Description

Electric heating superconductive radiator

Technical field

The utility model relates to a kind of electric heating superconductive radiator.

Background technology

Existing superconducting radiator enclosure interior is the state of vacuumizing, and is filled with superconducting fluid in the housing, and the liquid level of superconducting fluid becomes gaseous state in lower housing portion after being heated, and rises rapidly, by rolling back lower housing portion under the housing heat radiation back cooling liquefy.This phase transformation is to carry out under vacuum condition, and its advantage is that heat transfer rate is fast, energy-saving and environmental protection.But because civilian radiator casing all adopts mild steel, the density of material is low, can not keep inner vacuum negative pressure condition for a long time, so product is very short service life, quality does not reach designing requirement.In the electric heater of radiator, electrothermal piece adopts wire or metal bar mostly, and its power consumption is big, and conversion ratio is low, and service life is short.Owing to exist above-mentioned shortcoming to cause existing superconducting radiator not become qualified commodity, limited in the field of heating extensive use.

The utility model content

The purpose of this utility model is that the shortcoming at prior art provides a kind of electric heating superconductive radiator, by changing the superconducting fluid heat transfer type and adopting novel heating element heater, can prolong product service life, and heat transfer rate is fast, good heat dissipation effect, low with hot expense.

The technical solution of the utility model is: a kind of electric heating superconductive radiator, comprise radiator casing, the housing upper end is provided with filling liquid mouth and the capping of covering on filling exit, the bottom is provided with closed heating in the housing, electrothermal piece is housed in the heating clamber, superconducting fluid is housed in the housing, it is characterized in that: the superconducting fluid liquid level is positioned at the housing upper end, the electrothermal piece that is contained in the heating clamber is made of face heating and the insulating support that is enclosed within on this element body, and insulating support is connected with the heating clamber inwall.

Described heating is to be made of high-temperature insulation base material and the conductive heating unit with characteristic of semiconductor that penetrates into this base material top layer.The manufacture method of this composite and to be applied in the patent No. be open in 98124724.5 the patent documentation.

The utility model has the advantages that:

1, the face heating that adopts of present technique reaches more than 10000 hours service life, than heating element heater long service life such as wire or metal bars more than 3 times; The face heating has electric conversion rate and is higher than 97%, the flames of anger, high temperature resistant, thermal field is uniform and stable, radiating surface is big, characteristics such as quick heating, thereby improved quality, the performance of present technique.

2, be located at high-temperature insulation support between face heating and the heating clamber inwall, both played the effect of insulation, isolation, stationary plane heating, make the face heating heating surface reduce coverage rate again, radiating effect is further improved.

3, in radiator casing, completely adorn superconducting fluid, do not vacuumize in the housing, do not have negative pressure, liquid heat conduction, the heat transfer type of superconducting fluid has reduced the requirement to case material, and present technique is made housing with aluminum alloy materials, and product quality is qualified, uses durable.Superconducting fluid have to heat absorption, conduction rapidly, heat conduction characteristic such as have a narrow range of temperature, dispel the heat evenly, these good characteristics are not fully exerted in radiator casing, make product also get application market widely in field of heating.

4, the suitable single household of electric heating superconductive heat supply, multi-user, many rooms are controlled respectively, and heating according to need is by paying with heat, can cut the waste, compare advantage such as present technique has no pipe network, no large tracts of land to be taken up an area of, do not have discharging, easy to maintenance, and operating cost is low with traditional hot-water heating central heating.
