Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of thermal paste application, in particular to a thermal paste spreading tool with a thermal paste dispenser and a thermal paste dispenser. BACKGROUND

[0002] Thermal paste is a kind of filling type thermal interface material with good thermal conductivity, which is in paste or liquid state, has certain viscosity, fluidity and compliance. The application tool and technique of thermal paste (such as thermal silicone grease, liquid metal) directly affect the heat dissipation effect. Reasonable application method can ensure that the heat sink is in full contact with the heat source (such as electronic device chip) to reduce the contact thermal resistance and avoid overheating. Its ideal gap filling, as well as anti-degradation durability, anti-drying performance and anti-pumping performance, are the core of effective heat transfer and stable operation of electronic devices such as chips. Therefore, it is required that the thermal paste needs to be removed and replaced after a period of use, especially in the DIY application field of high-performance game notebooks and desktops. In order to pursue high frame rate and high definition game experience, the replacement of thermal paste is more frequent. After use, the thermal paste needs to be sealed and stored to reduce the speed of drying in natural state caused by solvent evaporation.

[0003] Commonly used pre-loaded thermal paste containers include syringes, plastic sealed packaging bags, capped bottles or capped barrels, etc. Among them, the syringe, such as the capped syringe, is a common container type in fields such as DIY disassembly and application. The weight of the pre-packaged thermal paste in the syringe is usually in the range of 1g to 5g. For notebook computers, the single use amount is usually about 1g, and for desktop computers, it is a little more, and the remaining amount needs to be sealed and stored after use.

[0004] The existing application technology, on the one hand, the capped syringe can be used by DIY users to repeatedly implement point application method (single point or multi-point application method), linear application method, cross application method or X application method to extrude the pre-loaded thermal paste from the syringe and inject it to the surface of the heat source such as chip. However, these application methods do not spread the extruded thermal paste, but directly use the heat sink to press, which depends on the performance of the buckle and press, and is commonly known as "eating (depending on) buckle performance" in the DIY application field of common thermal paste, and it is difficult to ensure that the air cavity is excluded.

[0005] On the other hand, the conventional application tools, such as the commonly used plastic spatula / card or disposable finger sleeve, are preferably used to spread (or spread) the thermal paste on the chip surface filled by the above coating method, so that the thermal paste can be evenly coated on the chip surface as thin as possible, and air bubbles can be excluded as much as possible. However, these conventional application tools are too single in product structure, function and market, and differentiated value. And these application methods, for example, plastic spatula, need to develop specific usage according to the characteristics of the thermal paste (such as consistency or adhesion) and the solid surface characteristics of the heat source and heat sink assembly (such as surface roughness or surface energy) in order to exert its application function, so the use of spatula requires high skill; it is difficult to form a high-quality uniform layer and a flat surface, and the robustness needs to be improved; the pressure and shear force of the application layer on the spatula are sensitive, and it is difficult to continuously and stably apply the thermal paste, and it is not easy to quickly, continuously and stably spread and thin; due to the above reasons, it is difficult to avoid the closure of micro-bubbles during the clamping of the heat sink assembly, which to some extent inhibits the DIY enthusiasm of users to replace the thermal paste.

[0006] It can be seen that the pre-packaged thermal paste container such as a capped syringe is usually small in size, so it is not easy to find when it is used again; and the spatula and other thermal paste accessories are short, narrow and thin in size, so they are also not easy to find. It is even more difficult to find both at the same time, but both are indispensable for thermal paste application. Therefore, the existing thermal paste application technology at least has the technical problems to be solved as described above. Invention content

[0056] To make the objectives, technical solutions, and beneficial effects of this disclosure clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the described embodiments are merely some embodiments of this application, not all embodiments. The specific embodiments described herein are merely illustrative of this application and are not intended to limit this application. All other embodiments obtained by those skilled in the art based on the embodiments in this disclosure without creative effort are within the scope of protection of this application.

