Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a heat dissipation device and a heat dissipation cabinet. Background Art

[0002] When the electrical control cabinet is used on an offshore work platform, the environment of the offshore work platform is harsh, and the humidity and salinity are much higher than on land. In order to reduce the erosion of the external environment on the inside of the electrical control cabinet, the electrical control cabinet is generally sealed. However, since the circuit components inside the electrical control cabinet will generate heat during operation, and the sealed electrical control cabinet has poor heat dissipation effect, it is necessary to install a heat dissipation device on the electrical control cabinet.

[0003] In the prior art, heat is dissipated by installing an air conditioner on the electrical control cabinet.

[0004] However, there are some problems with using air conditioners to dissipate heat. First, the air conditioner compressor will produce liquid water when running, which increases the probability of short circuits in the electrical control cabinet; second, the compressor has a large power and consumes a lot of electricity, so the cost is high. Utility Model Content

[0005] The utility model discloses a heat dissipation device and a heat dissipation cabinet. When the heat dissipation device is used to dissipate heat from the heat dissipation cabinet, on the one hand, liquid water will not be generated, thereby reducing the probability of a short circuit in the circuit inside the heat dissipation cabinet. On the other hand, the heat dissipation device does not use a compressor, thereby consuming less electric energy, thereby reducing operating costs.

[0006] In order to achieve the above-mentioned purpose, the utility model discloses a heat dissipation device, which includes: an internal circulation part, an external circulation part and a heat transfer plate. The internal circulation part includes an internal gas cavity, an internal air inlet, an internal air outlet and an internal circulation power device, the internal air inlet and the internal air outlet are both connected to the internal gas cavity, the internal circulation power device is used to generate an internal circulation airflow, and the internal circulation airflow flows through the internal air inlet, the internal gas cavity and the internal air outlet in sequence. The external circulation part includes an external gas cavity, an external air inlet, an external air outlet and an external circulation power device, the external air inlet and the external air outlet are both connected to the external gas cavity, the external circulation power device is used to generate an external circulation airflow, and the external circulation airflow flows through the external air inlet, the external gas cavity and the external air outlet in sequence. The heat transfer plate is located between the internal gas cavity and the external gas cavity to isolate the internal gas cavity and the external gas cavity, and the internal gas cavity can transfer heat to the external gas cavity through the heat transfer plate.

[0007] Optionally, the heat transfer plate includes a hydrophilic aluminum foil plate, and the inner surface and outer surface of the hydrophilic aluminum foil plate are in contact with the inner gas cavity and the outer gas cavity respectively.

[0008] Optionally, the hydrophilic aluminum foil plate is a corrugated plate.

[0009] Optionally, the internal circulation power device and / or the external circulation power device includes a circulation pump.

[0010] Optionally, the circulation pump comprises an electric motor.

[0011] Optionally, the heat dissipation device includes a solar cell, and the solar cell is used to supply power to the electric motor.

[0012] Optionally, the heat dissipation device also includes an automatic adjustment system, which includes a temperature detection element and a control component, and the internal circulation power device, the external circulation power device and the temperature detection element are all electrically connected to the control component.

[0013] In a second aspect, the utility model further discloses a heat dissipation cabinet, which includes any one of the above-mentioned heat dissipation devices.

[0014] Optionally, a protective cover is provided on the top of the heat dissipation cabinet.

[0015] Optionally, the shell of the heat dissipation cabinet is a stainless steel shell.

[0016] Compared with the related art, the beneficial effects of the present application are at least:

[0017] Since the inner air inlet and the inner air outlet are both connected to the inner gas cavity, the inner circulation power device is used to generate an inner circulation airflow, which flows through the inner air inlet, the inner gas cavity and the inner air outlet in sequence, so that the air in the inner space can form an airflow for outputting heat, and the faster the inner gas flows, the faster the heat dissipation speed is, which is beneficial to the heat dissipation of the inner space. Next, since the outer air inlet and the outer air outlet are both connected to the outer gas cavity, the outer circulation power device is used to generate an outer circulation airflow, which flows through the outer air inlet, the outer gas cavity and the outer air outlet in sequence, so that the air in the outer space can form an airflow for absorbing heat, and the faster the outer gas flows, the faster the heat absorption speed is, which is beneficial to the heat absorption of the outer space.

[0018] Then, since the heat transfer plate is located between the inner gas cavity and the outer gas cavity, the inner gas cavity and the outer gas cavity are isolated, and the inner gas cavity can transfer heat to the outer gas cavity through the heat transfer plate. In this way, not only the heat of the inner space can be quickly transferred to the outer space, but also the inner space and the outer space can be completely isolated.

