DETAILED DESCRIPTION
[0030] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.
[0031] One aspect of the present application provides a cooling structure, and another aspect provides an X-ray source device having the cooling structure. It can be understood that although the cooling structure applied in the X-ray source device will be mainly taken as an example for the description of structure and principle in the subsequent description, the cooling structure provided by the present application can also be applied to other occasions, for improving the use flexibility of the electrical device by reducing the volume of the electrical device while meeting the heat dissipation requirements of the electrical device.
[0032] As shown in Figure 1 The first aspect of the present application provides a cooling structure for an electrical device, which comprises a housing 100, a partition 400 and a pipeline 200. The housing 100 is used to enclose an accommodating space 110. The partition 400 is arranged in the accommodating space 110 and can divide the accommodating space 110 into a plurality of receiving spaces. The plurality of receiving spaces are used to correspondingly receive a plurality of components of the electrical device. The pipeline 200 is arranged in the housing 100. The pipeline 200 has an inlet 210 and an outlet 220 for cooling medium to flow into and out of the pipeline 200. The pipeline 200 is arranged to be able to communicate with at least one of the receiving spaces.
[0033] According to the cooling structure provided by the utility model, the inlet 210 is used for flowing cooling medium into the pipeline 200. The outlet 220 is used for flowing cooling medium out of the pipeline 200. In the process of flowing cooling medium through the pipeline 200, the heat generated by the components of the electrical equipment in the accommodation space 110 during the working process can be taken away, and the normal working of the components of the electrical equipment is not affected by the heat accumulation. Compared with the prior art, the cooling structure provided by the utility model does not need to additionally set a cooling device in the electrical equipment to achieve cooling, thereby effectively reducing the volume of the electrical equipment and improving the flexibility of the electrical equipment.
[0034] In particular, in the technical scheme provided by the utility model, the accommodation space 110 is divided into a plurality of accommodation spaces by the partition plate 400 to accommodate a plurality of components of the electrical equipment, and the pipeline 200 is arranged to be capable of communicating with at least one of the accommodation spaces. Through the above arrangement, the plurality of components of the electrical equipment can be conveniently classified and arranged, for example, the components with large heat dissipation capacity are placed in the accommodation space which is easy to cool and heat dissipate, and the pipeline 200 is connected to the accommodation space to enable the cooling medium to directly contact the components with large heat dissipation capacity, thereby improving the cooling and heat dissipation efficiency of the components with large heat dissipation capacity.
[0035] When the cooling structure provided by the utility model is used, the inlet 210 of the pipeline 200 is connected to the cooling medium outlet of the external cooling device to continuously introduce the cooling medium into the pipeline 200. For example, when cold air is used as the cooling medium, the inlet 210 of the pipeline 200 is connected to the cold air outlet of the external air cooling device, or directly connected to the air cooling device of the use device of the electrical equipment.
[0036] It can be understood that the shell 100 can be the shell structure of the electrical equipment.
[0037] According to the cooling structure provided by the utility model, the concept of the utility model is to integrate the pipeline 200 for heat exchange into the shell 100, use the cooling device of the external device to provide cooling medium for the pipeline 200, and cool the components in the shell 100 and the accommodation space 110 formed by the shell 100, thereby meeting the cooling and heat dissipation requirements, reducing the volume of the electrical equipment, and improving the flexibility of the electrical equipment. In addition, the accommodation space 110 is divided by the partition plate 400 to independently accommodate the components with large heat dissipation capacity, and the pipeline 200 is connected to the accommodation space to enable the cooling medium to be introduced to directly contact the components with large heat dissipation capacity, thereby ensuring that the plurality of components of the electrical equipment can be effectively cooled and heat dissipated at a low cost, ensuring that the components of the electrical equipment can work normally and avoiding the problem that the components of the electrical equipment cannot work normally due to heat accumulation.
[0038] It should be noted that, in the utility model, the pipeline 200 is arranged in the shell 100, and it can be understood that the pipeline 200 is arranged in the thickness range of the shell 100 by means of embedding or integrated forming, or the pipeline 200 is directly laid on the inner side or the outer side surface of the accommodating space 110 enclosed by the shell 100, as long as the heat generated by the components in the accommodating space 110 during operation can be timely removed when the cooling medium is passed, the heat dissipation cooling effect is met, and the volume of the electric equipment itself is reduced.
[0039] In the utility model, the pipeline 200 can be arranged in the shell 100 in any appropriate form, for example, the pipeline 200 is arranged in a folded manner on one side of the accommodating space 110 enclosed by the shell 100.
