Description

An electron accelerator internal cooling device

technical field

The invention relates to an electron accelerator internal cooling device, which belongs to the technical field of electron accelerators.

Background technique

As the application of irradiation processing becomes more and more extensive, the development of industrialization promotes the improvement of the performance and power of electron accelerators. As the power of electron accelerators continues to increase, the daily effect inside the accelerator becomes more and more significant. At present, a condenser is generally added inside the accelerator, and a fan is installed on the condenser, and a mixed flow is formed inside the accelerator through the fan, and the flowing air passes through the surface of the surface cooler to form heat exchange cooling. As the power of the accelerator continues to increase, the thermal effect generated inside the accelerator will become more significant. Of course, the heat dissipation area of the surface cooler and the air volume of the fan can be increased to meet the requirements of the electron accelerator, but this method obviously cannot keep up. Contemporary energy-saving and environmental protection requirements, so the existing cooling device can not meet the requirements of use.

Contents of the invention

The technical problem to be solved by the present invention is to provide a cooling device inside the electron accelerator, which can greatly improve the cooling efficiency inside the electron accelerator, reduce energy consumption, and ensure the operation quality of the electron accelerator.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

An internal cooling device for an electron accelerator, comprising an accelerator housing, an upper base plate and a lower base plate are arranged in the accelerator housing, a surface cooler is arranged between the upper and lower base plates, and a plurality of motors are arranged in the surface cooler, Fan blades are installed on the output shaft of the motor.

The aforementioned internal cooling device for an electron accelerator is characterized in that: the fan blades are installed in a wind deflector cover, and a mesh cover is installed on the wind deflector cover.

The aforementioned internal cooling device for an electron accelerator is characterized in that: the surface cooler is a ring structure, which is wound by a plurality of copper tubes with fins, and the water inlets and outlets of the copper tubes are welded in pairs , and leads to the water inlet and outlet.

The aforementioned internal cooling device for an electron accelerator is characterized in that the fan blades are welded or cast aluminum alloy.

The aforementioned internal cooling device for an electron accelerator is characterized in that the number of the motors is four, which are distributed at the four corners between the upper base plate and the lower base plate.

The beneficial effects of the present invention are: when the motor is turned on to drive the fan blades to rotate, since the upper and lower surfaces of the surface cooler are sealed by the upper and lower bottom plates, the fan blades force the airflow to be sucked in from the tubes of the surface cooler, and then the air flow from the guide air The cover is blown out, because all the airflow is inhaled from between the tubes of the surface cooler, and fully contacts the fins on the tubes of the surface cooler, so the cooling efficiency is high, and because the airflow is guided by the shroud when the wind blows out, the airflows will not interfere with each other. It will not cause mixed flow, and the cooling air can be more directly applied to the large heating elements inside the electron accelerator, which can better cool down the internal components of the electron accelerator, thereby ensuring the normal operation of the electron accelerator.

Description of drawings

Fig. 1 is a schematic structural view of an electron accelerator internal cooling device of the present invention.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, an electron accelerator internal cooling device includes an accelerator housing 10, an upper base plate 1 and a lower base plate 4 are arranged inside the accelerator housing 10, a surface cooler 2 is arranged between the upper and lower base plates, and the The surface cooler 2 is provided with a plurality of motors 3 , and fan blades 5 are installed on the output shafts of the motors 3 .

When the motor 3 is turned on to drive the fan blade 5 to rotate, since the upper and lower surfaces of the surface cooler 2 are sealed by the upper and lower bottom plates, the fan blade 5 forcibly sucks the airflow from the tubes of the surface cooler 2, and then blows it out from the air guide hood , because all the airflow is sucked from between the tubes of the surface cooler and fully contacts the fins on the tubes of the surface cooler, so the cooling efficiency is high.

Described fan blade 5 is installed in the deflector wind cover 6, and net cover 7 is installed on the deflector wind cover 6, has deflector cover 6 as guide when wind blows out, and each air flow can not interfere with each other, can not cause The mixed flow can more directly apply the cooling air to the large heating elements inside the electron accelerator, and better cool down the internal components of the electron accelerator, thus ensuring the normal operation of the electron accelerator.

In this embodiment, there are four motors 3, which are distributed at the four corners between the upper base plate 1 and the lower base plate 4, to further ensure the uniformity and cooling effect of the cooling air flow.

The surface cooler 2 is a ring structure, which is formed by winding a plurality of finned copper tubes, and the water inlet and the water outlet of the copper tubes are welded in pairs, and the water inlet and outlet pipes 9 are drawn out. This structure can be relatively The larger diameter of the copper pipe increases the flow rate of the cooling water flow and increases the cooling efficiency of the surface cooler 2 .

The fan blade 5 is made of aluminum alloy welding or casting. Due to the forced suction cooling, the fan blade 5 bears considerable pressure, and the inside of the accelerator is a high-pressure environment, so the fan blade 5 is a welded aluminum alloy structure. or cast structures.

To sum up, the internal cooling device of the electron accelerator provided by the present invention can greatly improve the cooling efficiency inside the electron accelerator, reduce energy consumption, and ensure the operation quality of the electron accelerator.
