Description

Technical Field

[0001] The invention relates to the technical field of temperature equalizing plate production, and in particular to an auxiliary liquid injection device for an ultra-thin temperature equalizing plate. Background Art

[0002] With the rapid progress of microelectronics technology, mobile terminal products such as smart phones and tablets are developing rapidly towards high performance, high integration and miniaturization. This trend has caused these devices to generate extremely high heat flux density in an extremely limited space, posing a severe challenge to their heat dissipation performance. As a high-efficiency device, the heat spreader is widely used in mobile terminal products with its high thermal conductivity and low thermal resistance, as well as its thinner and superior heat dissipation performance. In order to meet the needs of market development, the thickness of the heat spreader has been reduced to an ultra-thin 0.3mm or less, and this change has prompted adjustments to the manufacturing process.

[0003] The reasonable amount of liquid absorbed by the liquid wick inside the temperature equalizer is the key to ensuring its performance. With the change in thickness, related processes such as the injection process also face more stringent requirements. Due to the reduction in thickness, traditional mechanical automated injection and auxiliary injection methods are no longer applicable, and it is necessary to switch to conventional manual syringe injection. However, this injection method has certain problems: the thinner injection tube will adsorb part of the liquid in the tube due to capillary force. If the vacuum treatment is performed directly, the liquid adsorbed in the injection tube will be drawn away, which will affect the amount of liquid absorbed by the liquid wick and ultimately affect the performance of the temperature equalizer. Therefore, the conventional practice is to assist the injection by artificial shaking after the injection, but this method is inefficient and has a low yield rate. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 9 The present invention provides an auxiliary liquid injection device for an ultra-thin temperature-averaging plate 8, comprising a centrifuge, wherein the centrifuge is provided with a base 1 for placing the temperature-averaging plate 8 to be centrifugally treated inside, and a rotatable upper cover 2 is provided on the base 1, that is, one end of the upper cover 2 is rotatably mounted on the base 1 through a rotating shaft 21, and is used for covering during operation. The front end of the base 1 is also provided with an interactive display screen 3 for performing corresponding control operations and observing relevant operation information. Figure 2 and Figure 3 As shown, a centrifugal chamber 4 is provided inside the base 1, a centrifugal support is provided in the centrifugal chamber 4, a rotating drum 6 is installed on the centrifugal support, a collector 7 is placed in the rotating drum 6, and the collector 7 is used to place a temperature equalizing plate 8. An electric turntable 9 is provided at the inner bottom of the base 1, and the centrifugal support is rotatably installed on the electric turntable 9. When in use, the electric turntable 9 rotates and drives the centrifugal support to rotate, so that the collector 7 placed in the rotating drum 6 is subjected to the centrifugal effect, which causes the liquid core in the temperature equalizing plate 8 to produce a centrifugal effect, thereby achieving the purpose of fully aspirating liquid, avoiding the traditional manual form of shaking and injecting liquid, resulting in a low yield rate.

[0032] The operation process is to place the water-filled temperature-averaging plate 8 on the collector 7 in turn, magnetically attract the lifting auxiliary clamp 19 and the connecting seat 20, and then place the collector 7 into the rotating drum 6, then remove the lifting auxiliary clamp 19, and place the collector 7 equipped with the temperature-averaging plate 8 into each rotating drum 6 in turn according to this method, and cover the upper cover 2, start the centrifuge with the centrifugal time and speed set in advance, and complete the centrifugation process.

[0033] Specifically, Figure 4 As shown, a driving device 10 is provided below the electric turntable 9, and the electric turntable 9 is rotatably mounted on the driving device 10. The driving device 10 is a motor, which drives the electric turntable 9 to rotate, thereby driving the entire centrifugal support to rotate, thereby achieving a centrifugal effect. The centrifugal support includes a central support rod 11 installed on the electric turntable 9, which is used to provide overall stability of the mechanism. Furthermore, reinforcing ribs 12 are provided at both ends of the bottom of the central support rod 11 near the electric turntable 9 to improve stability during rotation. The star-shaped support 5 is provided on the top of the central support rod 11, and the rotating drum 6 is installed on the star-shaped support 5. Therefore, the provision of the reinforcing ribs 12 can ensure that the entire centrifugal support is not shaken during rotation.

