Referring to fig. 1 and 2, fig. 1 is a perspective view showing a ventilation cooling system in an embodiment of the present invention, and fig. 2 is a perspective view showing the ventilation cooling system shown in fig. 1, which is used in a CT security inspection machine, and as can be seen from fig. 2, the CT security inspection machine includes a rotor 1 and a security inspection passage 2 passing through the rotor 1 along an axis of the rotor 1. With continued reference to FIG. 2, in some embodiments, the ventilation cooling system of the present invention comprises: the shell 3 is arranged outside the CT security inspection machine and seals the CT security inspection machine, and the ventilation system, the refrigeration system and the CT security inspection machine are arranged in the shell 3 together. So set up, casing 3 forms the environment isolated with outside relatively for CT security check machine, and ventilation system, refrigerating system can adjust the environmental parameter in the casing 3 such as temperature, humidity to guarantee that CT security check machine can have good operational environment. The unified arrangement of the ventilation system and the refrigeration system in the housing 3 also helps to reduce the space occupation of the whole ventilation cooling system.

Specifically, as shown in fig. 1 and fig. 2, air inlets 41 are disposed at positions of the casing 3 corresponding to two ends of the security inspection channel 2, an air outlet 42 is disposed at a position of the casing 3 corresponding to the rotor 1, an air inlet component is disposed at the air inlet 41, and an air outlet component is disposed at the air outlet 42. Since the rotor 1 is a major heating area of the CT security inspection machine, and the temperatures at both ends of the security inspection passage 1 are lower than those of the rotor 1, by arranging the air outlet 42 and the air inlet 41 in this way, the air outside the casing 3 will be naturally introduced into the casing 3 from the air inlet 41, and the air inside the casing 3 will be naturally exhausted from the air outlet 42 out of the casing 3. The air flow in the shell 3 is enhanced under the assistance of the air inlet component and the air exhaust component, and the flowing air enables the heat and the moisture in the shell 3 to be taken away quickly, so that the working environment of the CT security inspection machine in the shell 3 is adjusted.

The refrigeration system comprises an integrated air conditioner 50 installed on the shell 3, the integrated air conditioner 50 is provided with an air conditioner air outlet 51 and an air conditioner air suction inlet 52, the air conditioner air outlet 51 faces the rotor 1, and the air conditioner air suction inlet 52 is far away from the rotor 1. Compare split type air conditioner among the conventional art, integral type air conditioner 50's space occupies littleer, is convenient for arrange in the limited casing 3 in space to because integral type air conditioner 50 can be with the comdenstion water self-evaporation in the work, this has just also solved the problem that air conditioner comdenstion water is difficult to discharge among the CT security check machine operational environment. Through the air-conditioning outlet 51 with integral type air conditioner 50 towards rotor 1, the cold air of integral type air conditioner 50 output makes the CT security check machine during operation mainly by the heat that rotor 1 produced take the lead and obtain effective control to spread gradually to whole casing 3 in, make calorific capacity security check passageway 2 less relatively also can be by the cooling and be in suitable operational environment. The temperature of the cold air is gradually increased after the cold air fully exchanges heat with the CT security inspection machine, the air after temperature rise can be sucked into the integrated air conditioner 50 again by the air conditioner air suction opening 52 far away from the rotor 1 for refrigeration, and then the air is blown to the rotor 1 from the air conditioner air outlet 51, so that the internal circulation of the air in the shell 3 is realized.

Through the analysis, the ventilation cooling system is easy to know, and compared with the traditional technical scheme, the ventilation cooling system has small change of the whole size after being installed on the CT security inspection machine, and can adapt to the original working environment of the CT security inspection machine without special change. The ventilation cooling system fully considers the heat distribution characteristic of the CT security inspection machine during working, separates the CT security inspection machine from the external environment by arranging the shell, can effectively cool and dehumidify the whole CT security inspection machine under the matching of the refrigeration system and the ventilation system, and can not generate condensate water which is difficult to process in the cooling process. In conclusion, the ventilation and cold air system disclosed by the invention can well meet the requirements of cooling and dehumidifying the CT security inspection machine, and has the advantages of low overall installation complexity and better wide application adaptability.

