Description

Technical Field

[0001] The utility model relates to the technical field of electronic instruments, in particular to an oscilloscope with efficient heat dissipation. Background Art

[0002] An oscilloscope is a very widely used electronic measuring instrument. The oscilloscope uses a narrow electron beam composed of high-speed electrons to hit the screen coated with fluorescent substances, and small light spots can be generated, turning the invisible electrical signal into a visible image, which is convenient for people to study the change process of various electrical phenomena. At present, oscilloscopes are mainly used to measure voltage, current, frequency, phase, and modulation amplitude, etc.

[0003] During the use of the oscilloscope, the internal circuit components are in a closed environment, and the heat generated by the operation of the circuit components gradually accumulates, causing the temperature inside the oscilloscope to gradually rise. High temperature will cause the measurement accuracy of the device to decrease and shorten the service life. In order to solve the defects of the existing technology, the existing oscilloscopes are provided with heat dissipation holes on the outer shell to achieve heat dissipation of the oscilloscope. However, with long-term operation, dust is likely to accumulate on the heat dissipation holes, which will cause blockage of the heat dissipation holes, making the oscilloscope unable to dissipate heat and cool down again.

[0004] Therefore, it is urgent to research and develop an oscilloscope with efficient heat dissipation effect to solve the defects in the existing technology. Summary of the Invention

The oscilloscope main body 200 is arranged in the installation cavity 120, and there is a gap between the outer peripheral wall of the oscilloscope main body 200 and the inner peripheral wall of the installation cavity 120;

[0041] Air inlets 110 communicating with the installation cavity 120 are provided on both sides of the dust-proof housing 100. A dust-proof net 170 covering the air inlets 110 is provided on the inner wall of the dust-proof housing 100. A heat dissipation fan 300 is provided between each dust-proof net 170 and the oscilloscope main body 200. A number of heat dissipation holes 150 are provided on the outer peripheral wall of the oscilloscope main body 200;

[0042] A heat exchange component 400 is provided in the installation cavity 120. The heat exchange component 400 is located between the heat dissipation fan 300 and the oscilloscope main body 200, and the heat exchange end of each heat exchange component 400 is in contact with the outer wall of the oscilloscope main body 200.

[0043] In some embodiments, the heat exchange component 400 includes a first cold water tank 410, a second cold water tank 420, a first heat exchange tube 430, a second heat exchange tube 440, and a temperature sensor 470. Either the first cold water tank 410 or the second cold water tank 420 is provided at the top of the installation cavity 120, and the other is provided at the bottom of the installation cavity 120. The first heat exchange tube 430 and the second heat exchange tube 440 arranged side by side are provided between the first cold water tank 410 and the second cold water tank 420. The first heat exchange tube 430 and the second heat exchange tube 440 are both in contact with the outer wall of the oscilloscope main body 200, and the temperature sensor 470 is provided in the first cold water tank 410 and the second cold water tank 420.

[0044] By adopting the structure of a cold water tank in cooperation with a heat exchange tube and a temperature sensor 470 to achieve the heat dissipation of the oscilloscope main body 200, combined with the heat dissipation fans 300 arranged on both sides of the oscilloscope main body 200, the heat dissipation effect and heat dissipation controllability of the oscilloscope main body 200 are further improved.

Until all the water in the first cold water tank 410 or the second cold water tank 420 located at the top has entered the second cold water tank 420 or the first cold water tank 410 located at the bottom, the heat exchange component 400 on that side stops operating, the heat exchange component 400 on the other side is started, and the operating modes of the heat dissipation fans 300 on both sides are swapped.