[0057] Where there is no conflict, the implementation methods, embodiments, and features therein in this disclosure can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0058] Specifically, the thermal paste applicator can be a syringe-type applicator, a bag-shaped container (e.g., with a bag), or a bottle-type container. Preferably, the thermal paste applicator is a syringe-type applicator. In the following embodiments, the thermal paste applicator is described using a syringe-type applicator as an example.

[0059] In some embodiments, the syringe-type applicator has a barrel containing thermal paste, a narrowed dispensing outlet communicating with a lower port of the barrel, a sealing piston fitted inside the barrel for sealing the thermal paste, and a piston rod connected to the sealing piston, the head of the piston rod located at the upper end and outside of the barrel. The barrel may or may not have a handle. During operation, as the piston rod is pushed in, it extrudes the thermal paste from the dispensing outlet onto the surface of a heat source, such as the top surface of a chip.

[0060] Please refer to Figure 1-1This diagram illustrates a structural schematic of an embodiment of the syringe-type dispensing device disclosed herein. It includes a syringe-type dispensing device 1, whose upper port 111 is connected to an outwardly extending handle 112 (for easy gripping of the syringe-type dispensing device), and its lower port 113 serving as the dispensing outlet (such as a common type of narrow nozzle). The narrow nozzle is an extrusion port for thermal grease and has a suitable pluggable sealing plug 12 (such as a sealing cap). A piston 13 and a piston rod 14 are also inserted within the syringe 11, with a piston handle 141 at the top of the piston rod 14. Preferably, the syringe 11 and piston rod 14 are made of plastic, and the piston 13 is made of rubber or silicone.

[0061] Please refer to Figure 1-2 The diagram illustrates a structural schematic of an embodiment of the thermal paste spreading tool disclosed herein. As shown in sub-figures (a1) and (b1), both include a thermal paste spreading tool 2, which comprises a working part 21, a handheld part 22, and a connecting part 23. The working part 21 includes a roller body 210, the outer circumferential surface of which is used for rolling to spread the thermal paste, and the roller body 210 has a rotation axis OO'. The connecting part 23 is located between the working part 21 and the handheld part 22. The handheld part 22 is provided with a support structure 3 for supporting a pre-filled thermal paste applicator. Furthermore, sub-figures (a2) and (b2) are schematic cross-sectional views of sections A-A' and B-B' of sub-figures (a1 and b1), respectively. Sections A-A' and B-B' indicate the left and right sides of the handheld part 22, respectively.

[0062] The cross-sectional structure of section A-A' shows a hollow tube formed by a handle 22. This hollow tube can be used to insert into the body of a thermal paste applicator or to insert the entire thermal paste applicator. This hollow tube constitutes a type of attachment structure 3. For example, the cross-sectional areas of the inner cavity can be the same, or the area can decrease inward to form an anti-detachment fastening at the inner end of the cavity after insertion. The cross-sectional structure of section B-B' shows another type of handle 22. A handle, the upper part of which is detachably or fixedly connected to a short tube parallel to each other in the same direction, the short tube being used to insert into the body (e.g., the lower section) of the thermal paste applicator or a pluggable sealing plug. The handle may be, for example, a hollow tube, solid, hollow or porous in the inner cavity. The handle may also be, for example, a square, rectangular, elliptical, plate or other shape in cross-section other than a circle. The handle may also be, for example, a variable diameter or equal diameter, or have a through hole or a hollowed-out outer shell.

[0063] Furthermore, it should be noted that, in another embodiment, the thermal paste spreading tool 2 may only include the working part 21 and the connecting part 23, without necessarily including the handheld part 22, which is advantageous in the following embodiments (e.g.Figure 2-2 This will be further described in the following section. In another embodiment, the connecting part 23 and the handle part 22 of the thermal paste spreading tool 2 are integrally formed.

[0064] Optionally, the attachment method of the attachment structure includes a detachable connection or a fixed connection. In this disclosure, a fixed connection is in contrast to a detachable connection; a fixed connection is a non-detachable connection. Furthermore, both detachable and non-detachable connections can be movable or non-movable connections. For examples of thermal paste spreading tools with syringe-type applicators attached using either detachable or fixed connection methods, their corresponding embodiments and integrated effects can be found in the respective references. Figure 2-1 , Figure 2-2 .

