Description

Technical Field

[0001] This utility model relates to the field of thermal conductivity technology for aluminum alloy thin plates, and in particular to a high thermal conductivity aluminum alloy thin plate structure. Background Technology

[0002] Due to its excellent thermal conductivity, aluminum alloy sheet has a variety of applications in daily life. For example, it is used for heat dissipation in electronic devices such as mobile phones, laptops, tablets, and televisions. The heat sinks or outer shells of these devices often use aluminum alloy sheet structures. In kitchen utensils, stainless steel is commonly used for the bottom of non-stick pans, the inner pot of rice cookers, oven baking trays, and the heat-conducting layer of air fryers. In addition, thin aluminum alloy sheets are also used in the heat dissipation systems of home appliances such as the heat sinks of outdoor air conditioning units, the heat sinks of refrigerator compressors, and the heat dissipation components of hair dryers / vacuum cleaner motors.

[0003] In existing technologies, aluminum alloy sheets are typically used to conduct heat from electronic components by directly contacting them in sheet form. For example, an aluminum alloy sheet is placed on the top of an LED bead. Alternatively, fins are used to improve heat conduction and dissipation. For instance, in the air-cooling method for computer CPU chips, an aluminum alloy sheet is placed in direct contact with the chip, and a large number of evenly distributed fins are arranged around the aluminum alloy sheet to improve heat dissipation efficiency.

[0004] The aluminum alloy sheet with the above structure has good thermal conductivity and heat dissipation within a certain range. However, when the heat generated by the heating element is large and the heat needs to be dissipated quickly, the above structure may not meet the actual needs.

[0005] Therefore, it is necessary to provide a high thermal conductivity aluminum alloy sheet structure to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a high thermal conductivity aluminum alloy thin plate structure that can improve the heat dissipation effect of the aluminum alloy thin plate by combining air cooling and water cooling.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] Preferably, the upper end of the accommodating compartment is detachably provided with a cover plate, and the upper end of the cover plate is provided with a plurality of prefabricated grooves, which are recessed towards the lower end of the cover plate.

[0010] Preferably, the grating plate is made of copper and extends through the partition plate, with the upper ends of both plates located on the same horizontal plane, and the air holes are arranged alternately with the grating plate.

[0011] Preferably, the direction of the water holes is parallel to the long axis of the grating plate.

[0012] Preferably, multiple water holes are provided, and the multiple water holes are distributed at equal intervals.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] First embodiment:

[0023] like Figure 1-3As shown, the high thermal conductivity aluminum alloy thin plate structure provided by this utility model includes: a accommodating compartment 101, which is made of aluminum alloy material and has a chamber for accommodating electronic components, batteries, integrated circuits (determined according to actual use), etc., and its shape is as follows. Figure 2 As shown, the lower end of the accommodating chamber 101 is fixedly connected to the water-cooling chamber 102, which is also made of aluminum alloy. The two can be fixed by laser welding. Water holes 105 are provided on one side and the opposite side of the water-cooling chamber 102. Inlet and outlet water ports are installed at the water holes 105. A partition plate 106 is horizontally arranged on the inner wall of the accommodating chamber 101, dividing the internal space of the accommodating chamber 101 into upper and lower parts. Several parallel grid plates 104 are provided at the lower end of the partition plate 106. The grid plates 104 are thin aluminum alloy plates, and several air holes 103 are provided perpendicular to the transverse direction of the partition plate 106, penetrating the left and right sides of the partition plate 106. For example, a power battery is placed inside the accommodating chamber 101. The power battery generates a large amount of heat during operation. Power batteries are commonly used in new energy vehicles. In devices with high power consumption, when a new energy vehicle is moving, the device moves along with the vehicle. Airflow passes through the vent 103, and the heat generated by the power battery is transferred to the partition plate 106. Since the vent 103 runs through the partition plate 106, the airflow carries away the heat near the vent 103, thereby improving the heat conduction efficiency of the containment chamber 101. On the other hand, the heat in the partition plate 106 continues to be conducted downwards into the grille plate 104. The grille plate 104 is immersed in the water-cooled chamber 102. The heat on the grille plate 104 is transferred to the coolant in the water-cooled chamber 102. The coolant is circulated in the water-cooled chamber 102 by a pump through the water hole 105. The cooling and circulation of the coolant are accomplished using existing technology, which will not be elaborated here. This achieves the effect of transferring the heat on the grille plate 104 to the coolant.

[0024] By setting up air holes 103 and water holes 105 and other related components, the heat generated by electronic components and other heat-generating elements in the accommodating chamber 101 is conducted, thereby improving the heat dissipation effect of the structure compared with the prior art.

[0025] Second embodiment:

[0026] like Figure 1-2As shown, the upper end of the accommodating compartment 101 is provided with a cover plate 107. The accommodating compartment 101 and the cover plate 107 are provided with corresponding connecting ends on the frame 108 around them. The connecting ends are provided with through holes, and bolts are installed in the through holes to connect the cover plate 107 to the accommodating compartment 101. The upper end of the cover plate 107 is provided with several prefabricated grooves 109. The prefabricated grooves 109 are recessed towards the lower end of the cover plate 107. The prefabricated grooves 109 are located in the gaps between electronic components of different shapes and structures, depending on the location of the electronic components. The distance between the electronic components and the outer wall of the prefabricated grooves 109 is closer than that of the cover plate 107, so that heat is more easily conducted. In addition, the prefabricated grooves 109 increase the surface area of ​​the upper and lower ends of the cover plate 107.

[0027] By setting up prefabricated grooves 109, the heat conduction efficiency of heat-generating elements such as electronic components is improved by increasing the contact area.

[0028] Third embodiment:

[0029] like Figure 3 As shown, the grating plate 104 is made of copper, and the thermal conductivity of copper is about twice that of stainless steel. The partition plate 106 has mounting holes on its surface that are compatible with the grating plate 104. The grating plate 104 is installed through the partition plate 106, and the upper ends of the two are located on the same horizontal plane. The vent 103 is arranged between two adjacent grating plates 104, and the vent 103 and the grating plate 104 are arranged at intervals.

[0030] By replacing the grid plate 104 with copper, which has a higher thermal conductivity, the efficiency of heat transfer from the containment chamber 101 to the grid plate 104 and the water-cooled chamber 102 can be improved. In addition, when the airflow flows through the air hole 103, it can carry some of the heat from the grid plate 104 located nearby into the air.

[0031] Fourth embodiment:

[0032] like Figure 2 As shown, the direction of the water hole 105 is parallel to the long axis of the grid plate 104. After the cold water flows into the water-cooled chamber 102 through the water hole 105, the water flow direction is consistent with the direction of the grid plate 104. The cold water then enters the gaps between the grid plates 104. In order to improve the cooling effect of the cold water on the grid plate 104, two water holes 105 are provided. The two water holes 105 are equidistantly distributed. The water enters the water-cooled chamber 102 from two positions. The cold water flow can reach the edge of the water-cooled chamber 102 to a greater extent, thereby directly cooling the entire grid plate 104 in the water-cooled chamber 102.

[0033] Working principle: Since the air hole 103 runs through the partition plate 106, the airflow carries away the heat near the air hole 103, thereby improving the heat conduction efficiency of the container 101. On the other hand, the heat in the partition plate 106 continues to be conducted downward into the grid plate 104. Through the synergistic work of the two, the heat conduction and heat dissipation effect of the aluminum alloy sheet is improved.

[0034] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
