It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention.
The utility model discloses a radiation protection box body system, include: the shielding box body is used for internally arranging electronic elements, isolating the internal gas from the external atmosphere and shielding rays emitted into the box body in the box body; the power source sucks the gas from the gas outlet of the shielding box body and sends the sucked gas into the shielding box body from the gas inlet of the shielding box body, so that the gas in the shielding box body circularly flows in a closed environment; and the refrigerating assembly is arranged between the shielding box body and the power source and used for cooling the gas sucked out of the shielding box body by the power source.
The utility model discloses a radiation protection box body system can realize the gaseous cooling that circulates in the airtight box and make humidity controllable, makes environment such as temperature, humidity in the airtight cavity satisfy box body electronic component's operational environment requirement.
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view showing a radiation-proof cassette system according to an embodiment of the present invention. The radiation-proof box system 100 of fig. 1 comprises a closed box 1, a refrigeration assembly 3 and a fan 5. The closed box body 1, the refrigerating assembly 3 and the fan 5 form a closed gas circulation loop, so that the internal gas cannot be exchanged with the external air.
The closed box body 1 is of an L-shaped structure. The closed box body 1 has a radiation protection requirement, and has a radiation protection function of preventing radiation incident to the inside from being radiated out. For example, a lead layer or the like may be provided on the outside of the case to prevent radiation from being emitted, and here, a radiation-proof material is not particularly limited as long as it is provided. In addition, the term "sealed" herein does not mean that the case itself is completely closed, but means that the gas inside the case cannot be exchanged with the air in the external atmosphere.
The sealed case 1 contains electronic components such as a detector, and can acquire information from the radiation incident inside. Because the detector is composed of electronic components, the requirements on the temperature and the humidity in the environment are high. It is necessary to operate at a proper temperature and humidity to ensure the accuracy and the service life of the electronic components. Therefore, in order to effectively control the temperature and the humidity in the working environment, the detector is installed in the closed box body, the gas in the box body is isolated from the external atmosphere, and the lower humidity is effectively kept. In addition, through setting up power supply and refrigeration subassembly for gaseous circulation refrigeration in inclosed environment can reduce the temperature in the box body.
Specifically, the fan 5 as a power source provides power for gas flow in a closed environment, and has a negative pressure end and a positive pressure end between which gas can circulate. The closed box 1 has an air outlet and an air inlet (not shown in the figure), which can be disposed at both ends of the closed box 1 in the length direction, as long as the air outlet and the air inlet are disposed at positions favorable for the flow of air in the box, and are not particularly limited. The negative pressure end of the fan 5 can suck out the gas in the closed box body 1 from the gas outlet and refrigerate through the refrigerating assembly 3. The positive pressure end of the fan 5 sends the refrigerated gas back to the closed box body 1 through the air inlet.
As the refrigerating assembly 3, for refrigerating the circulating gas in the closed space. Figure 2 is a partial cross-sectional view of a refrigeration assembly. The refrigeration assembly 3 includes a semiconductor refrigeration assembly 31, a heat sink 32, and a thermal insulating box 33. The heat sink 31 has fins and a base plate connected to the fins, for example, made of aluminum.
The cooling end of the semiconductor cooling module 31 is plate-shaped and attached to the bottom plate of the heat sink 32, and the heat sink 32 is cooled by the heat transfer principle. The fins are placed in a space defined by the bottom plate connected thereto and the box 33 made of a heat insulating material. The space is also sealed from the outside atmosphere. When hot gas from the closed box 1 enters the space, it passes through the cooled fins of the heat sink 32, in which process the hot gas is cooled. The cooled gas is sent back to the closed box 1 by the fan 5. That is, the cooling end of the semiconductor cooling module 31 cools the fin via the bottom plate of the heat sink 32, and the hot gas is cooled in this space. Further, since the space is surrounded by the heat insulating case 33, the temperature of the space is hardly affected by the external temperature, and the gas is efficiently cooled.
The closed box body 1, the semiconductor refrigeration component 3 and the fan 5 can be connected through connecting pipes to be communicated in a closed mode, and a closed gas circulation loop is formed. For example, the input end of the refrigeration component 3 is hermetically communicated with the air outlet of the shielding box body, the negative pressure end of the fan 5 is hermetically communicated with the output end of the refrigeration component 3, and the positive pressure end of the fan 5 is hermetically communicated with the air inlet of the shielding box body 1. The term "hermetically communicated" as used herein means that the internal gas is isolated from the external atmosphere and cannot be exchanged with the external atmosphere, but circulates only in the internal circuit.
Alternatively, referring to fig. 1, a bottom radiation shielding box 7 may be provided at one side of the bottom of the closed box body 1, and mounted on the shielding box body 1 to cover the air inlet. Fig. 3 is a partial cross-sectional view of a bottom radiation shielded box. The bottom radiation shield 7 has a shield lead plate 71, a shield box body 72, a gasket 73, and a flange joint 74. A communication hole through which gas flows is formed in a lower side wall portion of the sealed case 1. The bottom radiation shielding box 7 is also provided with communication holes in its side walls corresponding to the holes in the side walls of the closed box body 1 so that the gas in the bottom radiation shielding box 7 can flow into the closed box body 1.
