Description

Infraren radiator

The infrared emanation device is a kind of heater of infrared emanation element radiation heat conduction of energising, and device can be provided with thermostatic control, is mainly used in heating, baking and irradiation to object.

In general, mostly be two types of open and packaged types on the existing infrared spectrum irradiator structure.For open infrared spectrum irradiator, the infrared emanation element of its heating directly contacts with the space, though control the power of spectral illumination device at work with high, medium and low position switch, so that it is high and low to reach release temperature, but because the temperature height that the infrared emanation element discharges, direct contact need radiant matter surface is in order to avoid too much temperature can be damaged by the thermal radiation object.So just caused energy to run off at space segment, its efficient reduces.Such infrared spectrum irradiation utensil majority is the electric heating radiation appliance, be separated by with the fence and the external world, reach and prevent external object damaged in collision infrared radiating element, and prevent that human body from directly contacting infrared radiating element and electric heating radiation appliance and causing and burn, get an electric shock and bigger harm.Therefore this class infrared spectrum radiation utensil promptly can not utilize radiation efficiency more fully, and security reliability is also relatively poor.For existing industry, civilian infrared emanation stove and accessory is to belong to enclosed infrared spectral illumination device basically, and at work, after fire door was closed, object was by the infrared heat radiation in totally enclosed furnace chamber.When if object needs the regional area infrared emanation, the infrared emanation stove and accessory is not accomplished at all.Though in totally enclosed infrared heat radiation furnace chamber the thermal radiation energy loss seldom because the infrared emanation stove and accessory is subjected to the restriction of furnace chamber volume, equally also be restricted by the volume of thermal radiation object.

The purpose of this utility model be to provide a kind of can make full use of energy, can more constant steady radiant heat transfer to the infrared emanation device of object.

Infrared emanation device of the present utility model has housing, is loaded on the interior reflector of housing, is loaded on the preceding infrared emanation element of housing inner reflecting cover.The energising of infrared emanation element produces heat, to heat radiation all around.Through the reflector reflection, heat is mainly to previous irradiation.Its design feature is that the case panel of reflector and infrared emanation element front is an orifice plate.It promptly is not open having formed like this, neither enclosed thermal radiation heater.Heat to previous irradiation promptly is not the extraneous orientation of the face of penetrating that resembles the exploitation formula, neither seal retaining in housing, but hole and the appearance of part by orifice plate is radiated body surface and interior tissue, to excite the interior molecules energy by radiant matter soma, reaches the effect of radiation and heating.Also has the part heat simultaneously through the outside heat conduction of orifice plate.Object just can lean against orifice plate like this, determines the spacing in object and radiation heating baking source by orifice plate, guarantees the constant radiation heating of object.Because object can lean against on the orifice plate, all is radiated on the object from the radiation and the orifice plate radiation of passing the hole, can not loose to extraneous space, has effectively utilized energy.Can also quicken radiation heating and baking effectively to object heat conduction and radiation once more by orifice plate simultaneously.

In order to reduce the heat conduction of hard object radiation heating process and friction or to increase heat conduction and friction, have convex body at the orifice plate outer surface to soft object radiation heating process.Convex body preferably is arranged in the orifice plate outer surface.In order further accurately to control and utilize energy, constant steady radiation heating, the input of infrared emanation element preferably is connected with radiator valve, and the temperature-sensing element that is connected with radiator valve is positioned at housing.Produce the signal of telecommunication by the temperature-sensing element temperature-sensitive and feed back to the power supply of radiator valve control, reach the radiation temperature of accurate control infrared emanation device, also just guaranteed object radiation heating constancy to the infrared emanation element.Also the temperature of the multistage constant temperature of may command makes an infrared emanation device produce multiple radiation effect.The temperature-sensing element that is connected with radiator valve preferably is located at temperature-sensitive in the housing, to guarantee the accuracy of feedback signal.And radiator valve can link into an integrated entity with housing, as be arranged in the housing, also can be located at outside the housing, preferably radiator valve is located at outside the housing, become two bodies with housing, be connected lead and be provided with between radiator valve and infrared emanation element and the temperature-sensing element.Connect lead and also can be provided with attachment plug.Can reduce the volume and weight of device thermal radiation part like this, be convenient to operation, can also push plug aside and place respectively.Directly power supply is inserted the plug of infrared radiating element lead, can form the simple infrared heat radiation device of not being with radiator valve again.

The utility model system compares with the infrared spectrum irradiator that has has following advantage:

Outwards the orifice plate of radiation heating with directly contacted by the radiation heating object, make from the hole and radiation that orifice plate penetrates all is radiated on the object, outwards lost, made full use of energy, also can be by orifice plate to object heat conduction.

2. object leans against the orifice plate face by radiation heating, guarantees that object is not burnt out by the infrared emanation element, guarantees not damaged in collision inner member of object again.

3. can guarantee particularly can also control the radiation heating of constant temperature and multistage constant temperature exactly to the constant steady radiation heating of object.

4. the infrared emanation piece volumes of split is little, in light weight, can further reduce heat abstraction, the operation of being more convenient for.

Accompanying drawing has been represented a kind of split type infrared constant temp heat radiation device of the present utility model.Wherein Fig. 1 is a structural representation, and Fig. 2 is a heated at constant temperature control circuit schematic diagram.
