Electronic load meter

Abstract

The invention discloses an electronic load meter. The electronic load meter comprises a casing, two radiating fans, a processor, a temperature sensor and two circuit boards; the two radiating fans, the processor, the temperature sensor and the two circuit boards are all mounted in the casing; a plurality of uniformly arranged radiating through holes are formed in both two relative side walls of the casing; an air flow channel which is communicated with the radiating through holes in the two relative side walls is formed between the two circuit boards, and the two radiating fans are respectively located at two tail ends of the air flow channel; the temperature sensor is used for detecting the temperature inside the electronic load meter, and generating a corresponding temperature signal; the processor is used for comparing the temperature signal of the temperature sensor with a preset temperature threshold signal, the processor drives the two radiating fans to rotate when the temperature signal is greater than the temperature threshold signal, and the processor stops driving the two radiating fans when the temperature signal is smaller than the temperature threshold signal. Furthermore, the electronic load meter disclosed by the invention is good in radiating effect.

Description

Technical field [0001] The invention relates to an electronic load instrument. Background technique [0002] An electronic load meter is an electronic device used to test power supply parameters. An electronic load instrument includes a metal shell and various components installed in the shell. A number of heat dissipation holes are provided on the shell of an existing electronic load device to dissipate the heat generated by each component. This heat dissipation method has a poor heat dissipation effect. If an electronic load device is placed in a poorly ventilated place, The internal temperature of an electronic load device rises quickly, and the internal components cannot be reasonably dissipated, which easily causes errors in the test results of an electronic load device, and even makes an electronic load device unable to work normally. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an electr...

AI Technical Summary

Problems solved by technology

The housing of an existing electronic load has several heat dissipation holes to dissipate the heat generated by each component. This heat dissipation method has poor heat dissipation effect. If an electronic load is placed in a poorly ventilated place, The internal temperature of an electronic load rises rapidly, and it is impossible to properly dissipate heat from the internal components, which may easily cause errors in the test results of an electronic load, and even cause an electronic load to fail to work normally.
