprises the heat exchange plate group that is made of heat exchange plate of vertical layout, heat exchange plate is corrugated cardboard sheet or flat board, between the adjacent heat exchange plate periphery with being welded to connect, plate groups has alternate cold and hot fluid runner, be characterized in that vertically respectively there is a pressure strip two sides of the heat exchange plate group of layout, fixedly connected with nut with horizontal pull bar between two pressure strips, form framework.The upper and lower bobbin carriage that is equipped with of heat exchange plate group, fluid inlet and outlet are housed respectively on the upper and lower bobbin carriage, two other side of heat exchange plate group is separately installed with side plate, two side plate upper and lower parts are equipped with fluid issuing and import respectively, and the heat exchange plate group, upper and lower bobbin carriage is in aggregates is fixed on the framework.Its operation principle is: between two pressure strips with cross-tie and the nut heat exchange plate group that is fixed and clamped, constitute fluid course between the vertically stacked adjacent heat exchange plate, a kind of fluid enters the upper tube box from import, flows into the alternate fluid course in the heat exchange plate group then.Simultaneously, the fluid inlet of one other fluid from side plate enters the alternate fluid course the heat exchange plate group.The heat exchange area that cold and hot fluid is passed through equates.Because the utility model has adopted heat exchange plate group, the upper and lower bobbin carriage structure that is fixed on the framework in aggregates, when running into the higher heat transferring medium of temperature, because the plate bundle that plate is welded into can freely stretch, reduced inherent strain, thereby made heat exchanger can be applicable to the heat exchange of high-temperature medium.When the temperature of heat transferring medium is higher, can selects for use thicker pressure strip to compress the heat exchange plate group, thereby also can be applicable to the heat exchange of high-pressure medium.In addition, the utility model takes not have shell structure, makes whole apparatus structure compactness, floor space little, has also reduced production cost simultaneously.Heat exchange plate of the present utility model adopts corrugated cardboard sheet or flat board, so the resistance of heat transferring medium is fallen little.
The periphery of heat exchange plate of the present utility model is a flanging, adopts the flanging welding between the adjacent plate, welds more firmly, prevents the leakage of heat transferring medium.
Be filled with filler rod between the adjacent heat exchanger plates sheet in the utility model, prevent the leakage of heat transferring medium.
The upper and lower bobbin carriage of the heat exchange plate group in the utility model has square or circular arc type, and the square or bobbin carriage of circular arc type and following square heat exchange plate group structure are complementary, and the upper and lower bobbin carriage of circular arc type is stressed better when pressure is high.
Framework in the utility model is formed and is comprised pressure strip, pillar and base plate.
Hot fluid runner and cold fluid runner in the utility model can exchange use.
The utility model is applicable to the heat exchange of gas-gas, solution-air, liquid-liquid.
The utility model compared with the prior art, following advantage is arranged: because adopted heat exchange plate group, the upper and lower bobbin carriage structure of plate internals on framework in aggregates, when running into high-temperature medium, the plate internals can freely be stretched, reduce the destruction of inherent strain, therefore be applicable to the heat exchange of high-temperature medium.Because the thickness of pressure strip can be adjusted according to pressure, thereby also is applicable to the heat exchange of high-pressure medium.In addition, the utility model adopts no shell structure, has reduced production cost, makes whole apparatus structure compactness, floor space little.Owing to adopted corrugated cardboard sheet or flat board to make heat exchange plate, so the resistance of heat transferring medium is fallen little.The utility model profile is a rectangular configuration, so the length and width consistent size of heat exchange plate, makes more convenient.
Now an embodiment of the present utility model is specified in conjunction with symbol figure.
