Description

The two-phase closed type hot siphon space heater

The utility model relates to a kind of space heater, particularly a kind of two-phase closed type hot siphon space heater.

Existing indoor electric warmer has filling type, hot air type, infrared-type etc.The limitation that these space heater ubiquities are certain.Filling type space heater thermal inertia is big, and it is slow to heat up; Conduction oil is volatile under the high temperature, and accumulator pressure is risen, and easy oxidation deterioration, and the heating efficiency to the room is low under the low temperature.The quartz ampoule mechanical strength of infrared-type space heater is lower, and impact resistance is poor.Other space heater then exists heating surface charging, temperature distributing disproportionation and the condition of high temperature, avoids conductive body and combustibles are in contact with it, and problem such as can not use under wet environment.The indoor heat request that adds makes room temperature be elevated to the people rapidly to feel comfortable temperature at short notice.Accomplish in the short period of a few minutes or tens minutes, to make room temperature to be elevated to more than 20 ℃; and be not subjected to the influence of dried wet environment, needn't add or regularly replace working media, long service life; the safe earth leakage protective device that touches is arranged, and such indoor electric warmer is the development in future target.

Shortcoming at the prior art existence; the purpose of this utility model is to provide a kind of two-phase closed type hot siphon space heater; utilize high-tech achievement in research-two-phase closed type hot siphon; a kind of space heater is provided; make room temperature in the short period (6～8 minutes), be elevated to the human body temperature (more than 20 ℃, the intensification temperature difference is more than 15 ℃) that feels comfortably cool rapidly; thermal efficiency height (more than 97%); life-span long (can reach 15～18 years); with low cost; be not subjected to the influence of dried wet environment; needn't add or change working media (being not loss of working media); there is not exposed heating; the safe earth leakage protective device that touches is arranged; the space heater that the care and maintenance workload is few.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of two-phase closed type hot siphon space heater has two-phase closed type hot siphon, resistance-type heating, hilted broadsword key switch, bimetallic thermostat, overtemperature prote device, leakage current protector, timer; It is characterized in that the resistance-type heating is wrapped in the endotherm section of thermal siphon, and the thermal siphon endotherm section outer wrapping heat insulator of finishing in winding; Resistance-type heating, hilted broadsword key switch, bimetallic thermostat, overtemperature prote device, leakage current protector, timer are connected in the bus circuit; Heat release section at thermal siphon is equipped with the heat release fin, at the housing of space heater fan is installed; The mechanical part of space heater is by many thermal siphons or be made of an endotherm section and many heat release section communicating with it independently; The setting angle of thermal siphon is the 0-180 degree.

The material of the shell of two-phase closed type hot siphon is stainless steel or copper or carbon steel; Working media in the thermal siphon is distilled water or Dowtherm A.

By a kind of two-phase closed type hot siphon space heater of the utility model, overcome the shortcoming that prior art exists, reached the purpose of above-mentioned creation; The utility model can make room temperature be elevated to the people rapidly to feel comfortable temperature at short notice.

Below in conjunction with schematic diagram the utility model is done detailed explanation.

As shown in Figures 1 to 4, thermal siphon 1 is made of several parts: (1) metal tube 2, and by copper production, or by the stainless steel manufacturing, or by the carbon steel manufacturing of surfaces externally and internally Passivation Treatment, it has constituted the shell of thermal siphon sealing; (2) working media 3 plays heat exchange, is water or Dowtherm A or the ethanol through distillation.On structure, thermal siphon is made up of three parts: endotherm section 4, adiabatic section 5 and heat release section 6.The installation of thermal siphon and operating angle are 0～180 °.Behind the heat source temperature, the working media that is closed in the thermal siphon flashes to high-temperature steam to thermal siphon in heat absorption outside endotherm section 4 absorbs, and this steam arrives heat release section 6 with the speed near sound.Because vapor (steam) temperature can reach 250 ℃, under high like this medium temperature, the temperature of thermal siphon heat release section 6 outer walls can reach more than 230 ℃, and the temperature difference between the environment temperature is (medium temperature can be adjusted as required) more than 200 ℃, because the temperature difference is big, the thermograde height, the heat output of thermal siphon and environment strengthens, and environment is heated up rapidly.Working media is condensed into liquid flow and gets back to endotherm section 4 after the heat release section heat release in the thermal siphon, and thermal siphon comes to this circulation to the environment heat release.Thermal siphon is the vacuum metal pipe of a sealing, therefore the not loss of working media in the pipe.

Fig. 2 is a kind of of two-phase closed type hot siphon space heater circuit of the present utility model.Adopt the several sections resistance-type heatings 7 that insulation sheath is arranged in the circuit, each section is all carried out power and adjustment with hilted broadsword key switch 8; Temperature with steam in bimetallic thermostat that is installed in thermal siphon adiabatic section 5 or the pressure type thermostat 9 control thermal siphons; Temperature with steam in the overtemperature prote device 10 restriction thermal siphons that are installed in thermal siphon adiabatic section 5; Prevent accident with the electric shock earth leakage protective device 11 that is connected in the bus circuit; Automatically control heat time heating time with timer 12.To indoor heating the time, with the temperature adjustment temperature control button of element 9 to dextrorotation to the appropriate location, when needs keep room temperature constant temperature, the temperature adjustment temperature control button of element 9 is extinguished to the indicator lamp that counter clockwise direction goes on the single knife switch.Heating 7 directly is wrapped on the outer wall of thermal siphon endotherm section 4.On the outer wall of the endotherm section 4 that twines heating 7, wrap up heat insulator.

As shown in Figure 5, radiating fin assembles mode with adopting welding manner or thread connecting mode or interference being connected of thermal siphon heat release section.Several parallel resistor formula heatings are wrapped on the endotherm section, and every heating is controlled folding by hilted broadsword key switch separately respectively.After the endotherm section heat absorption, the working media that flashes to high-temperature steam enters respectively in the several heat release section that are connected with endotherm section, and utilizes radiating fin 13 that is installed in heat release section and quiet fan 15 enhance heats that are installed on the warmer housing 14.Can come the coarse adjustment heating power with the hilted broadsword key switch as required.

As Fig. 6, shown in Figure 7, the endotherm section of every thermal siphon all twines a resistance-type heating, and controls folding by hilted broadsword key switch separately respectively, and all heatings are connected in parallel in the bus circuit.
