Description

Technical Field

[0001] The utility model relates to the technical field of CBCT equipment, in particular to a CBCT radiation source oil tank heat dissipation device and a CBCT. Background Art

[0002] CBCT is a cone-beam computed tomography (CBCT) device. Its principle is that the X-ray generator performs circular digital projection around the projection object with a low dose of radiation, and then reconstructs the data obtained from the intersection of multiple digital projections around the projection object in a computer to obtain a three-dimensional image.

[0003] The radiation source tank in a CBCT generates a significant amount of heat during operation. Failure to dissipate this heat in a timely manner will affect the tank's performance and, in severe cases, damage it. Currently, some CBCT devices on the market lack heat dissipation, resulting in extended cooling time after each scan, causing significant inconvenience for customers. While some do have heat dissipation devices, these devices suffer from low heat dissipation efficiency, preventing continuous scanning. Furthermore, most devices equipped with heat dissipation devices require heat-collecting plates, which are relatively expensive. Therefore, a low-cost, high-efficiency heat dissipation device is needed to dissipate heat from CBCT devices. Utility Model Content

[0004] The utility model provides a CBCT radiation source oil tank heat dissipation device and a CBCT, which can effectively improve the heat dissipation efficiency; at the same time, the combination of a fan and an air duct is adopted, which is different from the traditional method of setting a heat collection plate, and has the advantages of simple structure and low cost.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A CBCT radiation source oil tank heat dissipation device includes a base and an oil tank mounted on the base, an air duct assembly disposed along at least one side of the oil tank to form a heat dissipation channel, a heat sink disposed between the oil tank side and the air duct assembly, and a fan assembly disposed at an end of the air duct assembly to generate unidirectional heat dissipation air along the heat dissipation channel.

[0007] Preferably, the air duct assembly is arranged along three adjacent sides of the oil tank.

[0008] Preferably, the base includes a bottom plate, a vertical plate fixedly arranged on the top of the bottom plate, and a support plate arranged on the top of the vertical plate.

[0009] Preferably, the CBCT source oil tank heat dissipation device further includes a wind shield provided on the air duct assembly for isolating the upper and lower airflows of the oil tank.

[0010] Preferably, the air duct assembly includes a lee duct arranged on the back side of the fuel tank for guiding air, and side ducts arranged on two opposite sides of the fuel tank for guiding air.

[0011] Preferably, the lee duct includes a U-shaped base plate and a back plate arranged parallel to the base of the U-shaped base plate to form a strip-shaped channel.

[0012] Preferably, a plurality of partitions for separating the strip-shaped channels are provided between the U-shaped base plate and the inner wall of the back plate.

[0013] Preferably, the side air duct includes a plurality of side plates arranged along the side of the U-shaped base plate to form a tapered channel and a delivery channel connected to the top of the tapered channel and located on the side of the oil tank.

[0014] Preferably, the fan assembly includes a blowing fan arranged at the air inlet end of the side air duct and a suction fan arranged at the air outlet ends of the side air duct and the lee air duct.

[0015] Preferably, the fan assembly further comprises a fan mounting plate provided on the oil tank for mounting the suction fan, and a rubber strip is provided on the top of the fan mounting plate.

[0016] Preferably, the CBCT source oil tank heat dissipation device further includes a control board mounting plate arranged on the oil tank and a fan control board arranged on the control board mounting plate.

[0017] A CBCT comprises the aforementioned CBCT radiation source oil tank heat dissipation device.

[0018] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0019] 1. In the utility model, the heat generated by the radiation source oil tank when it is working is directly absorbed by the heat sink. When the fan assembly is working, the heat absorbed by the heat sink flows unidirectionally through the air duct assembly, taking away the heat generated by the radiation source oil tank when it is working, forming a circulation of hot and cold air, and ensuring that the radiation source oil tank can work normally. By arranging structures for heat dissipation on multiple outer sides of the radiation source oil tank, and the heat sink is in direct contact with the radiation source oil tank, the heat dissipation efficiency can be effectively improved. At the same time, the combination of the fan and the air duct is different from the traditional method of arranging a heat collection plate, and has the advantages of simple structure and low cost.

[0020] 2. In the present invention, the air duct assembly includes a leeward duct and a side air duct. The leeward duct includes a U-shaped base plate and a back plate that cooperates with the U-shaped base plate to form a strip-shaped channel. The side air duct includes a side plate for forming a tapered channel and a conveying channel connected to the tapered channel. In this way, a chimney-type air duct design is adopted to ensure that heat does not convect with each other and the heat exchange efficiency is high.