The wall of the shield case body 72 other than the wall 75 joined to the sealed case body 1 is adhered to the shield case lead plate 71. The wall 75 of the shield case body 72, which is joined to the sealed case body 1, is joined to the sealed case body 1 via the gasket 73. The provision of the gasket 73 effectively isolates the internal gas from the external atmosphere. A threaded hole is provided in the wall 75. The bottom radiation shielding box 7 is connected with the closed box body 1 through screws. Because the screw holes are positioned in the coverage range of the box body shielding lead plate 71, radiation leakage of the screws and the screw holes is effectively shielded.
Further, a communication hole is opened in a wall orthogonal to the wall 75, and is connected to the intake pipe 6 through a flange joint 74. The bottom radiation shield 7 can be easily connected to the inlet manifold 6 by virtue of the flange joint 74. The communication hole of the bottom radiation shielding box 7 with the intake duct 6 may be provided at other positions as long as the position does not oppose the communication hole of the bottom radiation shielding box 7 with the sealed case 1. That is, the position may be set so that the radiation in the sealed case 1 does not enter the communication hole with the inlet pipe 6 through the communication hole with the sealed combination 1.
The bottom radiation shielding box 7 is hermetically communicated with the positive pressure end of the fan 5 through an air inlet pipe 6.
Therefore, according to the above, the bottom radiation shielding case 7 includes the communication hole with the sealed case 1 and the communication hole with the intake duct 6, and a misalignment is generated between both the holes, so that an effective radiation shielding effect can be achieved.
Alternatively, referring to fig. 1, a top radiation shielding box 8 may be disposed on the top of the sealed box body 1, and the top radiation shielding box 8 is installed on the shielding box body 1 to cover the air outlet of the sealed box body 1.

The top radiation shielding box 8 is provided with a communication hole corresponding to the air outlet of the closed box body 1 at the bottom of the side wall so that the gas in the closed box body 1 flows into the top radiation shielding box 8. A communication hole is provided in a side wall of the top radiation shielding box 8 orthogonal to the side wall communicating with the air outlet, for communicating with the air suction pipe 2. The top radiation shielding box 8 and the semiconductor refrigeration assembly 3 can be hermetically communicated through the air suction pipe 2. The top radiation shield 8 has the same construction and effect as the bottom radiation shield 7 and will not be described in detail here.
Alternatively, as an embodiment, for example, as shown in fig. 1, the following connection structure is specifically adopted. The negative pressure end of the fan 5 is connected with the air outlet of the closed box body 1 through the connecting pipe 4, the semiconductor refrigerating assembly 3, the air suction pipe 2 and the top radiation shielding box 8. The positive pressure end of the fan 5 is connected with the air inlet of the closed box body 1 through an air inlet pipe 6 and a bottom radiation shielding box 7. The top hot air of airtight box body 1 gets into refrigeration subassembly 3 through top radiation shielding box 8, breathing pipe 2, and the hot air is cooled off in refrigeration subassembly 3, gets into the negative pressure end of fan 5 through connecting pipe 4, passes through intake pipe 6, bottom radiation shielding box 7 by the malleation end of fan 5 and sends into the air inlet of airtight box body 1 to realize the circulative cooling of gaseous in the airtight box body.
In the above embodiments, the fan is used as a power source for circulating air, and as an alternative embodiment, other power sources, such as a vacuum pump, may be used, where the air inlet is communicated with the air outlet.
In addition, the refrigerating device adopted in the embodiment increases the temperature difference of the circulating air for heat dissipation, and effectively improves the heat dissipation capacity. As an alternative embodiment, the refrigeration device is not limited to the semiconductor heat dissipation assembly, and an air-pressure refrigerator or the like may be used. The cooling device may be, for example, a cooling device that performs cooling when a preset condition is satisfied, and for example, a temperature sensor may be provided to perform cooling when the temperature is higher than a predetermined value.
In addition, the embodiment of the present invention adopts an L-shaped closed box, and as an alternative embodiment, the closed box is not limited to an L-shaped closed box, and may have any shape according to design requirements.

In addition, in the embodiment of the present invention, the refrigeration assembly is disposed between the negative pressure end of the power source and the gas outlet of the sealed box, but is not limited thereto. As an alternative embodiment, the refrigeration component can also be arranged between the positive pressure end of the power source and the air inlet of the closed box body.
According to the above structure of the utility model, can realize that the air in the airtight box body does not exchange with external environment, can ensure the humidity of air in the box body effectively. In addition, according to the present invention, since the heat exchange medium is air, it is possible to avoid contamination and damage to the electric element due to possible leakage of the oil cooling or the water cooling, compared with the oil cooling or the water cooling. Additionally, according to the utility model discloses, compare with the air conditioner, power is little, and the size is little, and the noise is low.