[0019] Finally, since the heat dissipation device does not use air conditioning for heat dissipation, the heat dissipation device does not produce liquid water during operation, thereby reducing the probability of short circuits in the circuit inside the heat dissipation cabinet. In addition, the heat dissipation device does not use a compressor, thereby consuming less electrical energy, thereby reducing operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0040] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0041] Figure 1 is a schematic structural diagram of a heat dissipation device 100 provided in an embodiment of the present application. Figure 2 yes Figure 1 Schematic diagram of the structure of the heat transfer plate 3.

[0042] See also Figure 1and Figure 2 The heat dissipation device 100 includes: an internal circulation part 1, an external circulation part 2 and a heat transfer plate 3. The internal circulation part 1 includes an internal gas cavity 11, an internal air inlet 12, an internal air outlet 13 and an internal circulation power device 14. The internal air inlet 12 and the internal air outlet 13 are both connected to the internal gas cavity 11. The internal circulation power device 14 is used to generate an internal circulation airflow, and the internal circulation airflow flows through the internal air inlet 12, the internal gas cavity 11 and the internal air outlet 13 in sequence. The external circulation part 2 includes an external gas cavity 21, an external air inlet 22, an external air outlet 23 and an external circulation power device 24. The external air inlet 22 and the external air outlet 23 are both connected to the external gas cavity 21. The external circulation power device 24 is used to generate an external circulation airflow, and the external circulation airflow flows through the external air inlet 22, the external gas cavity 21 and the external air outlet 23 in sequence. The heat transfer plate 3 is located between the inner gas cavity 11 and the outer gas cavity 21 to isolate the inner gas cavity 11 from the outer gas cavity 21 . The inner gas cavity 11 can transfer heat to the outer gas cavity 21 through the heat transfer plate 3 .

[0043] In this embodiment, since the inner air inlet 12 and the inner air outlet 13 are both connected to the inner gas cavity 11, the inner circulation power device 14 is used to generate an inner circulation airflow, and the inner circulation airflow flows through the inner air inlet 12, the inner gas cavity 11 and the inner air outlet 13 in sequence, so that the air in the inner space can form an airflow for outputting heat, and the faster the inner gas flows, the faster the heat dissipation speed is, which is beneficial to the heat dissipation of the inner space. Next, since the outer air inlet 22 and the outer air outlet 23 are both connected to the outer gas cavity 21, the outer circulation power device 24 is used to generate an outer circulation airflow, and the outer circulation airflow flows through the outer air inlet 22, the outer gas cavity 21 and the outer air outlet 23 in sequence, so that the air in the outer space can form an airflow for absorbing heat, and the faster the outer gas flows, the faster the heat absorption speed is, which is beneficial to the heat absorption of the outer space.

[0044] Next, since the heat transfer plate 3 is located between the inner gas cavity 11 and the outer gas cavity 21, the inner gas cavity 11 and the outer gas cavity 21 are isolated, and the inner gas cavity 11 can transfer heat to the outer gas cavity 21 through the heat transfer plate 3. In this way, not only is it ensured that the heat in the inner space can be quickly transferred to the outer space, but the inner space and the outer space can also be completely isolated.

[0045] Finally, since the heat dissipation device 100 does not use air conditioning for heat dissipation, the heat dissipation device 100 does not generate liquid water during operation, thereby reducing the probability of short circuits in the circuits inside the heat dissipation cabinet 200. In addition, the heat dissipation device 100 does not use a compressor, thereby consuming less electrical energy, thereby reducing operating costs.

[0046] It should be noted that the heat dissipation device 100 is arranged on the inner side of the enclosed space where heat dissipation is required and on the outer side corresponding to the inner side. The enclosed space may be an enclosed building or an enclosed cabinet. When the enclosed space is an enclosed cabinet, it may be an electrical control cabinet or an equipment protection cabinet, which is not limited in the present embodiment.

[0047] See also Figure 1 When the heat dissipation device 100 is used for heat dissipation, Figure 1 The airflow represented by the left arrow is the internal circulating airflow, and the airflow represented by the right arrow is the external circulating airflow. The internal circulating airflow and the external circulating airflow exchange heat through the heat transfer plate 3 in the internal gas cavity 11 and the external gas cavity 21 respectively, and then transfer the heat of the internal space to the external space to achieve heat dissipation.

[0048] In some embodiments, see Figure 1 and Figure 2 The heat transfer plate 3 includes a hydrophilic aluminum foil plate 31, and the inner surface and outer surface of the hydrophilic aluminum foil plate 31 are in contact with the inner gas cavity 11 and the outer gas cavity 21 respectively. Since the hydrophilic aluminum foil has a high thermal conductivity, the efficiency of heat transfer from the inner gas cavity 11 to the outer gas cavity 21 can be improved, so the heat dissipation efficiency of the heat dissipation device 100 can be improved. In addition, the hydrophilic aluminum foil has good corrosion resistance, which prolongs the service life of the heat dissipation device 100, thereby reducing the use cost of the heat dissipation device 100.

