Description

Technical Field

[0001] The present invention relates to the technical field of energy storage containers, and in particular to a PCS exhaust device for a control room of an energy storage container. Background Art

[0002] Energy storage containers are devices used to store and manage electrical energy. They are usually modified from standard containers and integrate battery packs, power conversion equipment, control systems, and other necessary auxiliary equipment. They are widely used in scenarios such as renewable energy power generation systems, grid peak regulation, backup power supplies, and off-grid power systems. Energy storage containers usually adopt standard container sizes (such as 20 feet or 40 feet) for easy transportation and installation. Battery packs, inverters, charge controllers, cooling systems, and fire protection systems are integrated inside the container to form a complete energy storage system. The number of containers can be increased or decreased according to demand to adjust the energy storage capacity. It is suitable for various environmental conditions and is often used in areas with power shortages or harsh environments. The prefabricated design and convenient transportation methods allow it to be quickly deployed on site. It is used in combination with renewable energy systems such as solar power generation and wind power generation to solve the problem of intermittent power generation and improve energy utilization efficiency. It releases stored electrical energy during peak power demand periods to balance the grid load and stabilize grid operation. It provides emergency power guarantee in the event of power outages or unstable power supply. It is used in remote areas or areas without grid coverage to provide independent power supply. Provide high-quality, uninterrupted power supply for factories, data centers, etc., reduce electricity costs and improve power supply reliability.

[0003] The PCS exhaust device in the energy storage container control room is an important component to ensure that the equipment operates stably under suitable temperature and ventilation conditions. The power conversion equipment will generate a lot of heat during operation. The exhaust device keeps the equipment within a safe operating temperature range by exhausting hot air and introducing cold air. The PCS exhaust device maintains air circulation inside the control room to prevent local overheating and extend the life of the equipment. The PCS exhaust device can reduce equipment failures caused by overheating and improve system reliability through proper exhaust and temperature control. However, the existing exhaust devices are large in size and cannot achieve rapid cooling and heat dissipation of key heat-generating components. When used under high load or high temperature environments, the safety and efficiency of the PCS module are difficult to guarantee.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a PCS exhaust device for the control room of an energy storage container to solve the above technical problems. Summary of the invention

[0005] The technical purpose to be achieved by the present invention is to design a PCS exhaust device for the control room of an energy storage container. When the PCS is working at high temperature, rapid exhaust and cooling can be performed on the basis of the original cooling device (such as air conditioning), thereby ensuring the working stability and safety of the PCS.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] A PCS exhaust device for a control room of an energy storage container comprises a container body, a battery module, an electrical control cabinet and a PCS module, wherein the battery module is installed inside the container body, and the electrical control cabinet is installed on the side of the battery module; the device also comprises a heat conduction mechanism, a refrigeration mechanism and an exhaust assembly; the heat conduction mechanism is installed outside the PCS module, and the heat conduction mechanism evaporates and absorbs the heat on the surface of the PCS module through a heat conduction pipe, thereby taking away a large amount of heat to achieve heat dissipation; the refrigeration mechanism is installed above the heat conduction mechanism, and the refrigeration mechanism introduces compressed air through an air inlet pipe to form a vortex in a collecting block, and then diverts the hot and cold airflows, wherein the cold airflow dissipates heat and cools down the heat conduction mechanism through the cold air pipe, and the exhaust assembly is installed below the refrigeration mechanism.

[0008] Preferably, the heat conduction mechanism includes a heat pipe, an exchange disk, heat sink fins and a connecting pipe, and each part cooperates with each other to achieve efficient heat dissipation. The heat pipe is installed on the surface of the PCS module and is responsible for quickly transferring the heat on the surface of the module to other components. The exchange disk is installed on the side of the PCS module and serves as a relay station for heat conduction to further transfer the heat from the heat pipe. The heat sink fins are installed on the side of the exchange disk to accelerate heat dissipation by increasing the heat dissipation area. The connecting pipe is installed inside the heat sink fins to play a connecting and heat conducting role, ensuring that heat can be smoothly transferred between various heat dissipation components. Through the organic combination of these components, the heat conduction mechanism can effectively dissipate the heat generated by the PCS module in a timely manner to ensure its normal operation.

[0009] Preferably, the heat sink fins are arranged in groups of two, and each group of heat sink fins is installed in a mirrored manner, thereby optimizing heat distribution and heat dissipation. Through this symmetrical design, the heat sink fins can more evenly disperse the heat from the exchange disk and improve the overall heat dissipation efficiency. The connecting pipe is arranged in a U shape, which further enhances the heat conduction performance. This design allows heat to flow smoothly between each fin group to avoid local overheating. The number of the connecting pipes is two, and the two connecting pipes are interconnected to form a continuous circulation path. This configuration ensures that heat can be efficiently transferred from one fin group to another, improves the overall heat dissipation capacity of the heat conduction mechanism, and ensures that the PCS module can still maintain a stable temperature during long-term operation.

