Description

Technical Field

[0001] This invention relates to the field of railway signaling equipment technology, specifically to a temperature control device for railway signaling equipment. Background Technology

[0002] As the "nerve center" of the railway transportation system, the stable operation of railway signaling equipment directly determines railway traffic safety and transportation efficiency. These devices are mostly installed outdoors, enduring complex conditions such as alternating high and low temperatures, rain and snow, and dust accumulation. In actual operation, the signaling equipment continuously generates heat. If this heat cannot be dissipated in time, the internal temperature will rise, causing minor issues like equipment malfunctions and response delays, or even serious problems like component burnout and equipment failure, ultimately leading to railway transportation dispatching failures. Currently, traditional temperature control solutions for railway signaling equipment on the market have many limitations: some devices rely solely on natural heat dissipation, using ventilation holes in the equipment casing to expel heat, but natural heat dissipation is inefficient and cannot meet cooling requirements during high-temperature seasons or when the equipment is under high load; some devices have added active heat dissipation components such as cooling fans, but the heat dissipation structure is not effectively isolated from the equipment body, allowing rainwater, moisture, and dust to easily penetrate the equipment through the ventilation holes, causing precision components to short-circuit due to moisture, or malfunction due to dust accumulation, significantly shortening the equipment's service life.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Please see Figures 1-6 This application provides a new technical solution: a temperature control device for railway signal equipment, including a signal equipment body 1 and a cover 2. The cover 2 is fitted on top of the signal equipment body 1. A partition 3 is provided inside the cover 2 to divide the inside of the cover 2 into upper and lower parts. The signal equipment body 1 is located in the lower part of the cover 2. At least one set of temperature control mechanisms 4 is provided in the upper part of the cover 2. The partition 3 has a connecting hole 31, which is used to connect the upper and lower parts inside the housing 2. The temperature control mechanism 4 is located above the connecting hole 31 on the partition 3 and is used to remove the heat generated by the signal equipment body 1 in the lower part of the housing 2 when it is working.

[0024] The outer side of the housing 2 is provided with a heat dissipation vent 21 and an air inlet 22. Both the heat dissipation vent 21 and the air inlet 22 are connected to the upper inner part of the housing 2. At least two sets of heat dissipation vents 21 are provided. The two sets of heat dissipation vents 21 are connected to both sides of the temperature control mechanism 4, and are used to discharge the heat generated by the signal equipment body 1 to the outside of the housing 2 through the temperature control mechanism 4. The air inlet 22 allows the outside air of the housing 2 to enter the upper inner part of the housing 2.

[0025] In this embodiment, the housing 2 is made of stainless steel or plastic, and its size is customized according to the size of the signal equipment it covers. Its outer side is coated with a reflective coating.

[0026] When in use, when the signal equipment body 1 generates heat during operation, the heat enters the upper part of the housing 2 through the connecting hole 31 on the partition 3; the temperature control mechanism 4 is located above the connecting hole 31 and can absorb and conduct the heat entering the upper part; at the same time, outside air enters the upper part of the housing 2 through the air inlet 22 on the outside of the housing 2, forming an airflow circulation, the temperature control mechanism 4 transfers heat to the airflow, and finally the hot airflow is discharged outside the housing 2 through the heat dissipation vent 21 on the outside of the housing 2, thereby cooling the signal equipment body 1.

[0027] The upper cavity is physically isolated from the equipment area (lower cavity) by a heat dissipation channel. Both the heat dissipation vents and air inlets are located outside the equipment area, effectively preventing external dust, moisture, and rainwater from directly invading the precision signal equipment through the heat dissipation holes, greatly improving the reliability and lifespan of the equipment.

[0028] In this embodiment, as a preferred option, the temperature control mechanism 4 is configured as two sets, with the connecting holes 31 and heat dissipation vents 21 corresponding to the temperature control mechanism 4. Two sets of temperature control mechanisms 4 are provided, and the number and position of the connecting holes 31 and heat dissipation vents 21 correspond to the temperature control mechanism 4. The heat generated by the signal device body 1 enters the two sets of temperature control mechanisms 4 through the corresponding connecting holes 31, and each set of temperature control mechanisms 4 independently discharges the heat through the corresponding heat dissipation vent 21, forming a dual-path heat dissipation channel. The dual-path heat dissipation channel improves heat dissipation efficiency and is suitable for signal devices with high power and high heat generation. Simultaneously, the two sets of temperature control mechanisms can serve as backups for each other; if one set fails, the other set can still operate normally, improving the reliability of the device. In some embodiments, the temperature control mechanism 4 includes a heat-conducting end 41 and a heat-dissipating end 42. The upper side of the heat-conducting end 41 is connected to the lower end of the heat-dissipating end 42, and the lower side of the heat-conducting end 41 is connected to the lower part of the outer casing 2 through a connecting hole 31. The lower side of the heat-conducting end 41 is connected to the lower part of the casing 2 through the connecting hole 31, which can absorb the heat generated by the signal device body 1. The upper side of the heat-conducting end 41 is connected to the lower end of the heat-dissipating end 42, which transfers the absorbed heat to the heat-dissipating end 42. The heat-dissipating end 42 then dissipates the heat into the airflow in the upper part of the casing 2, and finally discharges it through the heat dissipation port 21.

