Detailed description of the invention
As shown in Figures 2 and 3, the radiator 200 with antenna function that the present invention relates to, it is mainly used as the nothing of temperature measuring equipment
Line signal transmitting terminal, this radiator 200 is made up of metal material, typically uses the metallic aluminium that heat conductivity is high.It includes heat conduction master
Body 204 and some from be perpendicular to this heat conduction main body 204 axially direction extend radiating part 203 in the form of sheets, some this dissipate
The girth sum of periphery, hot portion 203 is more than or equal to 1/4th of the wavelength of the wireless transmission signal of predeterminated frequency.Heat conduction main body
204 and the radiating part 203 of some lamellars be one-body molded, heat conduction main body 204 is cylindrical, the cross section of radiating part 203 in
Circular or polygon or other shape, be illustrated with circular radiating part 203 and introduce in the present embodiment.Theory and practice is demonstrate,proved
Bright, existing portable transmitting antenna equals to or more than radio signal ripple frequently with the overall circumference of helical antenna, i.e. helical antenna
Long 1/4.When the 1/4 of a length of radio signal wavelength of antenna, transmitting and the reception conversion efficiency of antenna are the highest.Cause
This, the length of antenna will determine according to being launched and receive the frequency i.e. wavelength of signal.Only it is to be understood that corresponding launch and receive
Mid frequency just can calculate the wavelength of radio signal of correspondence by equation below, then is exactly right by the wavelength calculated divided by 4
The optimal antenna length answered.Frequency with the reduction formula of wavelength is: wavelength=300,000 kilometer/frequency=300000000 meter/and frequently
Rate (unit obtained is rice), in the present embodiment, the portable antenna length of design is calculated as follows: such as when the signal used
When frequency is near 433MHz, its wavelength=300000 kilometer/433MHz=300000000/435000000=300/435=0.69
Rice, then corresponding optimal antenna length should be 0.69/4, equal to 0.1725 meter.The radiator that the present invention relates to is with helical antenna
For model, when the dimensional requirement of helical antenna is applied on radiator 200, the girth of the most multiple radiating part 203 peripheries it
With should be greater than or equal to 0.1725 meter.
Preferably, above-mentioned some described radiating part 203 being axially uniformly distributed along heat conduction main body 204 in the form of sheets, and described
Radiating part 203 include the first radiating part 201 being positioned at bottom and at least one be positioned at the second of this first radiating part 201 upper strata
Radiating part 202, the girth of this second radiating part 202 periphery is less than the girth of the first radiating part 201 periphery, at the first radiating part
Hole 205, location is offered, for being connected with temperature measuring equipment on 201.In the present embodiment, radiating part 203 includes that four intervals set
The second radiating part 202 put and first radiating part 201, the girth sum of these five circular radiating parts is more than or equal to
0.1725 meter.Oxide treatments can be done in the surface of common radiator 200, processes rear surface insulation, forms insulating oxide,
Use therefore to radiator 200 to be made antenna, the present embodiment crosses upper metal the insulating oxide surface of aluminum thermal fin and leads
Electric layer, the metal that preferably metallic nickel equistability is high, while anti-oxidation, realize the effect of spreader surface conduction.
As shown in Figure 4 and Figure 5, it is provided that a kind of temperature measuring equipment, this temperature-measuring bolt is a kind of thermometric intelligence spiral shell monitoring electrical nodal
Bolt 300, this thermometric intelligent bolt 300 is identical with the structure major part in patent application CN201220716623.5, the main distinction
Being, thermometric intelligent bolt 300 eliminates the transmitting antenna 103 shown in Fig. 1, and uses radiator 200 effect to launch sky
Line.Thermometric intelligent bolt 300 includes housing 304 and the radiator 200 being mutually permanently connected, and arranges in described housing 304
Have temperature transducer 303 and wiring board 301, this wiring board 301 have radio circuit, the outfan of radiofrequency signal with
Described radiator 200 is conductively connected.In housing 304, it is additionally provided with thermoelectric generator 305 and the body of bolt 306, heat radiation simultaneously
Heat conduction main body 204 and thermoelectric generator 305 thermal contact conductance of device 200.Detail about thermometric intelligent bolt 300 can be joined
According to the introduction in patent application CN201220716623.5.Above-mentioned wiring board 301 is provided with the outfan electricity with radiofrequency signal
The conduction bullet pin 302 connected, when radiator 200 and housing 304 assembly connection, this conduction bullet pin 302 and radiator 200
On the first radiating part 201 of lower floor contact, form conductive contact, enormously simplify assembling process.
Actual application scenario according to portable antenna and condition, inventor has carried out actual test.First use a 15cm
Wire as antenna, enclose (as shown in Figure 1) around temperature-measuring bolt shell one, be patent application CN201220716623.5
In scheme.In actual test, the wireless transmit distance only about 20 meters of temperature-measuring bolt, analyzes and finds: due to ours
Fin material is the metallic aluminium of bulk, and the inner ring body of temperature-measuring bolt is also that the metallic copper of bulk is constituted, and electromagnetic wave is had by metal
The effect absorbed, adds that installation bottom surface is also metal ingredient, and antenna overhead distance is near, and a part of electromagnetic wave can be by Metal absorption.
Above-mentioned reason causes the wireless transmit distance only about 20 meters of temperature-measuring bolt, analyzes from technology and structure, and radiator is metal
Composition, and size also approximates close to conductor size, it may be considered that use as antenna, remove original antenna, both played
Radiator effect, can serve as again antenna, but also reduce assembly difficulty and process complexity, achieve many things at one stroke.The most online
Plate soldering surface mounted conduction in road plays pin, for connecting the outfan of radiofrequency signal and the above-mentioned radiator with antenna function, so fills
The radiating part of timing lamellar by compress conduction play pin just can naturally and RF output end compact siro spinning technology, radio frequency signal is with regard to energy
Being launched by radiator, inventor's spacious environment out of doors carries out wireless transmit distance to the temperature-measuring bolt of the present embodiment
Test, communication distance is fully achieved more than 50 meters.And the radiating part of multiple lamellars is circle, and is to be evenly distributed,
Through surveying this radiator with antenna function, also there is fine directivity.Radiator serves not only as the radiator of temperature-measuring bolt to be made
With, and can also be as the antenna of temperature-measuring bolt, two kinds of functions of an element, in place of being also the novelty of the present invention, actual test
Result be fully achieved the target of design.It is understood that the above-mentioned radiator with antenna function can be not only used for this
The temperature-measuring bolt of bright middle introduction, it is also possible to need for other in temperature measuring equipment of wireless transmitting function.
