Description
Affiliated technical field
The utility model relate to a kind of electromagnetic oven heat radiation device, particularly a kind of electromagnetic oven totally-enclosed, exempt from fan, liquid cooling radiator.
Background technology
Present electromagnetic oven all adopts wind-cooling heat dissipating, i.e. open pore on housing, and the bottom is provided with fan, utilizes the forced convertion of air to dispel the heat, and the shortcoming of its existence is: 1, fan noise can't thoroughly be eliminated, and can not satisfy environmental requirement.2, fan sucks casing inside with oil smoke, steam, is adsorbed on the element and can't removes, and easily causes electromagnetic oven fault and the service life of reducing electromagnetic oven.3, owing to the use fan, necessary open pore, electromagnetic oven contacts with water often as kitchen range, and water inlet causes fault and jeopardizes personal safety easily.4, the service life of fan limited, thereby easy break-down causes the fault of electromagnetic oven.Because the wind-cooling heat dissipating shortcoming is a lot, thus need a kind of science more, rationally, the heat dissipating method of environmental protection substitutes present wind-cooling heat dissipating so that the overall performance that promotes electromagnetic oven with satisfy low noise, the high-quality market demand.
Summary of the invention
In order to overcome the shortcoming of existing electromagnetic oven in heat dissipating method and technical existence, it is a kind of totally-enclosed that the utility model provides, exempt from fan liquid-cooled electromagnetic oven heat radiation device, this radiator 1, because radiator does not have fan, so there is not noise fully, 2, because housing is totally-enclosed, so not oil suction of inside cigarette, do not intake, safe in utilization, 3, because the dual mode that adopts heat absorption to add heat radiation dispels the heat and carries out heat transmission in the mode of conduction, so radiating effect is very good, 4, the heat absorption bag constructions is simple, with low cost, long service life, fault rate is low, under the prerequisite that does not increase cost, the every performance indications that promote electromagnetic oven is had very high practical value and realistic meaning.
The technical scheme in the invention for solving the technical problem is:
A kind of electromagnetic oven heat radiation device, it comprises fin, shell, it is characterized in that: shell is a thermal conductivity good metal material radiating shell, the fin of sheet is installed on the high power valve or directly is fixed on the housing, liquid heat absorption bag is set between high power valve, coil and all heater elements and housing.
Aforesaid liquid heat absorption bag is a liquid sealing bag that thermal conductivity is good, and its side is provided with liquid injecting mouth, screw-cap, is provided with elastic fixing pole between inner two bags of walls, and injects suitable quantity of water.
Aforesaid liquid heat absorption bag is the liquid sealing bag of two one, and is respectively equipped with liquid injecting mouth, screw-cap, and the heat absorption bag that contacts with heater element injects an amount of transformer oil, and the heat absorption bag that contacts with housing injects suitable quantity of water, and the transformer oil mass is less than the water yield.
Aforesaid liquid heat absorption bag is two independently liquid sealing bags,
Aforesaid liquid heat absorption bag is the interlayer liquid sealing bag of an one, and the centre is a water bag, is the transformer oil bag on every side, and is respectively equipped with liquid injecting mouth, screw-cap.
Aforesaid electromagnetic oven heat radiation device, the cancellation fan is provided with rubber gasket between housing and panel.
When electromagnetic oven produces used heat, i.e. the bigger sheet fin of area is given in the conduction earlier of heat on the high power valve, and heat is disperseed the back conduction to liquid heat absorption bag, gives the bigger radiating shell of area by the conduction of heat absorption bag again.Simultaneously, the heat of coil directly conducts gives the heat absorption bag, gives radiating shell by the conduction of heat absorption bag again, with this heat is passed outside housing in housing, and distribute to the external world, in addition, because specific heat of water holds maximum in the heat absorption bag, be: erg-ten/gram ℃, that is: the hot merit of 1 ℃ of absorption of each gram coolant-temperature gage rising is an erg-ten, and the volume of heat absorption bag approximates the housing volume, adorns 2500 gram water approximately, when if the water bag temperature rises to 50 ℃ by 20 ℃ of room temperature, the used heat merit that it absorbed:
Q suction=cm Δ t=1 joule/gram ℃ * 2500 gram * (50 ℃-20 ℃)=75000 joules.
That is to say that the heat absorption bag is under the situation of not dispelling the heat fully, temperature will reach 50 ℃, needs to absorb 75000 joules hot merit
The used heat power of general 2000W electromagnetic oven is: coil: 25W, and transformer 6W, high power valve 20W, total used heat power is: 60W.Put=0.24I according to Joule's law: Q
2Rt, female law: the I in Europe
2R=P, derive: Q puts=and 0.24Ptt=Q puts/0.24P.
Because: Q suction=Q is put, so; T=Q suction/0.24P
T=75000 joule/0.24 * 60W=5208 (second)=86.6 (divide and plant)
The temperature of heat absorption bag that is to say: if will reach 50 ℃, under the situation of not dispelling the heat fully, need electromagnetic oven to produce 75000 joules used heat merit, and the required time is 86.6 fens kinds, in fact, in this endothermic process, because heat-dissipating casing is in ceaselessly heat radiation continuously, so, the temperature of water bag above time Rigen originally do not reach 50 ℃, even do not consider the heat accumulation function of water bag, as a heat conduction media, rely on large-area heat-dissipating casing directly to contact water bag with extraneous, used heat can not distributed by fan yet, as considering the heat absorption of heat absorption bag simultaneously, the heat sinking function of heat accumulation function and heat-dissipating casing then can substitute wind-cooling heat dissipating fully, realizes exempting from the purpose of fan liquid cooling heat radiation.
The beneficial effects of the utility model are: thus 1, since radiator do not have fan not have noise fully, 2, because housing is totally-enclosed, so not oil suction of inside cigarette, do not intake, safe in utilization, 3, because the dual mode that adopts heat absorption to add heat radiation dispels the heat and carry out the heat transmission in the mode of conduction, so radiating effect is very good, 4, the heat absorption bag constructions is simple, with low cost, long service life, fault rate is low, under the prerequisite that does not increase cost, the every performance indications that promote electromagnetic oven is had very high practical value and realistic meaning.