[0065] like Figure 2-1 The diagram illustrates an integrated thermal paste spreading tool with detachable connections. Sub-figures (a) and (b) show the tool, which includes a syringe-type applicator 1 and a thermal paste spreading tool 2. The syringe-type applicator 1 constitutes the syringe applicator, and the handle of the thermal paste spreading tool 2 forms a handle. The handle forms a hollow tube with an upper port, and the hollow tube forms a pluggable attachment structure. The syringe-type applicator can be inserted into the hollow tube through the upper port, achieving a pluggable attachment method.

[0066] Furthermore, the syringe-type applicator 1 and the hollow tube of the thermal paste spreading tool 2 can be fitted together by a plug-in connection. For example, after the syringe body is inserted into the hollow tube, the hollow tube can generate a certain circumferential pressing pressure on the syringe body, or generate friction between the contact surfaces of the hollow tube and the syringe body. This ensures that the syringe body does not easily detach from the handle.

[0067] It should be explained that, for detachable connections, if the attachment needs to be removed after the attachment is completed, the attachment structure between the syringe injector and the thermal paste spreading tool can be removed by means of damage, or preferably by means of elastic deformation without damage.

[0068] like Figure 2-2 This diagram illustrates an integrated thermal paste spreading tool with a fixed connection. Sub-figures (a) and (b) show a syringe-type applicator 1 and a thermal paste spreading tool 2. The syringe-type applicator 1 constitutes the syringe applicator. It is evident that the top of the pluggable sealing plug is fixedly connected to the top of the connecting portion 23 included in the thermal paste spreading tool 2. This is advantageous because the thermal paste spreading tool 2 can consist only of the working portion 21 and the connecting portion 23; the barrel 11 of the syringe-type applicator 1 can be considered and used as the handle of the thermal paste spreading tool 2, thus eliminating the need for a separate handle (e.g., a handle).

[0069] Anything requiring explanation or clarification, such as Figure 2-2 The top of the pluggable sealing plug 12 can also be connected to the top of the connecting portion 23 included in the thermal paste spreading tool 2 in a detachable manner, replacing the fixed connection. For example, the top of the pluggable sealing plug 12 can be connected to the top of the connecting portion 23 in a detachable manner, such as a plug-in connection or a threaded connection. The resulting detachable assembly has high structural robustness.

[0070] The above Figure 2-1 and Figure 2-2 The benefits of this embodiment include achieving structural integration and functional synergy between the thermal paste spreading tool and the thermal paste applicator, as well as facilitating space-saving storage, transportation, and shipping, and user access and storage. It enriches the product line of thermal paste, its applicators, and application tools, promoting the differentiated value and sales of thermal paste, its applicators, and / or thermal paste spreading tools, and giving the thermal paste spreading tools uniqueness and brand recognition.

[0071] For example, to obtain Figure 2-1 The hollow tube handle also saves materials and easily meets the necessary handle thickness for better hand ergonomics. For example, obtaining... Figure 2-2 The thermal paste spreading tool uses the syringe-type applicator as a handle (eliminating the need for an additional dedicated handle), thus saving materials and being more environmentally friendly.

[0072] It needs to be explained and clarified that the thermal paste spreading tool in this disclosure has the function of carrying a thermal paste applicator by means of a supporting structure. It may carry (i.e., be integrated with) a thermal paste applicator, or it may not carry (i.e., not be connected to) a thermal paste applicator.

[0073] Therefore, one product form of the thermal paste spreading tool in this disclosure is: a thermal paste spreading tool with an attached (i.e., integrated) thermal paste dispenser. This achieves a structural relationship and functional synergy where both are used for thermal paste, but the former is used for spreading and the latter for container. Furthermore, the attachment of the thermal paste dispenser gives the thermal paste spreading tool its unique function, thus achieving its distinctiveness and identifiability. It also allows for convenient access to the thermal paste dispenser and convenient storage, reducing the possibility of loss. Finally, it facilitates convenient shipping of both.

