Abstract
The utility model discloses an electric heating fan, which comprises a machine frame, a fan, a control cabinet and a heater, wherein the fan is fixed on the machine frame, the heater is positioned at an air outlet part of the fan, the heater is a honeycomb type round barrel, electric heating wires are suspended in hollow holes of the honeycomb type round barrel, and the electric heating wires are not in contact with the barrel wall. Because the heater has a structure of the honeycomb type round barrel, the electric heating wires are suspended in the hollow holes without being in contact with the barrel wall, the structure is similar to the design of an air hole, and no dead corner exists because the electric heating wires are not in contact with the barrel wall, so hot air can uniformly pass through both sides of the heating wires, and the utility model has the advantages of large air quantity, small wind resistance and high heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of air-heater, particularly a kind of electric calorifier.
Background technology
The mode of heating of present domestic air-heater comprises these four kinds of modes of fuel oil, fire coal, combustion gas and electrical heating, the three kinds of mode of heatings in front are the mode of heating that needs to add fuel, poor thermal efficiency, thermal power transfer has only 70%, energy waste is serious, and use these several heating means generally all to need the equipment user to carry out the collection and treatment of waste gas waste material, if the bad of collection and treatment might pollute the environment, so this three kinds of mode of heatings and be not suitable for present energy conservation and environment protection.And use these three kinds of mode of heatings to have certain potential safety hazard, fortuitous events such as temperature control does not with great difficulty set off an explosion, fire, cause damage for people's property, even can have influence on people's personal safety, so these three kinds of mode of heatings uses is fewer and feweri.And Electric heating is easy to control with it, the advantage that does not produce waste gas waste material, safety and environmental protection is widely used now, but the heater of Electric heating generally adopts heating rod or connects stacks such as hot plate and assembles, the inhomogeneous thermal losses high efficiency of dispelling the heat is lower, and heating rod, heating plate life-span itself are not long, needs were changed several times in general 1 year, therefore also had the wasting of resources, the problem that production cost is high.
The utility model content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, to provide a kind of thermal conversion efficiency height, the air-heater of long service life.
The embodiment of a kind of electric calorifier that the utility model provides is achieved through the following technical solutions:
A kind of electric calorifier comprises frame, blower fan and heater, and blower fan is fixed on the frame, heater is positioned at fan outlet and goes out, described heater is the honeycomb type drum, is hung with electrical heating wire in the cavity of described honeycombed drum, and described electrical heating wire does not contact with the bucket wall.
With above-mentioned principal character, the empty wall of described honeycombed drum is provided with brace rod, and described brace rod supports the contact of electrical heating wire discord bucket wall.
With above-mentioned principal character, described electrical heating wire is a helicoidal structure.
With above-mentioned principal character, described electrical heating wire is 2080 nickel filaments.
With above-mentioned principal character, the air outlet of described blower fan is equipped with an electroheat pair sensor, and described electroheat pair sensor is connected with controller, the frequency of described controller control electrical heating wire power on/off.
With above-mentioned principal character, described heater afterbody is equipped with a thermocouple sensor, and described thermocouple sensor is connected with switch board.
With above-mentioned principal character, be separated with how fine heat-preservation cotton between described heater and the holster shell, described holster shell is a louver body.
Technique scheme has following beneficial effect: because the structure of the heater of this utility model embodiment is the honeycomb fashion drum, electrical heating wire is suspended in the cavity, the contact of heating wire discord bucket wall, the design of the similar wind-tunnel of this kind structure, because of electrical heating wire does not contact a barrel wall, no dead angle so hot blast can pass through from the both sides of heating wire uniformly, and air quantity is big, windage is little, the rate of heat exchange height.Adopt the helical form nickel filament as electrical heating wire, caloric value is big, the electrical heating wire long service life.Circuit is controlled in real time, and is easy to operate.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the front view of the electric calorifier that provides of the utility model embodiment.
Fig. 2 is the left view of the electric calorifier that provides of the utility model embodiment.
Fig. 3 is the front view that the thermotank of the electric calorifier that provides of the utility model embodiment amplifies.
The specific embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
, the blower fan 1 of this electric calorifier, be fixed on the frame 4 as an embodiment of the present utility model referring to Fig. 1, Fig. 2, blower fan 1 is a centrifugal blower; blower motor is a specific type of electric machine; have thermistor,, motor is carried out the overtemperature overcurrent protection by connecting the relay of switch board.There is heating chamber 12 at the air outlet place of blower fan 1, heating is equipped with thermotank 5 in the chamber 12, thermotank 5 is made up of heater strip and high frequency porcelain, heater strip is positioned at the high frequency porcelain chamber, thermotank 5 is fixed on the heating chamber support bracket 6, support bracket 6 with take out hand 7 and be connected, the thermotank surface is wrapped with heat-preservation cotton, the shell that contacts with heat-preservation cotton is a shutter, makes things convenient for equipment cooling.The heating chamber is connected with air outlet 13, and a thermocouple sensor 15 is equipped with at air outlet 13 places, measures the temperature of the wind that blows out, and thermocouple sensor is connected with switch board.The afterbody of thermotank 5 is equipped with a thermocouple sensor 16, and thermocouple sensor 16 is connected with switch board.Switch board panel 3 is equipped with a digital temperature control table 14, and by solid-state relay control heating wire make-and-break time, temperature reaches uniform temperature in the thermotank thereby make, and the temperature control model is the PID control model.