It will be appreciated that the ventilation cooling system of the present invention is not strictly limited as to how the housing 3 is constructed. The housing 3 may be made by splicing metal plates or may be made of other rigid materials. Preferably, in order to improve the cooling efficiency of the integrated air conditioner 50, the housing 3 should be thermally insulated from the outside thereof, for example, a thermal insulation material layer such as foam may be laid on the inside thereof. Similarly, there are no specific requirements regarding the specific shape of the housing 3, but overall the housing 3 should have as little space occupation as possible. For example, as shown in fig. 1, the housing 3 can be divided into three parts, which respectively correspond to the rotor 1 and the security inspection channels 2 on both sides of the rotor 1, and the size of each part of the housing 3 should be as large as possible to fit the size of the content.

As shown in fig. 3, in some embodiments, the ventilation cooling system of the present invention preferably includes an insulation space 31 isolated from the CT security inspection machine in the housing 3, the integrated air conditioner 50 is disposed in the insulation space 31, and the insulation space 31 is provided with a ventilation opening communicating with the outside of the housing 3. The arrangement of the heat insulation space 31 can prevent heat generated by the integrated air conditioner 50 during working from being dissipated to other parts in the shell 3, so that the cooling efficiency of the ventilation cooling system for the CT security inspection machine is ensured, meanwhile, a part of cold air generated by the integrated air conditioner 50 can be prevented from being used for self heat dissipation, and the energy consumption of the integrated air conditioner 50 is reduced. Moreover, by isolating the integrated air conditioner 50 in the heat insulation space 31, condensed water vapor after self-evaporation of condensed water can be directly discharged to the outside of the casing 3 from the vent of the heat insulation space 31, and cannot be condensed again to form condensed water on the inner wall of the casing 3 due to lower temperature of the inner wall of the casing 3, so that the humidity adjustment inside the casing 3 is influenced.

In particular, as a practical example, the insulating space 31 may be defined by several partitions 311 cooperating with the casing 3, as shown in fig. 3, the partitions 311 being made of a thermally insulating material, such as a foam. On this basis, the heat insulating space 31 preferably has a sound insulating function to reduce the disturbance of the operating noise of the integrated air conditioner 50 to the outside. In order to achieve the sound insulation effect, for example, a sound absorbing material such as the aforementioned foam may be selected as a constituent material of the heat insulating space 31. Of course, some sound absorption structures commonly used in the acoustic field may be disposed in the heat insulation space 31 to achieve the noise reduction effect, and the present application is not limited in this respect.

In some embodiments, as shown in fig. 3, the insulation space 31 is further provided with a downpipe 312 communicating with the outside of the housing 3. Since the heat insulating space 31 is provided with a vent communicating with the outside of the housing 3, there is a possibility that liquid enters the heat insulating space 31 from the outside of the housing 3 through the vent. By providing the downpipe 312, the liquid that accidentally enters the heat insulation space 31 can be discharged in time, avoiding affecting the integrated air conditioner 50 and even other components inside the housing 3.

In order to improve the space utilization of the housing 3, the ventilation cooling system of the present invention preferably arranges the heat insulating space 31 above the security inspection passage 2 and on one side of the rotor 1. Because security installations passageway 2 passes rotor 1 and sets up, consequently security installations passageway 2 and rotor 1 must have the difference in the direction of height's maximum dimension, and this difference can make full use of to insulate against heat space 31 setting here, can enough set up integral type air conditioner 50 in casing 3, can also guarantee the uniformity of casing 3 in whole height. Moreover, because integral type air conditioner 50 has the demand that gives off condensation steam with the external world, set up thermal-insulated space 31 in security installations passageway 2's top then allow thermal-insulated space 31 directly to set up the ventilation hole at casing 3's top, further simplified the inside structure of casing 3, improve space utilization. In addition, the integrated air conditioner 50 is disposed above the security inspection duct 1, so that the air outlet 51 thereof can be located at a relatively upper position with a relatively short path, and cool air can naturally sink downward to cool the entire space inside the housing 3.

