Fig. 1 is the structural representation of the heater in the embodiments of the invention 1,
Fig. 2 is the structural representation that the air-conditioner of conventional heater is installed.
In the above-mentioned accompanying drawing, 1 is heater, and 2 is heating element heater, and 3 is inlet tube, and 4 is pipeline, and 5 is outlet, and 6,7 is dogleg section, and 8 is leg, and 9 is the end, and 10 is the side, and 11,12 is the installation site of sensor etc.
The specific embodiment
Come with reference to the accompanying drawings one embodiment of the present of invention are elaborated.Need to prove that the present invention is not subjected to the qualification of this embodiment.
Fig. 1 is the structural representation of heater of the present invention.Wherein, (a) being the front view of heater, (b) is its vertical view, (c) is its side view.
The housing 1 of heater is made of metal, and its inner filling has of the same race or different types of multiple metal, also can be filled into metal and liquid simultaneously.
The bottom of housing 1 is provided with leg 8, thereby can be arranged on the (not shown)s such as platform is set.
In addition, be provided with around the heating element heater 2 and be wound into spiral helicine pipeline 4, make refrigerant or water take place in the inside of housing 1 to flow, thereby obtain heat.
Refrigerant or water flow into from the inlet tube 3 of pipeline, flow out from outlet 5.
In addition, electric energy is imported in the heating element heater 2, makes in the heating element heater 2 and produces heat.
Like this, housing 1 is heated the heat that takes place in the element 2 earlier and heats, the pipeline 4 that the metal part of the housing 1 after being heated or fluid section will closely contact with it again heats, and will be heated at the refrigerant or the water of internal flow by pipeline 4 then.
Like this, refrigerant or water are flowing to the process of outlet 5 from inlet tube 3, are heated to the temperature of regulation.
Next, by Fig. 1 (c) formation being set in detail and it can being arranged to the mechanism that volume is little, the efficiency of heating surface is high of heating element heater described.
Fig. 1 (c) is the side view of heater, and pipeline 4 is wound into its cross section in the inside of housing 1 rounded.
And in the inside of housing 1, (2a~2d) is provided with heating element heater 2 to 4 positions on its cross section.
Distance between among 4 position 2a~2d any and the pipeline 4 is basic identical, is apart from d.Like this, the heat that produces in the heater can both carry out uniform heating to any position in the pipeline 4, and therefore the efficiency of heating surface to refrigerant or water can be improved.
In addition, heating element heater is by bending 3 times (just in time being 3 times among Fig. 1) at least, and therefore, the size of the length direction of heater 1 can shorten.
In addition,, therefore can increase pyroconductivity, improve the efficiency of heating surface owing to being filled with metal or fluid around heating element heater 2 and the pipeline 4.
In addition, owing to can store heat energy in the metal part, therefore when heater quits work, can also reduce the variations in temperature that refrigerant or water take place along with the variation of time, thereby can increase when starting and the starting performance after the defrosting, help to improve heating capacity.
Regarding to the temperature sensor or the excessive temperature rising protective device that are installed on the heater 1 down describes.
Heater 1 is owing to be structure that inside is provided with heating element heater 2 and pipeline 4, is covered by metal around it, so the temperature ascensional range of surface of shell is very big.
Therefore, must installation can play a protective role to the excessive rising of temperature temperature sensor or excessive temperature rising protective device.
Such temperature sensor or excessive temperature rising protective device are although should be arranged on the highest position of temperature; but; be preferably disposed on the most approaching position of distance between the surface of heating element heater 2 and housing 1 (as 12 places among Fig. 1), perhaps be located on the most stable position of the temperature of heater (as 11 places among Fig. 1).
The temperature of the core in the effective length of heater is generally the highest.Consider this situation, preferably also temperature sensor or excessive temperature rising protective device are located on the position shown in 12.
Therefore in addition, the serviceability temperature scope in the refrigerating circulation system is very big, and the situation that dewfall may take place for heater 1 ambient air also will be done sufficient consideration.
Therefore, the housing of heater 1 is configured to skewed.Like this, the water that produces because of dewfall from the teeth outwards can be guided to the direction opposite, thereby can prevent the generation of faults such as short circuit with the exposure portion of heating element heater 2.
The operable occasion of the present invention is as follows.Heater among the present invention be owing to can carry out high efficiency heating to refrigerant or water, therefore can also be applicable to the heater that the fluid to other kind heats.
