[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0026] In the prior art, there are many components provided in a tumor electro-field therapy instrument. The heat generation of some components is relatively large. If the heat cannot be discharged in time, the excessively high temperature will surely cause damage to the tumor electro-field therapy instrument, seriously affecting the normal operation of the therapy instrument.

[0027] Currently, for heat dissipation of components, a fan is generally used and is provided at the air outlet or air inlet of the housing. The plane where the fan blades are located is parallel to the air outlet or air inlet, and the air flow direction is parallel to the main board inside the housing, and its heat dissipation effect is relatively poor.

[0028] To solve the above technical problems, this application provides a heat dissipation device and a tumor electro-field therapy instrument, which can improve the heat dissipation efficiency and enable the heat inside the cavity to be quickly discharged.

[0029] As Figures 1 to 3 shown, an embodiment of this application provides a heat dissipation device, including a frame body 1, a first cover body 2, and an air duct 3. The frame body 1 is provided with a receiving cavity 11. The frame body 1 is provided with a first air inlet 12 and a first air outlet 13. The first air inlet 12 and the first air outlet 13 are oppositely arranged and both are communicated with the receiving cavity 11. The first cover body 2 covers the receiving cavity 11. A circuit board 21 is provided on the side of the first cover body 2 facing the receiving cavity 11. The air duct 3 is arranged in the receiving cavity 11. The air duct 3 has a second air inlet 31 and a second air outlet 32. The plane where the first air inlet 12 is located is perpendicular to the plane where the second air inlet 31 is located, and the first air inlet 12 faces the circuit board 21. The first air outlet 13 is docked with the second air outlet 32. A turbine fan 33 is provided on the air duct 3 to suck the heat in the receiving cavity 11 from the second air inlet 31 and discharge it through the first air outlet 13.

[0030] It can be understood that when the first cover body 2 is covered on the accommodation cavity 11, the accommodation cavity 11 of the frame body 1 forms a heat dissipation cavity. Under the action of the turbine fan 33, the air in the heat dissipation cavity flows rapidly, and the air outside the frame body 1 enters the accommodation cavity 11 through the first air inlet 12, forming a high-speed air flow. Through the orientation design of the second air inlet 31 and the second air outlet 32 of the air duct 3, the heat generated by the circuit board 21 is sucked into the second air inlet 31 along with the high-speed air flow. Then, under the constraint of the air duct 3, the hot air flow is discharged through the second air outlet 32 and the first air outlet 13 in sequence. Compared with the prior art, the air flow in the heat dissipation cavity can be accelerated, thereby improving the heat dissipation efficiency and quickly discharging the heat in the cavity.

[0031] Optionally, the turning points of the frame body 1 are set to be arc-shaped, and the turning points of the air duct 3 are also set to be arc-shaped to reduce the energy loss caused by eddy currents at the turning points and ensure that the air flow can pass through the heat dissipation cavity and the air duct 3 at high speed.

[0032] Optionally, the cross-section of the frame body 1 is square, so that the heat dissipation cavity forms a straight cylindrical space, and the first air inlet 12 and the second air outlet 32 are arranged opposite to each other. Such an arrangement can greatly reduce the air resistance and is conducive to directly discharging the heat.

[0033] To improve the air circulation rate in the accommodation cavity 11, the first air inlet 12 and the first air outlet 13 can be set to be multiple, and the number of the first air inlet 12 and the first air outlet 13 is not limited here. The shapes of the first air inlet 12 and the first air outlet 13 can be set to be circular, oval, square, diamond-shaped, cross-shaped, etc. As Figure 2 shown, in this embodiment, the shapes of the first air inlet 12 and the first air outlet 13 are set to be cross-shaped.

[0034] Optionally, as Figure 4 shown, the shape of the second air outlet 32 can be set to be circular, oval, square, etc., and is not limited here. In this embodiment, the shape of the second air inlet 31 is set to be circular.

[0035] Furthermore, the plane where the air inlet of the turbine fan 33 is located is parallel to the circuit board 21. The air inlet of the turbine fan 33 is directly opposite to the circuit board 21, so that the hot air flow rises vertically relative to the circuit board 21 and is sucked into the air duct 3 where the turbine fan 33 is located, thereby improving the heat dissipation efficiency.

[0036] In some embodiments, the circuit board 21 has multiple heat - generating areas, and the air inlet of the turbine fan 33 faces the heat - generating area with the highest temperature. A plurality of components are arranged on the circuit board 21, and according to the heat generation amount, they can be set as multiple heat - generating areas. Therefore, by orienting the air inlet of the turbine fan 33 towards the heat - generating area with the highest temperature, the turbine fan 33 can be used to cool the multiple heat - generating areas on the circuit board 21 in a partitioned manner, enabling the components with low temperature resistance and the highest heat - dissipation priority to be cooled first, meeting the heat - dissipation requirements of the components. Other components with high temperature resistance and lower heat - dissipation priority can dissipate heat step - by - step in the heat - dissipation cavity, so that both components with low temperature resistance and those with high temperature resistance can be fully cooled.

