Technical field
The utility model is a kind of electric heater device that utilizes the heat pipe for thermal conductivity principle, relates to a kind of improvement of electric heater.
Background technology
The main heat conduction form that adopted of the family expenses electric heater of Chu Xianing has in the market: conduction oil conducts (as the filling type electric heater, be filled with the conduction oil of high temperature refining in the body, caloric value is bigger, and temperature rise speed is slower, volume is bigger), the electrothermal wire heating, utilize blower fan or natural air convection current conduction (as the quartz ampoule electric heater, the halide torch electric heater, heat transfer type is the optical heat radiation conduction heat of heater, profile is small and exquisite, heat is transmitted fast, but has naked light hidden danger, and it is little to produce heat; Warm-air drier then is to improve room temperature by the blower fan blow air heating of flowing through, and is in light weight, but certain noise is arranged during work).The electric heater of these heat-conducting modes all can't overcome deficiencies such as potential safety hazard slow as heating up, that fan noise is arranged, have naked light to produce when working simultaneously.It is necessary overcoming the above problems.
The utility model content
The deficiencies such as potential safety hazard that the purpose of this utility model is to overcome that the intensification that the family expenses electric heater of common heat conduction form exists is slow, fan noise is arranged, have naked light to produce during work, a kind of family expenses electric heater device is proposed, utilize heat pipe principle, realize the quick transmission of calandria heat, with its surface temperature of rapid raising and have characteristics such as high thermal efficiency by the liquid medium gas-liquid phase transition.
The technical scheme that a kind of heat pipe electric heater of the present utility model is adopted, its structure is characterized in that referring to Fig. 1-4: this device mainly includes the lower guide heat pipe 6 of upper guide heat pipe 2, heat pipe 3, heat sink 4 and built-in calandria 7; Its version is: the upper and lower end of the vertical heat pipe that is parallel to each other 3 more than two that is provided with connects upper guide heat pipe 2, the lower guide heat pipe 6 of horizontally set respectively, and heat sink 4 is connected with the pipe face of heat pipe 3; Wherein, connect between heat pipe 3, upper guide heat pipe 2, the lower guide heat pipe 6 and connect and compose closed inner chamber, after injecting liquid medium pure water 5 in the closed inner chamber, vacuumize this device of formation.
Described a kind of heat pipe electric heater is characterized in that: upper guide heat pipe 2 is provided with the valve body 1 that can inject liquid medium.
Described a kind of heat pipe electric heater is characterized in that: calandria 7 is elongated tubular, and the heating of built-in external power supply is closely filled dielectric between heating and the shell.
Described a kind of heat pipe electric heater, it is characterized in that: heat pipe 3, two identical metallic plates that have groove of heat sink 4 and lower guide heat pipe 6 usefulness are replaced, two metallic plates are crimped on together, wherein, heat pipe 3 is replaced by the sphere of movements for the elephants shape grid cavity of the mutual perforation of suppressing on the metallic plate, lower guide heat pipe 6 is replaced by the tubular cavity of metallic plate lower press, and heat sink 4 is replaced by the remainder on the metallic plate, and heat pipe 3 is interconnected with lower guide heat pipe 6 and forms airtight cavity.
Heat pipe in this electric heater adopts the good material of thermal conductivity to make, and after injected media accounted for 1/4 to 1/3 pure water 5 of total measurement (volume) in heat pipe, used the airtight back that is evacuated.The bearing capacity of each heat pipe is not less than 1.2MPa.
Heat sink has effectively increased the area of dissipation of this device in the electric heater device, and the heat that helps device inside is dispersed in the external environment condition faster.Wherein, calandria is positioned at the bottom of device, and heat sink is positioned at the top of device, helps finishing Natural Circulation like this.Vacuumize to reduce the boiling point of heat-conducting liquid medium by connecting in each heat pipe that connects,, thereby make device have very fast programming rate so that promptly reach the phase transition temperature of liquid medium in lower temperature.Each heat pipe of electric heater device is airtight to have the bearing capacity that is not less than 1.2MPa, prolongation along with heat time heating time, apparatus surface temperature can constantly raise and arrive and stablize in the scope that allows, and the difference of heat pipe internal condition power supply input power is negative pressure or faint malleation.
Operation principle of the present utility model and process are: utilize liquid medium Natural Circulation cooling in the pipeline of sealing of heat pipe principle dependence self inside.In the closed inner chamber that constitutes by upper guide heat pipe 2, heat pipe 3 and lower guide heat pipe 6, inject common liquid medium-pure water 5, and during this device work of the state that is evacuated, heating energising in the calandria 7, fluid temperature in the lower guide heat pipe cavity will raise and become gas until boiling, thereby takes away the heat that is produced.Gas after the boiling rises in the heat pipe 3 that is connected with heat sink 4 and dispels the heat; At the top and upper guide heat pipe 2 places of heat pipe 3, gas and cool exterior air carry out being condensed into liquid after the heat exchange; Liquid after the heat radiation is back to again in the lower guide heat pipe, finishes a circulation.
Major advantage of the present utility model is: 1) programming rate is fast.Because heat pipe has very high thermal conductivity, thermal resistance is very little, and the heat that can rapidly calandria be produced conducts to the surface of this device.2) good heat dissipation effect.The heat pipe of Unit Weight can transmit the heat of several magnitude than silver, copper, aluminium etc. more, and the pyroconductivity of pure water is big, and is low at the vacuum environment mid-boiling point, and the effect of cooling is better than air-cooled.3) thermal efficiency height.This apparatus structure is simple, and intermediate link is few, and thermal losses is extremely low.4) surface temperature is even.This device is inner to be the hollow sealing structure, and has certain bearing capacity, can reach 120 ℃ or higher at the situation underlaying surface temperature a little more than normal pressure, and whole surface temperature difference is very little.5) noiseless.This device does not have moving component, does not produce noise during work.6) appearance and size is little.This installation weight is light, thin thickness, and it is little to take up room, and can also hang on the wall.7) environment friendly and pollution-free.Inner liquid medium is a pure water, can not produce any pollution.
