Description

Technical Field

[0001] The present invention relates to the technical field of thermal paste application, and in particular to a thermal paste spreading tool and a thermal paste filler capable of being attached with a thermal paste filler. Background Art

[0002] Thermal paste is a filling type thermal interface material with good thermal conductivity. The material is in paste or liquid form, with a certain viscosity, fluidity and compliance. The application tools and techniques of thermal paste (such as thermal conductive silicone grease, liquid metal) directly affect the heat dissipation effect. Reasonable application methods can ensure that the heat sink is in full contact with the heat source (such as electronic device chips) to reduce contact thermal resistance and avoid overheating. Its ideal gap filling, as well as anti-attenuation durability, anti-drying performance, and anti-pumping performance are the core of effective heat transfer and ensuring the stable operation of electronic devices such as chips. This requires that the thermal paste needs to be removed and replaced after a period of use, especially in the field of DIY application such as high-performance gaming notebooks and desktops. In order to pursue high frame rate and high image quality gaming experience, the replacement of thermal paste is more frequent. Thermal paste needs to be able to be sealed and stored after use to reduce the speed of drying in natural conditions such as solvent evaporation.

[0003] Commonly used pre-filled thermal paste containers include syringes, plastic sealed packaging bags, bottles with lids or barrels with lids, etc. Syringes, such as syringes with caps, are common container types in areas such as DIY disassembly and application. The weight of pre-packaged thermal paste in a syringe is usually in the range of 1g to 5g. For a laptop, the single-use amount is usually around 1g, and for a desktop computer, it is slightly more. If it is not used up at one time, it needs to be capped and sealed for storage.

[0004] In the existing coating technology, on the one hand, the capped syringe can facilitate DIY users to repeatedly implement the dot coating method (single-point or multi-point coating method), straight coating method, cross coating method, or X-shaped coating method, and squeeze the pre-installed thermal paste into the syringe in the form of dots or lines and inject it into the heat source such as the chip surface. However, these coating methods do not spread the extruded thermal paste, but directly use the heat sink to buckle it, so they are more dependent on the buckle and pressurization performance, showing the common thermal paste DIY coating field commonly known as "eating (depending on) buckle performance", and it is difficult to ensure the elimination of air pockets.

[0005] On the other hand, it is preferable to use conventional application tools, such as commonly used plastic scrapers / cards, or disposable finger sleeves, to scrape (or scrape) the thermal paste added to the chip surface by the above coating method, so that the thermal paste can be evenly applied to the chip surface, with as little air pockets as possible and as thin as possible. However, these conventional scraping tools are too single in terms of product structure, function, market, and differentiated value. Moreover, these scraping methods, for example, plastic scrapers, need to be used in a targeted manner according to the characteristics of the thermal paste (such as viscosity or stickiness) and the solid surface characteristics of the heat source and heat sink assembly (such as surface roughness or surface energy), in order to perform their due application function. Therefore, high skills are required in using the scraper; it is difficult for the scraper to form a high-quality uniform layer and a flat surface, and the robustness needs to be improved; the scraped layer is sensitive to the pressure and shear force applied by the scraper, and it is difficult to apply the thermal paste continuously and stably, and it is not easy to spread and thin it quickly, continuously and stably; due to the above reasons, it is difficult to avoid the encapsulation of micro bubbles when the heat sink is assembled and pressed, which to a certain extent suppresses the user's DIY enthusiasm for changing thermal paste.

[0006] It can be seen that pre-packaged thermal paste containers such as capped syringes are usually small in size and are not easy to find when reused; and scrapers and other accessories for thermal paste are short, narrow and thin, and are even smaller in size, and are also not easy to find. It is even more difficult to find both at the same time, but both are indispensable for the application of thermal paste. Therefore, the existing thermal paste application technology has at least the above technical problems that need to be solved. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and beneficial effects of the present disclosure clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments, and the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the technical field without making creative work are within the scope of protection of this application.