[0037] In some embodiments, as Figure 2 and Figure 3 shown, the heat - dissipation device further includes a battery 4. A sleeve 14 is arranged in the housing 1, the battery 4 is installed on the sleeve 14, and heat - dissipation holes 141 communicating with the accommodation cavity 11 are arranged on the sleeve 14. During the use of the battery 4, certain heat will also be generated. By providing the heat - dissipation holes 141, the heat generated by the battery 4 can be discharged out of the housing 1 together with the high - speed air flow through the accommodation cavity 11, thereby ensuring the working reliability of the battery 4.

[0038] Optionally, the battery 4 is a lithium - ion battery 4. The battery core of the lithium - ion battery 4 is cylindrical, and the four sides of the lithium - ion battery 4 are flat. The above shape can greatly reduce the volume of the battery 4, and thus reduce the volume of the tumor electric - field therapeutic apparatus.

[0039] In some embodiments, as Figure 3 shown, the sleeve 14 divides the accommodation cavity 11 into a first heat - dissipation cavity 111 and a second heat - dissipation cavity 112. The air duct 3 is arranged in the first heat - dissipation cavity 111; there are two circuit boards 21, and the heat generation amounts of the two circuit boards 21 are different. One of the circuit boards 21 with a large heat generation amount is arranged in the first heat - dissipation cavity 111, and the other circuit board 21 is arranged in the second heat - dissipation cavity 112.

[0040] The components arranged on the two circuit boards 21 are different, so they have different heat generation amounts. One of the circuit boards 21 with a large heat generation amount is arranged in the first heat - dissipation cavity 111, which is the high - temperature area; the other circuit board 21 is arranged in the second heat - dissipation cavity 112, which is the low - temperature area. By separately arranging the high - temperature area and the low - temperature area, and arranging the air duct 3 and the turbine fan 33 in the high - temperature area, the components with low temperature resistance and the highest heat - dissipation priority can be cooled first, meeting the heat - dissipation requirements of the components. At the same time, the sleeve 14 can also block the heat transfer from the first heat - dissipation cavity 111 to the second heat - dissipation cavity 112 and affect the performance of the components in the second heat - dissipation cavity 112.

[0041] Of course, the air duct 3 and the turbine fan 33 can also be arranged in the second heat - dissipation cavity 112 according to the actual heat - dissipation requirements to meet the heat - dissipation requirements of the components.

[0042] Optionally, the cross-section of the sleeve 14 is also correspondingly set to be square, so that the first heat dissipation cavity 111 and the second heat dissipation cavity 112 form a straight cylindrical space, which can reduce the wind resistance and is beneficial to directly discharge the heat.

[0043] In some embodiments, as Figure 2 shown, the heat dissipation device further includes a second cover body 5. The first cover body 2 and the second cover body 5 are oppositely arranged. The second cover body 5 covers the side of the accommodation cavity 11 away from the first cover body 2. Both the first cover body 2 and the second cover body 5 are detachably connected to the frame body 1 for installation and daily maintenance.

[0044] Optionally, as Figure 3 、 Figure 5 and Figure 6 shown, the frame body 1 is provided with a tongue 15. The tongue 15 has a first end and a second end which are oppositely arranged. A first clamping groove 22 for clamping connection with the first end of the tongue 15 is arranged on the side of the first cover body 2 facing the accommodation cavity 11. A second clamping groove 51 for clamping connection with the second end of the tongue 15 is arranged on the side of the second cover body 5 facing the accommodation cavity 11. Through the clamping connection between the first end of the tongue 15 and the first clamping groove 22, the first cover body 2 can be clamped on the frame body 1 and the displacement of the first cover body 2 in the horizontal direction can be restricted. Through the clamping connection between the second end of the tongue 15 and the second clamping groove 51, the second cover body 5 can be clamped on the frame body 1 and the displacement of the second cover body 5 in the horizontal direction can be restricted, which plays a positioning role and is also convenient for subsequent disassembly and maintenance.

[0045] Optionally, a plurality of first threaded posts 23 are arranged on the side of the first cover body 2 facing the accommodation cavity 11. A plurality of second threaded posts 52 are arranged on the side of the second cover body 5 facing the accommodation cavity 11. The plurality of first threaded posts 23 and the second threaded posts 52 correspond to each other one by one. A fastener is jointly arranged on the first threaded posts 23 and the second threaded posts 52. The fastener can adopt a bolt. By screwing the fastener onto the first threaded posts 23 and the second threaded posts 52, the displacement and rotation of the first cover body 2 and the second cover body 5 in the vertical direction can be restricted.

[0046] The present application also provides a tumor electric field treatment instrument, including the heat dissipation device as described above. By adopting the above heat dissipation device, the heat can be discharged in time to ensure the normal operation of the tumor electric field treatment instrument.

[0047] As Figure 1As shown, the tumor treating electric field apparatus further includes a screen 6. A third card slot (not shown in the figure) is provided on the second cover 5, and the screen 6 is embedded in the third card slot. Optionally, the screen 6 may include a display and a touch panel. If the screen 6 includes a touch panel, the screen 6 can be implemented as a touch screen to receive input signals from the user for parameter setting. The touch panel includes one or more touch sensors to sense touches, swipes, and gestures on the touch panel. The touch sensors can sense not only the boundaries of touch or swipe actions, but also detect the duration and pressure associated with the touch or swipe operations. By providing the screen 6, the parameters to be set and monitored during the treatment process can be displayed.
