In such an accelerator, a heat sink is generally installed in a dedicated equipment room, and the heat sink is connected to a water circulation system of the accelerator through a water pipe. The water pipe is guided from the fixed frame to the rotating frame through the wire coiling device.
For a medical accelerator capable of continuously rotating, a water pipe cannot be guided from a fixed rack to a rotating rack through a wire coiler, and a common solution is to directly arrange a radiator on the rotating rack of the accelerator and directly blow the radiator through a fan. Since the medical accelerator has a large amount of heat generation, the heat dissipation capability of the radiator is required to be very high, and a plurality of high-speed fans are required to increase the heat dissipation capability. These high speed fans generate very loud noise during operation. In addition, the temperature of accelerator during operation is about 35 degrees, and the difference in temperature with the room temperature is less, is difficult for the heat dissipation, and behind the encapsulation of accelerator casing, the inside heat of accelerator is difficult to distribute away more. In order to achieve a good heat dissipation effect, the temperature requirement of the hospital machine room is very strict, for example, a medical accelerator requires that the temperature of the machine room is below 23 ℃, and the general comfortable room temperature is about 26 ℃.
Therefore, the heat dissipation capability of the current medical accelerator is very limited, and the application range of the medical accelerator is limited due to the harsh environmental requirements, and a new heat dissipation scheme needs to be provided.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example one
As shown in fig. 1 to 6, the present embodiment provides a heat dissipation device for a medical accelerator, which mainly includes a heat dissipation unit 2, a frame unit 3, and a housing 4. The heat radiating unit 2 can be fixedly attached to the accelerator 1 and rotate with the accelerator 1. In the present embodiment, the accelerator 1 is substantially cylindrical, and the heat sink is located behind and fixedly connected to the main body of the accelerator 1. The heat dissipation unit 2 is connected with the frame unit 3 by adopting a revolute pair, and the rotation center of the revolute pair is coaxial with the rotation center of the medical accelerator rotating frame. The frame unit 3 and the heat radiating unit 2 have a coupled state and a separated state. When normally working, the heat radiation unit 2 is connected with the rotating frame of the medical accelerator 1 through screws, and when the accelerator is overhauled, the screws of the heat radiation unit 2 and the accelerator 1 main body can be detached, so that the heat radiation device can be separated from the medical accelerator. The frame unit 3 has a chamber capable of accommodating the heat radiating unit 2 and has at least one inner duct 32 therein. The frame unit 3 further includes a cooling unit 31 which may be provided inside or outside thereof, and cool air generated by the cooling unit 31 can be blown toward the heat radiating unit 2 through an inner duct 32.
In the present embodiment, the frame unit 3 has a plurality of inner air ducts 32, and each inner air duct 32 is provided with a wind pressure adjusting plate and a wind pressure sensor, and the wind pressure adjusting plate can adjust the wind pressure in the inner air ducts 32 according to the wind pressure value obtained by the wind pressure sensor, so that the wind pressures in the plurality of inner air ducts 32 are equal or close to each other. The number of the refrigeration units 31 is equal to the number of the inner air ducts 32, and the inner air ducts are independent of each other. Therefore, the cool air blown to the surface of the heat dissipation unit 2 by the plurality of inner air ducts 32 is evenly distributed, which is beneficial to cooling the heat dissipation unit comprehensively, so as to achieve the best heat dissipation efficiency. In addition, the temperature sensors can be respectively arranged on the air inlet side and the air outlet side of the heat dissipation unit, and the heat dissipation state of the heat dissipation unit is evaluated. The refrigeration unit 31 may employ an air conditioning indoor unit.
The heat sink in this embodiment comprises a housing 4. The housing 4 can house the accelerator 1, the heat radiating unit 2, and the frame unit 3. An outer air duct 41 is formed inside the case 4 so that cool air blown toward the heat radiating unit 2 can be circulated in the outer air duct 41 and then slowly dissipated. The arrangement can lead the cold air passing through the heat radiating unit 2 to be self-circulated in the outer air duct 41 of the shell 4, and avoid the influence on the comfort level of human body caused by blowing to the patient during medical treatment.
With continued reference to fig. 1-6, the heat dissipation unit 2 includes a heat sink 21 that can be fixedly attached to the accelerator 1 and a circulation tank 22 that is fixed to a surface of the heat sink 21. In the present embodiment, the radiator 21 is annular, and therefore the circulation tank 22 is also annular and fixed to the outer end of the radiator 21.
As shown in fig. 7, the circulation tank 22 includes a plurality of small tanks arranged in a ring shape, a communication pipe sequentially connecting the small tanks, a water level detection device disposed on the small tank or on the communication pipe, and a water outlet and a water inlet disposed on the small tank or on the communication pipe.
As shown in fig. 5 to 7, the circulation tank 22 is provided with an automatic relief valve 23, the automatic relief valve 23 includes a relief valve 232 having a valve 231, a first hydraulic cylinder 234 having a first piston 233, a piston rod of the first piston 233 extends out of the first hydraulic cylinder 234 and is associated with the valve 231 so as to control the opening or closing of the valve 231 according to the movement of the first piston 233, and a spring 236 fixedly sleeved on the piston rod of the first piston 233 by a nut 235, so that the piston rod of the first piston 233 is kept in a compressed state (into the first hydraulic cylinder 234) by the spring 236.
