Description

Technical Field

[0001] This utility model relates to the field of transmitter technology, specifically a single-crystal silicon pressure transmitter that facilitates heat dissipation. Background Technology

[0002] A single-crystal silicon pressure transmitter is an instrument used to measure the level, density, and pressure of liquids, gases, or vapors. Its working principle is to transmit the pressure through an isolation diaphragm and filling liquid to the silicon chip inside the sensor, causing a change in the resistance of the pressure sensor chip, which in turn causes a change in the output voltage of the detection system, thus achieving the measurement effect.

[0003] According to a public announcement of a high-efficiency heat dissipation structure for a single-crystal silicon pressure transmitter (Announcement No.: CN211784017U), the above application sets up a power chamber on the left side of the heat dissipation shell, and at the same time, a fan and an air inlet hood are set up inside the power chamber. This allows the air generated by the fan to enter the ventilation hole, and then the air flows in the ventilation hole to carry away the heat generated by the transmitter body during operation, thereby achieving the effect of heat dissipation for the transmitter body.

[0004] However, in actual use, although the above-mentioned equipment can dissipate heat from the transmitter body, the air conducts heat very poorly and is a poor conductor of heat, so the heat dissipation effect is limited. In view of this, we propose a single-crystal silicon pressure transmitter that is easy to dissipate heat. Utility Model Content

[0005] The purpose of this invention is to provide a single-crystal silicon pressure transmitter that facilitates heat dissipation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-crystal silicon pressure transmitter with easy heat dissipation, including a mounting frame, an assembly at the end of the mounting frame, a transmitter body detachably mounted on the outer wall of the assembly, a small cooling component detachably mounted on the inner wall of the assembly, a heat dissipation assembly on the outer wall of the assembly, the heat dissipation assembly including a first filter screen detachably mounted on the outer wall of the assembly, a second filter screen detachably mounted on the outer wall of the assembly, a filter plate detachably mounted on the outer wall of the assembly, a vent on the inner wall of the assembly, and an insertion groove on the inner wall of the assembly.

[0007] The motor is fixedly connected to the outer wall of the machine body. The output end of the motor is fixedly connected to a reciprocating threaded rod through the machine body. A threaded slider is threadedly connected to the outer wall of the reciprocating threaded rod. A limit plate is fixedly connected to the outer wall of the threaded slider. A mounting plate is fixedly connected to the outer wall of the threaded slider. A hinge sleeve is fixedly connected to the outer wall of the mounting plate. A copper plate is hinged to the outer wall of the hinge sleeve. A guide inclined plate is fixedly connected to the inner wall of the machine body.

[0008] Preferably, the outer wall of the copper plate is adapted to the inner wall of the insertion groove, so that the copper plate can be smoothly displaced on the inner wall of the insertion groove.

[0009] Preferably, two sets of guide ramps are provided, and the two sets of guide ramps are mirror images of the center plane of the machine body on both sides, so as to stably guide the copper plates on both sides.

[0010] Preferably, the number of vents is several, and the several vents are arranged in a circular array on the inner wall of the machine body.

[0011] Preferably, the outer wall of the limiting plate is provided with a pneumatic assembly, the pneumatic assembly includes a toothed column, the toothed column is rotatably mounted on the outer wall of the limiting plate, a rotating plate is fixedly connected to the outer wall of the toothed column, and a rack is fixedly connected to the inner wall of the machine body.

[0012] Preferably, the outer wall of the toothed column meshes with the outer wall of the rack, enabling smooth transmission.

[0013] Compared with the prior art, this utility model provides a single-crystal silicon pressure transmitter that facilitates heat dissipation, and has the following beneficial effects:

[0014] 1. This heat-dissipating single-crystal silicon pressure transmitter can activate a small cooling component and motor when heat dissipation is required. The small cooling component cools the transmitter, and the cool air diffuses to the vent for better cooling. The motor drives the reciprocating threaded rod to rotate, causing the limited threaded slider to move back and forth. This allows the copper plate inserted into the insertion slot to absorb heat to be displaced and cooled better. When the cooled copper plate is inserted into the insertion slot again, it continues to absorb heat from the surrounding area, further improving the cooling effect. When the copper plate is removed from the insertion slot, it tilts to both sides due to gravity, allowing for better cooling when unfolded. This ensures multiple and effective cooling methods when cooling the transmitter body.