[0031] In the absence of conflict, the embodiments, examples and features in the present disclosure may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the examples.

[0032] Specifically, the thermal paste filler can be a syringe-type filler, a bag-shaped container (such as a bag) or a bottle container. Preferably, the thermal paste filler is a syringe-type filler. In the following embodiments, the thermal paste filler is taken as an example of a syringe-type filler.

[0033] In some embodiments, the syringe-type injector has a barrel for accommodating the thermal paste, a narrowed and tapered injection outlet connected to the lower port of the barrel, a sealing piston matched to the inside of the barrel for sealing the thermal paste, and a piston core rod connected to the sealing piston, the head of the piston core rod is located at the upper end and outside of the barrel. The barrel may or may not have a barrel handle. During operation, when the piston core rod is pushed in, the thermal paste is squeezed out from the injection outlet to the surface of the heat source, such as the top surface of the chip.

[0034] Please refer to Figure 1-1 , shows a schematic diagram of the structure of an embodiment of the syringe injector disclosed in the present invention. It includes a syringe injector 1, the upper port 111 of the barrel 11 is connected to a barrel handle 112 extending outward (for holding the syringe injector), the lower port 113 of the barrel 11 is the injection outlet of the barrel 11 (such as a common thin nozzle), the thin nozzle is the extrusion outlet of the thermal paste and the thin nozzle has an adapted pluggable sealing plug 12 (such as a sealing cap), the barrel 11 is also inserted with a piston 13 and a piston push rod 14, and the top of the piston push rod 14 has a piston handle 141. Preferably, the barrel 11 and the piston push rod 14 are selected from plastic materials, and the piston 13 is selected from rubber or silicone materials.

[0035] Please refer to Figure 1-2, showing a schematic structural diagram of an embodiment of the thermal paste spreading tool disclosed in the present invention. As shown in sub-figure (a1) and sub-figure (b1), each includes a thermal paste spreading tool 2, and the thermal paste spreading tool 2 includes a working part 21, a hand-held part 22, and a connecting part 23. The working part 21 includes a roller body 210, the circumferential outer surface of the roller body 210 is used for rolling to spread the thermal paste, and the roller body 210 has a rotation axis OO'; the connecting part 23 is arranged between the working part 21 and the hand-held part 22; the hand-held part 22 is provided with a carrying structure 3, and the carrying structure 3 is used to carry a thermal paste filler pre-loaded with thermal paste. In addition, as shown in sub-figure (a2) and sub-figure (b2), they are cross-sectional structural schematic diagrams of the A-A' section and the B-B' section of sub-figure (a1) and sub-figure (b1), respectively. The A-A' section and the B-B' section both indicate the left and right sides of the hand-held part 22, respectively.

[0036] Among them, the cross-sectional structure of the A-A' section shows a hollow tube body composed of a hand-held portion 22, and the hollow tube body can be used to plug into the barrel of the thermal paste filler, or insert the entire thermal paste filler, and the hollow tube body constitutes a structural type of the attachment structure 3. The hollow tube body can, for example, have the same area of ​​each cross section of the inner cavity, or the area becomes smaller inward to form an anti-slip fastening at the inner end of the inner cavity after plugging; the cross-sectional structure of the B-B' section shows another hand-held portion 22 composed of A handle, the upper part of which is connected to a short tube parallel to each other in an axial direction in a detachable or fixed manner, the short tube is used to plug into the barrel (such as the lower section) of the thermal paste filler or a pluggable sealing plug, the handle can be, for example, a hollow tube, solid, hollow or porous inner cavity, the handle can also be, for example, a square, rectangular, elliptical, plate-shaped or other shapes in cross section other than the circular shape, the handle can also be of variable diameter or equal diameter, or be provided with a through hole or the outer shell is provided with a hollow hole.

