Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation methods of electric cabinets, and in particular to an electric cabinet with a heat dissipation system having high-efficiency heat dissipation performance. Background Art

[0002] Existing electrical cabinets, such as the wafer stage remote cabinet (WSRC), are mainly equipped with multiple layers of electrical boards in a cabinet. The electronic components installed on the electrical boards are used to perform specific calculations, controls, and other operations. When each electronic component is operated for a long time, it will generate heat. If the heat in the cabinet cannot be properly discharged, it will affect the normal operation of each electrical board and electronic components. Figure 3 As shown, it is a heat dissipation system of an existing electric cabinet, which is mainly provided with a horizontal heat dissipation fan 50 on the cabinet body of the existing electric cabinet, and an air inlet 52 is provided on the bottom surface of the electric cabinet, and an exhaust port 54 is provided on the top surface of the electric cabinet. When the heat dissipation fan 50 is running, the cold air around the electric cabinet will enter the electric cabinet through the air inlet 52, flow upward and perform heat exchange with the electric panels arranged in the cabinet to produce the effect of heat dissipation and cooling, and then the hot air will be discharged from the exhaust port 54, so that a certain temperature can be maintained in the electric cabinet to avoid damage to the electric panels and electronic components in the electric cabinet due to the heat generated by long-term operation.

[0003] However, the heat dissipation system of the existing electric cabinet has an air inlet 52 located at the bottom of the electric cabinet and an air outlet 54 located at the top of the electric cabinet. Therefore, the temperature of the cold air entering from the bottom of the electric cabinet will continue to rise after heat exchange with the electric panels located at the lower level of the electric cabinet. As a result, the predetermined heat dissipation effect cannot be achieved for the electric panels located at the upper level of the electric cabinet. Therefore, the heat dissipation system of the existing electric cabinet will cause heat to be concentrated on the upper electric panels, which will damage the upper electric panels, causing premature aging of the electric panels and overheating and damage of electronic components. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an electric cabinet with a heat dissipation system, which is used to solve the problem that the heat dissipation system of the electric cabinet in the prior art causes heat energy to be concentrated on the upper layer of the electric cabinet, causing damage to the electric board.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides an electric cabinet with a heat dissipation system, the electric cabinet including a cabinet body that takes in air from the bottom and exhausts air from the top, a plurality of layers of electric boards arranged up and down are arranged in the cabinet body, and at least one horizontal fan is arranged horizontally at a position corresponding to a middle layer of electric boards in the cabinet body to guide air to flow from a lower air inlet to an upper exhaust port, and a plurality of groups of cold air devices are arranged on the side of the cabinet body respectively corresponding to the positions of each layer of electric boards, wherein the position of at least one group of cold air devices is higher than the position of the horizontal fan.

[0031] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. For example, when describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional view showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] For ease of description, spatially relative terms such as "under", "below", "below", "below", "above", "on", etc. may be used herein to describe the relationship of one component or feature to other components or features shown in the drawings. It will be understood that these spatially relative terms are intended to encompass other orientations of the device in use or operation in addition to the orientation depicted in the drawings. In addition, when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or one or more intervening layers may also be present.

[0033] In the context of this application, the structure described as a first feature "above" a second feature may include an embodiment in which the first and second features are formed in direct contact, and may also include an embodiment in which another feature is formed between the first and second features, so that the first and second features may not be in direct contact. In this specification, the terms "first" and "second" are used for convenience of description and are not limiting.

[0034] It should be noted that the diagrams provided in this embodiment are only schematic illustrations of the basic concept of the present invention, and the diagrams only show the components related to the present invention rather than the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation may be changed at will, and the layout of the components may also be more complicated. In order to make the diagrams as concise as possible, not all structures are marked in the drawings.

