Air coolers, cooling system comprising air coolers and temperature regulating and balancing method for CT (Computed Tomography) scanning machine

Abstract

The invention relates to air coolers, a cooling system comprising the air coolers and a temperature regulating and balancing method for a CT (Computed Tomography) scanning machine. A plurality of negative pressure fans are arranged on the back side of a condenser of each air cooler in an array form; a condensation water tank is also arranged below the condenser; a water pump is arranged in the condensation water tank; a porous spraying pipe is arranged at the upper end of the condenser and is connected with the water pump through a pipeline; the cooling system comprises a CT scanning machine, two parallel air coolers, a receiving controller, a transmitting processor, a bulb tube temperature sensor, a condenser temperature sensor, a detector temperature sensor and a displacement sensor; a cold air outlet of the auxiliary air cooler is connected into the main air cooler through a connector and is connected with a cold air outlet of the main air cooler in parallel; the cold air outlet of the auxiliary air cooler and the cold air outlet of the main air cooler are jointly communicated with an air inlet of a rack through a cold air pipeline. According to the invention, no condensation water is stored in the air coolers, so that the energy efficiency of refrigeration is improved; the cooling system directly refrigerates a CT scanning rack, so that air temperatures of the CT bulb tube and a detector assembly in the scanning rack are reduced.

Description

technical field [0001] The invention belongs to the technical field of directional refrigeration for local heat sources in an air-conditioned environment, and relates to a cooling fan and its cooling system, as well as a method for temperature adjustment and equalization of a CT scanning machine, mainly to the technical field of heat dissipation of CT tubes, in particular to high-power CT The equivalent heat capacity of the ball tube is improved and the service life is extended. Background technique [0002] A CT scanning machine mainly includes a frame, a CT tube and a detector assembly arranged in the frame, wherein the CT tube is an X-ray source of CT and is a high-value consumable part. The tube core of the CT tube is mainly composed of a filament, a rotating target disk and a vacuum chamber. The filament is heated to generate thermal electrons, which bombard the heavy metal target disk under the action of a high-voltage DC electric field to generate X-rays. When the...
