Description

The superconductive medium electric heater

The utility model relates to the improvement of electric heater heat transfer medium and structure.

Electric heater is the auxiliary heating system that people generally select for use at present, because heat-conducting medium adopts traditional conduction oil, makes the oil medium type electric heater existence three of present listing big not enough:

One, environmental benefit is poor: when electric heater is scrapped, conduction oil can not reclaim, and 5 liters of conduction oils that fill in each electric heater are generally all outwelled arbitrarily, and consequent pollution is to be difficult to control.

Two, poor thermal efficiency: the oil medium type electric heater is retrained by the conduction oil characteristic, because oily programming rate is slow, causes the probationary period of warming oneself longer.The conduction oil operating temperature has also limited the surface temperature (generally being controlled in 70 ℃) of electric heater owing to thermograde difference between room temperature and warmer is little, and conduction of velocity is relatively slow, and indoor temperature rise is also slower.

Three, poor stability: because conduction oil characteristic decision electric heater can not improve temperature arbitrarily, when the temperature controller of electric heater malfunctioning, the oil temperature will obviously raise, when being heated, air in conduction oil and the oily spit of fland splashes the pressure that rises when surpassing design of shell compression strength, the electric heater shell will produce explosion, conduction oil will spray housing from the crack, and will be heavy then inside plant is scalded, gently then polluted to human body.

The purpose of this utility model is exactly at the problems referred to above, and the heating auxiliary equipment of a kind of green, energy-conservation, safety-type is provided.Its feature is as follows:

One, environmental benefit is good: only fill 500 ml water solution in the utility model, wherein solute adopts the NEW TYPE OF COMPOSITE chemical mediator, this medium is through the Machinery Ministry appraisal of scientific and technological achievements, State Scientific and Technological Commission, Machinery Ministry, Ministry of Construction's collaborative promotion are also assert, this composite chemical medium stable chemical performance, nonpoisonous and tasteless, do not produce any pollution.Scrap when electric heater, fill a small amount of chemical mediator that adds in the solution and can not pollute, reach the requirement of Green Product to environment.

Two, thermal efficiency height: the hot potential of the composite chemical medium boiling point that fills in the utility model low (55 ℃) volatilization vapour big (be water 1.5 times) fast (40cm/s) heat-conducting efficiency height (can reach more than 95%) the conductor surface temperature height (can reach 200 ℃) of conduction of velocity can make the utility model that quick heating is arranged thus, surface temperature is bigger than gradient with room temperature, conduction of velocity is fast, indoor temperature rise is also fast, and reduce conduction time relatively.Reach energy-efficient requirement.

Three, security is good: the composite chemical medium that the utility model is selected for use must be in subnormal ambient work, no matter therefore how high the electric heater temperature rise is, does not produce forward pressure in the container, and the situation that housing does not have explosion extremely takes place.Reach requirement safe in utilization.

Figure one is a structural representation of the present utility model.

Figure two is electrical schematic diagrams of the present utility model.

Be described further below in conjunction with a pair of concrete structure of the present utility model of accompanying drawing:

The utility model comprises housing 1, heating chamber 2, injects in composite chemical medium 3, the heating chamber 2 in the closed container of housing 1 and heating chamber 2 compositions and on plug-in mounting electric heater 4, the controller installing plate 8 switch 5, temperature controller 6 and fuse 7 are housed.

During use, when the access power supply, switch closure, electric current constitutes loops through fuse 7, temperature controller 6, switch 5, electric heater 4.Electric heater 4 heating work.Heat is passed to composite chemical medium 3 by the tube wall of heating chamber 2, because the superconduction heat effect of composite chemical medium 3, electric heater heats up rapidly and release heat, and the adjustment by temperature controller 6 can make the electric heater environment temperature remain on desirable scope.

Claims

One, the superconductive medium electric heater comprises housing 1, heating chamber 2, it is characterized in that: heating chamber 2 is positioned at housing 1 intracavity bottom, and synthesizes closed container with housing 1 structure.