[0021] 3. In the present invention, the fan assembly includes a blowing fan and a suction fan. The blowing fan can bring air into the side duct and the lee duct. At the same time, the suction fan sucks air from the top of the side duct and the lee duct above, so that the wind pressure at the upper end is small, the hot air goes upward, and the air with lowered temperature is sucked in by the way, forming a circulation of hot and cold air to ensure the normal operation of the radiation source oil tank.

[0022] 4. In the present invention, the wind shield is arranged on the air duct assembly and is located at the bottom position of the front side of the radiation source oil tank. The wind shield can relatively isolate the hot air above and the cold air below, so that convection is not formed between the two airs, thereby ensuring the hot and cold circulation and increasing the heat dissipation efficiency.

DETAILED DESCRIPTION

[0032] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] In order to achieve the above purpose, the embodiment of the present utility model adopts the following technical solutions: Figure 1、 Figure 2 、 Figure 3 、 Figure 4 The CBCT radiation source oil tank heat dissipation device includes a base 10 and an oil tank 20. The oil tank 20 is arranged on the base. Further, the heat dissipation device also includes an air duct assembly, a heat sink 80 and a fan assembly. The air duct assembly is arranged along at least one side of the oil tank to form a heat dissipation channel on the side of the oil tank. The heat sink is arranged between the side of the oil tank and the air duct assembly. The fan assembly is arranged at the end of the air duct assembly to form a unidirectional heat dissipation wind along the heat dissipation channel. In this embodiment, the air duct assembly is distributed along three adjacent sides of the oil tank, that is, the number of the air duct assembly is 3, and the 3 air duct assemblies are divided into 4 parts along the oil tank. There is one distributed on the back and two symmetrically arranged on the opposite sides of the oil tank. In this way, when in use, the heat generated by the radiation source oil tank when it is working is directly absorbed by the heat sink. When the fan assembly is working, the heat absorbed by the heat sink flows unidirectionally through the air duct assembly, taking away the heat generated by the radiation source oil tank when it is working, forming a circulation of hot and cold air, and ensuring that the radiation source oil tank can work normally. Since structures for heat dissipation are arranged on multiple outer sides of the radiation source oil tank, the heat dissipation efficiency can be effectively improved. At the same time, the combination of fan and air duct is different from the traditional method of setting up a heat collection plate, and has the advantage of low cost.

[0034] It should be noted that the heat sink corresponds to the air duct assembly, that is, in this embodiment, there are three heat sinks corresponding to the number and position of the air duct assembly. When in use, thermal grease is evenly applied to the side wall of the oil tank, and the heat sink is connected to the source oil tank through a pressure cover.

[0035] Reference Figure 6 Furthermore, the base 10 includes a bottom plate 110, a vertical plate 120 and a support plate 130. The vertical plate 120 is fixed on the top of the bottom plate, and the support plate 130 is fixed on the top of the side plate. In this way, the base forms a main support structure through the bottom plate, the vertical plate and the support plate, thereby facilitating the installation of the radiation source tank and other components.

[0036] Reference Figure 1 As a preferred technical solution of this embodiment, the CBCT source oil tank heat dissipation device further includes a wind shield 50 provided on the air duct assembly for isolating the upper and lower airflows of the oil tank. The wind shield is located at the bottom of the front of the source oil tank. The wind shield can relatively isolate the hot air above and the cold air below, preventing convection between the two air, thereby ensuring hot and cold circulation and increasing heat dissipation efficiency.

[0037] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7As a preferred technical solution of this embodiment, when there are three air duct assemblies, the air duct assembly specifically includes a leeward duct 310 and a side duct 320. The leeward duct 310 is provided on the back side of the fuel tank for guiding air on the back side of the fuel tank. Similarly, the side ducts 320 are provided on two opposite sides of the fuel tank for guiding air on two opposite sides of the fuel tank.

[0038] Reference Figure 8 Furthermore, the lee duct 310 includes a U-shaped base plate 311 and a back plate 312. It should be noted that the U-shaped base plate is arranged on the top of the base 10, and the U-shaped base plate includes a base and side portions arranged on both sides of the base. The back plate 312 is arranged parallel to the base of the U-shaped base plate. The back plate 312 and the U-shaped base plate 311 are combined to form a strip channel. The strip channel is placed on the back side of the fuel tank to facilitate air intake from the back side of the fuel tank.

[0039] In addition, a plurality of partitions 313 are provided between the U-shaped base plate 311 and the inner wall of the back plate 312. The partitions 313 are used to separate the strip channel into a plurality of independent sub-air ducts, so that independent airflows are formed in the strip channel when air enters.