[0037] In addition, it should be pointed out and explained that in another embodiment, the thermal paste spreading tool 2 may only include the working portion 21 and the connecting portion 23, but not necessarily the hand-held portion 22, which is beneficial in the following embodiments (such as Figure 2-2 In another embodiment, the connection portion 23 and the handle portion 22 of the thermal paste spreading tool 2 are integrally formed.

[0038] Optionally, the attachment method of the attachment structure includes a detachable connection or a fixed connection. The fixed connection in the present disclosure is relative to the detachable connection, and the fixed connection is a non-detachable connection; and the detachable connection and the non-detachable connection can be a movable connection or a non-movable connection. The corresponding embodiments and their integrated effects can be referred to respectively. Figure 2-1 , Figure 2-2 .

[0039] like Figure 2-1 , showing a schematic diagram of an integrated effect of a thermal paste spreading tool with a detachable connection. As shown in sub-figure (a) and sub-figure (b), both include a syringe-type injector 1 and a thermal paste spreading tool 2. It can be seen that the syringe-type injector 1 constitutes a syringe-type injector, and the hand-held portion of the thermal paste spreading tool 2 constitutes a handle, and the handle constitutes a hollow tube body with an upper port, and the hollow tube body constitutes a pluggable attachment structure, and then the barrel of the syringe-type injector can be inserted into the hollow tube body from the upper port to obtain a pluggable attachment method.

[0040] It can be further improved that the barrel of the syringe-type injector 1 and the hollow tube of the thermal paste spreading tool 2 form a plug-in connection adapter, for example, after the barrel is inserted into the hollow tube, the hollow tube can form a certain annular pressing pressure on the barrel, or form a friction force between the contact surface of the hollow tube and the barrel, so that the barrel will not easily fall out of the handle.

[0041] It needs to be explained and illustrated that for the detachable connection, if the attachment needs to be released after the attachment is completed, the attachment structure between the syringe-type filler and the thermal paste spreading tool can, for example, be released in a destructive manner, or can preferably be released in a non-destructive manner based on elastic deformation.

[0042] like Figure 2-2 , showing a schematic diagram of an integrated effect of a thermal paste spreading tool including a fixed connection. As shown in sub-figure (a) and sub-figure (b), both include a syringe-type filler 1 and a thermal paste spreading tool 2. Among them, the syringe-type filler 1 constitutes a syringe-type filler. It can be seen that the top of the pluggable sealing plug is connected to the top of the connecting portion 23 included in the thermal paste spreading tool 2 in the form of a fixed connection. The advantage is that the thermal paste spreading tool 2 can only include a working portion 21 and a connecting portion 23, and the barrel 11 of the syringe-type filler 1 can be regarded as and used as a hand-held portion of the thermal paste spreading tool 2, and there is no need to set up an additional hand-held portion (such as a handle).

[0043] Need to explain and illustrate, such as Figure 2-2 The top of the pluggable sealing plug 12 in the thermal paste spreading tool 2 may also be connected to the top of the connection portion 23 included in the thermal paste spreading tool 2 in a detachable connection form instead of a fixed connection. For example, the top of the pluggable sealing plug 12 is connected to the top of the connection portion 23 in a detachable connection form such as a plug connection or a threaded connection. The detachable assembly thus obtained has a high structural robustness.

[0044] Above Figure 2-1 and Figure 2-2The embodiment has the benefit of realizing the structural association and functional coordination between the thermal paste spreading tool and the thermal paste injector, and facilitating space-saving storage, transportation, delivery, and user access and storage. It can be seen that the product line of thermal paste and its injector and application tool is enriched, and the differentiated value and sales of thermal paste, thermal paste injector and / or thermal paste spreading tool can be promoted, so that the thermal paste spreading tool has uniqueness and identity.

[0045] For example, get Figure 2-1 The hollow tube handle can also save materials and easily meet the necessary thickness of the handle to better meet the ergonomics of holding. Figure 2-2 The thermal paste spreading tool in the device regards the barrel of the syringe dispenser as and serves as the handle (no need to configure a special handle additionally), which further saves materials and is environmentally friendly.

