Description
Technical field
The present invention relates to a kind of electronic load instrument.
Background technology
A kind of electronic load instrument is the electronic equipment for testing power parameter.A kind of electronic load instrument includes metal shell
With each component being installed in housing.Some louvres are opened up on a kind of housing of existing electronic load instrument, with to each unit
Device produce heat radiated, this kind of radiating mode radiating effect is not good, if a kind of electronic load instrument be positioned over ventilation it is poor
Place, a kind of internal temperature of electronic load instrument raises fast, and internal component rationally cannot be radiated, and easily causes one
There is error in the test result for planting electronic load instrument, even more so that a kind of electronic load instrument cannot normal work.
The content of the invention
In view of the shortcomings of the prior art, the purpose of the present invention is intended to provide a kind of electronic load instrument, its rapid heat dissipation,
Excellent in heat dissipation effect.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of electronic load instrument, it includes housing, two radiator fans, processor, temperature sensor and two circuit boards；Two radiation airs
Fan, processor, temperature sensor and two circuit boards are mounted in the housing；The two opposite side walls of the housing respectively open up some equal
The thermal vias of even arrangement；The gas channel of the thermal vias for connecting two opposite side walls, two radiatings are constituted between two circuit boards
Fan is respectively positioned at two ends of the gas channel；The temperature sensor is used to detect temperature in a kind of electronic load instrument,
And generate corresponding temperature signal；The processor is used for the temperature signal of the temperature sensor and default temperature threshold signal
Compare, when temperature signal is more than temperature threshold signal, the processor drives two radiator fans to rotate；It is small in temperature signal
When temperature threshold signal, the processor stops driving two radiator fans.
Further, the temperature sensor uses the temperature sensor of model PT100.
Further, the processor is single-chip microcomputer.
Beneficial effects of the present invention are as follows：
The gas channel of the thermal vias for connecting two opposite side walls is constituted between two circuit board of the invention, two radiator fans turn
When dynamic, two heat exchange circulation are formed in a kind of electronic load instrument, two circuit boards can carry out comprehensive radiating, and radiating rate is fast, dissipates
Thermal effect is good.
Brief description of the drawings
Fig. 1 is a kind of module diagram of the better embodiment of electronic load instrument of the invention.
Fig. 2 is a kind of structural representation of the better embodiment of electronic load instrument of the invention.
Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described further：
Fig. 1 and Fig. 2 is referred to, the present invention relates to a kind of electronic load instrument, its better embodiment dissipates including housing 50, two
Hot-air fan 20, processor 40, the circuit board 70 of temperature sensor 10 and two.
Two radiator fans 20, processor 40, the circuit board 70 of temperature sensor 10 and two are mounted in the housing 50.The shell
The two opposite side walls of body 50 respectively open up the thermal vias of some uniform arrangements.One is constituted between two circuit boards 70 and connects two opposite sides
The gas channel of the thermal vias of wall, two radiator fans 20 are respectively positioned at two ends of the gas channel.
The temperature sensor 10 is used to detect the temperature in a kind of electronic load instrument, and generates corresponding temperature signal.
In the present embodiment, the temperature sensor 10 uses the temperature sensor of model PT100.
The processor 40 is used to compare the temperature signal of the temperature sensor 10 with default temperature threshold signal,
When temperature signal is more than temperature threshold signal, the processor 40 drives two radiator fans 20 to rotate, so that a kind of electronics
Two heat exchange circulation are formed in load meter, two circuit boards 70 can carry out comprehensive radiating, and radiating rate is fast, good heat dissipation effect.
When temperature signal is less than temperature threshold signal, the processor 40 stops driving two radiator fans 20, is beneficial to province
Electric energy-conservation.
In the present embodiment, the processor 40 is single-chip microcomputer.
For a person skilled in the art, technical scheme that can be as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the protection model that should all belong to the claims in the present invention
Within enclosing.
