[0005]

[0001] The present invention relates to a kit for forming a heat pipe with respect to a receiving structure, a cooling element including the kit, a heat transfer system, and a method for forming a heat pipe with respect to a receiving structure.

Background Art

[0002] The cooling of electrical components such as microprocessors, LEDs, and IGBT modules has conventionally been based on physically and thermally connecting and attaching a cooling element to the component. A typical such cooling element includes a heat transfer device for transferring heat between two solid interfaces, such as a heat pipe.

[0003] The heat pipe of the cooling element is typically joined to the base by mechanical press-fitting, adhesion, soldering, brazing, or welding, or screw connection. It is difficult to join by soldering or welding. This is because it is necessary to control the temperature and flow of the connecting alloy to avoid damage to the heat pipe and to continuously and tightly bond between the joint portions. Screw connection requires complicated machining of the heat pipe and the base. If the joint is poor, the operation of the cooling element is hindered and repair is difficult.

[0004] Therefore, there is still a need to further improve the joining of the heat pipe to the base or at least provide a useful alternative means without unduly increasing the complexity of the heat transfer system.

DETAILED DESCRIPTION OF THE INVENTION

[0012] In this context, a "cooling element" refers to a device for cooling an electrical component or an optical component.

[0013] In this context, a "profile material" refers to a heat transfer device that utilizes a phase transition to transfer heat between two solid interfaces. The profile material may be a heat pipe. A heat pipe is a heat pipe that returns a liquid to an evaporator by gravity or other acceleration forces. The profile material may constitute a condensation part of the heat pipe.

[0014] In this context, a "heat pipe structure" refers to a structure including a profile material and a sleeve. A heat pipe structure is a structure capable of moving a fluid and thus further heat.

[0015] In this context, an "evaporator" refers to a device used to turn a liquid into a vapor. The evaporator may be a surface evaporator.

[0016] In this context, "enclosed" means that an element or structure is incorporated into another element or structure.

[0017] In this context, "incorporated" means that an element or structure is an essential part of another element or structure and those elements or features are inseparable. Further, "incorporated" means that an element or structure is formed from the material of the main body part.

[0018] Connecting profile materials, particularly heat pipes, to a support structure can be challenging. This is because controlling the temperature and flow of the connecting alloy during machining of each component, or during soldering or welding, can be complex. Furthermore, the resulting joint may not be sufficiently tight, potentially preventing the assembled product from performing at its best. At least some of these problems are addressed by at least some of the embodiments described above.

[0019] The kit for forming a heat pipe on the receiving structure is: -Profile material 110 including mounting end 111, - A sleeve 130 having a front edge 131 and a rear edge 132, wherein the inner diameter is larger at the front edge 131 than at the rear edge 132, It can include, The sleeve 130 is positioned around the mounting end 111 of the profile material 110 and is configured to apply a radial force to the mounting end 111.

[0020] Therefore, the sleeve 130 may gradually taper from the trailing edge 132 to the leading edge 131. The kit allows for a secure, tight, and inexpensive bond between the profile material and the receiving structure. The kit avoids soldering, which requires temperature control, and complex screw connections.

[0021] The mounting end 111 is, - Enlarged section 113 and, - The narrow part 115 connected to the enlarged part 113, -Any transitional section 114 between the enlarged section 113 and the narrowed section 115, It can include, The maximum nominal outer diameter of the enlarged portion 113 is larger than the nominal outer diameter of the narrowed portion 115. The mounting end allows the profile material to be securely attached to the receiving structure. The enlarged portion allows for a larger joint to be formed between the profile material and the receiving structure. This improves the function of the cooling element when the kit is used as a cooling element.

[0022] The enlarged portion 113 can be formed on the profile material 110 during its fabrication. Alternatively, the enlarged portion 113 can be formed after the profile material 110 has been fabricated.

[0023] Figure 1 shows the kit. The kit includes a profile material 110 and a sleeve 130. The profile material 110 includes a mounting end 111. The mounting end 111 includes an enlarged portion 113, a narrowed portion 115, and a transition portion 114 between the enlarged portion 113 and the narrowed portion 115. The sleeve 130 has a front edge 131 and a rear edge 132. The inner diameter of the sleeve 130 is larger at the front edge 131 than at the rear edge 132.

[0024] The nominal outer diameter of the transition section 114 may be larger than the nominal outer diameter of the narrowed section 115 and smaller than the nominal outer diameter of the widened section. The nominal outer diameter of the transition section 114 may decrease towards the narrowed section 115. In other words, the transition section may taper towards the end.