[0046] It needs to be explained and illustrated that the thermal paste spreading tool in the present disclosure realizes the function of being able to carry a thermal paste filler with an attachment structure. It can be attached with (i.e., integrally connected with) a thermal paste filler, or it can be not attached with (i.e., not connected with) a thermal paste filler.

[0047] Therefore, one product form of the thermal paste spreading tool in the present disclosure is: a thermal paste spreading tool with a thermal paste filler attached (i.e., connected integrally). It can achieve structural association and functional coordination that both are used for thermal paste, but the former is used for spreading and the latter is used as a container, and then the thermal paste filler is attached to form the unique function of the thermal paste spreading tool of the present disclosure, thereby obtaining the uniqueness and identification of the thermal paste spreading tool of the present disclosure; it can also achieve convenient access to the thermal paste filler, and convenient storage with reduced possibility of loss; it can also achieve convenient delivery of both.

[0048] Another product form of the thermal paste spreading tool in the present disclosure is: a thermal paste spreading tool without a thermal paste injector attached (i.e., not connected). This allows, for example, a user to purchase a thermal paste spreading tool without a thermal paste injector attached. This means that if the user has, for example, an old syringe injector, the syringe injector can be attached to the thermal paste spreading tool, thereby obtaining a detachable assembly of the two, which can reduce the possibility of loss of the syringe injector and facilitate storage, and improve the convenience of applying thermal paste later.

[0049] It is also necessary to explain and illustrate that the attachment method of the attachment structure includes a detachable connection or a fixed connection; or, the attachment method of the attachment structure is a detachable connection, and the detachable connection includes a snap connection, threaded connection, key connection, pin connection, plug-in connection, plug-in accommodation, quick connector, flange connection, clamping connection, cable tie connection, adhesive connection, negative pressure adsorption connection, magnetic connection or mortise and tenon connection. This means that it should be understood that in order to realize that the attachment structure can be attached to the thermal paste injector, in some embodiments, the corresponding attachment structure requires at least one set of matching parts for realizing the connection, which can be defined as a female matching part and a sub-matching part, wherein the female matching part is attached to the handheld part (or the connecting part), and the sub-matching part is attached to the thermal paste injector, or the female matching part is attached to the thermal paste injector, and the sub-matching part is attached to the handheld part (or the connecting part). For example, the threaded connection requires bolts and screws as female matching parts and sub-matching parts respectively. For example, the sub-matching part can be a barrel, a pluggable sealing plug or a piston handle that is fixedly connected or detachably connected to the thermal paste injector, so the sub-matching part can be a syringe attached to an existing thermal paste container type to form a syringe-type injector; In other embodiments, the corresponding attachment structure requires a matching piece for connection, and the matching piece is attached to the handheld portion (or the connecting portion), for example Figure 2-1 The hollow tube 211 of the thermal paste spreading tool 2 can be regarded as a matching part for achieving connection, but it is easy to understand that the barrel 11 of the syringe-type injector 1 as an insert can be regarded as the above-mentioned sub-matching part, and the hollow tube 211 of the thermal paste spreading tool 2 can be regarded as the above-mentioned female matching part, so the existing thermal paste container type syringe can constitute another syringe-type injector. It can be seen that these different implementations actually have differences and uniformities.

[0050] For example, snap connection, snap is to fix two or more parts together by clamping the specific part of the object. It can rely on the characteristics of the elastic material, by matching with the notch, hole or groove of the connected object, firmly fix the connecting part without the need for other auxiliary tools or equipment. The elastic material can match with the notch, hole or groove to form a loading structure, in which the elastic material can be regarded as a sub-matching part, and the notch, hole or groove can be regarded as a female matching part; or the elastic material can be regarded as a female matching part, and the notch, hole or groove can be regarded as a sub-matching part. For example, if the elastic material is used as a sub-matching part, the sub-matching part can be fixedly connected or detachably connected to the thermal paste dispenser. The snap connection method is generally considered to be an efficient and simple connection method. Especially in some environments with low installation accuracy requirements or limited operating space, the snap connection method has unique advantages.

