Description

Technical Field

[0001] This utility model relates to the field of auxiliary heat dissipation technology, and in particular to an auxiliary heat dissipation mechanism for rubidium atomic clocks. Background Technology

[0002] A rubidium atomic clock is a timing instrument that uses the energy level transition characteristics of rubidium atoms to achieve high-precision time and frequency standards. It plays a vital role in many fields such as communication, navigation, and scientific research. A rubidium atomic clock generates a large amount of heat during stable operation.

[0003] Currently, although some rubidium atomic clocks are equipped with basic heat dissipation measures, such as simple air cooling, which uses a fan to drive airflow to remove heat, this method has limited heat dissipation efficiency and is difficult to meet heat dissipation requirements when high power is generated or the ambient temperature is high. Therefore, we propose an auxiliary heat dissipation mechanism for rubidium atomic clocks. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary heat dissipation mechanism for rubidium atomic clocks. This solves the technical problem that although some rubidium atomic clocks are equipped with basic heat dissipation measures, such as simple air cooling, which uses a fan to drive airflow to remove heat, this method has limited heat dissipation efficiency and is difficult to meet heat dissipation requirements when high power is generated or the ambient temperature is high.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An auxiliary heat dissipation mechanism for a rubidium atomic clock includes a rubidium atomic clock body. A heat dissipation mechanism is provided on one side of the rubidium atomic clock body. The heat dissipation mechanism includes a mounting frame, which is connected to the rubidium atomic clock body through threaded holes on both sides. A connecting frame is fixedly connected to one side of the mounting frame. An induced draft fan is fixedly installed in the middle of the interior of the connecting frame. A filter plate is inserted into the upper part of the interior of the connecting frame. A circulating cooling component is provided inside and on one side of the connecting frame.

[0009] Preferably, the circulating refrigeration assembly includes a water tank, which is installed on one side of the connecting frame. A refrigeration device is installed in the middle of one side of the water tank. A circulating water pump is fixedly installed at the upper end of the water tank. A cooling pipe is fixedly connected to one end of the circulating water pump, and the other end of the cooling pipe is connected through the water tank.

[0010] The technical effect of adopting the above-mentioned further solution is that the refrigeration device continuously cools the water inside the water tank, and then the water is drawn out by the circulating water pump and circulated through the cooling pipe, which can cool the air introduced by the induced draft fan.

[0011] Preferably, connecting plates are fixedly connected to both sides of the inner side of the mounting frame. Two pressure springs are fixedly connected to one side of the connecting plate, and a fixing plate is fixedly connected to the other end of the two pressure springs. A guide rod is fixedly connected to the middle of one side of the connecting plate, and the guide rod is slidably engaged with the fixing plate.

[0012] The technical effect of adopting the above-mentioned further solution is that, under the action of the restoring force of the pressure spring, it can ensure that the heat-conducting plate is always in close contact with the heat source on the back side of the rubidium atomic clock body, so as to transfer heat to the inside of the heat sink frame.

[0013] Preferably, a heat dissipation frame is fixedly connected between the fixed plates, and an inner plate is fixedly connected inside the heat dissipation frame. Multiple heat pipes are embedded inside the inner plate, and a heat-conducting plate is fixedly connected to one end of each heat pipe. The heat pipes are inclined upwards, with the bottom end of the heat pipe being the evaporation end and the top end being the condensation end. The heat pipes are not sealed, and a hydrated salt medium is provided inside the heat pipes.

[0014] The technical effect of adopting the above-mentioned further solution is as follows: At this time, the cold air blows towards the condensing end at the top of multiple heat pipes. Since the heat-conducting plate concentrates the heat generated by the rubidium atomic clock body at the evaporating end at the bottom of the heat pipe, the hydrated salt medium at the bottom of the heat pipe is heated and evaporates. In this process, it will absorb a large amount of heat. The gas medium after evaporation has a low density and will flow to the condensing end at the top of the heat pipe. Under the action of the cold air at the condensing end, it will be instantly cooled and liquefied into liquid, and then flow back to the evaporating end. This process is repeated to achieve efficient cooling of the rubidium atomic clock body.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting up a connecting plate, a pressure spring, a guide rod and a fixing plate, this utility model can ensure that the heat-conducting plate is always in close contact with the heat source on the back side of the rubidium atomic clock body under the action of the pressure spring's restoring force, thereby stably transferring heat to the inside of the heat dissipation frame.