[0034] like Figure 5 and Figure 7 As shown, the star-shaped bracket 5 is provided with a plurality of U-shaped mounting notches 13, and a rotating drum 6 is installed in each U-shaped mounting notch 13. The rotating drum 6 is detachably installed in the U-shaped mounting notch 13, so as to facilitate disassembly, replacement, or maintenance after work. That is, an extension rod 14 is provided at both ends of the U-shaped mounting notch 13, and a screw 15 is provided on the extension rod 14. The side walls at both ends of the rotating drum 6 are respectively threadedly connected with the two screws 15 on the two extension rods 14. By fixing the rotating drum 6 with the screws 15, the stability of the rotating drum 6 can be ensured when the centrifugal bracket rotates at a high speed.

[0035] Furthermore, if the number of the multiple U-shaped installation slots 13 is set to an odd number or an even number, the number of the multiple drums 6 is set to an odd number or an even number that matches the U-shaped installation slots 13; if the shape of the multiple U-shaped installation slots 13 is set to a circle or a square, the shape of the multiple drums 6 is set to a circle or a square that matches the U-shaped installation slots 13, thereby achieving a one-to-one correspondence. Similarly, since the multiple drums 6 are all provided with collectors 7, if the number of the multiple collectors 7 is set to an odd number or an even number that matches the drums 6, the shape of the multiple collectors 7 is also set to a circle or a square that matches the drums 6, thereby maintaining the overall aesthetics and integrity.

[0036] like Figure 8 and Fig. 9As shown, since the collector 7 is provided with a plate slot 16, multiple temperature averaging plates 8 can be placed in the collector 7 at one time, thereby improving efficiency. The plate slot 16 is opened at the top of the collector 7, and the plate slot 16 is opened in a square structure. A plurality of spacers 17 are arranged in the plate slot 16, and a spacing distance is set between each spacer 17. The shape and structure of the spacer 17 are adapted to the temperature averaging plates 8, so that the multiple temperature averaging plates 8 are placed in the plate slot 16 in an orderly manner without being closely attached to each other to cause influence.

[0037] Two groups of screw holes 18 are also provided on the top of the collector 7, and the two groups of screw holes 18 are respectively located at the two ends of the plate groove 16, and each group of screw holes 18 is provided with two. A connecting seat 20 is threadedly installed on each group of screw holes 18, which is used to take or place the collector 7 in the rotating drum 6, and acts as a moving tool.

[0038] Specifically, the lifting auxiliary clip 19 is set to a U-shaped structure, and the lifting auxiliary clip 19 is installed in an inverted manner, that is, the two ends of the bottom of the lifting auxiliary clip 19 are respectively detachably contacted on the two connecting seats 20. Its detachable installation method is achieved by setting the connecting seat 20 as a magnet or an iron block. Furthermore, the lifting auxiliary clip 19 is set to a magnet or an iron block that is compatible with the connecting seat 20. If the connecting seat 20 is set to a magnet, the lifting auxiliary clip 19 is set to a magnet or an iron block; if the connecting seat 20 is set to an iron block, the lifting auxiliary clip 19 is set to a magnet. That is, one of the two must be set to a magnet so that the other can be magnetically connected. The magnetic connection method also provides convenience for taking and placing the collector 7.

[0039] A further configuration is that the collector 7 is configured to be made of a soft material, which is conducive to making the outer wall of the collector 7 flexibly contact with the inner wall of the drum 6, and the plate groove 16 on the collector 7 also flexibly contact with the temperature equalizing plate 8, avoiding collision and damage to the temperature equalizing plate 8 when cooperating with the temperature equalizing plate 8.

[0040] In summary, the present invention provides an auxiliary liquid injection device for an ultra-thin temperature equalizing plate 8. By setting up a centrifuge, the traditional manual shaking liquid injection form is replaced by the self-centrifugal liquid absorption effect of the temperature equalizing plate 8, which not only ensures that the temperature equalizing plate 8 can obtain sufficient liquid absorption, but also improves the yield rate. Moreover, multiple rotating drums 6 are integrated on the centrifugal bracket, which can perform centrifugal work on multiple temperature equalizing plates 8 at one time, thereby improving work efficiency.

[0041] The above embodiments show and describe the basic working principle, main technical features and advantages of the present invention. However, the ultra-thin temperature equalizing plate auxiliary liquid injection device designed by the present invention is not limited by the above embodiments, and there will be changes and improvements in various different embodiments. These changes and improvements all fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