[0051] In order to make these embodiments clearer and easier to understand, the preferred attachment structure is described in detail below with reference to the accompanying drawings.

[0052] Please refer to Figure 3-1 , wherein sub-figure (a1) shows a schematic structural diagram of a plug-in connection of a thermal paste spreading tool, including a syringe-type filler 1, a thermal paste spreading tool 2 and an inner lining 31, wherein the inner lining 31 is, for example, a convex rib on the inner wall of a hollow tube of a hand-held portion, and the convex rib forms a radial tightening and / or axial friction force when the thermal paste filler is inserted, thereby preventing the barrel of the thermal paste filler from easily falling out of the hollow tube of the handle; and, sub-figure (a2) shows a schematic structural diagram of the C-C' section. And, sub-figure (b1) shows a schematic structural diagram of a snap connection of a thermal paste spreading tool, showing a syringe-type injector 1 and a thermal paste spreading tool 2; and, sub-figure (b2) shows a schematic structural diagram of the D-D' section, showing that the barrel of the syringe-type injector 1 is seated in the snap groove of the thermal paste spreading tool 2, and further, the barrel of the syringe-type injector 1 can be inserted into the snap groove in the form of a plug-in connection from the upper port opened by the hand-held part, or can be seated (for example, inserted into the accommodating) from the hand-held part and the side of the snap groove to achieve the snap groove accommodating the barrel. It can be regarded as that all or part of the barrel of the syringe-type injector 1 can be attached to the inner periphery of the hand-held part of the thermal paste spreading tool 2.

[0053] In some similar embodiments, the handheld portion is configured as a handle of the syringe dispenser that can be seated on one side, and the handle is used to allow the barrel or the syringe dispenser to form the insertion accommodation in whole or in part. For example, a slot capable of accommodating a thermal paste dispenser (e.g., a syringe dispenser) is provided on the side of the handheld portion; the slot can optionally extend and pass through the upper end of the handheld portion; the slot can also extend but not pass through the upper end of the handheld portion, so that the upper end of the handheld portion can be conveniently coupled to, for example, a pre-spreading auxiliary tool in the form of a fixed connection or a detachable connection.

[0054] In the disclosed embodiment, the upper end of the hollow tube of the thermal paste spreading tool is preferably coupled with a restraining structure for preventing the barrel from falling off easily when inserted into the barrel. For example, the restraining structure may be an elastic ring plug that can be stretched open; or the inner wall of the hollow tube is provided with elastically deformable ribs extending along the radial section; or an elastic outer lining is provided on the barrel of a syringe-type injector, etc.

[0055] In the disclosed embodiment, the slot of the handheld portion of the thermal paste spreading tool is preferably coupled with a restraining structure for preventing the barrel from falling off easily when the barrel is inserted. For example, the restraining structure can be a handheld portion shell constituting the slot, and the handheld portion shell can, for example, form an inward elastic force after being stretched open; or the slot has a snap-fit ​​structure for the barrel handle; or there is a sticky layer in the slot; or there is a snap-fit ​​structure in the slot, etc. Please refer to Figure 3-2, wherein sub-figure (a1) shows a schematic diagram of the plug-in connection structure of a thermal paste spreading tool, showing that it includes a syringe-type filler 1, a thermal paste spreading tool 2 and an attachment structure 3, and sub-figure (a2) shows a schematic diagram of the cross-sectional structure of its E-E' section. Sub-figure (b1) shows a schematic diagram of the snap-on connection structure of a thermal paste spreading tool, showing that it includes a syringe-type filler 1, a thermal paste spreading tool 2 and an attachment structure 3, and sub-figure (b2) shows a schematic diagram of the cross-sectional structure of its F-F' section. It can be seen that the barrel of the syringe-type filler 1 is seated in the snap-on groove of the thermal paste spreading tool 2. It can be regarded as that the syringe-type filler 1 is attached to the periphery (e.g., the upper part) of the handheld portion of the thermal paste spreading tool 2.