[0010] Preferably, the heat pipe is composed of a pipe body, a cavity, a drainage block and a drainage groove, and each component is exquisitely designed and works together to achieve the best heat dissipation effect. The pipe body is installed on the surface of the PCS module, and its four corners are rounded, which not only improves the pressure resistance and durability of the pipe body, but also reduces the stress concentration problem caused by sharp corners. The pipe body is made of pure copper, and copper can conduct heat quickly and effectively due to its excellent thermal conductivity. A cavity is provided inside the pipe body, and the cavity is a cylindrical design. This design allows the heat to be evenly distributed inside the cavity, which helps to improve the overall heat dissipation efficiency.

[0011] Preferably, multiple drainage blocks are installed in a circular array inside the cavity. The design and arrangement of these drainage blocks can guide the heat flow, ensure that the heat is more evenly distributed in the heat pipe, and avoid the occurrence of local overheating. The drainage groove is set at the top of the drainage pipe, and through the clever fluid dynamics design, it can effectively accelerate the flow and discharge of the liquid heat transfer medium. The setting of the drainage groove allows the liquefied coolant to quickly flow back through capillary action, thereby improving the overall heat dissipation efficiency.

[0012] Preferably, the heat sink fins are composed of fin flanks and flat end faces. The fin flanks are located on both side portions of the heat sink fins, and their cross-sectional shape is a V-shaped design. This V-shaped structure not only increases the heat sink area, but also effectively guides the airflow and improves the heat sink efficiency. The flat end faces are located in the middle portion of the heat sink fins, providing a smooth heat transfer path so that the heat can be evenly distributed over the entire heat sink fin. Through this design, the fin flanks and the flat end faces cooperate with each other, which not only ensures the rapid conduction of heat, but also enhances the heat sink effect, ensuring that the heat sink fins can efficiently dissipate heat in actual applications and extend the service life of the equipment.

[0013] Preferably, the refrigeration mechanism is composed of a cold air pipe, a collecting block, an air inlet pipe, an air outlet pipe and an air outlet assembly, and each part is carefully designed to achieve an efficient cooling effect. The cold air pipe is installed on the exhaust block, and a cold air flow channel is opened inside. The cross-sectional shape of these cold air flow channels is set to an isosceles trapezoid. This design helps to optimize the distribution of airflow, improve the flow efficiency of cold air, and thus improve the cooling effect.

[0014] Preferably, the collecting block is installed on the side of the cold air pipe to guide and concentrate the cold air flow to a specific area. The design of the collecting block ensures that the cold air can be effectively collected and enter the cooling system through the air intake pipe. The air intake pipe is installed on the surface of the collecting block and is responsible for introducing external cold air into the flow channel of the cold air pipe. This design ensures the stability and continuity of the cold air flow in the cold air pipe.

[0015] Preferably, the air outlet pipe is installed on the other end face of the collecting block to discharge the cooled airflow out of the cold air pipe. Its design is to ensure that the cooled airflow can smoothly leave the cooling area to avoid airflow stagnation and reduced efficiency. Finally, the air outlet assembly is installed at the outermost end of the air outlet pipe, responsible for further guiding and discharging the cold air, ensuring that the system can efficiently discharge heat.

[0016] Preferably, a vortex chamber and a return flow channel are provided inside the collecting block; the vortex chamber is arranged in a ring shape, the vortex chamber is arranged to be connected to the air intake pipe, and the return flow channel is opened in the middle of the vortex chamber.

[0017] Preferably, the outlet pipe is exquisitely designed inside, including a diverter cavity and a transition cavity, to optimize the discharge and transition of the airflow. The diverter cavity is opened in the middle part of the outlet pipe, and its design purpose is to evenly distribute the discharged airflow to different areas of the pipe, reduce the unevenness of the airflow during the discharge process, and thus improve the efficiency of airflow discharge.

[0018] Preferably, the transition cavity is arranged at the outermost end of the air outlet pipe, and adopts a radial design with a small outer diameter and a large inner diameter. This radial structure enables the airflow to diffuse and transition smoothly when passing through the transition cavity, reduces the resistance of the airflow, and promotes the smooth discharge of the airflow. Through this optimized design, the air outlet pipe can effectively guide and discharge the cooling airflow efficiently, thereby improving the performance and stability of the overall cooling system.

