Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to a closed cabinet heat dissipation structure. Background Technology

[0002] A server rack is a cabinet structure used to centrally install, protect, manage, and house various electronic devices, electrical equipment, or related components. It is usually composed of a frame, side panels, door panels, top panel, bottom panel, and various accessories. A closed server rack, on the other hand, does not have pre-reserved ventilation openings and is completely enclosed inside. The heat dissipation structure of a closed server rack usually utilizes the heat conduction method of the various external side panels of the rack itself for heat dissipation.

In hot weather, the internal parts are prone to accelerated aging due to high temperature, thereby reducing the service life of the parts or causing damage to the parts. Utility Model Content

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] As described in the background art, in hot weather, internal parts are prone to accelerated aging due to high temperatures, thereby reducing the service life of the parts or causing damage to the parts. Example

[0032] Please refer to Figure 1 - Figure 6 A closed cabinet heat dissipation structure includes a housing 1, a control panel 11 fixedly connected to the upper end of the housing 1, and an electronic component 12 fixedly connected inside the end of the housing 1 near the control panel 11. A heat dissipation component is provided on the side of the electronic component 12 away from the control panel 11.

[0033] The heat dissipation assembly includes a first heat-conducting plate 21 fixedly connected to the end of the electronic component 12 away from the control panel 11, and a second heat-conducting plate 22 fixedly connected to the upper end of the side of the first heat-conducting plate 21 away from the electronic component 12. The end of the second heat-conducting plate 22 away from the first heat-conducting plate 21 is disposed through the casing 1. The heat at the electronic component 12 can be absorbed and conducted by the first heat-conducting plate 21 and the second heat-conducting plate 22.

[0034] Preferred, such as Figure 4 As shown, a water tank 23 is provided on the outer side of the second heat-conducting plate 22 away from the heat-conducting cylinder 211, and a water inlet 24 is fixedly connected to the upper end of the water tank 23. Cooling water can be injected into the water tank 23 through the water inlet 24, and the water tank 23 is used to store the cooling water.

[0035] Preferred, such as Figure 4 As shown, a water pump 25 is fixedly connected to the upper end of the water tank 23, and a water pump pipe 26 is fixedly connected to the lower end of the water pump 25. A first water guide pipe 27 is fixedly connected to the upper end of the water pump 25, and the end of the first water guide pipe 27 away from the water pump 25 passes through the water tank 23 and is fixedly connected to the second heat conduction plate 22. After the water pump 25 is running, it can draw cooling water from the water tank 23 through the water pump pipe 26, and then transport the cooling water to the second heat conduction plate 22 through the first water guide pipe 27.

[0036] Preferred, such as Figure 6As shown, a second water pipe 28 is fixedly connected to the end of the second heat-conducting plate 22 away from the first water pipe 27, and a baffle 29 is fixedly connected to the end of the second water pipe 28 away from the second heat-conducting plate 22. Multiple sets of drain holes 210 are opened at the lower end of the baffle 29. After the cooling water flows and absorbs heat in the second heat-conducting plate 22, it enters the baffle 29 through the second water pipe 28 and then sprays out through the drain holes 210.

[0037] Preferred, such as Figure 4 and Figure 5 As shown, a heat-conducting cylinder 211 is fixedly connected to the outer side of the second water pipe 28 near the baffle 29, and a third heat-conducting plate 212 is fixedly connected to the lower end of the heat-conducting cylinder 211. The end of the heat-conducting cylinder 211 away from the second water pipe 28 is fixedly connected to the water tank 23. After the cooling water flows in the heat-conducting cylinder 211, it absorbs heat from the cooling water through the heat-conducting cylinder 211 and the third heat-conducting plate 212.

[0038] Preferred, such as Figure 4 and Figure 5 As shown, multiple sets of third heat-conducting plates 212 are fixedly connected to the lower side of the heat-conducting cylinder 211, and the thickness of the third heat-conducting plate 212 is set to 2CM.

[0039] Preferred, such as Figure 2 and Figure 3 As shown, a protective cover 213 is fitted on the outside of the water tank 23 and the second heat conduction plate 22, and the two ends of the protective cover 213 are threaded with the first fixing bolt 214. The end of the first fixing bolt 214 away from the protective cover 213 is threaded in the machine casing 1. The protective cover 213 can be removed by the first fixing bolt 214.

[0040] Preferred, such as Figure 4 As shown, the lower end of the water tank 23 is fixedly connected to the protective cover 213, and the end of the water inlet 24 away from the water tank 23 is set through the protective cover 213.

[0041] Preferred, such as Figure 1 As shown, filter screen plates 215 are inserted inside both ends of the protective cover 213, and second fixing bolts 216 are threaded inside both ends of the filter screen plates 215. The end of the second fixing bolt 216 near the protective cover 213 is threaded inside the protective cover 213, and the filter screen plates 215 can be removed, replaced and cleaned through the second fixing bolts 216.

[0042] Preferred, such as Figure 4 As shown, a bracket 217 is fixedly connected inside the end of the protective cover 213 away from the water tank 23, and a fan 218 is fixedly connected to the inner side of the upper end of the fan 218. The operation of the fan 218 can make the airflow flow to form airflow, thereby using the airflow to dissipate heat from the third heat conduction plate 212.

[0043] The operation of the enclosed cabinet heat dissipation structure provided by this utility model is as follows: When the cabinet needs heat dissipation during use, the heat generated by the electronic components 12 is absorbed by the first heat-conducting plate 21. The heat absorbed by the first heat-conducting plate 21 is conducted to the second heat-conducting plate 22. Then, the water pump 25 and fan 218 are controlled by the control panel 11. After the water pump 25 starts, it draws cooling water from the water tank 23 through the water pipe 26. The drawn cooling water is transported to the second heat-conducting plate 22 through the first water pipe 27. The cooling water absorbs the heat absorbed by the second heat-conducting plate 22 by flowing in the second heat-conducting plate 22. The cooling water that has absorbed the heat is transported to the baffle 29 through the second water pipe 28. The cooling water that reaches the baffle 29 falls into the heat-conducting cylinder 211 through the drain hole 210. Then, the cooling water that has absorbed the heat flows in the heat-conducting cylinder 211. The heat-conducting cylinder 211 and the third heat-conducting plate 212 absorb heat from the cooling water. The cooled water with absorbed heat then enters the water tank 23 for circulation. The fan 218 operates under the support of the bracket 217. The operation of the fan 218 causes the surrounding air to flow, forming an airflow. After the airflow, the external air enters the protective cover 213 from the filter plate 215 at the end near the water tank 23. Subsequently, the airflow exits from the filter plate 215 at the end of the protective cover 213 near the bracket 217. The airflow carries away the heat from the third heat-conducting plate 212. The filter plate 215 can be removed and cleaned by unscrewing the second fixing bolt 216, or the protective cover 213 can be removed by unscrewing the first fixing bolt 214 to repair the internal parts. When it is necessary to add cooling water, it is injected into the water tank 23 through the water inlet 24.