[0056] It is also understandable. Figure 3-2 In sub-figure (a2) and sub-figure (b2), the hand-held part of the thermal paste spreading tool 2 shown constitutes a hollow tube body, which can be replaced by, for example, a solid handle, a handle with a porous inner cavity, and its cross-section can be square, rectangular, elliptical, plate-shaped or other shapes in addition to the circular shape shown.

[0057] Please refer to Figure 3-3 , wherein sub-figure (a) shows a schematic diagram of the plug-in connection structure of a thermal paste spreading tool, showing that it includes a syringe-type filler 1, a thermal paste spreading tool 2 and an attachment structure 3, specifically, the pluggable sealing plug (such as a sealing cap) of the syringe-type filler 1 is connected to the hole of the attachment structure 3 in the form of a plug-in connection attachment. Sub-figure (b) also shows a schematic diagram of the plug-in connection structure of a thermal paste spreading tool, showing that it includes a syringe-type filler 1, a thermal paste spreading tool 2 and an attachment structure 3. It can be seen that the handheld portion and the connecting portion of the thermal paste spreading tool can be set at a certain angle to obtain different usage experiences and effects.

[0058] It can also be supplemented that, exemplarily, the tube body of the handheld portion of the thermal paste spreading tool may have a straight axis, or a partially broken line or curved axis. In addition, exemplarily, the handheld portion may be constructed to be retractable. Optionally, the circumferential cross-section of the barrel of a syringe-type filler may be circular or elliptical, etc., and may also be of equal diameter or variable diameter. Optionally, the outer surface of the thermal paste filler (such as the top, bottom or body of the device, etc.) may be fixedly connected to the connecting portion. Optionally, the roller body of the thermal paste spreading tool may be replaced by a ball body. The hollow tube body should be regarded as one of the aforementioned tube bodies.

[0059] In summary, the disclosed embodiment realizes the structural association and functional coordination between the thermal paste spreading tool and the thermal paste filling device, so that the thermal paste spreading tool has uniqueness and identity. It also promotes the differentiated value and sales of the thermal paste spreading tool and the thermal paste, and improves the user experience, making storage, transportation and delivery easier, and satisfying the user's need for access and storage based on attachment (or mounting).

It should be explained and understood that, optionally, the thermal paste spreading tool may refer to the thermal paste spreading tool in the first aspect, and the thermal paste spreading tool may or may not have an attachment structure.

Optionally, the syringe-type filler in the second aspect and its embodiments may be the same as the syringe-type filler in the first aspect and its embodiments.

[0061] In another aspect of the present disclosure, a thermal paste filler is provided, which has a second attachment structure; the second attachment structure is used to cooperate with the first attachment structure on the thermal paste spreading tool, so that the thermal paste filler is connected to the thermal paste spreading tool in a fixed or detachable attachment manner. Preferably, the thermal paste filler is a syringe-type filler. Optionally, the thermal paste spreading tool can refer to the above.

[0062] In another aspect of the present disclosure, there is provided a pre-spreading auxiliary tool capable of carrying a thermal paste filler, the pre-spreading auxiliary tool comprising: a third working piece having a third working surface on its outer surface, the third working surface being configured as a convex third curved surface, the two principal curvatures of the third curved surface being both positive numbers, and a third hand piece for manually controlling the pre-spreading auxiliary tool so that the third working part presses and / or rolls the thermal paste, and a third connecting piece for connecting the third working piece and the third hand piece in a fixed or movable connection, and the third hand piece or the third connecting piece is provided with a third carrying structure for carrying the thermal paste filler pre-loaded with thermal paste, or, A third working piece, whose outer surface has a third working surface, the third working surface is constructed as a convex third curved surface, and the two main curvatures of the third curved surface are both positive numbers, and a third connecting piece is used to be connected to the third working piece in the form of a fixed connection or a movable connection, and the third connecting piece is provided with a third attachment structure for attaching the thermal paste filler pre-installed with thermal conductive paste.

