Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of heat dissipation of electronic devices, and in particular to a heat dissipation cabinet. Background Art

[0002] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present disclosure, and shall not necessarily be regarded as an admission or any form of suggestion that the information constitutes the relevant technology that has been known to ordinary technicians in the field.

[0003] In the related art, independent fans, water cooling and other methods are usually used to dissipate heat from electronic devices. Compared with the heat dissipation of electronic devices in an open space, the above methods are more practical, but they are not ideal for the heat dissipation of electronic devices in a closed space. Since the closed space has a low ability to interact with the outside air, the temperature is basically kept at a constant value. Therefore, even if a fan is used, it only circulates the air in the closed space, and the temperature cannot be reduced.

[0004] Although water cooling has improved the cooling effect, when the ambient temperature is low, the electronic devices cannot dissipate the heat, resulting in the equipment still needing to cool the devices, which greatly increases the energy consumption of the equipment and increases costs. Utility Model Content

[0005] To this end, an embodiment of the present disclosure provides a heat dissipation cabinet to achieve the purpose of efficiently dissipating heat from electronic devices in a closed space and reducing heat dissipation costs.

[0006] In order to achieve the above objectives, the embodiments of the present disclosure provide the following technical solutions:

[0007] In a first aspect of the embodiments of the present disclosure, a heat dissipation cabinet is provided, forming a cover-type cooling structure, comprising:

[0008] A gas-liquid heat exchanger is arranged at the air inlet end of the cover-type cooling structure, and the gas-liquid heat exchanger is connected to the liquid cooling unit through a bidirectional liquid cooling pipeline;

[0009] A fan is arranged at the exhaust end of the hood-type cooling structure;

[0010] A first temperature sensor is arranged on the outside of the gas-liquid heat exchanger;

[0011] The gas-liquid heat exchanger and the fan are started separately and / or simultaneously according to the difference between the detected temperature of the first temperature sensor and the internal working temperature of the cover-type cooling structure, and the air inlet end and the exhaust end of the cover-type cooling structure are arranged oppositely.

[0012] In a disclosed example, a second temperature sensor is provided on the inner side of the gas-liquid heat exchanger, and the detection temperature of the second temperature sensor is lower than the internal working temperature of the cover-type cooling structure.

[0013] In a disclosed example, rainproof shutters are provided on the outside of the gas-liquid heat exchanger and the fan, and the first temperature sensor is arranged on the rainproof shutter on one side of the gas-liquid heat exchanger.

[0014] In a disclosed example, filters are provided between the gas-liquid heat exchanger and the rainproof louver, and between the fan and the rainproof louver.

[0015] In a disclosed example, a wind shield is provided on the inner side of the exhaust end of the cover-type cooling structure, and the fan is arranged inside the wind shield.

[0016] According to the embodiments of the present disclosure, the heat dissipation cabinet has the following advantages: it includes an air-liquid heat exchanger, which is arranged at the air inlet end of the cover-type cooling structure, and the air-liquid heat exchanger is connected to the liquid cooling unit through a two-way liquid cooling pipeline; a fan is arranged at the exhaust end of the cover-type cooling structure; a first temperature sensor is arranged on the outside of the air-liquid heat exchanger; the air-liquid heat exchanger and the fan are started separately and / or simultaneously according to the difference between the detection temperature of the first temperature sensor and the internal working temperature of the cover-type cooling structure, and the air inlet end and the exhaust end of the cover-type cooling structure are arranged opposite to each other. It adopts a two-way straight-through cooling structure. According to the temperature difference between the ambient temperature and the heat-generating electronic components, the operation of the two-way straight-tube cooling structure is adjusted. When the ambient temperature is lower than the derating temperature of the heat-generating component, fan cooling is performed. When the ambient temperature is higher than the derating temperature of the heat-generating component, the ambient temperature will be lowered to ensure that the air inlet temperature of the heat-generating component is always lower than the derating temperature. For certain application environments, such as when the ambient temperature exceeds the derating temperature of the heat-generating component for only a few hours a day, this structure not only ensures the normal heat dissipation and high-efficiency operation of the electronic components, but also greatly saves the energy consumption of the entire machine. The structure is simple and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a description of the implementation methods of the present disclosure by specific specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

[0023] like Figure 1 As shown, it shows a disassembly diagram of the heat dissipation cabinet in the embodiment of the present disclosure. The heat dissipation cabinet is a cover-type cooling structure, and the specific structure includes an air-liquid heat exchanger 1 connected to a liquid cooling unit 3 through a bidirectional liquid cooling pipeline 2 at the air inlet end of the cover-type cooling structure; a first temperature sensor 5 is arranged on the outside of the air-liquid heat exchanger 1, and the air-liquid heat exchanger 1 and the fan 4 are started separately and / or simultaneously according to the difference between the detection temperature of the first temperature sensor 5 and the internal working temperature of the cover-type cooling structure, and the air inlet end and the exhaust end of the cover-type cooling structure are arranged oppositely.

