Description

Technical Field

[0001] The utility model relates to the technical field of a temperature transmitter dustproof housing with a guide and heat dissipation structure, in particular to a temperature transmitter dustproof housing with a guide and heat dissipation structure. Background Art

[0002] A temperature transmitter is a device that converts temperature measurements into a standardized output signal. It is widely used to measure and control temperature parameters in industrial processes. It typically consists of a sensor (such as a thermocouple or RTD) and a signal converter. It can output standard electrical signals such as 4-20mA or 0-10V, and may also include digital signal output capabilities such as RS485. Temperature transmitter performance indicators include accuracy, response time, and operating environment. It is suitable for a variety of industries, including petroleum, chemical, electric power, and metallurgy.

[0003] To improve the device's heat dissipation efficiency and stability. Electronic devices operating in high-temperature environments generate significant heat. Failure to effectively dissipate heat can lead to performance degradation or even damage. The heat dissipation structure can help better guide and disperse heat, maintaining a stable internal temperature, thereby extending the device's lifespan and ensuring its accuracy and reliability.

[0004] According to the description on the patent website of a temperature transmitter with a diversion and heat dissipation structure (authorization publication number: CN213956587U), "The present utility model discloses a temperature transmitter with a diversion and heat dissipation structure, comprising a protective housing, a spiral blade, and a fan blade. The top of the protective housing is fixedly connected to a protective cover, the middle portion of the upper surface of the protective cover is fixedly connected to a motor cover, a heat dissipation net is provided on one side of the motor wall, and a motor is provided inside the motor cover. The present utility model is provided with a first gear, a second gear, and a spiral blade. When the motor is working, the motor drives the first gear to rotate via the first rotating rod, the first gear drives the second gear to rotate, and the second gear drives the spiral blade to rotate via the limiting ring provided inside the second gear. When the spiral blade rotates, airflow is generated, allowing external air to enter the interior of the device through the collar. When the temperature of an object is measured, the spiral blade brings air on the surface of the measured object into the device, reducing the temperature fluctuation caused by the contact between the temperature guide rod and the air, reducing experimental errors, and improving the measurement accuracy of the device."

[0005] In view of the above-mentioned related technologies, the inventors believe that it is not possible to effectively cool the electronic components in the shell. The cooling process is achieved only by exchanging external gas with internal gas, and the cooling effect is not ideal. If the equipment works in a high-temperature environment, the temperature difference between the internal and external gases is small during gas exchange, and the cooling effect is not ideal, or even no cooling effect. Therefore, it is urgent to improve a temperature transmitter shell with a diversion and heat dissipation structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] See also Figure 1-Figure 5The utility model provides a technical solution: a dust-proof housing for a temperature transmitter with a diversion and heat dissipation structure, comprising a temperature measuring rod 1, a fastener 2 being fixedly installed in the middle part of the temperature measuring rod 1, a fastener 2 being provided on the top of the temperature measuring rod 1, an upper end of the fastener 2 being movably installed directly below the housing 4, an incoming wire box 5 being fixedly installed above the entire top of the housing 4, a front end cover 6 being movably installed directly in front of the housing 4, a rear end cover 8 being movably installed behind the housing 4, a cavity being provided in the housing 4 for facilitating the installation of a temperature-changing component, a diversion and heat dissipation device and a temperature-changing component being provided in the housing, the diversion and heat dissipation device comprising a water cooling mechanism and an air cooling mechanism, and a plurality of ventilation holes 9 being regularly provided on the rear end cover 8.

[0027] The temperature-changing component includes a circuit board base 204 . The circuit board base 204 is fixedly mounted on the inner side of the housing 4 . The circuit board 10 is fixedly mounted on one side of the circuit board base 204 . The circuit board base 204 is an aluminum base with good thermal conductivity.

[0028] The diversion heat dissipation device includes a water cooling mechanism, which includes a radiator 201. A water pump 202 is fixedly installed above the radiator 201. The water pump 202 is fixedly installed on the other side of the circuit board base 204. A water-cooled heat dissipation copper tube 203 is fixedly installed on the water pump. The water-cooled heat dissipation copper tube 203 is close to the circuit board base 204.

[0029] A cooling fan 205 is provided in the radiator 201 . The cooling fan is fixedly mounted on the output shaft of the motor 206 . A plurality of cooling fins 207 are fixedly mounted on the radiator 201 .

[0030] The temperature measuring rod 1 is in contact with the source to be detected, and generates corresponding electrical signals according to the temperature change of the source to be detected. These electrical signals are transmitted to the circuit board 10, and the temperature signals are converted into standard electrical signals for output through various electronic components on the circuit board 10, which is convenient for remote observation and control. At this time, the electronic components on the circuit board 10 are always in working state, so a lot of heat will be generated. If these electronic components are not cooled in time, the service life of the equipment may be affected. Therefore, it is necessary to cool them down to improve the stability of the equipment in high temperature environment and extend the service life of the equipment. At this time, the heat dissipation device in the shell starts to work, and the motor 2 located inside the radiator 201 06 starts and drives the cooling fan 205 located on the output shaft of the motor 206 to start working, and the water pump 202 starts working to keep the cooling liquid in the water-cooled heat dissipation copper tube 203 flowing, and the cooling fan 205 cools the heat sink 207. The heat dissipation copper tube is located through the heat sink 207. Since the water-cooled heat dissipation copper tube 203 is close to the base of the circuit board, the flowing cooling liquid will take away the heat and then conduct the heat to the heat sink 207. Under the action of the cooling fan 205, the heat sink is cooled and the cooling liquid in the water-cooled heat dissipation copper tube 203 is cooled, thereby cooling the base of the circuit board and then cooling the electronic components located on the circuit board 10.

[0033] The water-cooled copper tubes 203 and the air-cooled copper tubes 208 are both fixedly passed through the plurality of heat sinks.

[0034] The heat dissipation device also uses an air-cooled radiator, and the air-cooled heat dissipation copper tube 208 located in the heat sink 207 also starts to work to achieve cooling treatment together, and the excess heat will be discharged from the ventilation hole 9.
