Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of novel soaking thermostatic oven, comprises body of heater 13, constant temperature heating device, heat-insulation layer 11 and furnace chamber 1, and described furnace chamber 1 is arranged in body of heater 13, and constant temperature heating device is arranged on furnace chamber 1 bottom, constant temperature heating device comprises electric hot plate body 2, be placed in the heat-generating pipe 3 of electric hot plate body 2 inside, be positioned at metal guide hot plate 4 and the isolated tube 5 of heat-generating pipe 3 tops, the two ends of described metal guide hot plate 4 are fixed on heater 1 top, described heat-generating pipe 3 is the shape of " playground runway ", the middle part of described heat-generating pipe 3 is provided with temperature monitoring element 6, and heat-generating pipe 3 is all connected with controlling organization 7 with temperature monitoring element 6, after described heat-generating pipe 3 energisings, be heat energy by electric energy conversion, between the metal guide hot plate 4 of heat-generating pipe 3 and its both sides, be equipped with the metal isolated tube 5 of hollow, by the isolated tube 5 of setting up between heat-generating pipe 3 and metal guide hot plate 4, replace part metals electric hot plate body between the two, reduce the area of hot transmission, the heat transfer speed effectively having slowed down between heat-generating pipe 3 and metal guide hot plate 4, after electrocaloric effect work, the temperature collecting when temperature monitoring element 6 is during higher than setting value, and controlling organization 7 is stopped power supply to heat-generating pipe 3 at once, and the temperature collecting when temperature monitoring element 6 is during lower than setting value, and controlling organization 7 restores electricity, because the heat transmission that temperature monitoring element 6 is subject to is more direct, rapidly, be subject to heat supply and stop the intensification of heat supply and the impact of cooling extent is also much bigger, the setting of described isolated tube 5, allow the difference variation of metal guide hot plate 4 become more much smaller than the difference variation of temperature monitoring element 6 regions, under identical attemperating unit and identical temperature control value conditions, setting up also of isolated tube 5 just reduced the temperature change scope of metal guide hot plate 4 effectively, and then dwindle object to be heated in metal guide hot plate 4 temperature difference in heating process, realize its relative constant temperature, be controllably heated, in described isolated tube 5, be filled with iron sand or lead, make the isolated tube 5 can be by the low iron sand of thermal conductivity factor, the plumbous effect that play " heat transfer buffer " to metal guide hot plate 4, quit work at heat-generating pipe 3 but still continue the time period that metal guide hot plate 4 is conducted heat, dwindle the scope of metal guide hot plate 4 temperature rises, pass through iron sand, lead is stored heat-generating pipe 3 and is passed to the heat of isolated tube 5, and constantly to metal guide hot plate 4 " heat release ", the in the situation that of heat-generating pipe 3 discontinuity heating, metal guide hot plate 4 still can be heated constantly, dwindle the scope that metal guide hot plate 4 temperature decline, thereby reduce the variations in temperature of metal guide hot plate 4 in heating process, dwindle the temperature difference, make the heating condition of the relative constant temperature of object to be heated in metal guide hot plate 4 more stable, filler generally selects iron sand or lead (specific heat capacity is greater than the material of aluminium to thermal conductivity factor lower than aluminium relatively) comparatively desirable, filler is under the condition of its constancy of volume, temperature raises or decline absorbs or liberated heat is large, the better effects if of storage, thereby make the even hot