[0040] Further, in the embodiment of the utility model, the pipeline 200 further includes an outlet pipe section 203 arranged on the first side 111 of the shell 100, and the plurality of dispersion pipe sections 202 are respectively communicated with the outlet pipe section 203, so as to lead the cooling medium out of the first side 111.
[0041] It should be noted that, in the technical scheme provided by the utility model, due to cost considerations or actual structure limitations, the pipeline 200 will not be arranged on each side of the shell 100, and the inlet pipe section 201, the dispersion pipe section 202 and the outlet pipe section 203 will not be arranged on each side at the same time. For example, in some embodiments, the shell 100 is connected to the door member in a detachable manner, so as to realize the opening and closing of the accommodating space 110, and on the side where the door member is arranged, the layout area of the pipeline 200 is limited.
[0042] In some embodiments, the pipeline 200 further comprises a flow pipe section 204 for guiding the cooling medium to a second side 112 of the shell 100 opposite to the first side 111. That is, the inlet pipe section 201, the dispersion pipe section 202 and the outlet pipe section 203 are arranged on the opposite first side 111 and second side 112 respectively, and are connected by the flow pipe section 204. Through the above scheme, the heat dissipation requirement of the electrical equipment is met, and cost control is realized.
[0043] Referring to Figure 1 In the illustrated embodiment, the inlet pipe section 201 and the outlet pipe section 203 extend along the length direction of the shell 100, and are spaced apart along the height direction of the shell 100. The dispersion pipe section 202 extends along the height direction of the shell 100 between the inlet pipe section 201 and the outlet pipe section 203, and a plurality of dispersion pipe sections 202 are spaced apart along the length direction of the shell 100.
[0044] Referring to Figure 1 The first side 111 and the second side 112 are oppositely arranged. On the first side 111, the inlet pipe section 201 is located above the outlet pipe section 203. On the second side 112, the inlet pipe section 201 is located below the outlet pipe section 203.
[0045] In other embodiments not shown in the utility model, the first side and the second side can also be in an adjacent relationship.
[0046] In some embodiments, the dispersion pipe section 202 is configured in a wave shape. Through the above arrangement, the length of the pipeline 200 and the layout area of the pipeline 200 in the shell 100 are increased, and the heat dissipation efficiency is improved.
[0047] In some embodiments, the inner wall of the pipeline 200 is configured as a smooth surface. Through the above arrangement, the flow resistance of the cooling medium in the pipeline 200 is reduced, and the heat dissipation efficiency is improved.
[0048] In some embodiments, the inlet 210 and the outlet 220 are respectively provided with a connecting joint 300 for establishing the connection between the pipeline 200 and an external pipeline.
[0049] The cooling medium can be commonly used in the field, for example, can be air or insulating oil, the temperature of the cooling medium is reduced by using external equipment, and then is introduced into the pipeline 200 through the inlet 210, and after absorbing the heat of the components in the accommodating space 110 enclosed by the shell 100, is led out through the outlet 220. It can be understood that, in order to reduce the cost, the cooling medium is also returned to the external equipment to be cooled again, and is returned to the pipeline 200 again, and the components in the accommodating space 110 enclosed by the shell 100 are cooled by the circulating mode.
[0050] In combination Figure 2 The utility model discloses a kind of X-ray source devices, the X-ray source device has the cooling structure described above, and the multiple components of the X-ray source device are dispersedly arranged in multiple said accommodating spaces.
[0051] In prior art, when X-ray source device is used, the heat generated by each component thereof is very large, to meet the cooling device used for heat dissipation effect will occupy a part of space, resulting in the volume of the whole X-ray source device is large, and the use flexibility is poor. After using the cooling structure provided by the utility model, cooling device does not have to be additionally arranged in X-ray source device, and cooling equipment can be directly connected, or directly connected to the cooling device of using equipment itself, with good cooling effect, while effectively reducing the volume of X-ray source device, making the use flexibility stronger.
[0052] In combination Figure 3 、 Figure 4 And Figure 5 As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, in some embodiments, the accommodating space includes a control cavity 1101 located at the lower layer, a transformer mounting cavity 1102 and an oil tank cavity 1103 located at the upper layer and arranged in sequence along the front-rear direction. The circuit board is installed in the control cavity 1101, the transformer and the inductor are installed in the transformer mounting cavity 1102, and the X-ray tube and the high-voltage circuit packaging module are installed in the oil tank cavity 1103. The oil tank cavity 1103 is a sealed cavity, and is filled with insulating oil.