[0019] Preferably, the air outlet assembly is composed of a sleeve block, a flow block and an air outlet, and the design purpose is to optimize the airflow discharge and the heat dissipation efficiency of the system. The sleeve block is installed at the outermost end of the air outlet pipe as the final outlet of the airflow to ensure that the cold air can be discharged smoothly from the pipe. The design of the sleeve block takes into account the uniform discharge of the airflow and the sealing of the system.

[0020] Preferably, the baffle is installed in the middle of the sleeve, and its main function is to adjust the direction and speed of the airflow. Through precise design, the baffle can effectively guide the airflow and reduce the flow resistance, thereby improving the exhaust efficiency. The baffle is provided with air outlet holes around it, which are designed in a spiral shape to make the airflow form a rotating flow during the exhaust process, so as to increase the diffusion area of ​​the airflow and further improve the heat dissipation effect of the gas.

[0021] Preferably, the exhaust block includes an exhaust block and a connecting pipe. The exhaust block is installed on the heat conduction mechanism and has a stepped structure. This design not only enhances its stability, but also effectively guides the air flow and optimizes the heat dissipation effect. The connecting pipe is installed at one end of the refrigeration mechanism and is responsible for connecting the exhaust block with other cooling components. The design of the connecting pipe ensures that the airflow can be smoothly guided from the refrigeration mechanism to the exhaust block. Through this synergistic effect, the efficiency of the overall heat dissipation system is improved.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention sets a heat conduction mechanism, and the principle of vaporization heat dissipation utilizes the phase change of the working fluid (from liquid to gas) to quickly take away the heat. The liquid absorbs a large amount of heat during the evaporation process and is converted into gas. This process can effectively absorb and transfer heat from the heat source (such as the PCS module), significantly improving the heat dissipation efficiency. Compared with traditional heat conduction or convection heat dissipation methods, vaporization heat dissipation can handle more heat and is suitable for application scenarios with high heat loads. Through efficient vaporization heat dissipation, the system can maintain a relatively stable temperature. The heat is quickly taken away and transferred to the heat dissipation area, so that the PCS module will not cause performance degradation or equipment failure due to overheating during operation. Maintaining a stable temperature is crucial to ensuring the long-term stability and reliability of the PCS module.

[0024] 2. Compared with the traditional air-cooled heat dissipation system, the refrigeration mechanism provided in the present invention generates a high-speed vortex flow, which allows the gas to be quickly mixed and cooled in the vortex tube. The rotating flow of the high-speed airflow in the vortex tube effectively improves the heat exchange efficiency and can quickly take away a large amount of heat. This efficient heat dissipation capability enables the vortex tube to perform well in applications that handle high heat loads. The vortex tube heat dissipation system only needs to rely on gas as the cooling medium, without the need for external coolant or a complex cooling system. This simplifies the design and maintenance of the heat dissipation system, reducing operating costs and system complexity.

[0025] 3. The design of the PCS exhaust device of the present invention takes into account the multiple requirements of the energy storage system in actual operation. Through the synergistic effect of the heat conduction mechanism, the refrigeration mechanism and the exhaust assembly, it ensures that the temperature of each module in the container control room can be maintained within a reasonable range. This not only ensures the stability and safety of the equipment, but also improves the overall operating efficiency of the system, providing a reliable guarantee for the long-term stable operation of the energy storage system. This innovative heat dissipation solution will significantly improve the performance and reliability of the energy storage container in actual applications, and has important practical application value.

DETAILED DESCRIPTION

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figure 1-8As shown, a PCS exhaust device for the control room of an energy storage container includes a container body 1, a battery module 2, an electrical control cabinet 3 and a PCS module. The device achieves efficient heat dissipation and stable operation through a variety of precise designs and device collaboration. The energy storage container body 1 is the basic structure of the entire device, providing a closed space to protect the internal equipment from the external environment. The battery module 2 and the electrical control cabinet 3 are configured inside. The battery module 2 is installed inside the container body 1, and the electrical control cabinet 3 is installed on the side of the battery module 2, which is responsible for managing and controlling the electrical part of the entire system. As one of the core components, the PCS module handles the conversion and management of electric energy and is a key part of the normal operation of the entire energy storage system. In order to effectively solve the heat problem generated during the operation of the PCS module, the device is specially designed with a heat conduction mechanism 5, a refrigeration mechanism 6 and an exhaust assembly 7. The heat conduction mechanism 5 is installed on the outside of the PCS module, and the heat on the surface of the PCS module is evaporated and absorbed through the heat conduction pipe 51, thereby taking away a large amount of heat to achieve heat dissipation. This heat conduction mechanism can not only quickly reduce the temperature of the PCS module, but also ensure that it remains stable during high-load operation. The refrigeration mechanism 6 is installed above the heat-conducting mechanism 5, which further improves the heat dissipation effect. The refrigeration mechanism 6 introduces compressed air into the collecting block 62 through the air inlet pipe 63 to form a vortex. Through the clever airflow distribution design, the refrigeration mechanism 6 can divert the hot and cold airflows, wherein the cold airflow dissipates heat and cools the heat-conducting mechanism 5 through the cold air pipe 61. This process effectively enhances the heat dissipation capacity of the heat-conducting mechanism 5, allowing the PCS module to operate within a more suitable temperature range, extending its service life and improving the overall efficiency of the system. In order to ensure that the heat can be discharged in time, the exhaust assembly 7 is installed below the refrigeration mechanism 6. The exhaust assembly 7 discharges hot air from the inside of the container through the exhaust fan and air duct design to form a good air circulation. This not only helps to maintain the temperature balance in the container, but also prevents heat from accumulating inside, thereby avoiding equipment failure or safety hazards caused by overheating.

