Description

The invention relates to mechanical engineering and can be used in x-ray tube cooling systems.

A known cooling system containing a cylindrical tank filled with transformer oil to a level indicator, an oil pump, supplying and discharging oil pipelines with nozzles, an electric motor, a coil with drain and water nozzles, a thermal protection system (Technical description and operating instructions for a mobile x-ray industrial apparatus "RUP-150 / 300-10" of the Aktyubrentgen plant).

The disadvantages of this design are large dimensions, design complexity and high cost.

The technical result to which this invention is directed is the compactness of the x-ray tube cooling system with a three-chamber radiator, designed to maintain the optimum operating temperature of the x-ray tubes, reliable operation and low cost.

This technical result is achieved using a cooling system comprising a housing-casing of an X-ray tube, a coolant supply and discharge unit, a cooler inlet and drain unit, a cooler thermo-valve and a cooling unit, and according to the invention, the X-ray tube is cooled using a three-chamber radiator containing communicating input and an output chamber of a coolant and a passage chamber of a cooler, which are a collector-tubular communication system with two partitions separating the input chamber ru coolant, passage chamber of the cooler and the outlet chamber of the coolant.

In this case, in parallel with the circulation of the coolant, the cooler is circulated through the passage chamber of the three-chamber radiator.

The X-ray tube is cooled using a cooler through the coolant, the coolant circulates between the heat source and the cooling unit. The coolant (transformer oil) is cooled by a radiator, which is cooled by a cooler (water).

The invention is illustrated by drawings. In FIG. 1 shows a functional diagram of an X-ray tube cooling system with a three-chamber cooling system. In FIG. 2 shows a device of a three-chamber radiator of a cooling system.

The cooling system consists of a housing-casing of an X-ray tube 1, an inlet and outlet block for a cooler 2, a cooler 3, a three-chamber radiator 4, a heat valve for a cooler 5, a flow regulator for a heat carrier 6, a supply and drain unit for a heat carrier 7, and a heat carrier 8.

The design of the three-chamber cooling radiator consists of the inlet chamber of the coolant 9, a “G” -shaped inlet pipe of the cooler 10, a partition separating the inlet of the coolant and cooler 11, the pipes of the collector transit coolant 12, the passage chamber of the cooler 13, the partition separating the outlet of the coolant and cooler 14 A “G” -shaped outlet pipe of cooler 15, coolant outlet chamber 16, cooler inlet pipe 17, cooler outlet pipe 18, coolant inlet pipe 19, coolant outlet pipe 20.

The operation of the X-ray tube cooling system is to maintain operating temperatures from + 60 ° С to + 85 ° С (for different types and models of tubes) by circulating heat carrier 8 from the supply and discharge unit of heat carrier 7 to the casing of the x-ray tube 1, to the coolant inlet pipe 19 of a three-chamber radiator 4, the inlet chamber of the coolant 9, then through the pipes of the transit collector of the coolant 12 passing through the through-chamber of the cooler 13 into the outlet chamber of the coolant 16, the outlet of the coolant 20, the flow regulator 6 in the supply and discharge of the coolant 7.

In parallel with the circulation of the coolant 8 (above), the cooler 3 circulates from the intake and drain unit of the cooler 2, through the cooler thermal valve 5 to the cooler 17 inlet pipe of the three-chamber radiator 4, the “G” -shaped cooler inlet pipe 10, the cooler through passage 13, G "-shaped outlet pipe of the cooler 15, the outlet pipe of the cooler 18 in the inlet and outlet of the cooler 2.

Simultaneously with the cooling of the coolant 8, when passing through the collector tubes of the transit of the coolant 12 of the three-chamber radiator 4, additional cooling is carried out by a partition separating the inlet of the coolant and cooler 11, and a partition separating the output of the coolant and cooler 14, a “G” -shaped inlet pipe performs a similar function cooler 10 passing through the inlet chamber of the coolant 9, and "G" -shaped outlet pipe of the cooler 15 passing through the outlet chamber of the coolant 16.

This X-ray tube cooling system is used in industrial X-ray machines “RUP-150/300” and “XRS-320/26”, having proved itself reliable, compact and efficient in operation.
