Description

Technical Field

[0001] The utility model relates to the technical field of X-ray tube cores, in particular to a cooling system applied to X-ray tube cores. Background Art

[0002] The X-ray tube core is the main core component of the CT machine. The X-ray tube core is a vacuum diode working under high voltage.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-4 As shown, the utility model provides a cooling system for an X-ray tube core, comprising a heat conducting block 10 , a first conveying tube body 11 , a second conveying tube body 12 , a third conveying tube body 13 , an oil storage tank 14 and a circulating pump 15 .

[0020] The heat conducting block 10 is made of heat conducting material and is disposed in the ray window of the X-ray tube core 20. It should be understood that since the heat conducting block 10 is made of heat conducting material, the heat at the ray window of the X-ray tube core 20 can be transferred to the heat conducting block 10.

[0021] Preferably, the heat conducting block 10 is in a rectangular three-dimensional shape, wherein a surface of the heat conducting block 10 connected to the X-ray tube core 20 is in an arc shape, and the heat conducting block 10 and the X-ray tube core 20 are integrally formed.

[0022] In this embodiment, the heat conducting block 10 is provided with a ray hole 101 corresponding to the ray window, so that the X-rays generated by the X-ray tube core 20 pass through the ray window and the ray hole 101 .

[0023] Preferably, the shape and size of the ray window and the ray hole 101 are the same, wherein both ends of the coolant pipe 102 are arranged at one end of the heat conducting block 10 .

[0024] Furthermore, a coolant tube 102 surrounding the ray hole 101 is provided in the heat conductive block 10, and both ends of the coolant tube 102 are exposed outside the heat conductive block 10. It should be understood that the coolant tube 102 is used to transport the coolant, so the heat of the heat conductive block 10 can be transferred to the coolant in the coolant tube 102 to take away the heat, and the ray window of the X-ray tube core 20 has a good heat dissipation effect.

[0025] One end of the first delivery pipe body 11 is connected to one end of the coolant pipe 102 for receiving the coolant output by the coolant pipe 102 .

[0026] The oil storage tank 14 is used to store coolant, wherein an input port of the oil storage tank 14 is connected to the other end of the first delivery pipe body 11 for receiving the coolant delivered by the first delivery pipe body 11 .

[0027] One end of the second delivery pipe body 12 is connected to the output port of the oil storage tank 14 , and the other end of the second delivery pipe body 12 is connected to the input port of the circulation pump 15 , so that the coolant in the oil storage tank 14 is delivered to the second delivery pipe body 12 .

[0028] One end of the third delivery pipe body 13 is connected to the output port of the circulation pump 15 , and the other end of the third delivery pipe body 13 is connected to the other end of the coolant pipe 102 , so that the coolant in the oil storage tank 14 is pumped into the coolant pipe 102 through the circulation pump 15 .

[0029] Preferably, a heat exchanger is provided in the oil storage tank 14 so that the heat of the coolant in the oil storage tank 14 can be exchanged by the heat exchanger, so that the coolant with a relatively low temperature can be pumped back to the heat conducting block 10 for heat exchange.

[0030] In this embodiment, a receiving cavity is provided in the oil storage tank 14 , wherein a separation plate 140 is provided in the receiving cavity, and the separation plate 140 divides the receiving cavity into a first receiving cavity 141 and a second receiving cavity 142 .

[0031] Preferably, the receiving cavity is rectangular, and the isolation plate 140 is rectangular, wherein the height of the isolation plate 140 is smaller than the depth of the receiving cavity, so that the tops of the first receiving cavity 141 and the second receiving cavity 142 are connected.

[0032] Furthermore, the other end of the first delivery tube body 11 passes through the input port of the oil storage tank 14 and is connected to the first receiving cavity 141, so that the coolant delivered by the first delivery tube body 11 is delivered to the first receiving cavity 141, and one end of the second delivery tube body 12 is connected to the second receiving cavity 142, so that the coolant in the second receiving cavity 142 is delivered to the second delivery tube body 12, and the top end of the first receiving cavity 141 is connected to the top end of the second receiving cavity 142, and the heat exchange element is arranged in the first receiving cavity 141.

[0033] It should be understood that the coolant output from the heat conductive block 10 is transported to the first receiving cavity 141 through the first delivery pipe body 11, and the coolant in the first receiving cavity 141 slowly rises after exchanging heat with the heat exchange element, and then flows from the top of the first receiving cavity 141 to the second receiving cavity 142, and finally the relatively low-temperature coolant in the second receiving cavity 142 is pumped back to the heat conductive block 10 by the circulating pump 15 for heat exchange, and circulated in sequence.

In other words, the condensed water flows in from one end of the heat exchange tube 143, enters the first receiving cavity 141, exchanges heat with the coolant in the first receiving cavity 141, and is then output from the other end of the heat exchange tube 143.

[0035] Preferably, the heat exchange tube 143 received in the first receiving cavity 141 is spirally shaped, so that the condensed water in the heat exchange tube 143 and the coolant in the first receiving cavity 141 have enough time to exchange heat, the heat exchange area is also increased, and the heat exchange effect is better.

[0036] Furthermore, in other embodiments, the cooling system applied to the X-ray tube core also includes a fourth transport tube body made of a heat-conductive material, wherein the fourth transport tube body is arranged on the outer wall of the X-ray tube core 20 for heat exchange, one end of the fourth transport tube body is connected to one end of the first transport tube body 11, and the other end of the fourth transport tube body is connected to the other end of the third transport tube body, so that the coolant transported by the third transport tube body 13 can enter the fourth transport tube body, so as to perform heat exchange on the outer wall of the X-ray tube core 20 through the coolant of the fourth transport tube body, which can effectively improve the life of the X-ray tube core 20.

[0037] Preferably, a switch valve for controlling the on-off of the fourth conveying pipe body is also provided in the fourth conveying pipe body.

[0038] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
