[0037] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0038] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0039] See also Figure 1-8 As shown, the radiator is also called a radiator, which mainly includes a radiator body 1 and a fan module 2; the radiator body 1 includes two oppositely arranged waterway plates 11, and the waterway plates 11 are provided with water channels for circulating hot water or steam and other hot fluids. When the hot fluid flows through the water channel, the heat can be transferred to the waterway plates 11, and then dissipated through the heat dissipation fins between the two waterway plates 11 to achieve heating.

[0040] The fan module 2 mainly accelerates the air circulation efficiency between the two water channel plates 11 through the operation of the fan 22 to improve the heat dissipation efficiency.

[0041] This embodiment provides a fan module 2, such as Figure 3 As shown, it mainly includes a bracket 21, one or more fans 22 mounted on the bracket 21, and two connecting members 3. This embodiment is described below by taking the example of multiple fans 22 mounted on the bracket 21. The bracket 21 is a hollow rectangular mesh structure.

[0042] In addition, in this embodiment, for the convenience of explanation, Figure 4 As shown, the length direction of the bracket 21 is recorded as the first direction, the direction perpendicular to the first direction is recorded as the second direction, and the second direction can also be understood as the width direction of the bracket 21; the direction perpendicular to the first and second directions is recorded as the third direction, and the third direction can also be understood as the thickness direction of the bracket 21. In other words, the first direction, the second direction, and the third direction can be understood as the X, Y, and Z axes of the three-axis coordinate system.

[0043] In this embodiment, first convex edges 223 are formed on both sides of the fan 22 , and the first convex edges 223 extend along a first direction.

[0044] Combine Figure 4 and Figure 7 As shown, the bracket 21 includes two sliding grooves 212 extending along the first direction and used for the two first protrusions 223 to slide and fit respectively. In some embodiments, the structure of the sliding grooves 212 is:

[0045] The sides of the bracket 21 are rolled up to form a rolled edge 211 , and the sliding groove 212 is formed by surrounding the rolled edge 211 .

[0046] In this way, the fan 22 can be slid into the slide groove 212 from the end side of the bracket 21 along the first direction through the first flanges 223 on both sides. When the first flange 223 is inserted into the slide groove 212, the fan 22 remains positioned relative to the bracket 21 in the second direction and the third direction, that is, the fan 22 cannot move relative to the bracket 21 in the second direction and the third direction, so that the fan 22 can only move along the first direction.

[0047] The two connecting members 3 are respectively detachably plugged into the two ends of the bracket 21 to limit the fan 22 from sliding out from the end side of the bracket 21 along the first direction. In this way, under the restriction of the two connecting members 3, the fan 22 cannot slide out from the end side of the bracket 21 along the first direction, so that the entire fan 22 remains on the bracket 21.

[0048] In addition, in order to enable the fans 22 to be connected to form an integral module, in some embodiments, the fans 22 are sequentially spliced ​​along the first direction, for example:

[0049] like Figure 4 As shown, among the two adjacent fans 22, one is provided with a clamping head 221, and the other is provided with a slot 222 for the clamping head 221 to be inserted along the third direction; the clamping head 221 and the slot 222 are roughly T-shaped structures; when the clamping head 221 is inserted into the slot 222 along the third direction, the two adjacent fans 22 maintain relative positioning in the first direction and the second direction to achieve splicing of the two adjacent fans 22, that is, under the restriction of the clamping head 221 and the slot 222, the two adjacent fans 22 can only move relative to each other along the third direction; and when the fans 22 are installed on the bracket 21, under the restriction of the bracket 21, the two adjacent fans 22 are limited in the third direction and cannot move relative to each other along the third direction, so that each fan 22 forms a whole.

[0050] On the other hand, for a single fan 22 , a clamping head 221 is provided on one side of the fan 22 , and a clamping slot 222 is provided on a side opposite to the clamping head 221 , so that two fans 22 can be spliced ​​together.

[0051] In some embodiments, the fan module 2 also includes a circuit board 4 electrically connected to the fan 22, such as a PCB board; in order to facilitate the disassembly and assembly of the circuit board 4 from the bracket 21, the fan module 2 also includes a mounting component 5 for mounting the circuit board 4; the mounting component 5 is detachably arranged on the bracket 21.

[0052] As an optional implementation, Figure 5As shown, the mounting member 5 is provided with second flanges 521 on both sides that can be slidably inserted into the two slide grooves 212 along the first direction. The second flanges 521 extend along the first direction, and when the second flanges 521 are inserted into the slide grooves 212, the mounting member 5 remains positioned relative to the bracket 21 in the second and third directions. It will be understood that the engagement of the second flanges 521 with the slide grooves 212 is similar to the engagement of the first flanges 223 with the slide grooves 212, and both are inserted into the slide grooves 212 in a slidable manner.

[0053] In some embodiments, the specific structure of the second convex edge 521 is as follows: the mounting member 5 is in a U-shaped structure as a whole, and both ends of the mounting member 5 are folded outward to form the second convex edge 521 .

[0054] The circuit board 4 is detachably mounted on the mounting member 5. For example, the circuit board 4 is clamped on the mounting member 5. Specifically:

[0055] The mounting member 5 includes two side panels 52 arranged opposite each other along the second direction and a top panel 51 disposed between the side panels 52. The side panels 52 and the top panel 51 collectively form a U-shaped mounting member 5. A space is formed between the side panels 52 to accommodate the circuit board 4. Mounting slots 55 are provided on the opposing side walls of the side panels 52 for inserting the edges of the circuit board 4.