[0029] In some embodiments, the heat-conducting end 41 includes a heat-conducting pipe 411, the lower end of which is connected to a plurality of connecting pipes 412. The connecting pipes 412 are respectively disposed above the connecting holes 31, with the connecting holes 31 corresponding to the connecting pipes 412. An opening 413 is formed on the upper side of the heat-conducting pipe 411, and the opening 413 communicates with the heat dissipation end 42. The plurality of connecting pipes 412 increases the heat absorption area and improves the efficiency of heat entering the heat-conducting end from the lower part of the casing.

[0030] In this embodiment, as a preferred option, there are three connecting pipes 412, and three corresponding connecting holes 31 are opened on the partition 3. The multi-channel design reduces the heat load of a single channel and reduces the risk of heat blockage.

[0031] In some embodiments, the heat dissipation end 42 includes a heat dissipation pipe 421, which is rectangular and hollow. Both ends of the heat dissipation pipe 421 are connected to heat dissipation ports 21, and the lower end of the heat dissipation pipe 421 is connected to the heat conduction end 41 through an opening. Heat transferred by the heat conduction end 41 enters the interior of the rectangular hollow heat dissipation pipe 421, diffuses within the heat dissipation pipe 421, and is then discharged outside the casing 2 through the heat dissipation ports 21 connected at both ends of the heat dissipation pipe 421.

[0032] In some embodiments, a heat sink 422 is disposed inside the heat pipe 421. The heat sink 422 is used to absorb the heat generated by the signal device body 1. A cooling fan 423 is provided with an opening on the upper side of the heat pipe 421 to blow air onto the heat sink 421, so that the heat on the heat sink 422 is discharged through the heat dissipation ports 21 connecting both sides of the heat pipe 421. After the cooling fan 423 with the opening on the upper side of the heat pipe 421 is started, it blows air onto the heat sink 422, accelerates the airflow, and carries away the heat on the heat sink 422 with the airflow, and finally discharges it from the casing 2 through the heat dissipation ports 21 connecting both sides of the heat pipe 421. The heat sink increases the heat dissipation area, and the cooling fan accelerates the airflow circulation. The combination of the two greatly improves the heat dissipation efficiency and can quickly reduce the temperature inside the heat pipe.

[0033] In this embodiment, as a preferred embodiment, a controller is provided on the upper side of the partition 3 to control the cooling fan 423. A temperature sensor is provided on the lower part of the outer cover 2, and the controller controls the cooling fan 423 based on the temperature sensing data. The temperature sensor is installed on the lower part of the cover 2 to detect the temperature around the signal device body 1 in real time and transmit the temperature data to the controller on the upper side of the partition 3. The controller presets a temperature threshold. When the detected temperature is higher than the threshold, the controller issues a command to start the cooling fan 423 and can adjust the cooling fan speed according to the temperature. When the temperature is lower than the threshold, the controller controls the cooling fan to stop working, realizing intelligent temperature control.

[0034] In some embodiments, the heat dissipation vent 21 and the air inlet 22 are arranged in a downwardly inclined arc shape, and filters are provided at the ends of the heat dissipation vent 21 and the air inlet 22. The downwardly inclined arc shape of the heat dissipation vent 21 and the air inlet 22 prevents external rainwater, dust, and other impurities from easily entering the housing 2 due to gravity. Simultaneously, the filters at the ends of both further filter dust and debris from the air, preventing them from entering the housing 2 and contaminating the signal equipment body 1 or blocking the heat dissipation channels. Hot air can still be smoothly discharged through the inclined heat dissipation vent 21, and cold air from the outside enters the housing through the inclined air inlet 22. This dual protection improves the cleanliness inside the housing and reduces the risk of equipment failure. The inclined structure does not affect airflow, ensuring heat dissipation and air intake efficiency, and balancing protection and heat dissipation functions.

[0035] In some embodiments, the top of the outer cover 2 is provided with a top cover 23. In daily use, the top cover 23 can prevent rainwater, falling objects from heights, dust and other substances from directly entering the interior of the cover 2; when it is necessary to repair or replace components such as the temperature control mechanism 4 in the upper part of the cover 2, the top cover 23 can be opened to facilitate maintenance work by operators.

[0036] Working principle: When a railway signal equipment temperature control device is in use, the signal equipment body 1 generates heat during operation, which heats the surrounding air. The hot air rises naturally due to its lower density and enters the upper part of the cover 2 through the connecting hole 31 on the partition 3. The heat-conducting end 41 of the temperature control mechanism 4, located above the connecting hole 31, effectively captures the hot air and the heat it carries. After the heat is absorbed by the heat-conducting end 41, it is transferred to the heat dissipation pipe 421 and the heat sink 422 inside the heat dissipation end 42 through heat conduction. The large surface area of ​​the heat sink 422 allows the heat to be rapidly diffused. After the heat dissipation fan 423, which is set on the upper opening of the heat dissipation pipe 421, is started, it blows air onto the heat sink 422, accelerating the airflow and causing the heat on the heat sink 422 to be carried away by the airflow. Finally, it is discharged from the cover 2 through the heat dissipation port 21 connected on both sides of the heat dissipation pipe 421.