[0025] Alternatively, the mounting end 111 may include a shoulder portion (not shown) between the enlarged portion 113 and the narrowed portion 115. In this case, the mounting end 111 cannot include the transition portion described above, and the narrowed portion 115 may be directly connected to the enlarged portion.

[0026] The nominal outer diameter of the enlarged portion 113 may be 1 to 50%, preferably 5 to 20%, larger than the nominal outer diameter of the narrowed portion 115. This allows for a larger joint to be formed between the profile material and the receiving structure. This improves the function of the cooling element 100 when the kit is used in the cooling element 100.

[0027] The sleeve 130 may be configured to move along the narrow portion 115 without causing plastic deformation of the narrow portion 115. Therefore, the sleeve is easy to move along the narrow portion and does not damage the narrow portion when moving along it.

[0028] The sleeve 130 may be configured to plastically deform the enlarged portion 113 when moved along the enlarged portion 113. Therefore, the sleeve can be pressed against the periphery of the mounting end, allowing the mounting end to be tightly and securely connected to the receiving structure.

[0029] The nominal inner diameter of the trailing edge 132 of the sleeve 130 may be smaller than the maximum nominal outer diameter of the enlarged portion 113, as shown in Figure 1. Therefore, when the sleeve is placed around the enlarged portion 113, it is configured to apply a radial force to the enlarged portion 113.

[0030] The nominal inner diameter of the leading edge 131 of the sleeve 130 may be larger than the nominal outer diameter of the enlarged portion 113, as shown in Figure 1. This makes it easier for the sleeve to slide around the enlarged portion.

[0031] The nominal inner diameter of the trailing edge 132 of the sleeve 130 may be larger than the nominal outer diameter of the narrowed portion 115, as shown in Figure 1. Therefore, the sleeve can be easily moved along the narrowed portion without damaging it during movement.

[0032] The sleeve 130 may further include an oblique or rounded portion behind the trailing edge 132. In this case, the sleeve can be easily positioned around the profile material. This is because the sleeve can be positioned around the profile material regardless of whether the leading edge 131 or the trailing edge 132 is in front.

[0033] Figure 2 shows a kit including a sleeve 130 having an angled section. The sleeve includes a leading edge 131, a trailing edge 132, and an angled section formed behind the trailing edge. The sleeve 130 has its smallest nominal inner diameter at the trailing edge. The nominal inner diameter of the sleeve is substantially the same at the leading edge 131 and the angled section. The kit further includes a profile material.

[0034] The profile material 110 is preferably made of a thermally conductive material such as aluminum or an aluminum alloy. The cross-section of the profile material 110 may be circular or any other suitable shape.

[0035] The profile material 110 can be used as a heat pipe. The profile material 110 may have an enclosed space, and a heat transfer fluid is placed in this space and allowed to act. The heat transfer fluid is preferably a saturated vapor that contains little or no impurities.

[0036] According to one embodiment, the cooling element 100 is - The kits mentioned above, - A base portion 120 including a collar portion 121 that defines the opening 122, Includes, The mounting end 111 of the profile material 110 is positioned around the collar portion 121, and the sleeve 130 is positioned around the mounting end 111 of the profile material 110, applying a radial force to the mounting end 111.

[0037] The aforementioned kit allows for a secure, tight, and inexpensive bond between the profile material and the base of the cooling element.

[0038] The phrase "the profile material is positioned around the colored portion" means that the colored portion may be at least partially inside the profile material. Therefore, the profile material may at least partially enclose the colored portion. In this case, the inner surface of the profile material and the outer surface of the colored portion may be in contact.

[0039] The phrase "the sleeve is positioned around the mounting end" means that the mounting end may be at least partially inside the sleeve. Therefore, the sleeve may at least partially enclose the mounting end. In this case, the inner surface of the sleeve and the outer surface of the mounting end may be in contact.

[0040] According to one embodiment, the base 120 encloses an evaporator 140 that is fluidly connected to the profile material 110 through an opening 122. That is, the evaporator 140 is an integral part of the base 120. This means that the evaporator 140 cannot be separated from the base 120. The evaporator 140 is formed as a void in the base material of the base 120. To integrate the evaporator 140 into the base 120, the base 120 is fabricated and then a channel is formed in the base 120 by machining. Alternatively, the evaporator 140 can be fabricated during the extrusion or pour molding of the base 120.

