Technical Field

[0001] The utility model belongs to the technical field of water cooling equipment, and in particular relates to an external water cooling device and a network analyzer provided with the device. Background Art

[0002] Currently, there is no external water cooling device designed specifically for water-cooled network analyzers. When using a water-cooled network analyzer, an external circulating pump is connected to the water tank to pump cooling water into the water inlet of the network analyzer. A water pipe is then used to guide the high-temperature cooling water flowing out of the water outlet of the network analyzer into the water tank. The circulating cooling water is used to take away the heat dissipated inside the network analyzer, thereby achieving the purpose of cooling the equipment.

[0003] The existing external water cooling device has the following shortcomings during use:

[0004] Since the water tank is open, the cooling water is easily contaminated by pollutants in the air and will deteriorate over time, requiring frequent replacement of the cooling water.

[0005] The ability to detect the working status of the external water cooling device is insufficient, and failures cannot be discovered and handled immediately.

[0006] There is no function to recycle the cooling water in the pipeline, resulting in that when the pipeline connection between the external water cooling device and the network analyzer is disconnected, the cooling water will flow out from the disconnection point, affecting the safety of surrounding equipment and polluting the environment.

[0007] The heat dissipation effect of the water tank is not good. After the device has been working for a long time, the temperature of the circulating cooling water will increase, resulting in a decrease in the cooling effect. Utility Model Content

[0033] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 3 As shown, an external water cooling device proposed by the utility model is used in a network analyzer as an example, and is introduced in detail from three aspects: product structure, assembly process and usage method.

[0035] 1. Product components and connection relationships:

[0036] This device mainly consists of:

[0037] The water tank is composed of a water tank 1, a water tank water filling pipe 2, a water tank drain pipe 3, a water tank outlet pipe 4, a water tank return pipe 5, a device outlet pipe 6, a device return pipe 7, a water level sensor 8, a temperature sensor 9, a pressure relief valve 10, a two-way water pump 11, a flow sensor 12, a fan 13, a radiator 14, a controller 15, and a casing 16.

[0045] The flow sensor 12 is used to detect the flow rate of cooling water in the pipeline;

[0046] The fan 13 is used to supply air to the radiator 14 for heat dissipation.

[0047] The S-shaped pipe of the radiator 14 is made of copper, and the heat sink is made of aluminum, which is used to dissipate the heat of the cooling water in the pipe into the air;

[0048] The controller 15 includes buttons, a display, and a speaker. The buttons can control the entire device, the display can display the operating status of the device, and the speaker can emit a sound to remind the abnormal status of the equipment;

[0049] The housing 16 is made of stainless steel and is used to fix the components thereon.

[0050] 2. Assembly process of this device:

[0051] Fix the water tank 1 to the corresponding position in the housing 16;

[0052] Fix one end of the flange of the water tank water supply pipe 2 to the housing 16, and connect the other end to the water tank 1;

[0053] Fix one end of the flange of the water tank drain pipe 3 to the housing 16, and connect the other end to the water tank 1;

[0054] Install the water level sensor 8 into the hole reserved in the water tank 1;

[0055] Install the temperature sensor 9 into the reserved hole of the water tank 1;

[0056] Connect one end of the water tank outlet pipe 4 to the water tank 1, and the other end to the interface of the two-way water pump 11;

[0057] Connect one end of the flow sensor 12 to the remaining interface of the bidirectional water pump 11;

[0058] Connect one end of the device outlet pipe 6 to the flow sensor 12, and fix the flange interface at the other end to the corresponding hole of the housing 16;

[0059] Fix the heat sink 14 to the corresponding position in the housing 16;

[0060] Fix two fans 13 to the radiator 14;

[0061] Connect one end of the water tank return pipe 5 to the water tank 1, and the other end to the radiator 14;

[0062] Connect one end of the device return pipe 7 to the radiator 14, and fix the flange interface at the other end to the corresponding hole of the shell 16;

[0063] Connect one end of the pressure relief valve 10 to the water tank 1, and fix the flange interface at the other end to the corresponding hole of the housing 16;

[0064] Fix the controller 15 to the corresponding square hole of the housing 16.

[0065] 3. Working process and principle:

[0066] Open the pressure relief valve 10, and inject cooling water into the water tank 1 through the flange of the water tank water pipe 2. At this time, the excess air in the water tank 1 will be discharged through the pressure relief valve 10. While injecting cooling water, pay attention to the water level display on the screen of the controller 15. When the water level display reaches 100%, stop injecting cooling water;

[0067] Connect the flange interface of the device water outlet pipe 6 to the water inlet on the network analyzer with a water pipe;

[0068] Connect the flange interface of the device return pipe 7 to the water outlet on the network analyzer with a water pipe;

[0069] Start the external water cooling device;

[0070] The two-way water pump 11 is started, and the cooling water in the water tank 1 passes through the water tank outlet pipe 4, the two-way water pump 11, the flow sensor 12, and the device outlet pipe 6 to reach the water inlet of the network analyzer, and then is transported to the inside of the network analyzer;

[0071] The cooling water passes through the heating module in the network analyzer, absorbs heat, increases in temperature, flows out from the water outlet of the network analyzer, passes through the device return pipe 7, and reaches the radiator 14;

[0072] The heat of the cooling water is transferred to the aluminum fins on the copper tubes through the copper tubes of the radiator 14. The fins dissipate the heat to the surrounding air, and the air absorbs the heat and the temperature rises.

[0073] The running fan 13 draws in cold air from the outside and blows away the hot air on the radiator, thereby cooling the radiator 14;

[0074] The cooled cooling water passes through the water tank return pipe 5 and returns to the water tank 1, completing a cycle.

[0075] In this way, the circulating cooling water is used to take away the heat emitted by the network analyzer during operation, and then the fan 13 and the radiator 14 are used to cool the cooling water, thereby achieving the purpose of heat dissipation and cooling of the network analyzer, and the thermal insulation equipment operates stably and healthily.

[0076] When it is necessary to disconnect the pipeline connection between the external water cooling device and the network analyzer, the two-way water pump 11 is operated in reverse, and the cooling water in the pipeline will be sucked into the water tank 1 by the water pump, so that the remaining cooling water in the pipeline will not flow out from the disconnected interface to pollute the environment and damage surrounding equipment.

[0077] As can be seen from the above content, since the utility model device is provided with a water level sensor 8, when a water circuit leaks, the amount of cooling water returned is less than the amount of cooling water that goes out, which will cause the water level in the water tank 1 to drop, thereby causing the controller to alarm. Since a flow sensor 12 is provided, when a two-way water pump 11 fails or a pipeline is blocked, the cooling water flow in the pipeline will change, thereby causing the controller to alarm. Since a temperature sensor 9 is provided, when a fan 13 fails, the cooling water temperature in the water tank will rise abnormally, thereby causing the controller to alarm. By providing a pressure relief valve 10, when the air pressure inside the water tank 1 increases due to the increase in cooling water temperature and evaporation, the pressure relief valve will automatically open to reduce the air pressure in the water tank 1.

[0078] Moreover, the device of the utility model has the function of recovering cooling water in the pipeline. When the device is applied to a network analyzer or other equipment with a cooling water heat dissipation pipeline, when the external water cooling device and the network analyzer / equipment are disconnected, the cooling water remaining in the pipeline will not flow out from the disconnected interface.

[0079] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
