Abstract

The utility model relates to the technical field of heat sinks, and specifically to an aluminum profile heat sink with a multi-layer fin structure, comprising a mounting frame and a heat sink body: a dust protection mechanism is arranged on the side of the heat sink body, and a portable mounting mechanism is arranged on the side of the dust protection mechanism. When the aluminum profile heat sink with the multi-layer fin structure is in use, the outer wall of one side of the protective outer frame is arranged as a porous filter screen structure, and the filter screen is used to isolate dust so that dust is not easy to enter the inside of the heat sink. The protective outer frame is further arranged as a detachable design.

After cleaning, it can be reinstalled on the outside of the heat sink to continue to achieve the dust prevention effect. On the basis of ensuring the cleanliness of the inside of the heat sink, the normal heat dissipation effect of the heat sink is further guaranteed. The overall structure is simple and the use effect is good.

Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to an aluminum profile heat sink with a multi-layer fin structure. Background Art

[0002] Aluminum heat sinks with multi-layer fin structures are metal products used for heat dissipation. By making aluminum materials into multi-layer fin structures, the surface area is increased, thereby improving the heat dissipation efficiency. This type of heat sink is usually used in electronic equipment, automobile engines and other occasions where heat dissipation is required. It can effectively transfer heat to the external environment to prevent equipment from overheating and damage. Aluminum heat sinks with multi-layer fin structures have the advantages of high heat dissipation efficiency, light weight, and corrosion resistance, and are widely used in various fields.

[0003] Patent No. "CN207733178U" discloses "an aluminum profile heat sink". The device forms a heat dissipation channel by forming a sealing plate with through holes at both ends of the horizontal rectangular aluminum profile and the vertical rectangular aluminum profile that constitute a rectangular frame. The heat dissipation effect is good, and the horizontal ribs and vertical ribs in the rectangular frame effectively enhance the overall structural strength to avoid extrusion deformation; however, since the aluminum profile heat sinks are all exposed, as the years of use increase, a large amount of dust and impurities are easily accumulated inside. At the same time, due to the compact structure of the aluminum profile heat sink, once a large amount of dust and impurities are accumulated, it is extremely difficult to clean, and a large amount of dust and impurities accumulated inside the aluminum profile heat sink will also affect its normal heat dissipation effect. However, the above-mentioned device has not made improvements to this problem, and the overall practical effect is poor. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problem and to propose an aluminum profile heat sink with a multi-layer fin structure, which improves the problem that the aluminum profile heat sinks in the prior art are all exposed. As the years of use increase, a large amount of dust and impurities are easily accumulated inside. Since the aluminum profile heat sink has a compact structure, it is extremely difficult to clean up once a large amount of dust and impurities are accumulated, and a large amount of dust and impurities accumulated inside the aluminum profile heat sink will also affect its normal heat dissipation effect.

[0005] A multi-layer fin structure of aluminum profile heat sink, comprising a mounting frame and a heat sink body: the mounting frame has heat sink bodies arranged at equal intervals inside, and heat sink grooves are symmetrically and evenly spaced on the outer walls on both sides of the heat sink body; a dustproof protection mechanism is arranged on the side of the heat sink body, a portable mounting mechanism is arranged on the side of the dustproof protection mechanism, and a locking control mechanism is arranged on the side of the portable mounting mechanism; the dustproof protection mechanism comprises a protective outer frame, a resistance clamping column, a positioning support frame and a resistance clamping groove; a protective outer frame is slidably mounted on the side outer wall of the mounting frame, two groups of resistance clamping columns are symmetrically arranged on the side outer wall of the protective outer frame, a positioning support frame is arranged on the side outer wall of the mounting frame, and two groups of resistance clamping grooves are symmetrically opened on the side outer wall of the positioning support frame, and the resistance clamping column and the resistance clamping groove are mounted in a snap-fit ​​manner.

[0006] Preferably, both side outer walls of the positioning support frame are configured as open structures, and one side outer wall of the positioning support frame is configured as a porous filter structure.

[0007] Preferably, the portable mounting mechanism includes a positioning support plate and a limiting T-shaped strip, the side of the heat sink body is provided with a positioning support plate, the side outer wall of the positioning support plate is provided with a limiting T-shaped strip, and the top outer wall of the limiting T-shaped strip is connected to the bottom outer wall of the heat sink body.

[0008] Preferably, the side outer wall of the installation frame at the bottom is provided with placement grooves at equal intervals, the side outer wall of the installation frame at the placement groove is provided with a limiting T-shaped groove, the positioning support plate and the placement groove are snap-fitted, and the limiting T-shaped bar and the limiting T-shaped groove are slidably mounted.

[0009] Preferably, the side outer wall of the limiting T-shaped strip is configured as an arc structure, and the side inner wall of the limiting T-shaped groove is configured as an arc structure.

[0010] Preferably, the locking control mechanism comprises a first thread groove and a second thread groove, the side outer wall of the installation frame located at the placement groove is provided with a first thread groove, and the side outer wall of the positioning support plate is provided with a second thread groove.

[0011] Preferably, the first thread groove and the second thread groove are threadedly mounted with the positioning bolt.

[0012] Preferably, the opening diameter of the first thread groove is equal to the opening diameter of the second thread groove.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the aluminum profile heat sink with a multi-layer fin structure is in use, the outer wall of one side of the protective outer frame is set as a porous filter structure, and the filter is used to isolate dust so that dust is not easy to enter the inside of the heat sink. The protective outer frame is further set to a detachable design. Once the filter outside the protective outer frame accumulates too much dust, it can be directly removed from the outside of the device to clean the filter. After cleaning, it can be reinstalled on the outside of the heat sink to continue to achieve the dust-proof effect. In summary, the device can protect the heat sink from dust, and further ensure the normal heat dissipation effect of the heat sink on the basis of ensuring the cleanliness of the inside of the heat sink. The overall structure is simple and the use effect is good.

[0015] 2. When the aluminum profile heat sink with the multi-layer fin structure is in use, the existing mounting frame and heat sink are designed from an integrated setting to a detachable design through the setting of the positioning support plate, the limiting T-shaped bar, the placement groove, the limiting T-shaped groove, the first threaded groove, the second threaded groove and the positioning bolt. Since the protection of the heat sink by the filter mesh cannot ensure that the dust is completely isolated outside the device, the detachable setting of the mounting frame and the heat sink can be used. When dust accumulates inside the heat sink, the mounting frame and the heat sink can be disassembled to achieve all-round cleaning. At the same time, when part of the heat sink is damaged, only a small part of the damaged heat sink needs to be replaced without replacing the entire device. The overall utilization rate is high and the practical effect is good. BRIEF DESCRIPTION OF THE DRAWINGS