Similarly, also in view of the sufficient utilization of the space in the housing 3, the ventilation and cooling system of the present invention preferably has the air inlet 41 disposed below the safety inspection passage 2 and the air outlet 42 disposed above the rotor 1. As is well known, the hot air tends to float upwards compared with the cold air, and after the air intake assembly and the air exhaust assembly are started, the hot air in the shell 3 is driven to move from two ends of the CT security inspection machine to the middle and from the bottom to the upper part, and is exhausted from the air outlet 42 above the shell, so that the temperature and the humidity in the shell 3 are effectively reduced.

In some embodiments, as shown in fig. 4, the ventilation cooling system of the present invention further includes an exhaust duct 43 communicating the exhaust port 42 with an exhaust assembly 45, and the exhaust duct 43 may be a duct member independent from the housing 3 or a duct member cooperating with the housing 3. The position of the air exhaust assembly 45 in the housing 3 is more flexible due to the arrangement of the air exhaust duct 43, so that the air in the housing 3 can be exhausted out of the housing 3 better. Similarly, the ventilation cooling system of the present invention may also include an air inlet duct communicating the air inlet 41 with the air inlet assembly, so as to adjust the direction of the inlet air in the housing 3.

In some embodiments, the air inlet duct and the air outlet duct 43 may further include a heat insulation structure and/or a sound insulation structure therein to reduce the escape of the cold in the casing 3 through the air inlet 41 and the air outlet 42, and reduce the working noise of each component in the casing 3.

In some embodiments, a drain pipe 44 communicating with the outside of the housing may be disposed in the air inlet pipe and the air outlet pipe 43. When liquid accidentally enters through the air inlet 41 and the air outlet 42, the drain pipe 44 can timely discharge the liquid to avoid influencing various components in the shell 3.

In some embodiments, the air intake assembly and/or the air exhaust assembly are provided with a check valve. The provision of the check valve prevents reverse flow of air and prevents external high temperature and high humidity air from entering the inside of the casing 3 when the refrigeration system is operated.

It is understood that the air intake assembly and the air exhaust assembly in the foregoing embodiments may be any technical solutions commonly used in the art, such as a fan, and the application is not limited herein.

The ventilation cooling system can further comprise a temperature sensor and/or a humidity sensor and a control module, wherein the control module is electrically connected with the temperature sensor and/or the humidity sensor, the air inlet assembly, the air exhaust assembly and the integrated air conditioner. Because the heat of the rotor is the largest and the electric devices of the rotor are most easily influenced by the temperature and the humidity, the temperature and humidity sensor is arranged near the rotor of the CT security inspection machine. Signals are fed back to the control module through the temperature sensor and the humidity sensor, and the control module controls the starting and the stopping of the refrigerating system and the ventilation system.

As a specific example, when the temperature sensor feedback temperature has reached the target high value, the central controller controls the integrated air conditioner 50 to be turned on to lower the temperature inside the casing 3, and when the temperature sensor feedback temperature has fallen below the target low value, the central controller controls the integrated air conditioner 50 to be turned off.

Similarly, when the humidity fed back by the humidity sensor reaches a target high value, the central controller controls the air intake assembly and the air exhaust assembly of the ventilation system to be opened, so that the air flow in the shell 3 is enhanced to reduce the humidity in the shell 3, and when the humidity fed back by the humidity sensor is lower than the target low value, the central controller controls the air intake assembly and the air exhaust assembly to be closed.

It can be understood that under control module's control, ventilation system and refrigerating system can form the cooperation, for example ventilation system can start with refrigerating system in proper order, earlier through starting ventilation system to 3 internal environment's of casing temperature, humidity carry out preliminary reduction, close ventilation system and start refrigerating system and carry out thorough cooling dehumidification to 3 internal environment of casing afterwards. Of course, the ventilation system and the refrigeration system can be activated simultaneously, and those skilled in the art can make specific adjustments according to actual situations based on the technical teaching provided in the disclosure of the present application, which is not described herein again.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
