Description

Technical Field

[0001] This utility model belongs to the field of louver technology, and in particular a heat dissipation louver. Background Technology

[0002] During the grinding process, the flap wheel needs to be in contact with the object surface for a long time. It heats up rapidly during grinding, and the high temperature will accelerate the wear and shedding of abrasive grains, reduce cutting ability, and cause discoloration of the workpiece surface. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a heat dissipation louver wheel that features excellent heat dissipation.

[0004] The objective of this utility model can be achieved through the following technical solutions: A heat dissipation louver, comprising: The substrate has a recessed portion and a flat portion, the flat portion is arranged around the recessed portion, a connecting hole is provided at the bottom of the recessed portion, a plurality of through holes are provided on the side wall of the recessed portion, and a plurality of reinforcing ribs are provided on the substrate, the reinforcing ribs extend from the side wall of the recessed portion to the flat portion, and the reinforcing ribs are close to the edge of the through holes on one side of the side wall of the recessed portion. Several grinding discs, arranged in a circumferential array, are fixed on the planar portion.

[0005] In the aforementioned heat dissipation louver, several AC holes are provided on the flat part.

[0006] In the aforementioned heat dissipation louver, a plurality of AC holes are arranged in a circumferential array on the planar portion.

[0007] In the aforementioned heat dissipation louver, two reinforcing rings are fixed on the flat part, and the two reinforcing rings are respectively arranged on both sides of the AC hole.

[0008] In the aforementioned heat dissipation louvers, there is a reinforcing rib between adjacent AC holes.

[0009] In the aforementioned heat dissipation louver, the grinding disc covers the AC port.

[0010] Compared with the prior art, this application has the following advantages: In this application, several through holes on the sidewall of the recess can form an air convection channel when the flap wheel rotates at high speed, which accelerates the dissipation of heat generated during the grinding process, extends the effective cutting time of the grinding disc, and at the same time prevents the workpiece from rising to a high temperature in a short time, which could lead to quality problems such as discoloration. The reinforcing ribs on the substrate extend from the sidewall of the recess to the flat part and are close to the edge of the through holes. This not only compensates for the impact of the through holes on the structural strength of the substrate, but also enhances the overall rigidity. At the same time, during the rotation, the reinforcing ribs also act as fan blades to enhance airflow. Attached Figure Description

Detailed Implementation

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] like Figures 1 to 2 As shown, a heat dissipation louver includes: a base 2 and several grinding discs 3. The base 2 has a recessed portion 21 and a flat portion 22. The flat portion 22 is arranged around the recessed portion 21. A connecting hole 211 is opened at the bottom of the recessed portion 21. Several through holes 212 are opened on the side wall of the recessed portion 21. Several reinforcing ribs 23 are provided on the base 2. The reinforcing ribs 23 extend from the side wall of the recessed portion 21 to the flat portion 22, and the reinforcing ribs 23 and the side wall of the recessed portion 21 are close to the edge of the through hole 212. Several grinding discs 3 are circumferentially arrayed and fixed on the flat portion 22.

[0014] In this application, the several through holes 212 opened on the side wall of the recessed portion 21 can form an air convection channel when the flap wheel rotates at high speed, which accelerates the dissipation of heat generated during the grinding process, extends the effective cutting time of the grinding disc 3, and at the same time avoids the workpiece from rising to a high temperature in a short time, resulting in quality problems such as discoloration. The reinforcing ribs 23 on the base 2 extend from the side wall of the recessed portion 21 to the flat portion 22 and are close to the edge of the through holes 212. This not only makes up for the impact of the opening of the through holes 212 on the structural strength of the base 2, but also enhances the overall rigidity. At the same time, during the rotation process, the reinforcing ribs 23 also act as fan blades to enhance airflow.

[0015] Specifically, the flat part 22 has a number of communication holes 221.

[0016] The flat portion 22 is the main area of ​​contact between the grinding disc 3 and the workpiece, and it is also the area where heat is concentrated. After the air exchange hole 221 is opened, it can form a "three-dimensional heat dissipation channel" with the through hole 212 on the side wall of the recessed portion 21. When rotating at high speed, air flows through the through hole 212 of the recessed portion 21, and can also directly carry away the heat generated by the grinding disc 3 through the air exchange hole 221 of the flat portion 22, reducing the accumulation of heat in the flat portion 22 and the grinding disc 3, and further reducing the impact of high temperature on abrasive wear and shedding.

[0017] Specifically, a plurality of AC ports 221 are arranged in a circumferential array on the planar portion 22.

[0018] The layout of the circumferential array matches the circumferential distribution of the grinding disc 3, which allows the AC holes 221 to be evenly distributed in various areas of the planar portion 22.

[0019] Specifically, two reinforcing rings 222 are fixed on the flat part 22, and the two reinforcing rings 222 are respectively arranged on both sides of the AC hole 221.

[0020] While the opening of the AC port 221 improves heat dissipation, it may weaken the overall rigidity of the flat part 22 to some extent. The two reinforcing rings 222 are located on both sides of the AC port 221, which can form support for the AC port 221 area and enhance the structural strength of the area.

[0021] Specifically, there is a reinforcing rib 23 between adjacent AC ports 221.

[0022] Specifically, the grinding disc 3 covers the AC port 221. Air passes through the AC port 221, directly carrying away localized heat from the back of the grinding disc 3, thus achieving a heat dissipation effect.

[0023] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure.