[0015] 2. This heat-dissipating single-crystal silicon pressure transmitter allows the limited threaded slider to move back and forth, causing the toothed column of the meshing rack to rotate synchronously, which in turn drives the rotating plate to rotate. Ultimately, the rotating plate can agitate and mix the air in the path, allowing the air to be cooled better, thereby further improving the overall cooling effect and practicality.

[0024] like Figures 1-7 As shown, this utility model provides a technical solution: a single-crystal silicon pressure transmitter with easy heat dissipation, including a mounting frame 1, an organic body 2 at the end of the mounting frame 1, a transmitter body 3 detachably mounted on the outer wall of the organic body 2, a small cooling component 4 detachably mounted on the inner wall of the organic body 2, a heat dissipation component 5 on the outer wall of the organic body 2, the heat dissipation component 5 including a first filter screen 501, the first filter screen 501 detachably mounted on the outer wall of the organic body 2, a second filter screen 502 detachably mounted on the outer wall of the organic body 2, a filter plate 503 detachably mounted on the outer wall of the organic body 2, a vent 504 on the inner wall of the organic body 2, and an insertion groove 505 on the inner wall of the organic body 2.

[0025] Furthermore, the motor 506 is fixedly connected to the outer wall of the body 2. The output end of the motor 506 is fixedly connected to a reciprocating threaded rod 507 through the body 2. A threaded slider 508 is threadedly connected to the outer wall of the reciprocating threaded rod 507. A limit plate 509 is fixedly connected to the outer wall of the threaded slider 508. A mounting plate 510 is fixedly connected to the outer wall of the threaded slider 508. A hinge sleeve 511 is fixedly connected to the outer wall of the mounting plate 510. A copper plate 512 is hinged to the outer wall of the hinge sleeve 511. A guide inclined plate 513 is fixedly connected to the inner wall of the body 2.

[0026] In this embodiment of the present invention, the outer wall of the copper plate 512 is adapted to the inner wall of the insertion groove 505, so that the copper plate 512 can be smoothly displaced on the inner wall of the insertion groove 505. Two sets of guide inclined plates 513 are provided, and the two sets of guide inclined plates 513 are mirrored on both sides of the center plane of the body 2, so that the copper plates 512 on both sides can be smoothly guided. Several vents 504 are provided, and the several vents 504 are arranged in a circumferential array on the inner wall of the body 2.

[0027] Furthermore, the outer wall of the limiting plate 509 is provided with a pneumatic assembly 6, which includes a gear column 601. The gear column 601 is rotatably mounted on the outer wall of the limiting plate 509. A rotating plate 602 is fixedly connected to the outer wall of the gear column 601, and a rack 603 is fixedly connected to the inner wall of the body 2. The outer wall of the gear column 601 meshes with the outer wall of the rack 603, so that the transmission can be carried out smoothly.

[0028] In this invention, during daily use, the transmitter body 3 can be used to measure the level, density, and pressure of liquids, gases, or vapors. When heat dissipation is required, the small cooling component 4 and the motor 506 can be activated. At this time, the small cooling component 4 cools down, and the cold air diffuses to the vent 504 for better cooling. The motor 506 drives the reciprocating threaded rod 507 to rotate, thereby causing the threaded slider 508, which is limited, to move back and forth. This allows the copper plate 512, which is inserted into the insertion slot 505 to absorb heat, to be displaced and cooled down better. When the cooled copper plate 512 is inserted into the insertion slot 505, it continues to absorb heat from the surrounding area, thereby further improving the cooling effect. When the copper plate 512 is removed from the insertion slot 505, it tilts to both sides due to gravity, thus achieving better cooling when unfolded. This ensures multiple and effective cooling methods when cooling the transmitter body 3.

[0029] Furthermore, as the threaded slider 508, which is in a limited position, moves back and forth, the toothed column 601 of the meshing rack 603 rotates synchronously, thereby driving the rotating plate 602 to rotate. Ultimately, the rotating plate 602 can agitate and mix the air in the path, allowing the air to be cooled better, thus further improving the overall cooling effect and practicality.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
