[0002] CT examination is a relatively advanced medical scanning examination technology in modern times. It is mainly used for scanning the human body. A detector module and a ray emitting device are installed inside the device. A large amount of heat is generated during its operation. The accumulation of heat easily leads to too high a temperature inside the box. Therefore, a heat dissipation mechanism is generally provided in the outer shell of the CT equipment;

[0003] Chinese Patent Grant Publication No. CN 219145947 U discloses a heat dissipation device for CT equipment, including a main body. A scanning chamber is fixed between the inner walls of the main body. A spiral tube is fixed on the outer peripheral wall of the scanning chamber. A cavity is opened inside the peripheral wall of the spiral tube. An internal water tank is fixed on the inner bottom wall of the main body. A water pump is fixed on the inner bottom wall of the main body. Through the cooperation of air cooling and water cooling, the heat dissipation effect of the equipment can be effectively improved.

The above existing technical solutions have the following deficiencies: This device blows air to the serpentine tube through an exhaust fan in cooperation with air inlet holes, etc. However, since the exhaust fan is arranged on one side of the serpentine tube and the number is single, the hot air inside the shell cannot be discharged efficiently and quickly, thereby reducing the heat dissipation effect on the serpentine tube and the inside of the shell. Therefore, there is a certain improvement plan. Summary of the Utility Model

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4 , an embodiment provided by the present utility model: a heat dissipation mechanism for a CT device, including a housing 1, a scanning chamber 2 is arranged inside the housing 1, support seats 4 are installed on both the front and rear sides of the bottom end of the housing 1, and a heat exchanger 5 is connected to the same side of the two support seats 4. A cooling coil 3 is sleeved on the outer periphery of the scanning chamber 2, and the water inlet and outlet ends of the cooling coil 3 are respectively connected to the water inlet and outlet ends of the heat exchanger 5. Heat dissipation fans 7 are evenly installed at one end of the housing 1, heat dissipation holes 9 are evenly opened at the other end of the housing 1, and the positions of the heat dissipation holes 9 correspond to those of the heat dissipation fans 7 one by one. Guide plates 6 are evenly installed on the outer side of the cooling coil 3, and the guide plates 6 are spirally distributed outside the cooling coil 3. At the same time, the air outlet of the heat dissipation fan 7 faces the gap between adjacent guide plates 6. A plurality of heat conduction mechanisms 8 are arranged on the outer side of the housing 1 at equal intervals in a circular shape;

[0023] The heat conduction mechanism 8 includes two L-shaped connecting pipes 801 penetrating through the outer side of the housing 1, and one end of the two L-shaped connecting pipes 801 is close to the outer peripheral wall of the scanning chamber 2. The other ends of the two L-shaped connecting pipes 801 are connected to a heat dissipation pipe 802, and heat dissipation fins 803 are evenly installed on the outside of the heat dissipation pipe 802;

[0024] The material of the heat dissipation pipe 802 is copper. The heat dissipation fins 803 are evenly distributed in a circular shape at equal intervals on the outside of the heat dissipation pipe 802. The heat dissipation fins 803 and the two heat dissipation pipes 802 form a U-shaped structure;

[0025] Specifically, as Figure 1 , Figure 2 shown, when in use, the L-shaped connecting pipes 801 and the heat dissipation pipe 802 are used to further conduct the heat inside the housing 1, so that the heat inside the heat dissipation pipe 802 is separated from the housing 1 as much as possible, and then contacts the heat dissipation fins 803 to quickly cool down this part of the heat;

[0026] A guide groove 10 is opened on one side of the housing 1 close to the heat dissipation hole 9, and a guide ring 11 is installed inside the guide groove 10;

[0027] The cross-sections of the guide groove 10 and the guide ring 11 are both circular rings. The rotating plate 12 forms a rotating structure with the housing 1 through the cooperation of the guide groove 10 and the guide ring 11;

[0028] A rotating plate 12 is installed on the outer side of the guiding ring 11, and docking holes 13 are respectively formed inside the rotating plate 12. Filter meshes 16 are installed inside the docking holes 13. A rotating ring 14 is installed on the outer edge of the rotating plate 12 close to one side of the housing 1, and the rotating ring 14 is sleeved on one end of the housing 1. An adjusting and fixing mechanism 15 is connected between one side of the rotating ring 14 and the outer side of the housing 1;

[0029] The inner diameter of the rotating ring 14 is adapted to the outer diameter of the housing 1, and at the same time, the inner wall of the rotating ring 14 abuts against the outer wall of the housing 1;

[0030] The adjusting and fixing mechanism 15 includes a guiding hole 1505 formed on one side of the rotating ring 14, and locking grooves 1506 are evenly formed on both sides of the guiding hole 1505. A groove 1501 is correspondingly formed on one side edge of the housing 1, and a sliding block 1502 is slidably installed inside the groove 1501. An adjusting rod 1503 is installed at the top end of the sliding block 1502, and the top end of the adjusting rod 1503 penetrates through the guiding hole 1505. A locking block 1504 is rotatably connected to the outside of the adjusting rod 1503, and both ends of the locking block 1504 respectively extend into the internal parts of the corresponding locking grooves 1506 on both sides;

[0031] The locking grooves 1506 are continuously and adjacently distributed on the guiding hole 1505. The top view cross section of the locking block 1504 is fusiform, and the top view cross section of the locking groove 1506 is triangular;

[0032] Specifically, as Figure 1 、 Figure 3 and Figure 4 shown, during use, the insertion correspondence between the locking block 1504 and the locking grooves 1506 at different positions is utilized to realize the adjustment of the rotation angle of the rotating plate 12, so that the misalignment angle between the docking holes 13 and the heat dissipation holes 9 is changed.

[0033] Working principle: When the present utility model is in use, first, the heat exchanger 5 is started, so that the condensate inside the cooling coil 3 flows inside the cooling coil 3, and then the heat on the scanning chamber 2 is absorbed under the liquid cooling effect. The heat dissipation fan 7 is started, so that the air flow inside the housing 1 flows towards the front end of the housing 1, and the heat inside the housing 1 is guided along the guiding plate 6 and passes through the periphery of the cooling coil 3, and the heat in the cooling coil 3 is transferred outwards through the heat dissipation holes 9;

[0034] Secondly, due to the expansion effect of the hot air flow, part of the distributed heat outside the scanning chamber 2 and not in contact with the cooling coil 3 can enter the inside of the heat dissipation pipe 802 along the L-shaped connecting pipe 801. Since the heat dissipation pipe 802 is separated from the housing 1, the heat dissipation pipe 802 can dissipate heat quickly under the action of the heat dissipation fins 803 to improve the heat dissipation rate;

[0035] Finally, pull the adjusting rod 1503 outwards to move the locking block 1504 out of the inside of the locking groove 1506. Then rotate the rotating ring 14 to make the rotating plate 12 rotate to the docking hole 13, and then misalign the docking hole 13 with the heat dissipation hole 9 to change the size of the ventilation inlet and outlet. Then press the adjusting rod 1503 downwards to insert the locking block 1504 into the inside of the locking groove 1506 to fix the position of the rotating plate 12.
