Integrated high-speed rotating cooling machine

Abstract

The invention belongs to the field of high-speed rotating cooling machines, and particularly relates to an integrated high-speed rotating cooling machine. The integrated high-speed rotating cooling machine comprises a housing body, a housing cover and a rotating shaft, wherein the housing cover and the cylinder wall of a large-caliber section of the housing body are enclosed to form an accommodating space for accommodating a rotating target film assembly; the rotating target film assembly comprises a rotating cavity and a target film; the rotating cavity is coaxially sleeved with the housing body and is provided with a small-diameter section; the small-diameter section is sleeved with an air bearing, so that the small-diameter section and a small-caliber section form a coaxial rotary fit; the rotating shaft is in a coaxial rotary fit on the housing cover through a rolling bearing in a manner of a simply supported beam; a shaft end of the rotating shaft extends towards a target surface of the target film along the axis of the target film and the shaft end of the rotating shaft and the target surface of the target film form a fixed connection fit; and the diameter of the rotating shaft is smaller than the outer diameter of the small-diameter section of the rotating cavity. The integrated high-speed rotating cooling machine has performance advantages of a large-shaft diameter cooling machine and a high-rotating speed cooling machine, can achieve the high-speed rotating target and can bear certain radial force and axial force.

Description

technical field [0001] The invention belongs to the field of high-speed rotary coolers, in particular to an integrated high-speed rotary cooler. Background technique [0002] The high-speed rotary cooler is used in the neutron generator and is the key equipment of the neutron generator. Its performance directly determines the neutron strength and stability of the neutron generator. When the deuterium ion beam is accelerated and transmitted to the tritium target in the high-speed rotary cooler, and undergoes a deuterium-tritium fusion reaction with the tritium nucleus in the target to generate neutrons, the neutrons produced can be used for neutron cancer treatment, etc. in a specific industry. Since the deuterium-tritium fusion reaction at the target will bring huge heat, the current expectation is to use a cooler with a large shaft diameter and high rotation speed, so as to increase the number of heat exchanges in the same time, thereby ensuring the heat dissipation of the...

Problems solved by technology

However, the currently used large-diameter coolers are limited by the size and volume of the speed-up box, the force is more complicated, and the stability is poor, so it is very unsuitable for fine neutron generation operations.

However, the shaft diameter of the traditional high-speed cooling machine is relatively small. Once it is applied to the above-mentioned fields, it will lead to narrowing of the deuterium ion beam channel, thereby making the utilization rate of the target plate relatively low.
