Cooling assembly of medical device and medical device

Abstract

The invention discloses a medical device and a cooling assembly of the medical device. The medical device comprises a frame, a housing, a fluid containing portion, a fluid pipe, a pump and a cooling source. The frame is connected with a heat generating member. The housing includes a fluid containing portion defining an inlet and an outlet. Two ends of the fluid pipe are respectively in communication with the inlet and the outlet, the fluid pipe passes the heat generating member in a heat transmission mode. The pump is connected to the fluid pipe to make the fluid in the fluid containing portion circulate in the fluid pipe. The cooling source is configured to relate to the housing to make heat of at least one portion of the housing transmit to the cooling source. According to the cooling assembly and the medical device having the cooling assembly disclosed by the invention, pipes does not need connecting to a cooling source, such as a water source, at someplace on the ground.

Description

technical field [0001] The invention relates to a medical device, in particular to a cooling assembly for the medical device. Background technique [0002] At present, in medical linear accelerators, many high-power components, such as accelerating tubes and modulators, require water cooling to ensure the normal operation of the system. For linacs with a rotating gantry, cooling water is piped to the various components. After the cooling water takes the heat out of each component, a heat exchange system needs to be configured to exchange heat. The current design of the heat exchange system is limited by its own factors and can only be installed outside the rotating frame, which will result in the need for water pipes to be connected from the heat exchange system to various components, passing through winding racks, racks, etc. This design will cause the water pipe to rotate with the winding frame and frame, which not only increases the length and cost of the water pipe, bu...

Problems solved by technology

The current design of the heat exchange system is limited by its own factors and can only be installed outside the rotating frame, which will result in the need for water pipes to be connected from the heat exchange system to various components, via winding frames, frames, etc.

This design will cause the water pipe to rotate with the winding frame and frame, which not only increases the length and cost of the water pipe, but also puts forward additional requirements for the water pipe’s fatigue life, which increases the complexity of the system