[0053] Further, a wiring cavity 1104 is also arranged side by side beside the transformer mounting cavity 1102, the wiring cavity 1104 is connected with the control cavity 1101 at the lower layer and the transformer mounting cavity 1102 at the side through the wire hole, and an electric switching plate capable of sealing the oil tank cavity 1103 is arranged at the side close to the oil tank cavity 1103.
[0054] In the utility model, the insulating oil in the oil tank cavity 1103 plays the role of insulation on one hand, and can uniformly transmit the heat generated by the X-ray tube and the high-voltage circuit packaging module in working time to the shell 100, and then the heat is taken away by the cooling medium in the pipeline 200.
[0055] In the utility model, the pipeline 200 can be arranged in the shell 100 in any appropriate form, so that the heat generated by each component in the accommodation space 110 can be effectively taken away.
[0056] Reference Figures 2 to 5 In some embodiments, the shell 100 is arranged to form a front end wall 120 and a rear end wall 130 arranged in sequence along the front-rear direction (corresponding to the length direction of the shell in the figure), and a left side wall 140 and a right side wall 150 (corresponding to the two side surfaces in the left-right direction of the shell in the figure) arranged between the front end wall 120 and the rear end wall 130 and spaced apart. The pipeline 200 includes an inlet main pipe 230 and a plurality of inlet branch pipes 231 arranged in the left side wall 140, an outlet main pipe 240 and a plurality of outlet branch pipes 241 arranged in the right side wall 150, and a U-shaped manifold 250 arranged in the left side wall 140, the rear end wall 130 and the right side wall 150. A plurality of inlet branch pipes 231 are arranged along the front-rear direction of the left side wall 140 and can respectively communicate with the inlet main pipe 230 and the U-shaped manifold 250 (see Figure 3 ). A plurality of outlet branch pipes 241 are arranged along the front-rear direction of the right side wall 150 and can respectively communicate with the U-shaped manifold 250 and the outlet main pipe 240 (see Figure 5 ).
[0057] In specific use, the external cooling medium enters the inlet main pipe 230 through the inlet 210 and flows along the front-rear direction of the left side wall 140, is dispersed in the left side wall 140 through the plurality of inlet branch pipes 231, is then collected through the U-shaped manifold 250, is routed to the right side wall 150 through the U-shaped manifold 250, is dispersed in the right side wall 150 through the outlet branch pipes 241, and is finally collected through the outlet main pipe 240 and led out through the outlet 220.
[0058] It can be understood that the inlet main pipe 230 can be arranged at the top of the left side wall 140, and a plurality of inlet branch pipes 231 are respectively arranged in the left side wall 140 along the vertical direction, so that the U-shaped manifold 250 is correspondingly arranged at the bottom of the left side wall 140, the rear end wall 130 and the right side wall 150, and the control cavity 1101 located in the lower layer is cooled and radiated.
[0059] In some embodiments, the pipe 200 is in communication with the transformer installation cavity 1102 for the cooling medium to flow through the transformer installation cavity 1102 (see Figure 5 ). Specifically, the cooling medium enters the transformer installation cavity 1102 through the pipe 200 (a part), and then flows out from the pipe 200 (another part) after dissipating the heat of the transformer, inductor and the like in the transformer installation cavity 1102, thereby taking away the heat of the transformer, inductor and the like in the transformer installation cavity 1102.
[0060] In the X-ray source device provided by the utility model, the transformer and the inductor generate more heat than other components during work. By separately arranging the transformer and the inductor in the sealed transformer installation cavity 1102 and connecting the pipe 200 with the transformer installation cavity 1102, the cooling medium can directly flow through the cavity and directly contact the transformer and the inductor, thereby ensuring the heat dissipation effect.
[0061] It can be understood that, since the cooling medium directly enters the transformer installation cavity 1102, the transformer installation cavity 1102 needs to be sealed to prevent the cooling medium from leaking. After the related lines are connected, the wire hole needs to be plugged, for example, by filling and plugging with sealing glue.
[0062] The preferred embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited thereto. Within the technical concept of the utility model, the technical solution of the utility model can be subjected to various simple modifications. In order to avoid unnecessary repetition, the utility model will not further describe various possible combination modes. However, these simple modifications and combinations should also be regarded as the disclosed content of the utility model and belong to the protection scope of the utility model.
