[0048] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0049] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0050] The following is combined with Figure 1-10 The present invention is described in further detail.

[0051] Example 1

[0053] The working principle and beneficial effects of the above technical solution are:

[0054] The internally radiating toothed cooling plate of the present invention has a larger heat dissipation surface area than the conventional cooling plate, because the heat of the cooling plate is removed by the medium flowing through the internal heat dissipation channel of the cooling plate. The larger the contact surface with the medium, the more heat is removed and the better the heat dissipation effect. In the present invention, by providing the heat dissipation teeth 3 extending radially inward, the heat dissipation surface area can be greatly increased, and the effect of the medium flowing through the heat dissipation channel in removing heat can be improved, so as to achieve a better heat dissipation effect than the conventional cooling plate.

After completing the cooling, heat exchange and heat dissipation treatment, the medium is discharged through the medium outlet. The medium inlet and the medium outlet are arranged on the first surface and the second surface arranged opposite to each other, forming a straight-through heat exchange and heat dissipation channel 2, which can make the water flow faster and facilitate the arrangement of multiple heat dissipation channels 2. Increasing the number of heat dissipation channels 2 is beneficial to increasing the heat dissipation surface area and improving the effect of the medium flowing through the heat dissipation channel 2 to take away heat, so as to achieve a better heat dissipation effect than traditional water-cooled plates.

Since the multiple medium inlets, heat dissipation channels 2 and medium outlets in the present invention are straight-through structures, there is no need to set up curved pipes. Therefore, a larger number of them can be set up to meet higher heat dissipation requirements.

[0069] The working principle and beneficial effects of the above technical solution are:

[0070] The present invention provides an internal radiation toothed cooling plate, which is internally provided with one or more dividing slides 4 that pass through the heat dissipation channel 2, and each dividing slide 4 is connected to a dividing baffle 5. When the directional channel opening 51 of the dividing baffle 5 is relatively matched with the heat dissipation channel 2, the heat dissipation channel 2 acts as a straight channel in a flow state. At this time, the present invention as a whole is used as a larger cooling heat dissipation plate; when the transverse channel of the changing channel opening 52 can be relatively matched with the side of the heat dissipation channel 2 close to the medium inlet, the vertical channel of the changing channel opening 52 can be relatively set with the auxiliary outlet 7 arranged on the bottom surface of the cooling substrate 1. At this time, a heat dissipation zone of a certain area is formed between the side of the heat dissipation channel 2 close to the medium inlet and the dividing baffle 5. The heat dissipation medium enters the heat dissipation channel 2 through the medium inlet and is transported to the auxiliary outlet 7 on the bottom surface of the cooling substrate 1 through the changing channel opening 52 that blocks the heat dissipation channel 2, which is convenient for zoning control when the present invention is used. The size of the heat dissipation zone is adjusted according to the area where heat dissipation is required, which can save energy and reduce consumption and improve the heat dissipation effect of the required heat dissipation area to a certain extent.

[0071] Example 6

[0072] like Figure 1-10 As shown, the described internal radiation toothed cooling plate, wherein the control mechanism 6 includes a control worm 61, a transmission worm gear 62, a rotating tube 63 and a fixing stud 64; both ends of the control worm 61 rotate on the cooling substrate 1, and the control worm 61 is engaged with one or more transmission worm gears 62 located in the partition slide 4; the inner side of each transmission worm gear 62 is matched with a rotating tube 63, and the rotating tube 63 is rotated in the partition slide 4 through the hanger 65, and the inner side of the rotating tube 63 is threadedly connected to the fixing stud 64; one end of the fixing stud 64 is fixed on the partition baffle 5.

[0073] The working principle and beneficial effects of the above technical solution are:

[0074] The present invention provides an internal radiation toothed cooling plate, and the structural setting of the control mechanism 6 enables it to control the partition baffles 5 at different positions to slide in the partition slide 4, thereby controlling the present invention to form heat dissipation areas of different sizes, thereby meeting the use requirements in different situations, and is easy to operate and highly practical; when in use, rotating the control worm 61 can drive the transmission worm gear 62 to rotate, and when the transmission worm gear 62 rotates, it can drive the rotating tube 63 to rotate, and when the rotating tube 63 rotates, it can change its contact position with the fixed stud 64, thereby driving the fixed stud 64 to perform horizontal displacement movement, thereby driving the partition baffle 5 to slide in the partition slide 4 through the fixed stud 64, and the controller separates the heat dissipation channel 2.

