Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a radiator insulating sheet positioning device. Background Technology

[0002] Insulating sheets isolate heat-generating components from heat sinks, preventing accidental current conduction and avoiding dangers such as short circuits and leakage. For example, in the power supply module of a computer motherboard, insulating sheets separate power components from the metal heat sink, thereby ensuring the safe and stable operation of the circuit. However, the traditional method of attaching Mylar sheets is as follows: peel off the protective adhesive layer on the Mylar sheet, align the round holes of the Mylar sheet with the mounting holes on the heat sink, and attach it. However, in actual operation, due to the softness of the Mylar sheet material, the 3M adhesive on the back, and the large number of holes that need to be positioned, manually attaching the Mylar sheet to the heat sink can lead to problems such as inaccurate positioning, long operation time, and easy damage. In view of this, a heat sink insulating sheet positioning device that can solve the above problems is proposed. Utility Model Content

[0003] To solve the technical problem of inaccurate positioning when attaching insulating sheets to radiators, this utility model provides a radiator insulating sheet positioning device.

[0004] This utility model is achieved using the following technical solution: a radiator insulating sheet positioning device, including a base plate, a base fixedly connected to the upper side of the base plate, a placement cavity opened on the upper side of the base, a plurality of vacuum holes opened on the bottom side of the placement cavity, a plurality of positioning bosses fixedly connected to the bottom side of the placement cavity, a negative pressure leveling mechanism opened on the lower side of the base, and an adhesive mechanism provided on the upper side of the placement cavity.

[0005] With the above technical solution, the insulating sheet can be directly placed into the placement cavity, and the groove-shaped structure of the placement cavity can be used to position the insulating sheet. Furthermore, the air under the insulating sheet can be extracted by a vacuum pump through the vacuum hole, and the negative pressure can be used to form an adsorption force for shaping, thereby improving the bonding quality.

[0006] As a further improvement to the above solution, the negative pressure leveling mechanism includes a vacuum chamber opened on the lower side of the base, a base plate is fixedly connected to the lower side of the base, and a vacuum pumping mechanism is provided on one side of the base.

[0007] As a further improvement to the above solution, the vacuum pumping mechanism includes a quick-connect duct connector fixedly connected to one side of the base, the quick-connect duct connector communicating with the inside of the vacuum chamber, and one end of the quick-connect duct connector being connected to a vacuum pump.

[0008] The above technical solution allows for the removal of air from the vacuum chamber and the creation of a negative pressure environment by connecting a vacuum pump to a quick-connect fitting for the air pipe.

[0009] As a further improvement to the above solution, the pasting mechanism includes a Mylar sheet disposed in the placement cavity, the Mylar sheet having a positioning hole that cooperates with the positioning boss, and a heat sink docking mechanism disposed on the upper side of the Mylar sheet.

[0010] The above technical solution facilitates accurate positioning through the cooperation of the positioning hole and the positioning boss.

[0011] As a further improvement to the above solution, the radiator docking mechanism includes a heat dissipation substrate that is configured to cooperate with the upper side of the Mylar plate. Multiple radiator fins are fixedly connected to the upper side of the heat dissipation substrate, and the multiple radiator fins are arranged in a linear array.

[0012] With the above technical solution, after peeling off the protective layer on the insulating sheet, the heat dissipation substrate can be directly attached to the adhesive backing of the Mylar sheet. By gently pressing, an adhesive can be formed. Moreover, with the cooperation between the heat dissipation substrate and the placement cavity, the bonding position accuracy is high.

[0013] As a further improvement to the above scheme, the number of positioning bosses is not less than one.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model connects to a vacuum pump via a quick-connect tubing connector. Through the vacuum port, a vacuum operation is performed on the space below the Mylar sheet placed inside the placement cavity to create a negative pressure space, allowing the Mylar sheet to fully expand and flatten. Furthermore, with the assistance and correction of multiple positioning bosses, the positional accuracy can be guaranteed when the heat dissipation substrate is attached to the upper side of the Mylar sheet.

[0016] 2. When applying insulating sheets to a radiator using this utility model, simply place the insulating sheet into the placement cavity, then start the vacuum pump through the quick connector of the air pipe to create negative pressure, and then attach the heat sink substrate to the upper side of the insulating sheet to achieve precise bonding. The operation is simple, convenient, and efficient. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figures 1-3 The radiator insulating sheet positioning device of this embodiment includes a base plate (5) and a base (3) fixedly connected to the upper side of the base plate (5). In this embodiment, the base (3) is a rectangular structure that is adapted to the size of the radiator insulating sheet.

[0027] Please combine Figure 1 As shown, a placement cavity (7) is provided on the upper side of the base (3). It should be noted that the layout of the placement cavity (7) matches the structural features of the insulating sheet required by the heat sink, which facilitates overall placement and precise positioning.