[0018] 2. By setting up a circulating refrigeration component, this utility model can cool the air drawn in by the induced draft fan through the combined action of the water tank, refrigeration device, circulating water pump and cooling pipe, so as to cool down the condenser end of the heat pipe.

[0019] 3. This utility model uses a heat dissipation frame, a heat-conducting plate, an embedded plate, and a heat pipe. The heat-conducting plate concentrates the heat generated by the rubidium atomic clock body at the evaporation end of the heat pipe. The hydrated salt medium at the bottom of the heat pipe evaporates when heated, absorbing a large amount of heat in the process. The gaseous medium after evaporation has a low density and flows to the condensation end at the top of the heat pipe. Under the action of the cold air at the condensation end, it is instantly cooled and liquefied into a liquid, and then flows back to the evaporation end. This process is repeated to achieve efficient cooling of the rubidium atomic clock body. Attached Figure Description

[0026] This application provides an auxiliary heat dissipation mechanism for a rubidium atomic clock. By setting a connecting plate, a pressure spring, a guide rod, and a fixing plate, the heat-conducting plate can be kept in close contact with the heat source on the back side of the rubidium atomic clock body under the action of the pressure spring's restoring force. This allows for the stable transfer of heat to the interior of the heat dissipation frame. By setting a circulating cooling component, the air drawn in by the exhaust fan can be cooled in conjunction with the water tank, cooling device, circulating water pump, and cooling pipe, so as to cool the condenser end of the heat pipe. By setting up the heat dissipation frame, heat-conducting plate, embedded plate, and heat pipe, the heat-conducting plate concentrates the heat generated by the rubidium atomic clock body at the evaporation end of the heat pipe. The hydrated salt medium at the bottom of the heat pipe evaporates when heated, absorbing a large amount of heat in the process. The evaporated gas medium has a low density and flows to the condenser end at the top of the heat pipe. Under the action of the cold air at the condenser end, it is instantly cooled and liquefied into liquid, and then flows back to the evaporation end. This process is repeated to achieve efficient cooling of the rubidium atomic clock body.

[0027] Example 1

[0028] The technical solution in this application embodiment effectively addresses the problem that although some rubidium atomic clocks are equipped with basic heat dissipation measures, such as simple air cooling, which uses a fan to drive airflow to remove heat, this method has limited heat dissipation efficiency and is difficult to meet heat dissipation requirements when high power generation or high ambient temperature is required. The overall approach is as follows:

[0029] like Figures 1 to 4 To address the problems existing in the prior art, this utility model provides an auxiliary heat dissipation mechanism for a rubidium atomic clock, including a rubidium atomic clock body 1. A heat dissipation mechanism 2 is provided on one side of the rubidium atomic clock body 1. The heat dissipation mechanism 2 includes a mounting frame 21, which is connected to the rubidium atomic clock body 1 through threaded holes on both sides. A connecting frame 22 is fixedly connected to one side of the mounting frame 21. An induced draft fan 24 is fixedly installed in the middle of the interior of the connecting frame 22. A filter plate 25 is inserted into the upper part of the interior of the connecting frame 22. A circulating cooling component 23 is provided inside and on one side of the connecting frame 22. The circulating cooling component 23 includes a water tank 231, which is installed on one side of the connecting frame 22. A cooling device 232 is installed in the middle of one side of the water tank 231. A circulating water pump 233 is fixedly installed at the upper end of the water tank 231. A cooling pipe 234 is fixedly connected to one end of the circulating water pump 233, and the other end of the cooling pipe 234 is connected through the water tank 231.