[0040] Furthermore, the side air duct 320 includes a plurality of side panels 321, and the plurality of side panels 321 are arranged along the side of the U-shaped base plate 311. It should be noted that the plurality of side panels are based on the side outer wall of the U-shaped base plate, and the plurality of side panels together with the side wall of the U-shaped base plate are fitted together to form a conical channel. The delivery channel 322 is connected and arranged at the top of the conical channel, and the delivery channel is located on two opposite sides of the oil tank. When in use, air enters from the bottom of the conical channel. Under the action of the fan assembly, the wind is transported upward through the conical channel and the delivery channel in turn, thereby transporting the heat absorbed by the heat sink to achieve a hot and cold cycle.

[0041] It should be noted that the conical channel formed by the side air duct is connected to the bottom end of the strip channel formed by the leeward duct, so that when the air is introduced through the conical channel and the strip channel, the side air duct and the leeward duct can be introduced synchronously. However, after the air introduction is completed, since the channels are independent of each other and do not interfere with each other, each air duct can work independently.

[0042] Reference Figure 5Furthermore, the fan assembly includes a blowing fan 410 and a suction fan 420. The blowing fan 410 is arranged at the air inlet end of the side air duct for blowing air into the side air duct, and the suction fan 420 is arranged at the air outlet end of the side air duct and the lee air duct. Specifically in this embodiment, since the number of side air ducts is 2 and the number of lee air ducts is 1, the corresponding number of blowing fans is 2, and the blowing fans are arranged at the bottom of the conical channel; the number of suction fans is 3, of which 2 suction fans are arranged on both sides and above the conveying channel, and 1 suction fan is located in the middle and above the strip channel. In this way, the upper and lower side fans work at the same time, so that the wind pressure at the upper end is small, the hot air goes upward, and at the same time the air with lowered temperature can be sucked in to form a circulation of hot and cold air to ensure that the source oil tank can work normally.

[0043] As a preferred technical solution of this embodiment, the fan assembly also includes a fan mounting plate 430 arranged on the oil tank 20 for installing the suction fan 420. A rubber strip 440 is provided on the top of the fan mounting plate. The fan mounting plate is used to install the aforementioned suction fan. Specifically, the fan mounting plate can be a frame structure to facilitate the installation of the fan.

[0044] As a preferred technical solution of this embodiment, the CBCT source oil tank heat dissipation device further includes a control panel mounting plate 60 disposed on the oil tank 20 and a fan control panel 70 disposed on the control panel mounting plate. The fan control panel is electrically connected to the aforementioned blower and suction fans to control the operation of the fans.

[0045] The present invention also provides a CBCT including the aforementioned CBCT radiation source oil tank heat dissipation device. In this way, under the action of the fan assembly, the air duct assembly disposed outside the radiation source oil tank can be used to discharge heat generated during operation of the oil tank, thereby achieving circulation of hot and cold air to ensure the normal operation of the radiation source oil tank.

[0046] When in use, first connect the radiation source oil tank and the base, then connect the heat sink to the radiation source oil tank through the pressure cover, the lee duct is arranged as a whole on the top of the base, the side ducts are arranged at both ends of the lee duct, and the blowing fans on both sides are installed on the side ducts, the fan control board is installed on the fan control board mounting plate and then installed on the radiation source oil tank, and finally the suction fan is installed side by side on the fan mounting plate. The heat generated when the radiation source oil tank is working is directly absorbed by the heat sink, and the fan control board controls the operation of the blowing fan and the suction fan. Among them, the heat absorbed by the heat sinks on the left and right sides is blown upward through the blowing fans on the left and right sides and their respective conveying channels, and then the heat absorbed by the back heat sink is blown upward through the left and right The side blowers and strip channels blow upwards, and the wind directions of the channels do not interfere with each other. The blowers on the left and right sides blow upwards, and the three suction fans above suck air. The three middle suction fans above are responsible for absorbing the heat from the back heat sink, and the left and right suction fans are used to absorb the heat from the heat sinks on the left and right sides. This reduces the wind pressure at the upper end and allows the hot air to move upwards. By the way, the air with lowered temperature can be sucked in by the fan to form a circulation of hot and cold air, ensuring the normal operation of the source tank. At the same time, the presence of the wind shield can relatively isolate the hot air above and the cold air below, so that no convection is formed between the two. This ensures the circulation of hot and cold air and increases the heat dissipation efficiency.

[0047] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