[0056] The specific formation of the assembly groove 55 is as follows: Figure 6 As shown, the top plate portion 51 of the mounting member 5 is provided with a first rib 53 extending in the first direction, and the inner sidewalls of the side plates 52 are provided with a second rib 54 extending in the first direction. Spaced apart between the first and second ribs 53, 54 are assembly slots 55 extending in the first direction for insertion of the two ends of the circuit board 4. When the ends of the circuit board 4 are inserted into the assembly slots 55, the circuit board 4 is restrained by the assembly slots 55 in the second and third directions, preventing it from escaping from the mounting member 5 in the second and third directions.

[0057] In addition, in order to prevent the circuit board 4 from falling out of the assembly groove 55 along the first direction, one of the assembly groove 55 and the circuit board 4 is provided with a positioning block 56, and the other is provided with a positioning groove 41 for the positioning block 56 to be engaged; for example, Figure 6 As shown, in this embodiment, the positioning block 56 is provided in the assembly groove 55 , and the positioning groove 41 is provided at the end of the circuit board 4 .

[0058] When the positioning block 56 is inserted into the positioning slot 41 , the circuit board 4 and the mounting member 5 maintain relative positioning in the extending direction of the assembly slot 55 , i.e., the first direction. That is, the circuit board 4 cannot directly slide out of the assembly slot 55 along the first direction.

[0059] It is understandable that the mounting member 5 itself has a certain degree of elasticity, that is, the two side plates 52 can be forced to move closer to each other or away from each other by a certain distance. For example, the mounting member 5 is made of plastic or metal.

[0060] When assembling the circuit board 4, force can be applied to control the two side panels 52 to move away from each other to expand the distance between the two side panels 52, and then the circuit board 4 is placed in the corresponding assembly groove 55 position between the two side panels 52, and the positioning block 56 and the positioning groove 41 are aligned, and then the side panels 52 are loosened. The side panels 52 are reset under their own elastic force, so that the positioning block 56 is stuck in the positioning groove 41. At this time, the circuit board 4 is stuck in the mounting component 5 and cannot be dislodged, thereby completing the assembly of the circuit board 4.

[0061] The mounting member 5 with the circuit board 4 assembled thereon can be inserted into the sliding groove 212 of the bracket 21 along the first direction for assembly.

[0062] In order to achieve a detachable connection between the connecting member 3 and the bracket 21, in some embodiments, such as Figure 7 As shown, the connecting member 3 includes a slot 311 for the end of the bracket 21 to be inserted into along the first direction; a plug 312 is provided in the slot 311 and can be inserted into the slide groove 212 along the first direction. Specifically:

[0063] The connecting member 3 includes a first connecting portion 31 and a second connecting portion 32. In some embodiments, the first connecting portion 31 and the second connecting portion 32 are integrally formed. A slot 311 is provided on the first connecting portion 31. During assembly, the slot 311 of the connecting member 3 is aligned with the end of the bracket 21. The plug 312 then aligns with the end of the slot 212. The connecting member 3 is then inserted into the end of the bracket 21 along the first direction. The plug 312 then fits into the slot 212. The plug 312 and the slot 212 form an interference fit, ensuring a relatively secure insertion of the connecting member 3 into the end of the bracket 21.

[0064] In addition, in order to facilitate the installation of the entire fan module 2 on the radiator body 1, in some embodiments, the second connecting portion 32 is improved to a certain extent. Specifically:

[0065] The second connection portion 32 includes two clamping feet 321 arranged opposite to each other along the second direction. The clamping feet 321 have elastic deformation capability. For example, the clamping feet 321 can be made of a plastic part or a metal part with a certain elastic force.

[0066] like Figure 8As shown, the two clamping feet 321 are used to be inserted between the two waterway plates 11, and are respectively clamped to the concave steps 111 on the opposite side walls of the two waterway plates 11 under the action of their own elastic force. Generally speaking, a number of concave groove areas are formed on both the inner and outer sides of the waterway plates 11 of the existing radiator body 1, so that the end surfaces of the two ends of the groove area constitute the said concave steps 111; it can be seen that the clamping feet 321 are clamped to the concave steps 111 of the waterway plates 11 of the radiator body 1, so there is no need to set an additional clamping part on the radiator body 1 for the connecting member 3 to be clamped.

[0067] The structures of the two locking pins 321 are basically the same, so this embodiment takes one of them as an example for description:

[0068] The clamping foot 321 is at least partially bent toward the side away from the other clamping foot 321 to form a bent section 322. The end of the bent section 322 is bent toward the clamping foot 321, and the bent position forms a convex portion 323. In the assembled state, the clamping foot 321 is clamped into the concave step 111 through the convex portion 323 to achieve clamping connection with the waterway plate 11.

[0069] In order to guide the clamping foot 321 to be inserted between the two water channel plates 11 , the surface of the bent section 322 away from the first connecting portion 31 is an inclined guiding surface.

[0070] During assembly, the second connecting portion 32 is inserted upward from the bottom of the radiator body 1 between the two waterway plates 11. During the insertion process, the two clamping feet 321 are squeezed by the waterway plates 11 and moved closer to each other until the convex portion 323 of the clamping foot 321 enters the concave step 111. The two clamping feet 321 move away from each other under their own elastic force, so that the convex portion 323 is clamped into the concave step 111 to achieve clamping. Figure 8 Status shown.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