[0028] Please combine Figure 5 As shown, multiple vacuum holes (10) are provided on the bottom side of the placement cavity (7). The vacuum holes (10) are circular holes and are distributed in a matrix, which facilitates the removal of air from the insulating sheet from the bottom and the formation of negative pressure.

[0029] Please combine Figure 4 As shown, multiple positioning bosses (9) are fixedly connected to the bottom side of the placement cavity (7). The positioning bosses (9) are conical structures. With the cooperation of the seven positioning bosses (9), it is convenient to adjust the placement position of the insulating sheet in the placement cavity (7).

[0030] Please combine Figure 4 As shown, a negative pressure leveling mechanism is provided on the lower side of the base (3), and an adhesive mechanism is provided on the upper side of the placement cavity (7).

[0031] Please combine Figure 3As shown, the negative pressure leveling mechanism includes a vacuum chamber (8) opened on the lower side of the base (3). The vacuum chamber (8) is a groove opened at a specific depth on the lower side of the base (3). When the vacuum pump 8 is started, the air in the vacuum chamber 8 can be drawn away and a vacuum negative pressure is formed. The vacuum negative pressure is drawn from the vacuum holes (10) evenly distributed on the lower side of the insulating sheet, adsorbing the lower side of the insulating sheet, so that the insulating sheet is more stretched and flat, and the effect of the insulating sheet is better and the position is more accurate.

[0032] Please combine Figure 3 As shown, a base plate (5) is fixedly connected to the lower side of the base (3), and a vacuum mechanism is provided on one side of the base (3). In this embodiment, the base plate (5) is fixedly connected to the edge of the base (3) by multiple bolts. The base plate 5 is a rectangular structure and made of stainless steel.

[0033] Please combine Figure 2 As shown, the vacuum pumping mechanism includes a quick-connect pipe connector (4) fixedly connected to one side of the base (3). The quick-connect pipe connector (4) is connected to the vacuum pump through a stainless steel pipe. The quick-connect pipe connector (4) is connected to the inside of the vacuum chamber (8). One end of the quick-connect pipe connector (4) is connected to the vacuum pump. A vacuum pump start / stop switch is provided on one side of the base (3). The vacuum pump is started after the insulating sheet is placed into the placement chamber (7). After the insulating sheet is adsorbed and positioned, the heat dissipation substrate (6) is placed in and pressed. Then the quick-connect pipe connector (4) is closed.

[0034] Please combine Figure 2 As shown, the adhesive mechanism includes a Mylar sheet (2) placed in the placement cavity (7). The Mylar sheet is an insulating material made of PET polyester film as the base material. It has excellent electrical insulation properties, mechanical strength and chemical corrosion resistance, and can prevent accidental current conduction and avoid dangers such as short circuits and leakage.

[0035] Please combine Figure 2 As shown, the Mylar sheet (2) has a positioning hole, which is matched with the positioning boss (9). A heat sink docking mechanism is provided on the upper side of the Mylar sheet (2).

[0036] Please combine Figure 2 As shown, the heat sink docking mechanism includes a heat sink substrate (6) that is fitted to the upper side of the Mylar sheet (2). It is made of aluminum, has a rectangular structure, and has excellent thermal conductivity.

[0037] Please combine Figure 2 As shown, multiple heat sink fins (1) are fixedly connected to the upper side of the heat sink substrate (6). The multiple heat sink fins (1) are arranged in a linear array. The heat dissipation area can be expanded through the multiple heat sink fins (1), and they can fully contact the outside cold air to accelerate the heat dissipation efficiency.

[0038] Please combine Figure 2As shown, the number of positioning bosses (9) is not less than 2. In this embodiment, there are a total of 7 positioning bosses (9).

[0039] The implementation principle of the heat sink insulating sheet positioning device in this embodiment is as follows: The quick connector 4 of the air pipe is connected to the vacuum pump. First, the vacuum pump is turned off. The Mylar sheet 2 is held and its front side is placed in the placement cavity 7 of the base 3. Then, the vacuum pump switch connected to the quick connector 4 of the air pipe is turned on, and a negative pressure space is formed in the vacuum cavity 8 between the base 3 and the bottom plate 5. The negative pressure makes the Mylar sheet 2 and the bottom surface of the placement cavity 7 of the base 3 fit tightly through the vacuum hole 10 of the base 3. The backing adhesive protective layer on the back of the Mylar sheet 2 is peeled off. Then, the heat sink substrate 6 of the heat sink is placed face down into the placement cavity 7 of the base 3 and slightly pressed. The vacuum pump switch of the quick connector 4 of the air pipe is turned off. The heat sink fins 1 and Mylar sheet 2 are taken out. At this time, the two parts have been glued together by the backing adhesive, realizing the effect of attaching the insulating sheet.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