[0041] The evaporator 140 may have a width in a first dimension X and a height in a second dimension Y. According to at least some embodiments, the width is considerably greater than the height, so that the evaporator is generally flat. The purpose of the flat shape is to collect heat from a wider area and transfer it to the profile material and disperse the heat in the second dimension Y. Such an effect is particularly useful when diffusing and dispersing heat from a high-temperature location or a small area heat source over a large surface area or a large space. The evaporator may have an enclosed space in which a heat transfer fluid is included and acts.

[0042] Figure 3 shows the cooling element 100. The cooling element includes a kit comprising a profile material 110 and a sleeve 130. The profile material 110 includes a mounting end 111. The mounting end 111 includes an enlarged portion 113, a narrowed portion 115, and a transition portion 114 between the enlarged portion 113 and the narrowed portion 115. The sleeve 130 has a front edge 131 and a rear edge 132. The inner diameter of the sleeve 130 is greater at the front edge 131 than at the rear edge 132. The cooling element 100 further includes a base 120. The base 120 encloses the evaporator 140.

[0043] According to one embodiment, the base portion 120 includes a space 123 around the collar portion 121, and the mounting end 111 and the sleeve 130 are arranged in the space 123. The space allows the mounting end 111 and the sleeve 130 to be arranged around the collar portion 121.

[0044] Space 123 can be formed in the base 120 during its fabrication. Therefore, space 123 can be formed during the casting of the base 120. Alternatively, space 123 can be formed in the base 120 after its fabrication. Space 123 can be formed, for example, by machining.

[0045] As shown in Figure 3, space 123 may extend from the collar portion 121 in the first dimension X along the width direction of the base portion 120. This makes it possible to arrange mounting ends and sleeves of various wall thicknesses around the collar portion.

[0046] Alternatively, the space 123 can be incorporated into the base 120, and the space 123 may have at least one side open to receive the mounting end 111. In this case, the space 123 is enclosed by the collar portion 121 and the base material of the base 120, as shown in Figures 4 to 7. Thus, the mounting end 111 and the sleeve 130 can be closely positioned at the base between the collar portion 121 and the base material of the base 120.

[0047] Figure 4 shows the base 120 including space 123. The base 120 further includes a collar portion. Space 123 is enclosed by the collar portion 121 and the base material of the base 120. The mounting end 111 of the profile material 110 and the sleeve 130 are configured to be positioned in space 123.

[0048] Figure 5 shows the cooling element 100 including the base 120 of Figure 4. The mounting end 111 and the sleeve 130 are located in the space 123. Therefore, the base material of the collar portion 121 and the base 120 enclose the mounting end 111 and the sleeve 130.

[0049] Figure 6 shows the base 120 including space 123. Space 123 is enclosed by the collar portion 121 and the base material of the base 120. The mounting end 111 of the profile material 110 and the sleeve 130 are configured to be positioned in space 123.

[0050] Figure 7 shows the cooling element 100 including the base 120 of Figure 6. The mounting end 111 and the sleeve 130 are located in the space 123. Therefore, the base material of the collar portion 121 and the base 120 enclose the mounting end 111 and the sleeve 130.

[0051] According to one embodiment, the yield strength between the collar portion 121 and the sleeve 130 is greater than the yield strength of the enlarged portion 113. Therefore, the collar portion can withstand the radial force applied by the sleeve without deformation, but the sleeve may cause plastic deformation of the enlarged portion as it moves along it. This makes it possible to create a tighter connection between the sleeve and the enlarged portion. In addition, even if the sleeve is placed around the enlarged portion and the collar portion, the shape of the collar portion does not change. Therefore, the operation of the cooling element 100 is not affected.

[0052] According to one embodiment, the base portion 120 is configured to extend in a first dimension X, and the profile material 110 is configured to extend in a second dimension Y that is angled with respect to the first dimension X. By adjusting the angle, heat can be directed in a desired direction.

[0053] According to one embodiment, the angle between the first dimension X and the second dimension Y is 5 to 45 degrees, preferably 5 to 25 degrees. For example, the angle is 5 degrees, 10 degrees, 15 degrees, 20 degrees, or 25 degrees.

