Description

A kind of heat-exchangers of the plate type

Technical field

GEOTHERMAL WATER art of heat transfer is the utility model is related to, more particularly to a kind of heat-exchangers of the plate type.

Background technology

Plate type heat exchanger is a series of a kind of high-performance heat exchanger formed by sheet metal closed assemblies with certain bellows-shaped. The runner of many small circulation sections is formed between each plate of heat exchanger, heat exchange is carried out by plate, it and conventional shell Pipe heat exchanger is compared, and under identical flow resistance and pump power Expenditure Levels, its heat transfer coefficient will be higher by a lot.

Heat-exchangers of the plate type heat-transfer mechanism is according to the law of thermodynamics, and " heat is always spontaneously transmitted to low by high temp objects Warm object, there is temperature difference in two kinds of fluids, with regard to necessarily having heat to be transmitted ", two kinds of fluids that temperature difference be present are being forced to pair Spread in thermal process, because heat transfer plate surface uses corrugation wave structure optimization design, its rate of heat exchange reaches 92%, certain Rate of flow of fluid under, motion of the fluid between plate is in three-dimensional motion, promotes fluid to form violent turbulent fluctuation, reduces boundary layer heat Resistance, augmentation of heat transfer efficiency.Corrugated plating not only increases turbulent flow Chengdu, and forms many strong points, it is sufficient to bears between medium Pressure differential.Flow, physical property, pressure drop and the temperature difference of fluid determine the quantity and size of heat transfer plate.How heat is improved Exchange efficiency is the Main way of the whole development of plate type heat exchanger.

Utility model content

Embodiment

It is further to the utility model below in conjunction with the accompanying drawings in order to be more clearly understood that the technical solution of the utility model Explanation.

Such as Fig. 1, a kind of heat-exchangers of the plate type shown in 2, including：Pillar 1, top guide bar 2, plate device 3, movable pressure plate 4, clamping screw 5 and lower guide rod 6, the plate device 3 are clamped by top guide bar 2 and lower guide rod 6 and clamping screw 5 and are assembled in Between pillar 1 and active clamped plate 4；The plate device 3 is connected setting with horizontal tilt certain angle α；The plate device 3 Combined by the connection of multiple plates 301, a of hole one, the b of hole two, the c of hole three and hole are respectively equipped with described each 301 4 angles of plate Four d, each hole size set different；Gasket seal 31 is provided between each two plate.Its a of mesopore one is identical with the d sizes of hole four, The a sizes of hole one are more than the c sizes of hole three, and the c sizes of hole three are more than the b sizes of hole two.

Preferably, the plate device 3 and horizontal tilt certain angle α<30º.

Operation principle：Such as Fig. 1, shown in 2, the plate device 3 that each plate 301 forms forms the pipelined channel to cold and heat succeed each other, Sealed between each plate 301 by gasket seal 31.GEOTHERMAL WATER enters from the d of hole four under the promotion of exterior power through a of via one Outflow, because plate device 3 with horizontal tilt certain angle α be connected setting, so GEOTHERMAL WATER is in addition to extraneous kinetic energy, There is a potential energy down in body, potential energy size is ρ_Waterɡ h, therefore the flow velocity of GEOTHERMAL WATER can accelerate, the turbulent extent of GEOTHERMAL WATER It can increase therewith, so as to reduce heat exchanged thermoresistance；On the other hand, can also hot water for corresponding reduction due to the presence of the potential energy Exterior power, so as to reduce energy consumption.And the cold water that need to be exchanged heat then enters from the c of hole three, from hole two, b comes out, due to plate device 3 Setting is connected with horizontal tilt certain angle α, compared with horizontal positioned, circulating chilled water, can also be corresponding there is also a potential energy The exterior power of cold water is reduced, so as to reduce energy consumption；Further, since the c sizes of hole three are more than the b sizes of hole two, so cold water goes out Hydraulic pressure it is powerful in water inlet pressure, so as to cold water flow velocity it is slack-off, extend heat-exchange time of the cold water in plate device 3, so as to Improve heat exchange efficiency.In addition, a sizes of providing holes one are more than the c sizes of hole three, it is greater than and need to changes so as to the flowing velocity of GEOTHERMAL WATER The chilled water flow velocity of heat, so as to also can further improve heat exchange efficiency.

The utility model is simple in construction, easy to operate, can increase the gesture of current by controlling the angle of inclination of plate Can, increase the turbulent extent of hot water and cold water, reduce thermal resistance, so as to improve heat exchange efficiency；Source pressure can also be reduced, so as to Reduce the energy consumption needed for supplying water；In addition, the current pressure between each plate is adjusted by the size of providing holes, to extend cold water With the heat-exchange time of hot water, so as to improve heat exchange efficiency.

Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