[0030] By adopting the above technical solution, when the rubidium atomic clock body 1 is cooled, the induced draft fan 24 blows the outside air into the mounting frame 21 after it is filtered by the filter plate 25. At the same time, the cooling device 232 continuously cools the water in the water tank 231. After being drawn out by the circulating water pump 233 and circulated through the cooling pipe 234, the air introduced by the induced draft fan 24 can be cooled. At this time, the cold air is blown towards the condenser end at the top of the multiple heat pipes 218.

[0031] Example 2

[0032] like Figures 1 to 4 The mounting frame 21 has connecting plates 211 fixedly connected to both sides of its interior. Two pressure springs 212 are fixedly connected to one side of the connecting plate 211, and a fixing plate 214 is fixedly connected to the other end of the two pressure springs 212. A guide rod 213 is fixedly connected to the middle of one side of the connecting plate 211, and the guide rod 213 is slidably engaged with the fixing plate 214. A heat dissipation frame 215 is fixedly connected between the fixing plates 214. An inner plate 217 is fixedly connected inside the heat dissipation frame 215. Multiple heat pipes 218 are embedded inside the inner plate 217. A heat-conducting plate 216 is fixedly connected to one end of each heat pipe 218. The heat pipes 218 are inclined upwards, with the bottom end of the heat pipe 218 being the evaporation end and the top end being the condensation end. The heat pipes 218 are not sealed, and a hydrated salt medium is provided inside the heat pipes 218.

[0033] By adopting the above technical solution, the device is connected to the rubidium atomic clock body 1 via the mounting frame 21. During the installation process, the mounting frame 21 continuously moves closer to the rubidium atomic clock body 1, and the heat-conducting plate 216 corresponds to and is in close contact with the heat source on the back side of the rubidium atomic clock body 1. At this time, the pressure spring 212 is compressed. Under the action of the restoring force of the pressure spring 212, it can be ensured that the heat-conducting plate 216 is always in close contact with the heat source on the back side of the rubidium atomic clock body 1, thereby transferring heat to the interior of the heat dissipation frame 215. The cold air blows towards the condenser end at the top of multiple heat pipes 218. Since the heat conduction plate 216 concentrates the heat generated by the rubidium atomic clock body 1 at the evaporation end at the bottom of the heat pipe 218, the hydrated salt medium at the bottom of the heat pipe 218 evaporates when heated. In this process, it absorbs a large amount of heat. The gas medium after evaporation has a low density and flows to the condenser end at the top of the heat pipe 218. Under the action of the cold air at the condenser end, it is instantly cooled and liquefied into a liquid, and then flows back to the evaporation end. This process is repeated to achieve efficient cooling of the rubidium atomic clock body 1.

[0034] Working Principle: In use, the device is connected to the rubidium atomic clock body 1 via the mounting frame 21. During installation, the mounting frame 21 continuously moves closer to the rubidium atomic clock body 1, and the heat-conducting plate 216 corresponds to and is in close contact with the heat source on the back side of the rubidium atomic clock body 1. At this time, the pressure spring 212 is compressed. Under the action of the restoring force of the pressure spring 212, the heat-conducting plate 216 is kept in close contact with the heat source on the back side of the rubidium atomic clock body 1, thereby transferring heat to the interior of the heat dissipation frame 215. When dissipating heat from the rubidium atomic clock body 1, the exhaust fan 24 blows outside air into the mounting frame 21 after filtering it through the filter plate 25. At the same time, the cooling device 232 continuously cools the inside of the rubidium atomic clock body 1. The water inside the water tank 231 is cooled and then drawn out by the circulating water pump 233 and circulated through the cooling pipe 234 to cool the air introduced by the fan 24. At this time, the cold air is blown towards the condenser end of the top of multiple heat pipes 218. Since the heat conduction plate 216 concentrates the heat generated by the rubidium atomic clock body 1 at the evaporation end of the bottom of the heat pipe 218, the hydrated salt medium at the bottom of the heat pipe 218 evaporates when heated. In this process, a large amount of heat is absorbed. The gas medium after evaporation has a low density and flows to the condenser end of the top of the heat pipe 218. Under the action of the cold air at the condenser end, it is instantly cooled and liquefied into liquid, and then flows back to the evaporation end. This process is repeated to achieve efficient cooling of the rubidium atomic clock body 1.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
