Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, in particular to a portable heat dissipation seat with adjustable air volume. Background Art

[0002] In the research and development stage of experimental raw materials, in order to make the mixing process as close to production as possible, and in order to be able to fully and accurately test the various performances of experimental raw materials, it is necessary to use a mixer to mix and mature the experimental raw materials. In order to save the cost of experimental research and development, a smaller mixer will be used to reduce the consumption of experimental raw materials while ensuring that there are enough experimental raw materials required for the test. However, due to the small size of the mixer, there is no space to set up a cooling mechanism. In this way, when the experimental raw materials have a certain viscosity, the experimental raw materials will slowly gather into small groups during the mixing process of the experimental raw materials. This will cause the load of the mixer to increase and the drive motor to heat up easily. When the drive motor overheats, the overheat protection will automatically start. After the overheat protection is started, the mixer stops running. It is necessary to wait until the drive motor cools down to normal temperature (the temperature of the drive motor cools down to below the temperature that triggers the overheat protection) before it can be operated again. The process of the drive motor cooling down to normal temperature naturally takes a long time, which affects the normal feeding and is very inconvenient. Utility Model Content

[0003] Based on this, in order to solve the above problems, the utility model provides a portable heat sink with adjustable air volume.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0006] With the above technical solution, the air circuit board and the adjusting turntable are connected by bolts, and the adjusting turntable can smoothly rotate around the bolts.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 As shown, the utility model is a portable heat sink with adjustable air volume, which is used to accelerate the cooling of the mixer drive motor, including a base 10, an air path plate 20 arranged on the upper surface of the base 10, and an adjustment turntable 30 arranged on the upper surface of the air path plate 20.

[0022] like Figure 1 and Figure 2 As shown, the base 10 is circular. A first air passage 11 is provided in the base 10. An air valve 12 connected to the first air passage 11 is provided on the outer surface of the base 10.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the airway plate 20 is circular. The airway plate 20 has a plurality of second airways 21 in communication with the first airway 11. A plurality of first vent holes 22 are evenly distributed on the edge of the airway plate 20. The first vent holes 22 are in communication with the corresponding second airways 21.

[0024] The base 10 and the gas path plate 20 are fixed by fixing bolts.

[0025] like Figure 2 and Figure 3As shown, the adjusting turntable 30 is provided with a plurality of second air holes 31 which are connected to the positions of the first air holes 22 in a one-to-one correspondence. The provision of the plurality of first air holes 22 and the plurality of second air holes 31 helps to increase the flow rate of cold air and further improve the cooling effect. A step hole 32 is provided in the middle of the adjusting turntable 30. A threaded hole 23 is provided at a position corresponding to the step hole 32 on the air path plate 20. A bolt 33 is provided in the step hole 32. After the end of the bolt 33 passes through the step hole 32, it is screwed into the threaded hole 23 to connect the air path plate 20 and the adjusting turntable 30 together, and the adjusting turntable 30 can rotate around the bolt 33. In this way, Figure 4 , Figure 5 and Figure 6 As shown, by rotating the adjustment turntable 30, the position of the second vent hole 31 and the corresponding position of the first vent hole 22 are completely staggered or partially staggered or overlapped, thereby realizing rapid adjustment of the air volume.

[0026] like Figure 1 As shown, in addition, a cylinder 34 is integrally extended upward from the top periphery of the adjusting turntable 30. The cylinder can play the role of concentrating wind force and increasing wind volume.

[0027] like Figure 3 As shown, the air path plate 20 is provided with a first limiting structure 40 for limiting the rotation range of the adjusting turntable 30. The adjusting turntable 30 is provided with a second limiting structure 41 that cooperates with the first limiting structure 40. In this embodiment, the first limiting structure 40 can be a limiting waist hole. The second limiting structure can be a limiting pin. The limiting waist hole has a first position and a second position. When the limiting pin is located at the first position in the limiting waist hole, the position of the second vent 31 and the position of the corresponding first vent 22 are completely staggered, that is, the second vent 31 is not connected to the first vent 22; when the limiting pin is located at the second position in the limiting waist hole, the position of the second vent 31 and the position of the corresponding first vent 22 coincide, that is, the second vent 31 is connected to the first vent 22. In this way, through the cooperation of the first limiting structure 40 and the second limiting structure 41, the adjusting turntable 30 is subject to certain restrictions when rotating, and will not deviate from the predetermined rotation range, which can prevent the adjusting turntable from rotating excessively when adjusting the air volume.

[0028] like Figure 2 and Figure 3 As shown, a sealing ring 42 is provided between the base 10 and the gas circuit board 20, and between the gas circuit board 20 and the adjusting turntable 30. The use of the sealing ring can effectively enhance the sealing performance between the base and the gas circuit board, and between the gas circuit board and the adjusting turntable to prevent cold air leakage.

[0029] When in use, the base of the mixer is clamped on the cylinder 34 of the adjustment turntable 30. At this time, the second vent 31 is opposite to the heat dissipation hole of the mixer. Then, the air source is connected to the connecting nozzle on the air valve 12, and then the air valve 12 is opened so that the cold air is injected into the first air duct 11 of the base 10. At this time, the limit pin is located at the first position in the limit waist hole, and the second vent 31 is not connected with the first vent 22; then, the adjustment turntable 30 is rotated so that the limit pin is located at the second position in the limit waist hole, and the first vent 22 is connected with the corresponding second vent 31, and the cold air enters the mixer from the heat dissipation hole of the mixer through the second vent 31 to cool the drive motor. Of course, the required air volume can be adjusted by rotating the adjustment turntable according to the actual situation. The structure is simple and easy to operate, and the drive motor of the mixer can be cooled, so that the mixer can be used continuously, thereby improving the use efficiency of the mixer.

[0030] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