[0063] Preferably, the pre-spreading auxiliary tool comprises: the third curved surface is constructed as a third spherical surface.

[0064] Furthermore, the pre-spreading auxiliary tool includes: the third spherical surface is contained in a third sphere.

[0065] It is necessary to explain and illustrate that the third working piece should be understood as the working part of the pre-spreading auxiliary tool, the third hand piece should be understood as the hand piece of the pre-spreading auxiliary tool, and the third connecting piece should be understood as the connecting part of the pre-spreading auxiliary tool. This description is only to more clearly distinguish the working part, hand piece and connecting part contained in the aforementioned thermal conductive paste spreading tool that can be equipped with a thermal conductive paste injector.

[0066] In another aspect, the present disclosure provides a thermal paste spreading tool, comprising: a working part, the working part having a roller-shaped outer shell layer, the outer surface of the roller-shaped outer shell layer serving as a working surface for rolling and / or pressing the thermal paste, the working part also having an inner sleeve core for fitting in the roller-shaped outer shell layer and being able to support the roller-shaped outer shell layer; a hand-held part for hand-holding and braking the thermal paste spreading tool so that the working surface forms the rolling and / or pressing; a connecting part for forming a movable connection between the working part and the hand-held part so that the working surface forms the rolling and / or pressing. Optionally, the inner sleeve core is obtained by 3D printing or injection molding. Exemplarily, the inner sleeve core can be of regular shape or irregular shape, for example, the contact surface between the inner sleeve core and the working surface has an uneven interlocking structure or a spacing support structure. Preferably, the working surface of the roller-shaped outer shell layer is non-sticky. Preferably, the roller-shaped outer shell layer is constructed as a roller-shaped outer shell layer made of polytetrafluoroethylene. Preferably, the working surface of the roller-type outer shell layer has non-stick properties, which are formed by a non-stick coating. Preferably, the rolling and / or rolling can be performed repeatedly, such as repeated rolling. Optionally, the thermal paste spreading tool has or does not have the attachment structure. Optionally, the thermal paste spreading tool may also include a heating device, which is used to allow the working surface to obtain heat to heat the contacted thermal paste during work, thereby enhancing the spreading, such as enhancing the rolling and / or rolling. Preferably, the heating device includes a heating portion, which is arranged on the inner periphery of the cylindrical smooth working surface. Optionally, the heating device is powered by a connected power cord or battery.

[0067] See also Figure 4-1, showing a schematic diagram of the integrated effect of a thermal paste spreading tool that also includes a pre-spreading auxiliary tool. It is shown that it includes a thermal paste spreading tool 2 and a pre-spreading auxiliary tool 4. The handheld part of the thermal paste spreading tool 2 is a hollow tube body, and the hollow tube body has an upper port that can be inserted into a syringe-type injector; the pre-spreading auxiliary tool 4 includes a working piece 41 and a connecting piece 42, and the working piece 41 is specifically a sphere, and the upper end of the connecting piece 42 is connected to the upper port of the handheld part of the thermal paste spreading tool 2 in the form of a fixed connection or a detachable connection. It can be seen that the thermal paste spreading tool includes the pre-spreading auxiliary tool, which as a whole constitutes a multifunctional composite tool with a roller body and a sphere.