[0024] It adopts a two-way straight-through cooling structure, and adjusts the operation of the two-way straight-tube cooling structure according to the temperature difference between the ambient temperature and the heat-generating electronic device 11. When the ambient temperature is lower than the derating temperature of the heat-generating device, the fan 4 is cooled. When the ambient temperature is higher than the derating temperature of the heat-generating device, the ambient temperature will be lowered to ensure that the air inlet temperature of the heat-generating device is always lower than the derating temperature. For certain application environments, such as: the ambient temperature will exceed the derating temperature of the heat-generating device only for a few hours a day, this structure not only ensures the normal heat dissipation and high-efficiency operation of the electronic devices, but also greatly saves the energy consumption of the whole machine. The structure is simple and stable.

[0025] like Figure 2As shown, in this embodiment, the heat dissipation cabinet is arranged on the rack 10, and a heat-generating electronic device 11 is arranged in the middle position of the rack 10. The entire heat dissipation cabinet forms a cover-type cooling structure to isolate the heat-generating electronic device 11 from the outside, forming a compartment structure under a closed condition. The rack 10 is provided with two layers, the inner layer is a separated inner chamber where the heat-generating electronic device 11 is located, and the upper layer is provided with a liquid cooling unit 3;

[0026] The hood-type cooling structure is a through-type structure, that is, the air inlet end and the exhaust end are arranged opposite to each other, and the air inlet end is provided with a gas-liquid heat exchanger 1 connected to the liquid cooling unit 3 through a bidirectional liquid cooling pipeline 2, and a filter 8 and a rainproof shutter 7 are arranged outside the gas-liquid heat exchanger 1, and a first temperature sensor 5 is arranged on the rainproof shutter 7;

[0027] The exhaust end is provided with a fan 4 installed in a wind shield 9. The wind shield 9 can achieve a drainage effect when the fan 4 is turned on, thereby improving the purpose of the fan 4 for efficiently cooling the air in the inner room where the heat-generating electronic device 11 is located by efficient convection cooling, while preventing the fan 4 from being disturbed by external factors. The outside of the fan 4 is also provided with a filter 8 and a rainproof shutter 7;

[0028] Since the first temperature sensor 5 is arranged in the outer room, it detects the ambient temperature of the outer room. When the first temperature sensor 5 detects that the ambient temperature is lower than the derating temperature of the heat-generating electronic device 11, the heat is dissipated by the fan 4 to the heat-generating electronic device 11; when the first temperature sensor 5 detects that the ambient temperature is higher than the derating temperature of the heat-generating electronic device 11, the liquid cooling unit works to cool the liquid with lower cooling temperature through the liquid cooling pipeline and transports it to the gas-liquid heat exchanger 1, so that the high-temperature airflow flowing into the inner room is cooled first, thereby avoiding indirectly heating up the heat-generating electronic device 11.

[0029] In this embodiment, a second temperature sensor 6 is provided on the inner side of the gas-liquid heat exchanger 1, that is, the second sensor is arranged in the inner room, and the detection temperature of the second temperature sensor 6 is lower than the internal working temperature of the cover-type cooling structure, and its purpose is to ensure that the temperature of the heat-generating electronic components is constant within the optimal working temperature range. When the air from the outer room enters the cabinet through the gas-liquid heat exchanger 1, the air is cooled by the gas-liquid heat exchanger 1, thereby ensuring the normal and efficient operation of the heat-generating electronic components 11, and then the second temperature sensor 6 is used for feedback to always keep the air inlet temperature just lower than the derated temperature of the heat-generating electronic components 11, so that the liquid cooling unit can operate at the lowest possible power to save energy; this method not only ensures the normal and efficient operation of the heat-generating components, but also greatly reduces the energy consumption of heat dissipation and improves the overall working efficiency of the equipment.

[0030] The rainproof shutters 7 prevent rainwater from entering the cabinet, and the filter 8 prevents dust from entering to ensure the efficient operation of the gas-liquid heat exchanger 1. The first temperature sensor 5 measures the ambient temperature, and the second temperature sensor 6 detects the temperature drop after passing through the gas-liquid heat exchanger 1 and feeds back the temperature to the liquid cooling unit. The liquid cooling unit adjusts the start and stop and the operating power according to the temperature. The wind shield 9 ensures that the hot air can be discharged efficiently to prevent the hot air from flowing back. The fan 4 blows the hot air out of the warehouse to achieve heat dissipation. The filter 8 prevents dust from entering, and the rainproof shutters 7 prevent rainwater from entering the cabinet.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0032] Although the present disclosure has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made to the present disclosure. Therefore, these modifications or improvements made without departing from the spirit of the present disclosure are within the scope of protection claimed by the present disclosure.
