Abstract
An electronic load instrument comprises a housing, two heat radiating fans, a processor, a temperature sensor and two circuit boards. The two heat radiating fans, the processor, the temperature sensor and the two circuit boards are respectively arranged in the housing. Two opposite side walls of the housing are respectively provided with a plurality of uniformly arranged heat radiating through holes. An air flow channel for communicating the heat radiating through holes of the two opposite side walls is formed between the two circuit boards. The two heat radiating fans are respectively provided at two ends of the air flow channel. The temperature sensor is used for detecting the temperature in the electronic load instrument and generates a corresponding temperature signal. The processor is used for comparing the temperature signal of the temperature sensor with a preset temperature threshold signal. When the temperature signal is larger than the temperature threshold signal, the processor drives the two heat radiating fans to rotate; and when the temperature signal is smaller than the temperature threshold signal, the processor stops driving to the two heat radiating fans. The electronic load instrument provided by the utility model has a good heat radiating effect.

Background technology
Electronic load instrument is the electronic equipment for testing power supply parameter.Electronic load instrument comprises metal shell and is installed on each components and parts in housing.On the housing of existing electronic load instrument, offer some louvres, with the heat that each components and parts are produced, dispel the heat, this kind of radiating mode radiating effect is not good, if electronic load instrument is positioned over the poor place that ventilates, the internal temperature of electronic load instrument raises fast, cannot rationally dispel the heat to internal component, easily make the test result of electronic load instrument occur error, even make electronic load instrument to work.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of electronic load instrument, its rapid heat dissipation, excellent in heat dissipation effect.
For achieving the above object, the utility model adopts following technical scheme:
An instrument, it comprises housing, two radiator fans, processor, temperature sensor and two circuit boards; Two radiator fans, processor, temperature sensor and two circuit boards are all installed in this housing; The two opposite side walls of this housing is respectively offered some heat radiation through holes of evenly arranging; Between two circuit boards, form the gas channel of the heat radiation through hole of a connection two opposite side walls, two radiator fans lay respectively at two ends of this gas channel; This temperature sensor is for detection of the temperature in this electronic load instrument, and generates corresponding temperature signal; This processor is for the temperature signal of this temperature sensor and default temperature threshold signal are compared, and when temperature signal is greater than temperature threshold signal, this processor drives two radiator fans rotations; When temperature signal is less than temperature threshold signal, this processor stops driving two radiator fans.
Further, this temperature sensor adopts the temperature sensor that model is PT100.
Further, this processor is single-chip microcomputer.
The beneficial effects of the utility model are as follows:
Between two circuit boards of the present utility model, form the gas channel of the heat radiation through hole of a connection two opposite side walls, when two radiator fans rotate, form two heat exchange circulation in electronic load instrument, two circuit boards can carry out comprehensive heat radiation, and radiating rate is fast, good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is the module diagram of the better embodiment of the utility model electronic load instrument.
Fig. 2 is the structural representation of the better embodiment of the utility model electronic load instrument.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1 and Fig. 2, the utility model relates to a kind of electronic load instrument, and its better embodiment comprises housing 50, two radiator fans 20, processor 40, temperature sensor 10 and two circuit boards 70.
Two radiator fans 20, processor 40, temperature sensor 10 and two circuit boards 70 are all installed in this housing 50.The two opposite side walls of this housing 50 is respectively offered some heat radiation through holes of evenly arranging.Between two circuit boards 70, form the gas channel of the heat radiation through hole of a connection two opposite side walls, two radiator fans 20 lay respectively at two ends of this gas channel.
This temperature sensor 10 is for detection of the temperature in this electronic load instrument, and generates corresponding temperature signal.In the present embodiment, this temperature sensor 10 adopts the temperature sensor that model is PT100.
This processor 40 is for comparing the temperature signal of this temperature sensor 10 and default temperature threshold signal, when temperature signal is greater than temperature threshold signal, this processor 40 drives two radiator fans 20 to rotate, thereby make formation two heat exchange circulation in electronic load instrument, two circuit boards 70 can carry out comprehensive heat radiation, radiating rate is fast, good heat dissipation effect.
When temperature signal is less than temperature threshold signal, this processor 40 stops driving two radiator fans 20, is beneficial to power and energy saving.
In the present embodiment, this processor 40 is single-chip microcomputer.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection range of the utility model claim within.