[0049] In order to increase the heat exchange area of ​​the hydrophilic aluminum foil plate 31, in some embodiments, see Figure 1 , Figure 2 and Figure 3 The hydrophilic aluminum foil plate 31 is a corrugated plate. In this way, the heat exchange area of ​​the hydrophilic aluminum foil plate 31 is increased, thereby improving the efficiency of heat transfer from the internal gas cavity 11 to the external gas cavity 21, thereby improving the heat dissipation efficiency of the heat dissipation device 100.

[0050] In some embodiments, see Figure 1 and Figure 2 The internal circulation power device 14 includes a circulation pump 141. The circulation pump 141 is a common power device for generating airflow, which can provide a stable pressure for the internal gas circulation, thereby generating a stable internal circulation airflow, thereby improving the heat dissipation efficiency of the heat dissipation device 100.

[0051] And / or, the external circulation power device 24 includes a circulation pump 141. The technical features and functions of the circulation pump 141 are the same as those of the internal circulation power device 14, so they are not described in detail here.

[0052] In some embodiments, see Figure 1The circulating pump 141 includes an electric motor 1411. The electric motor 1411 is a common power device, and its production, installation and maintenance technology are mature, so it can reduce the use cost of the heat dissipation device 100. In addition, using the electric motor 1411 as the power device of the circulating pump 141 will not pollute the environment, so it has the effect of green environmental protection.

[0053] In some embodiments, see Figure 1 The heat dissipation device 100 includes a solar cell 4, which is used to power the motor 1411. The solar cell 4 uses solar energy to generate and store electricity, and the heat dissipation device 100 does not need an external power supply, so that no external electric energy is consumed, thereby reducing the use cost of the heat dissipation device 100.

[0054] In order to realize the automatic adjustment function of the heat dissipation device 100, in some embodiments, see Figure 1 and Figure 4 The heat dissipation device 100 also includes an automatic adjustment system 5, which includes a temperature detection element 51 and a control element 52. The internal circulation power device 14, the external circulation power device 24 and the temperature detection element 51 are all electrically connected to the control element 52. When the temperature of the internal space is higher than the preset temperature, the temperature detection element 51 can detect the high temperature, generate high temperature information and send the high temperature information to the control element 52. After receiving the high temperature information, the control element 52 can control and start the internal circulation power device 14 and the external circulation power device 24, and the higher the temperature, the greater the power of the internal circulation power device 14 and the external circulation power device 24. When the temperature of the internal space is lower than the preset temperature, the temperature detection element 51 can detect the low temperature, generate low temperature information and send the low temperature information to the control element 52. After receiving the low temperature information, the control element 52 can control and shut down the internal circulation power device 14 and the external circulation power device 24.

[0055] The above adjustment process can be repeated according to the temperature change of the internal space, so that the heat dissipation device 100 realizes the function of automatically adjusting the temperature. In addition, when the temperature of the internal space is lower than the preset temperature, the internal circulation power device 14 and the external circulation power device 24 are in a closed state, thereby reducing energy consumption and thus reducing the use cost.

[0056] The present application also provides a heat dissipation cabinet 200, see Figure 1 and Figure 5, the heat dissipation cabinet 200 includes any one of the above-mentioned heat dissipation devices 100. That is, the heat dissipation device 100 is installed on the heat dissipation cabinet 200, wherein the internal circulation power device 14 is located inside the heat dissipation cabinet 200, and the external circulation power device 24 is located outside the heat dissipation cabinet 200. In this way, since the heat dissipation device 100 does not use air conditioning for heat dissipation, the heat dissipation device 100 does not generate liquid water during operation, thereby reducing the probability of short circuit in the circuit inside the heat dissipation cabinet 200. In addition, the heat dissipation device 100 does not use a compressor, thereby consuming less electrical energy, thereby reducing operating costs.

[0057] It should be noted that the heat dissipation cabinet 200 may be an electrical equipment cabinet, a test equipment cabinet, or other cabinets with the same heat dissipation requirements, which is not limited in the present embodiment. When the heat dissipation cabinet 200 is an electrical equipment cabinet, it may be an electrical control cabinet or an equipment protection cabinet, which is not limited in the present embodiment.

[0058] In some embodiments, see Figure 5 A protective cover 300 is provided on the top of the heat dissipation cabinet 200. The protective cover 300 has a waterproof performance, so that the heat dissipation cabinet 200 can also be waterproof, and then the heat dissipation cabinet 200 can be set outdoors, thus increasing the applicable scope of the heat dissipation cabinet 200.

[0059] To enhance the anti-corrosion capability of the heat dissipation cabinet 200, in some embodiments, see Figure 5 The outer shell of the heat dissipation cabinet 200 is a stainless steel outer shell. Since stainless steel has good anti-corrosion performance, the anti-corrosion ability of the heat dissipation cabinet 200 is enhanced. In this way, even if the heat dissipation cabinet 200 is set on an offshore working platform, the erosion effect of the external environment on the inside of the heat dissipation cabinet 200 can be reduced.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