[0074] Another form of the thermal paste spreading tool disclosed herein is a thermal paste spreading tool without a thermal paste applicator (i.e., without a thermal paste applicator attached). This allows users to purchase, for example, a thermal paste spreading tool without a thermal paste applicator separately. This means that if the user has, for example, an existing syringe applicator, they can attach the syringe applicator to the thermal paste spreading tool, thus achieving a detachable connection between the two. This reduces the possibility of losing the syringe applicator, facilitates convenient storage, and improves the ease of use for subsequent thermal paste application.

[0075] It should also be explained and clarified that the attachment method of the attachment structure includes detachable connection or fixed connection; or, the attachment method of the attachment structure is detachable connection, and the detachable connection includes snap connection, threaded connection, key connection, pin connection, plug connection, insertion and reception, quick coupling, flange connection, clamping connection, cable tie connection, adhesive connection, negative pressure adsorption connection, magnetic connection or tenon and mortise connection. This means that, understandably, in order to enable the attachment structure to attach a thermal paste dispenser, in some embodiments, the corresponding attachment structure requires at least one set of mating parts for connection, which can be defined as a female mating part and a female mating part. The female mating part is attached to the handle (or connecting part) and the female mating part is attached to the thermal paste dispenser, or the female mating part is attached to the thermal paste dispenser and the female mating part is attached to the handle (or connecting part). For example, a threaded connection requires a bolt and a screw as the female mating part and the female mating part, respectively. For example, the female mating part can be a barrel, a pluggable sealing plug, or a piston handle that is fixedly or detachably connected to the thermal paste dispenser. Thus, the female mating part can be a syringe attached to an existing thermal paste container type to form a syringe-type dispenser.

[0076] In other embodiments, the corresponding mounting structure requires a mating component for connection, which is attached to the handle (or connector), for example... Figure 2-1 The hollow tube 211 of the thermal paste spreading tool 2 can be considered as a matching part for connection. However, it is also easy to understand that the barrel 11 of the syringe-type dispenser 1, as an insert, can be considered as the aforementioned sub-matching part, and the hollow tube 211 of the thermal paste spreading tool 2 can be considered as the aforementioned mother matching part. Therefore, a syringe of the existing thermal paste container type can be used to construct another syringe-type dispenser. It can be seen that these different implementations actually have both differences and uniformities.

[0077] For example, snap-fit ​​connections securely link two or more components together by locking them into specific areas. They rely on the properties of elastic materials, fitting snugly into slots, holes, or grooves in the connecting objects to firmly secure the connectors without the need for additional tools or equipment. The elastic material can fit into slots, holes, or grooves to form a mounting structure, where the elastic material can be considered a sub-matching component, and the slot, hole, or groove can be considered a female-matching component; or vice versa. For instance, if the elastic material is used as a sub-matching component, it can be either fixedly or detachably connected to a thermal paste applicator. Snap-fit ​​connections are generally considered an efficient and convenient connection method. They offer unique advantages, especially in environments with low installation precision requirements or limited operating space.

[0078] To make these embodiments clearer and easier to understand, the preferred mounting structure will be described in detail below with reference to the accompanying drawings.

[0079] Please refer to Figure 3-1 Sub-figure (a1) shows a schematic diagram of the insertion connection of a thermal paste spreading tool, showing a syringe-type applicator 1, a thermal paste spreading tool 2, and an inner liner 31. The inner liner 31 is, for example, a rib on the inner wall of the hollow tube of the handle. The rib forms radial pressing and / or axial friction when the thermal paste applicator is inserted, thereby preventing the cylinder of the thermal paste applicator from easily coming out of the hollow tube of the handle. Sub-figure (a2) shows a schematic diagram of the C-C' cross-section. Furthermore, sub-figure (b1) shows a structural schematic diagram of a snap-fit ​​connection for a thermal paste spreading tool, showing a syringe-type applicator 1 and a thermal paste spreading tool 2; and sub-figure (b2) shows a structural schematic diagram of the D-D' cross-section, showing that the syringe-type applicator 1 is seated in the snap-fit ​​groove of the thermal paste spreading tool 2. The syringe-type applicator 1 can be inserted into the snap-fit ​​groove through a plug-in connection from the upper port of the handle, or it can be seated (e.g., inserted) from the handle and the side of the snap-fit ​​groove to accommodate the syringe-type applicator 1. It can be considered that all or part of the syringe-type applicator 1 can be attached to the inner circumference of the handle of the thermal paste spreading tool 2.