[0035] like Figure 1 As shown, the present invention provides an electric cabinet with a heat dissipation system, the electric cabinet includes a cabinet body 10, and a plurality of layers of electric boards arranged up and down are arranged in the cabinet body 10, so as to utilize the electronic components arranged on the electric boards to perform various operations. The cabinet body 10 is generally in the shape of a rectangular parallelepiped and includes a top surface, a bottom surface, a front side surface, a rear side surface and two side surfaces. The cabinet body is in a state of air intake from the bottom and exhaust from the top, wherein at least one air inlet 12 can be arranged on the bottom surface of the cabinet body 10, and at least one exhaust port 14 can be arranged on the top surface of the cabinet body. At least one horizontal fan 16 is arranged at a position corresponding to a middle layer of electric boards in the cabinet body 10 to guide the air to flow from the lower air inlet to the upper exhaust port. In addition, a plurality of cold air devices corresponding to the positions of each layer of electric boards are arranged on both side surfaces of the cabinet body 10. The cold air device 20 is used to generate cold air and send it into the corresponding electric boards in the cabinet body 10. The cold air device 20 can be a refrigeration host of a fan or an air conditioner. As shown in FIG. Figure 1 As shown, three groups of cooling devices 20 can be set on each side of the counter 10, wherein the position of each cooling device 20 can be the same height as or slightly higher than the corresponding layer of electrical panels, and the position of at least one group of cooling devices 20 is higher than the horizontal fan 16.

[0036] Thus, when the horizontal fan 16 is running, the cold air around the electric cabinet will enter the cabinet 10 through the air inlet 12 on the bottom of the cabinet 10, and flow vertically upward from the bottom of the cabinet 10 under the guidance of the horizontal fan 16, and perform heat exchange with the electric boards arranged in the cabinet 10 in turn to reduce the temperature of the electric boards and electronic components, and then be discharged from the exhaust port 14 on the top of the cabinet 10. In addition, in conjunction with the cold air device 20 arranged on the side of the cabinet 10, the cold air around the electric cabinet can be introduced into the cabinet 10 from the side, which can effectively increase the heat dissipation effect of the electric boards on each layer in the cabinet 10. At the same time, because the position of at least one row of cold air devices is higher than the position of the horizontal fan 16, the higher position of the cold air device 20 can prevent hot air from concentrating on the upper layer in the cabinet 10, thereby preventing the electric boards and electronic components on the upper layer in the cabinet 10 from aging and damage due to excessive temperature, thereby maintaining the good operation of the electric cabinet for a long time.

[0037] In addition, if Figure 2As shown, a cooling and heat exchange system 30 may be further provided in the cabinet body 10 of the electric cabinet, and the cooling and heat exchange system 30 reduces the temperature of the cold air generated by the cold air device 20. In a preferred embodiment of the present invention, the cooling and heat exchange system 30 may pass directly above the plurality of groups of cold air devices 20, so that the temperature of the cold air discharged by the cold air device 20 may be further cooled and reduced by the cooling and heat exchange system 30. In addition, a cooling heat exchange system 30 can also be provided to pass through the top of the horizontal fan 16 at the same time. The cooling heat exchange system 30 mainly includes a pump 32 and a heat pipe 34 connected to the pump 32 and passing through the top of the corresponding cold air device 20 and / or the horizontal fan 16. A coolant is provided in the heat pipe 34 to circulate along the heat pipe 34. The coolant can be a liquid with a cooling effect such as silicone oil. By providing the cooling heat exchange system 30, the temperature of the air flow generated by the horizontal fan 16 and each cold air device 20 can be effectively reduced. Through the convection heat exchange between the horizontal fan 16 and each cold air device 20 and the cabinet 10, the temperature in the cabinet 10 can be effectively reduced to achieve a high-efficiency heat dissipation effect.

[0038] Furthermore, the present invention can also be provided with a heat dissipation pipe 34 corresponding to each group of cold air devices 20 on the cabinet 10. For example, when three groups of cold air devices 20 are provided on both sides of the cabinet 10, three groups of heat dissipation pipes 34 are provided. Each heat dissipation pipe 34 passes through the corresponding cold air device 20 or the top of the horizontal fan 16 and is connected to a pump 32. In this way, the temperature of the air flow generated by all the cold air devices 20 and the horizontal fan can be reduced, thereby effectively reducing the temperature of the cabinet 10.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
