The utility model is characterized in that the heater can be used directly in the fluid. The utility model has the advantages of safe and credible usage, increased heating area, improved heat exchange rate; therefore, the effects of energy saving and environmental protection are achieved.
Description
The utility model relates to a kind of heating element that is used for heating liquid, particularly relates to a kind of semiconductor heating element that can directly be placed in the liquid.
At present, heater mainly contains following two big classes: a class is that combustion gas is Instant heating type, and this class heater thermal conversion rate is lower, can produce pernicious gas in the use, contaminated environment, and normal owing to gas leakage causes inflammable, explosive and human casualty accident; Another kind of is Electrothermic wire and heating tubular type, such heating element is owing to use traditional exothermic material, and in use, heating temp is very high, area of dissipation is little, and the temperature difference between the liquid is big, and radiator is prone to corrosion, produces incrustation scale, easily electric leakage, coefficient of safety is not high, and useful life is not long, and thermal conversion rate is low.Since the semiconductor exothermic material comes out, multiple semiconductor liquid heater has also appearred, and mostly be liquid greatly and pass through in the heat dump the inside, reach the purpose of heating, the semiconductor heating element that is placed directly in the liquid does not then occur as yet.
The purpose of this utility model is to provide a kind of and can directly be placed in the liquid and safe and reliable semiconductor heating element, so that increase the heating surface area of liquid, improves heat exchanger effectiveness, and reaches energy-conservation and environment protecting.
For achieving the above object, the utility model provides a kind of semiconductor heating element, this heating element has a metal heat sink 1, in the cavity 11 of metal heat sink, semiconductor heat generating component 2 is housed, metal electrode 3 is equipped with in the both sides of this heat generating component, be connected with power line 5 on the electrode, separate by insulating material 4 between metal electrode and the radiator.
Described semiconductor heat generating component 2 is made of multi-disc semiconductor heating sheet 21, and they are arranged at intervals in the cavity of metal heat sink 1 vertically.
Described metal heat sink 1 in a tubular form, the outer heat-dissipating fin 15 that is provided with of its pipe, the one end passes through solder up, other end ferrule, radiator cavity inner wall and its interior member of adorning fit tightly by punching press, and punching press retraction slot 12 and outer punching press retraction slot 13 in being respectively equipped with on its inside and outside wall, the radiator two ends and outside an opening 14 is respectively arranged on the close flank sheet of punching press retraction slot.
The sealed end of metal heat sink 1 and flange 6 are affixed, and also are provided with temperature sensor mounting pipe 7 and sealing ring 8 on the flange.
Good effect of the present utility model is, owing to adopted current state-of-the-art exothermic material---and semiconductor heating sheet, and metal heat sink is close on the heating sheet, thereby make thermal conversion efficiency significantly improve; Because the outside of metal heat sink is provided with the heat dissipation metal fin, not only increased the endotherm area of liquid, reduced the temperature difference between liquid and the radiator, also increased intensity of radiator, reduced the thickness of metal material, the plane that makes radiator and heater be close to is more flat, so thermal conversion rate is higher, reaches purpose of energy saving.During the work of this heating element, not so the flames of anger burns, and does not have waste gas to discharge, and pollution-free, noiseless is the environment-friendly type heating element.This heating element has adopted novel heater element, its metal electrode and radiator separate fully, the power supply terminal exit passes through encapsulation process, keep dry, temperature is not high during again because of the work of its exothermic material, and radiating surface is big again, so, its security performance is very high, long service life, and thermal conversion rate can remain unchanged.This heating element manufacture craft is simple, and cost is low, and the practicality height can directly replace traditional electrical heating wire or heat-generating pipe, and can dry combustion method.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an overall structure longitudinal profile schematic diagram of the present utility model.
Fig. 2 is a cross-sectional structure schematic diagram of the present utility model.
Fig. 3 is the not preceding cross sectional representation of punching press of metal heat sink.
At first consult Fig. 1, Fig. 2, semiconductor heating element of the present utility model has a metal heat sink 1, this metal heat sink in a tubular form, its pipe internal cavity cross section can be square, rectangle, in this example, the radiator internal cavity is a rectangle.Radiator tube outer axially-aligned has circular heat-dissipating fin 15, to increase the area of dissipation of heating element.Use because of this heating element directly inserts in the liquid, so radiator must good seal.It inserts, and an end passes through solder up in the water.In the cavity 11 of metal heat sink, semiconductor heat generating component 2 is housed, this heat generating component 2 constitutes (referring to Fig. 1) by multi-disc semiconductor heating sheet 21, at interval suitably apart from being arranged in the cavity of metal heat sink 1, semiconductor heating sheet adopts commercially available PTC ceramic heating plate vertically for they.Metal electrode 3 is equipped with in the both sides of heat generating component, and electrode one end margin is fixed with the binding post with used for electric power connection, is connected with high temperature resistant power line 5 on it, and draws from radiator.Heating sheet and metal electrode can be adhesively fixed.For metal electrode and radiator are insulated fully, separate by insulating material 4 between the two, insulating material can adopt the good high-temperature insulation material of heat conductivility, as silica gel sheet, mica sheet etc.For semiconductor heat generating component and radiator are combined closely, be beneficial to heat conduction, after heat generating component, electrode and insulating material are packed radiator into, with stamping machine with the radiator cavity inner wall and in it member of adorning fit tightly by punching press.Punching press retraction slot 12 in being provided with on radiator inwall, punching press retraction slot 13, two retraction slots can inwardly shrink in punching course outside being provided with on outer wall, to reduce internal stress, avoid damaging radiator.The radiator two ends with outside an opening 14 is respectively arranged on the fin of the close side of punching press retraction slot, also play same effect.Power line exit at radiator is used ferrule.This end is also fixing with flange 6 welding, and flange then is used for being connected with heating container, also is provided with temperature sensor mounting pipe 7 on the flange, transducer can be fixed in the metal tube, and metal tube is then fixing with the flange welding.The sealing ring 8 with heating container sealing usefulness also is equipped with at flange proximal edge place.