[0080] In some similar embodiments, the handle is configured such that one side of the handle can be seated into the syringe applicator, the handle being used to allow the barrel, or all or part of the syringe applicator, to form the insertion receiving position. For example, the side of the handle has a slot for receiving a thermal paste applicator (e.g., a syringe applicator); this slot may optionally extend and pass through to the upper end of the handle; or the slot may extend but not pass through to the upper end of the handle, in which case the upper end of the handle can be easily coupled, for example, to a pre-spreading aid in a fixed or detachable connection.

[0081] In this embodiment of the present disclosure, the upper port of the hollow tube of the thermal paste spreading tool is preferably coupled with a constraint structure to prevent the tube from easily falling off when inserted. For example, the constraint structure may be an expandable elastic ring plug; or a rib with an elastically deformable radially extending section on the inner wall of the hollow tube; or an elastic liner on the tube of a syringe-type applicator, etc.

[0082] In this embodiment of the present disclosure, the slot in the handle of the thermal paste spreading tool is preferably coupled with a constraint structure to prevent the tube from easily falling off when inserted. For example, the constraint structure may be a handle housing forming the slot, which, for example, can generate an inward elastic force after being stretched; or the slot may have a snap-fit ​​structure for the handle; or the slot may have an adhesive layer; or the slot may have a snap-fit ​​structure, etc.

[0083] Please refer to Figure 3-2 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 applicator 1, a thermal paste spreading tool 2, and an attachment structure 3. Sub-figure (a2) shows a schematic diagram of its cross-sectional structure along section E-E'. Sub-figure (b1) shows a schematic diagram of the snap-fit ​​connection structure of a thermal paste spreading tool, showing that it includes a syringe-type applicator 1, a thermal paste spreading tool 2, and an attachment structure 3. Sub-figure (b2) shows a schematic diagram of its cross-sectional structure along section F-F', showing that the body of the syringe-type applicator 1 is seated in the snap-fit ​​groove of the thermal paste spreading tool 2. It can be considered that the syringe-type applicator 1 is attached to the periphery (e.g., the upper part) of the handle of the thermal paste spreading tool 2.

[0084] It's understandable. Figure 3-2 In sub-figures (a2) and (b2), the handle of the thermal paste spreading tool 2 shown is a hollow tube. The hollow tube can be replaced by, for example, a solid handle or a handle with a porous inner cavity. Its cross-section can be square, rectangular, elliptical, plate-shaped or other shapes other than circular.

[0085] Please refer to Figure 3-3Sub-figure (a) shows a schematic diagram of the plug-in connection structure of a thermal paste spreading tool, including a syringe-type applicator 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 applicator 1 is connected to the hole in the attachment structure 3 in a plug-in connection attachment form. Sub-figure (b) similarly shows a schematic diagram of the plug-in connection structure of a thermal paste spreading tool, including a syringe-type applicator 1, a thermal paste spreading tool 2, and an attachment structure 3. It can be seen that the handle and the connecting part of the thermal paste spreading tool can be set at a certain angle to obtain different user experiences and effects.

[0086] Additionally, exemplarily, the handle of the thermal paste spreading tool may have a straight axis, or the axis may be partially broken or curved. Furthermore, exemplarily, the handle may be retractable. Optionally, the syringe-type applicator may have a circular or elliptical cross-section, or it may be of constant or variable diameter. Optionally, the outer surface of the thermal paste applicator (e.g., top, bottom, or body) may be fixedly connected to the connecting portion. Optionally, the roller body of the thermal paste spreading tool may be replaced with a ball body. A hollow tube should be considered as one of the aforementioned tube types.

