[0033] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Example 1

[0035] To facilitate easy installation of the fan onto the heatsink body 1, refer to... Figure 1-7 As shown, this embodiment provides a radiator fan module mounting structure, which includes a radiator body 1 and a fan module 2.

[0036] The radiator body 1 includes two water channel plates 11 arranged opposite each other along a first direction. In other words, the first direction is the relative direction of the two water channel plates 11.

[0037] It is understood that the water channel plate 11 is used to provide a water channel for the circulation of heat medium, that is, a water channel for the circulation of heat medium (such as hot water or steam) is provided inside the water channel plate 11. During the circulation of heat medium in the water channel, heat is dissipated through the water channel plate 11 and the heat dissipation fins provided on the inner side wall of the water channel plate 11 to provide heating.

[0038] The two water channel plates 11 have a first concave step 111 and a second concave step 112 on their opposite side walls; for ease of explanation, the opposite side walls of the two water channel plates 11 are referred to as the inner side walls of the water channel plates 11.

[0039] In some embodiments, the first concave step 111 and the second concave step 112 are specifically constructed as follows: the waterway plate 11 includes a main waterway extending in a direction perpendicular to the first direction, combined with... Figure 3 and Figure 4 As shown, the portion of the water channel plate 11 that forms the main water channel protrudes inward to form a protrusion 110 that protrudes from the inner sidewall of the water channel plate 11. The upper end face of the protrusion 110 forms a first concave step 111, and the lower end face forms a second concave step 112.

[0040] It is worth noting that, generally speaking, in some existing radiator water channel plates 11, the protrusions 110 are usually present to form the main water channel. That is to say, in this embodiment, the formation of the first concave step 111 and the second concave step 112 does not require additional processing of the water channel plate 11, and they are formed by the protrusions 110 that are inherent to the water channel plate 11.

[0041] like Figure 5 and Figure 6 As shown, in this embodiment, the fan module 2 includes a cover plate 22 and one or more fan bodies 21 connected to the cover plate 22; wherein each of the fan bodies 21 is sequentially disposed on the cover plate 22 along the length direction of the cover plate 22; it is worth noting that the specific number of fan bodies 21 is determined according to actual needs, for example, this embodiment shows the case of using 4 fan bodies 21; correspondingly, the cover plate 22 has a vent 221 at the position corresponding to the fan body 21, that is, one fan body 21 corresponds to one vent 221.

[0042] In some embodiments, the fan body 21 may be mounted on the cover plate 22 by means of screw connection.

[0043] The fan module 2 has one or more retaining members 3 on both sides. In other words, each side of the fan module 2 has one or more retaining tooth members, and the retaining members 3 on both sides are basically symmetrically arranged.

[0044] In some embodiments, the retaining member 3 is fixed to both sides of the cover plate 22. For example, the retaining member 3 and the cover plate 22 are an integral structure, or the retaining member 3 is installed on the cover plate 22 by screws.

[0045] Combination Figure 4 As shown, the holding member 3 includes a first locking foot 31 that can be locked into the first concave step 111; the first locking foot 31 can undergo elastic deformation along a first direction. For example, the holding member 3 is an integral structure, and the entire holding member 3 is made of a material with elastic deformation capability, such as elastic plastic or hard metal.

[0046] In the assembled state, the first locking pin 31 engages with the first recess 111 to mount the fan module 2 onto the heatsink body 1. Specifically:

[0047] During installation, the first locking foot 31 is inserted from the lower side of the water channel plate 11 between the two water channel plates 11. Under the pressure of the protrusion 110, the two first locking feet 31 on opposite sides deform toward each other. When the first locking foot 31 reaches the position of the first concave step 111, the first locking foot 31 resets under its own elasticity, thereby locking into the first concave step 111 to achieve a snap-fit, thereby fixing the fan module 2 to the water channel plate 11.

[0048] In some embodiments, the holding member 3 further includes a second locking foot 33 for locking onto the second concave step 112; when the second locking foot 33 is locked onto the second concave step 112, the first locking foot 31 is locked onto the first concave step 111.

[0049] In this embodiment, the function of the second locking pin 33 and the second concave step 112 is essentially to position the first locking pin 31, that is, to limit the insertion of the first locking pin 31 too deeply. Figure 4 Taking the perspective direction as an example, it means that the first locking pin 31 is restricted from being inserted too deeply upwards. When the second locking pin 33 is inserted upwards to the second concave step 112, the second locking pin 33 will be restricted from being inserted upwards due to the obstruction of the second concave step 112, thereby restricting the first locking pin 31 from being inserted upwards, preventing the first locking pin 31 from being inserted upwards after reaching the first concave step 111.

[0050] like Figure 4 As shown, in order to allow the first locking foot 31 of the locking member 3 to smoothly pass over the second concave step 112 during insertion, in some embodiments, the end of the first locking foot 31 is bent and tilted towards the side closer to the fan module 2 to form a guide portion 32, and / or the second concave step 112 is an inclined slope, the inclination direction of which is to gradually approach the fan module 2 from bottom to top.

[0051] For ease of understanding, Figure 4 Taking the shown viewpoint as an example, the guide part 32 bends and tilts to the right, and the slope of the second concave step 112 tilts to the right.

[0052] It is worth noting that the "bottom-up" approach claimed in this embodiment refers to the definition of the radiator in its normal placement state. The radiator in its normal placement state, i.e. Figure 4 As shown, fan module 2 is located at the bottom of heatsink body 1.

[0053] Both the guide portion 32 and the inclined surface of the second concave step 112 are used to guide the first locking foot 31 over the second concave step 112; for example, as Figure 4 As shown, when the first locking foot 31 is inserted upward between the two water channel plates 11, the guide part 32 will first contact the inclined surface of the second concave step 112. As it is continuously inserted upward, under the action of the inclined surface of the second concave step 112 and the guide part 32, the first locking foot 31 will be pushed to deform towards the side of the fan module 2, so as to eventually cross the second concave step 112.

[0054] Similarly, such as Figure 3 As shown, in order to allow the first latch 31 to be smoothly removed from the first recess 111 when the fan module 2 needs to be disassembled later, the first recess 111 includes a first latching surface 111a for the first latch 31 to latch, the first latching surface 111a being an inclined surface that gradually moves away from the fan module 2 from bottom to top; and / or the first latch 31 is inclined, the inclination direction being that it gradually moves away from the fan module 2 from bottom to top.

[0055] When the fan module 2 is pulled down, the tilted first contact surface 111a and the first locking foot 31 can be guided to continuously disengage from each other, so that the first locking foot 31 is pulled off the first contact surface 111a.

[0056] Example 2

[0057] See Figure 1-7 As shown, this embodiment further provides a heat sink based on embodiment 1, including a heat sink body 1 and a fan module 2. The heat sink body 1 and the fan module 2 are assembled using the heat sink fan module 2 mounting structure described in embodiment 1.