[0075] Example 7

[0076] like Figure 1-10As shown, the internal radiation toothed cooling plate, wherein the rotating tube 63 includes an internal threaded tube body 631, the inner end of the internal threaded tube body 631 rotates on the hanger 65, the outer end of the internal threaded tube body 631 is fixed with an outer retaining ring 632, and the thread on the outer retaining ring 632 cooperates with the linkage column 633; ​​the internal threaded tube body 631 rotates in the through-axis hole of the transmission worm gear 62, and the transmission worm gear 62 is provided with a linkage socket that can be plugged in and matched with the linkage column 633.

[0077] The working principle and beneficial effects of the above technical solution are:

[0078] The present invention provides an internal radiation toothed cooling plate, and the structural setting of the rotating tube 63 is such that when the transmission worm gear 62 rotates, the rotating tube 63 at the corresponding position can be driven to rotate, thereby controlling the partition baffle 5 matched therewith, or the rotating tube 63 at the corresponding position can be driven not to rotate, so that only the rotating tube 63 required to be driven can be driven to rotate, thereby achieving more precise control; when the transmission worm gear 62 needs to rotate to drive the rotating tube 63 at the corresponding position to rotate, the linkage column 633 is rotated to be inserted into the linkage socket of the transmission worm gear 62. At this time, when the transmission worm gear 62 rotates, the internal threaded tube body 631 can be driven to rotate through the cooperation of the linkage column 633 and the outer retaining ring 632; conversely, the linkage column 633 can be controlled to disengage from the linkage socket of the transmission worm gear 62.

[0079] In the inner radiation toothed cooling plate, a tensioning spring 66 is sleeved on the fixing stud 64 , and two ends of the tensioning spring 66 are respectively in contact with the hanger 65 and the partition baffle 5 .

[0080] The working principle and beneficial effects of the above technical solution are:

[0081] In an internal radiation toothed cooling plate of the present invention, a tensioning spring 66 is sleeved on the fixing stud 64, and the two ends of the tensioning spring 66 are respectively abutted against the hanger 65 and the partition baffle 5, which is beneficial to improve the stability of the partition baffle 5 under normal conditions, or to improve the stability of the partition baffle 5 after the fixing stud 64 drives the movement.

[0084] The working principle and beneficial effects of the above technical solution are:

[0085] In an internal radiation toothed cooling plate of the present invention, the tension spring 535 remains in a stretched state under normal conditions. When the partition baffle 5 drives the redirecting channel opening 52 to move above the auxiliary outlet 7, the pipe body 531 can slide downward to the guide opening of the vertical channel under the elastic force of the tension spring 535, and insert the position with the inclined surface 536 into the auxiliary outlet 7. At this time, the movement of the partition baffle 5 is completed, and there is no need to continue to adjust the position of the partition baffle 5. Then the output pipe can be connected to the pipe body 531. The inner side of the pipe body 531 is provided with an inner The threaded part is convenient for connection with the output pipe to facilitate the output of the medium; when the redirecting channel opening 52 is not needed, the partition baffle 5 is controlled to return to its original position. Since the lower end of the connecting pipe body 531 is provided with a downward inclined surface 536, the partition baffle 5 can squeeze the inclined surface 536 at the lower end of the connecting pipe body 531 through the auxiliary outlet 7 when it moves, so that the connecting pipe body 531 moves upward and is re-entered into the guide opening in the vertical channel. At this time, the tension spring 535 is re-stretched to facilitate the control of the connecting pipe body 531 to slide out for use next time.

The process is complicated, the quality consistency is poor, the production efficiency is also very low, and the copper material with a price more than twice that of aluminum is used, so the cost is relatively high.