[0087] In summary, the embodiments disclosed herein achieve structural association and functional synergy between the thermal paste spreading tool and the thermal paste applicator, giving the thermal paste spreading tool uniqueness and identifiability. It also promotes the differentiated value and sales of both the thermal paste spreading tool and the thermal paste itself, enhances the user experience, facilitates storage, transportation, and delivery, and allows users to easily access and store the product using an integrated, mounted, and carried device.

[0088] In a second aspect, this disclosure also provides an embodiment of a thermal paste applicator having the aforementioned attachment structure; the attachment structure allows the thermal paste applicator to be fixedly or detachably connected to a thermal paste spreading tool. Preferably, the connection portion corresponding to the attachment structure is the handle or connecting portion of the thermal paste spreading tool. Preferably, the thermal paste applicator is a syringe-type applicator. It should be noted and understood that, optionally, the thermal paste spreading tool may refer to the thermal paste spreading tool in the first aspect, or it may be a thermal paste spreading tool other than that in the first aspect. The thermal paste spreading tool in the second aspect and its embodiments may be the same as or different from the thermal paste spreading tool in the first aspect and its embodiments, that is, it is not necessarily considered and understood as a requirement.

[0089] In another aspect, this disclosure provides a thermal paste applicator having a second mounting structure; the second mounting structure is configured to engage with a first mounting structure on a thermal paste spreading tool, such that the thermal paste applicator is fixedly or detachably connected to the thermal paste spreading tool. Preferably, the thermal paste applicator is a syringe-type applicator. Optionally, the thermal paste spreading tool may refer to the foregoing description.

[0090] This disclosure also provides a pre-spreading auxiliary tool for attaching a thermal paste applicator, the pre-spreading auxiliary tool comprising: a third working part having a third working surface on its outer surface, the third working surface being constructed as a raised third curved surface, the two principal curvatures of the third curved surface being positive; a third handheld part for manually controlling the pre-spreading auxiliary tool to cause the third working part to press and / or roll the thermal paste; and a third connecting part for connecting the third working part and the third handheld part in a fixed or movable manner, wherein the third handheld part or the third connecting part is provided with a third attachment structure for attaching the pre-filled thermal paste applicator, or...

[0091] A third working part having a third working surface on its outer surface, the third working surface being constructed as a raised third curved surface, the two principal curvatures of the third curved surface being positive, and a third connector for being connected to the third working part in the form of a fixed connection or a movable connection, and the third connector being provided with a third attachment structure for attaching the thermal paste applicator pre-loaded with thermal paste.

[0092] Preferably, the pre-spreading auxiliary tool includes: the third curved surface, which is constructed as a third sphere.

[0093] Furthermore, the pre-spreading auxiliary tool includes: the third spherical surface, which is contained within a third sphere.

[0094] It should be explained that the third working part should be understood as the working part of the pre-spreading auxiliary tool, the third handheld part should be understood as the handheld part of the pre-spreading auxiliary tool, and the third connecting part should be understood as the connecting part of the pre-spreading auxiliary tool. This description is only for the purpose of more clearly distinguishing the working part, handheld part, and connecting part included in the aforementioned thermal paste spreading tool that can be used to attach thermal paste applicators.

[0095] Please see Figure 4-1The diagram illustrates an integrated thermal paste spreading tool that also includes a pre-spreading aid. It shows a thermal paste spreading tool 2 and a pre-spreading aid 4. The handle of the thermal paste spreading tool 2 is a hollow tube with an upper port for inserting a syringe-type applicator. The pre-spreading aid 4 includes a working part 41 and a connecting part 42. The working part 41 is specifically a sphere, and the upper end of the connecting part 42 is fixedly or detachably connected to the upper port of the handle of the thermal paste spreading tool 2. Therefore, the thermal paste spreading tool, including the pre-spreading aid, forms a multifunctional composite tool with a roller body and a sphere.

