Description
Technical field
The present invention relates to ptc heater testing equipment field, specifically a kind of ptc heater power detection device.
Background technology
Ptc heater refers to temperature automatically controlled PTC-ceramic heater, is a kind of special ceramic material.It has that thermal resistance is small, change
The high advantage of the thermal efficiency, is a kind of automatic constant-temperature, the electric heater of power saving.An its big outstanding feature is in security performance,
Surface " rubescent " phenomenon such as electric heating tubing heater will not be produced under any application, even if meeting fan trouble stalling
When, ptc heater is because cannot fully radiate, and its power also can drastically decline automatically, and now the surface temperature of heater is maintained
In Curie temperature or so（Typically about 250 DEG C）, so that the potential safety hazards such as scald, fire will not be caused.
PTC heater has constant temperature warming, the flames of anger, thermal conversion rate is high, influenceed minimum, natural life-span long by supply voltage
Deng the incomparable advantage of conventional heating element, the application in air-conditioning, warm-air drier, electric heating appliance is more and more extensive.
Air-conditioning, warm-air drier are all forced convection formula firing equipments, and how a major issue of design produces PTC
Heat is taken away in time, and this depends on the design in blower fan and air channel.The wind speed being applied on whole PTC heater windward side is equal
Even, otherwise the efficiency of heater will be greatly affected, and PTC-element can not give full play to respective ability.Wind speed is reasonable,
The consumption power and air outlet wind speed of PTC heater are closely related, wind speed increase, power increase.
Under actual conditions, ptc heater power is just have selected in the equipment design phase such as air-conditioning, warm-air drier, so PTC adds
The design and detection of hot device power, it is necessary to determined that before final assembly, after can not possibly both having waited until that final assembly was good, then
Test and determine in complete machine, it is also not possible to be special to do a complete machine for ptc heater incoming test from now on, unlike electric heating tubing
Heater does not need blower fan and air channel, and direct-electrifying just can be or direct by measuring resistance with readout power under rated voltage
Calculate.Therefore, in the case where the equipment such as air-conditioning, warm-air drier wind speed parameter is determined, detection means analog machine is utilized
Wind speed, to design and detect that ptc heater power is the approaches and methods of i.e. science and economy.
The content of the invention
It is an object of the invention to provide a kind of ptc heater power detection device, for ptc heater power with wind speed
Change determines under design wind speed the present situation of power there is provided a kind of detection method of Sciences Economics and dress, it is necessary to air channel
Put, smoothly adjust blower voltage by using pressure regulator, that is, adjust rotation speed of fan, to obtain design wind speed, so as to measure design
PTC power under wind speed.
Technical scheme is as follows：
A kind of ptc heater power detection device, includes pressure regulator, blower fan, air channel, ptc heater, anemobiagraph and electricity ginseng
Instrument, it is characterised in that：The air outlet of the blower fan is connected with the air inlet in the air channel, and the power input of blower fan passes through institute
Pressure regulator connection power supply is stated, described ptc heater and anemobiagraph is respectively arranged in the air outlet in the air channel, ptc heater
Power input pass through it is described electricity ginseng instrument connect power supply.
Described ptc heater power detection device, it is characterised in that：Described ptc heater, which is installed on, is arranged on institute
State in the ptc heater frock of duct outlet.
The present invention smoothly adjusts blower voltage using pressure regulator, that is, adjusts rotation speed of fan, and the air outlet in air channel is obtained
Design wind speed, so as to measure the power of ptc heater under design wind speed, performance number is directly read on electricity ginseng instrument.
The present invention is by changing ptc heater frock, under wind speed needed for can measuring all size ptc heater each
Power.
Beneficial effects of the present invention：
1st, the present invention changes, it is necessary to air channel for the power of ptc heater with wind speed, and determines under design wind speed showing for power
There is provided a kind of detection method of Sciences Economics and device for shape.
2nd, the present invention smoothly adjusts blower voltage by using pressure regulator, that is, adjusts rotation speed of fan, to obtain design wind speed,
So as to measure the power of PTC under design wind speed, easy to operate, measurement is easily obtained.
3rd, the present invention is by changing ptc heater frock, under wind speed needed for can measuring all size ptc heater each
Power, versatility is good.
4th, the instrument that the present invention is used is routine test detecting instrument, it is easy to buys, can take into account other testing inspection projects
With versatility is good, and input cost is low.
5th, the present invention is a kind of technology and process innovation, greatly increases the speed and incoming test quality of research and development of products
Control.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 be in Fig. 1 A to structural representation.
Fig. 3 is each member connection structure theory diagram of the invention.
Embodiment
Referring to figure accompanying drawing, a kind of ptc heater power detection device includes pressure regulator 1, blower fan 2, air channel 3, PTC and added
Hot device 6, anemobiagraph 4 and electricity ginseng instrument 7, the air outlet of blower fan 2 are connected with the air inlet in air channel 3, and the power input of blower fan 2 leads to