The automatic pressure relief valve 23 further comprises a second hydraulic cylinder 238 having a second piston 237, a piston rod of the second piston 237 extending out of the second hydraulic cylinder 238 and being associated with the first piston 233, and a mass ball 239 disposed within the second hydraulic cylinder 238, the mass ball 239 maintaining the piston rod of the second piston 237 a tendency to extend outward by virtue of its own weight.
Therefore, as can be understood by those skilled in the art, the water pipe of the circulating water tank can pass through the inside of the main components of the accelerator, and the heat generated by the operation of the components of the accelerator is taken away. If air exists in the water tank, normal operation of components of the accelerator can be influenced, and even the components of the accelerator are damaged. Through the installation of the automatic air release valve, the accelerator rotates to drive the circulating water tank to rotate together, so that air in the water tank can be discharged, and the normal work of the radiator is ensured without damage. When the circulating water tank rotates along with the accelerator and the second hydraulic cylinder is in an upright state, the gravity of the mass ball is larger than the elastic force of the spring, and the valve is opened, so that the gas in the water tank can be discharged; when the second hydraulic cylinder is not in the vertical state, the gravity of the mass ball applies pressure to the spring, the pressure is smaller than the elastic force of the spring, the valve is not enough to be opened, and the valve is in the closed state, so that liquid in the water tank can be ensured not to leak.
Example two
Referring to fig. 1 and 5, the present embodiment is different from the first embodiment in that the circulation water tank 22 includes a first circulation water tank 221 having a ring shape and a second circulation water tank 222 having a ring shape, and the first circulation water tank 221 is located at the periphery of the second circulation water tank 222. The first circulation water tank 221 and the second circulation water tank 222 are connected in series by a connection pipe.
The first circulation water tank 221 includes a plurality of first small water tanks arranged in a ring shape; the first communicating pipes are sequentially connected with the first small water tanks; the first water level detection device is arranged on the first small water tank or the first communication pipe; and the first water outlet and the first water inlet are arranged on the first small water tank or the first communicating pipe. The second circulation water tank 222 includes a plurality of second small water tanks arranged in a ring shape; the second communicating pipes are sequentially connected with the second small water tanks; a second water level detection device arranged on the second small water tank or the second communicating pipe; a second water outlet and a second water inlet which are arranged on the second small water tank or the second communicating pipe; the first water outlet is communicated with the second water inlet through a third communicating pipe; or the second water outlet is communicated with the first water inlet through a third communicating pipe.
EXAMPLE III
Referring to fig. 8 to 11, the present embodiment is different from the first and second embodiments in that the accelerator 1 is substantially cylindrical, and the heat dissipation unit 2 can be sleeved on the periphery of the accelerator 1 and fixedly connected therewith.
The frame unit 3 and the heat radiating unit 2 have a coupled state and a separated state. When the accelerator 1 is operated, the heat radiating unit 2 is fixed to the accelerator 1 and rotates with the same rotation axis, the heat radiating unit 2 and the frame unit 3 are in a separated state, and the cooling unit 31 blows cool air to the heat radiating unit 2 through the inner duct 32. When accelerator 1 stopped working, the maintainer can dismantle radiating unit 2 from accelerator 1, and then remove it and frame unit 3 through screw fixed connection for maintenance. In practice, the frame element 3 acts as a carrier for the heat dissipating unit 2.
In order to facilitate the movement of the heat dissipating unit 2 and the frame unit 3 fixed together, the frame unit 3 in this embodiment further includes a moving unit 33 provided at the bottom thereof and a guide unit 34 matched with the moving unit 33. Specifically, the moving unit 33 may employ a roller, and the guide unit 34 may employ a guide rail. The laying direction of the guide rails determines the moving direction of the frame unit 3. Thereby, when the frame unit 3 and the heat radiating unit 2 are in a coupled state, the frame unit 3 can move along the guide unit 34 carrying the heat radiating unit 2.
Example four
The present embodiment is different from the first, second and third embodiments in that when the frame unit 3 and the heat dissipating unit 2 are in a separated state, i.e. the heat dissipating unit 2 and the accelerator 1 are fixedly connected together, the frame unit 3 can still move along the guiding unit 34 by means of the moving unit 33, so that the position of the frame unit 3 relative to the heat dissipating unit 2 can be adjusted, thereby facilitating the inner air duct 32 to be better aligned with the heat dissipating unit 2 to deliver cool air thereto.
EXAMPLE five
Referring to fig. 12 to 13, the present embodiment is different from the first and third embodiments in that a cooling unit 31 is provided outside the frame unit 3 and is connected to an inner duct 32 in the frame unit 3 through an additional ventilation duct 5. Therefore, the cooling unit 31 can be disposed outside the room where the accelerator is located. Furthermore, the ventilation duct 5 may not be connected to the cooling unit 31, but may be provided at an air port to cool the heat dissipation unit 2 by natural air blowing.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