[0096] In particular, pre-spreading aids, by constructing a curved surface with defined curvature as the working surface, exhibit stronger non-stick properties compared to spreading tools of the same material, such as cylindrical rollers or scrapers, when applied to the paste by pressing and / or rolling. The defined curved surface structure of this tool is primarily used for the initial spreading of the paste. After rolling, the paste becomes locally flat and dense, forming a micro-pit array where the thermal paste is locally embedded into the heat source, such as the surface of a chip, thus achieving initial cavitation elimination. Then, using a cylindrical roller, the final spreading can be easily completed, and the thermal paste is no longer easily adhered to in lumps or sheets by the roller body. Therefore, pre-spreading aids are geometrically constructed with relatively non-stick properties suitable for spreading thermal paste.

[0097] This non-stick effect does not originate from surface coatings, plating, or modification of the material, but merely from a change in geometry, thus saving on the processing costs that would otherwise be incurred on the roller surface. The effect will be even more pronounced after coupling the non-stick coating, making it easier to achieve more efficient and high-quality thermal paste application using the roller body. Furthermore, in terms of production, existing industrial manufacturing methods can efficiently, efficiently, and cost-effectively produce the curved surfaces or structures required by this disclosure.

[0098] Please see Figure 4-2 The diagram illustrates the integrated effect of a pre-spreading auxiliary tool detachably connected to a thermal paste spreading tool, with a syringe-type applicator attached via an insertion and accommodating method. The diagram shows a thermal paste spreading tool 2 and a pre-spreading auxiliary tool 4. The handle of the thermal paste spreading tool 2 is a hollow tube with an upper port into which the syringe-type applicator can be inserted. The pre-spreading auxiliary tool 4 includes a working part 41 and a connecting part 42. The working part 41 is specifically a sphere, and the upper end of the connecting part 42 is connected to the upper port of the handle of the thermal paste spreading tool 2 via an insertion connection.

[0099] It can be seen that, as Figure 4-2The embodiment comprises a multifunctional composite tool with a roller body and a sphere, and a syringe-type applicator is attached to the hollow tube via an insertion and receiving method. This achieves structural integration and functional synergy between the thermal paste spreading tool and the thermal paste applicator, giving the thermal paste spreading tool a unique and identifiable identity. It also promotes the differentiated value and sales of both the thermal paste spreading tool and the thermal paste, enhances the user experience, facilitates storage, transportation, and shipping, and allows users to easily access and store the product using the integrated applicator (or mounted on it).

[0100] In a similar embodiment, the handle of the thermal paste spreading tool 2 has the aforementioned slot, and a syringe-type applicator can be seated (e.g., inserted into) in the slot from the side of the handle. This slot can be created based on a hollow tube, which may or may not have an upper port; alternatively, it can be added to a non-hollow tube, and the slot can extend through the upper end of the handle (or extend but not through the upper end of the handle).

[0101] In addition, it should be clarified that for pre-spreading auxiliary tools with hollow tubes, in addition to inserting or stuffing containers for carrying thermal paste applicators, the hollow tubes can also replace (or simultaneously carry) small devices required for DIY manual thermal paste replacement and simultaneous dust removal, such as scrapers, screwdrivers, pry bars, cleaning wipes, finger cots, thermal pads, etc.

[0102] It should be explained and clarified that the first working piece and the second working piece, in different (or identical) embodiments, may have the same or different specific structures, and should all be understood as working modules (or working parts) of the pre-laying auxiliary tool. Similarly, the first connecting piece and the second connecting piece, in different (or identical) embodiments, may have the same or different specific structures, and should all be understood as connecting modules (or connecting parts) of the pre-laying auxiliary tool. The terms "first" and "second" here are only for convenience in subsequent reference and description. The pre-laying auxiliary tool in this disclosure may include a working piece, a connecting piece, and a handheld piece, or it may include a working piece and a connecting piece.