[0054] Figure 8 shows a profile material 110 and a base 120 for forming a cooling element that includes an angled profile material 110. The profile material 110 includes a sleeve 130 around its periphery. The base 120 includes a collar portion 121. The collar portion 121 extends in a second dimension Y that is angled with respect to a first dimension X. Space 123 extends from the collar portion 121 along the width direction of the base 120 in the first dimension X. The profile material 110 and the sleeve 130 are arranged around the collar portion 121 to form a cooling element that includes the angled profile material 110.

[0055] Figure 9 shows a profile material 110 and a base 120 including a space 123 for forming a cooling element that includes an angled profile material 110. The profile material 110 includes a sleeve 130 around its periphery, and the base 120 includes a collar portion 121. The collar portion 121 extends in a second dimension Y that is angled with respect to a first dimension X. The space 123 is enclosed by the collar portion 121 and the base material of the base 120. The profile material 110 and the sleeve 130 are arranged around the collar portion 121 to form a cooling element that includes the angled profile material 110.

[0056] Figure 10 shows a profile material 110 and a base 120 including a space 123 for forming a cooling element that includes an angled profile material 110. The profile material 110 includes a sleeve 130 around its periphery, and the base 120 includes a collar portion 121. The collar portion 121 extends in a second dimension Y that is angled with respect to a first dimension X. The space 123 is enclosed by the collar portion 121 and the base material of the base 120. The profile material 110 and the sleeve 130 are arranged around the collar portion 121 to form a cooling element that includes the angled profile material 110.

[0057] The profile material 110 may be curved. This allows for more effective use of the space when the space is limited in a first direction X. In this case, the space in a second direction Y can be used to provide a profile material long enough to effectively transfer heat. In addition, the sleeve reinforces the connection to the base of the curved profile material.

[0058] The bending angle of the profile material 110 may be 5 to 45 degrees, preferably 5 to 25 degrees.

[0059] Figure 11 shows a cooling element 100 including a curved profile material 110. The cooling element 100 includes a base 120 that encloses the evaporator 140. The base further includes a space. The curved profile material 110 includes a mounting end 111 and a sleeve 130 around the mounting end 111. The mounting end 111 and the sleeve are located in a space 123. The evaporator is in fluid contact with the curved profile material 110 through an opening 122.

[0060] According to one embodiment, the heat transfer system includes a cooling element 100 as described above and a heat source connected to the base 120. The heat source may be, for example, an electrical component or an optical component.

[0061] According to one embodiment, a method for forming a heat pipe with respect to a receiving structure is: - The process of preparing the receiving structure, - A step of preparing a profile material 110 including the mounting end 111, - A step of positioning the mounting end 111 of the profile material 110 so as to be in contact with the receiving structure, - A sleeve 130 having a front edge 131 and a rear edge 132, wherein the inner diameter is larger at the front edge 131 than at the rear edge 132, - A step of placing the sleeve 130 around the profile material 110, - A step of moving the sleeve 130 along the profile material 110 to surround the mounting end 111, thereby applying radial force to the mounting end 111 and pressurizing the mounting end 111 against the receiving structure, Includes.

[0062] The above method allows for a secure, tight, and inexpensive bond between the profile material and the receiving structure. The kit eliminates the need for soldering, which requires temperature control, and complex screw connections.

[0063] The receiving structure may also be a base portion 120.

[0064] The aforementioned installation may be carried out using a kit as described above.

[0065] As described above, the mounting end 111 may include an enlarged portion 113, a narrowed portion 115 connected to the enlarged portion 113, and an optional transition portion 114 between the enlarged portion 113 and the narrowed portion 115. The maximum nominal outer diameter of the enlarged portion 113 is greater than the nominal outer diameter of the narrowed portion 115. Furthermore, the method may include the step of moving the sleeve 130 around the narrowed portion 115 and then moving the sleeve 130 around the mounting end 111. Thus, the sleeve may be slid over the opposite second end to surround the profile material, and then moved around the narrowed portion to surround the mounting end.

[0066] According to one embodiment, the method further includes the step of moving the sleeve 130 along the narrow portion 115 without causing plastic deformation of the narrow portion 115. The sleeve can be moved along the narrow portion without damaging it.

[0067] According to one embodiment, the method further includes the step of plastically deforming the mounting end 111 when moving the sleeve 130 along the enlarged portion 113. Thus, the mounting end can be tightly connected to the receiving structure. The resulting joint is a tight fit and leak-free. As a result, when the profile material is attached to the base of the cooling element 100 using the method, the performance of the cooling element 100 is improved.

[0068] According to one embodiment, the receiving structure is a male receiving structure.