[0068] In particular, the pre-spreading auxiliary tool, by constructing a curved surface with a limited curvature feature as a working surface, when it acts on the paste in a pressing and / or rolling manner, it exhibits stronger non-stick properties compared to spreading tools of the same material, such as cylindrical rollers or scrapers. The limited curved surface structure of this tool is mainly used for the initial spreading of the paste. After rolling, the paste is locally flattened and dense, and a micro-pit array is formed where the thermal paste is partially pressed into the heat source, such as the chip surface, thereby achieving the effect of initially eliminating cavitation. After that, the final rolling and spreading can be easily completed by using a cylindrical roller, and the thermal paste is no longer easily picked up by the roller body in blocks or sheets. Therefore, the pre-spreading auxiliary tool is a geometric structure with relatively non-stick properties that is suitable for spreading thermal paste.

[0069] This non-stick effect does not come from the surface coating, plating or modification of the material, but only from the modification of the geometric structure, thus saving the processing cost that would otherwise be invested in the roller surface. And after coupling the non-stick coating, a more obvious effect will be obtained, and the subsequent use of the roller body will make it easier to achieve more efficient and high-quality thermal paste spreading. In addition, in terms of production, the existing industrial manufacturing method can produce the curved surface or structure required by the present disclosure with high efficiency, high quality and low cost.

[0070] See also Figure 4-2 , showing a schematic diagram of the integrated effect of the pre-spreading auxiliary tool being connected to the thermal paste spreading tool in a detachable manner, and a syringe-type injector is attached in a plug-in manner. The figure shows a thermal paste spreading tool 2 and a pre-spreading auxiliary tool 4. The hand-held portion of the thermal paste spreading tool 2 is a hollow tube body, and the hollow tube body has an upper port into which a syringe-type injector can be inserted, and the hollow tube body can be plugged to accommodate the syringe-type injector; the pre-spreading auxiliary tool 4 includes a working piece 41 and a connecting piece 42, and the working piece 41 is specifically a sphere, and the upper end of the connecting piece 42 is connected to the upper port of the hand-held portion of the thermal paste spreading tool 2 in the form of a plug-in connection.

[0071] It can be seen that Figure 4-2The embodiment constitutes a multifunctional composite tool with a roller body and a spherical body as a whole, and the hollow tube body is equipped with a syringe-type injector in a plug-in manner, so that the thermal paste spreading tool and the thermal paste injector can achieve structural association and functional coordination, making the thermal paste spreading tool unique and identifiable. It also has the benefits of promoting the differentiated value and sales of the thermal paste spreading tool and the thermal paste, and improving the user experience, making it easy to store, transport and deliver, and satisfying the user's access and storage based on the integrated attachment (or mounting).

[0072] In a similar embodiment, the handheld portion of the thermal paste spreading tool 2 has the aforementioned slot, and the syringe-type injector can be seated (e.g., inserted and accommodated) in the slot from the side of the handheld portion. The slot can be opened on the basis of the hollow tube body, and the hollow tube body can have the upper port or not have the upper port; or the slot can be added on the basis of the non-hollow tube body, and the slot can extend and pass through the upper end of the handheld portion (or extend but not pass through the upper end of the handheld portion).

[0073] In addition, it should be clarified that for the pre-spreading auxiliary tools with a hollow tube body, in addition to being able to be plugged in or inserted into the hollow tube body to accommodate the attached thermal paste filler, it can also replace (or simultaneously) carry small devices required for DIY manual replacement of thermal paste and simultaneous cleaning, such as scrapers, screwdrivers, pry bars, cleaning wipes, finger cots, thermal pads, etc.

[0074] It should be explained and illustrated that the first working piece and the second working piece may have the same or different specific structures in different (or the same) embodiments, and both should be understood as working modules (or parts used for work) of the pre-spreading auxiliary tool. Similarly, the first connecting piece and the second connecting piece may have the same or different specific structures in different (or the same) embodiments, and both should be understood as connecting modules (or parts used for connection) of the pre-spreading auxiliary tool.