[0039] like Figure 3 As shown, the heat conduction mechanism 5 includes a heat pipe 51, an exchange disk 52, heat dissipation fins 53 and a connecting pipe 54, and each part cooperates with each other to achieve efficient heat dissipation. The heat pipe 51 is installed on the surface of the PCS module, and is responsible for quickly transferring the heat on the surface of the module to other components. The exchange disk 52 is installed on the side of the PCS module, and serves as a relay station for heat conduction, further transferring the heat transmitted from the heat pipe 51. The heat dissipation fins 53 are installed on the side of the exchange disk 52, and accelerate the heat dissipation by increasing the heat dissipation area. The connecting pipe 54 is installed inside the heat dissipation fins 53, which plays a connecting and heat-conducting role, ensuring that the heat can be smoothly transferred between the various heat dissipation components. Through the organic combination of these components, the heat conduction mechanism 5 can effectively dissipate the heat generated by the PCS module in a timely manner to ensure its normal operation.

[0040] like Figure 5 As shown, the heat sink fins 53 are arranged in groups of two, and each group of heat sink fins 53 is installed in a mirrored manner, thereby optimizing heat distribution and heat dissipation. Through this symmetrical design, the heat sink fins 53 can more evenly disperse the heat from the exchange disk 52 and improve the overall heat dissipation efficiency. The connecting pipe 54 is arranged in a U shape, which further enhances the heat conduction performance. This design allows heat to flow smoothly between each fin group to avoid local overheating. The number of the connecting pipes 54 is 2, and the two connecting pipes 54 are interconnected to form a continuous circulation path. This configuration ensures that heat can be efficiently transferred from one fin group to another fin group, improves the overall heat dissipation capacity of the heat conduction mechanism 5, and ensures that the PCS module can still maintain a stable temperature during long-term operation.

[0041] like Figure 4 As shown, the heat pipe 51 is composed of a tube body 511, a cavity 512, a drainage block 513 and a drainage groove 514. Each component is exquisitely designed and works together to achieve the best heat dissipation effect. The tube body 511 is installed on the surface of the PCS module, and its four corners are rounded, which not only improves the pressure resistance and durability of the tube body 511, but also reduces the stress concentration problem caused by sharp corners. The tube body 511 is made of pure copper. Copper can conduct heat quickly and effectively due to its excellent thermal conductivity. A cavity 512 is provided inside the tube body 511. The cavity 512 is a cylindrical design. This design allows the heat to be evenly distributed inside the cavity 512, which helps to improve the overall heat dissipation efficiency.

[0042] Inside the cavity 512, a plurality of drainage blocks 513 are installed in a circular array. The design and arrangement of these drainage blocks 513 can guide the heat flow, ensure that the heat is more evenly distributed in the heat pipe 51, and avoid the occurrence of local overheating. The drainage groove 514 is set at the top of the drainage pipe, and through the clever fluid dynamics design, it can effectively accelerate the flow and discharge of the liquid heat transfer medium. The setting of the drainage groove 514 allows the liquefied coolant to quickly flow back through capillary action, thereby improving the overall heat dissipation efficiency.

[0043] like Figure 5As shown, the heat sink fin 53 is composed of a fin wing 531 and a flat end surface 532. The fin wing 531 is located on both sides of the heat sink fin 53, and its cross-sectional shape is a V-shaped design. This V-shaped structure not only increases the heat dissipation area, but also effectively guides the airflow and improves the heat dissipation efficiency. The flat end surface 532 is located in the middle part of the heat sink fin 53, providing a smooth heat transfer path so that the heat can be evenly distributed on the entire heat sink fin 53. Through this design, the fin wing 531 and the flat end surface 532 cooperate with each other, which not only ensures the rapid conduction of heat, but also enhances the heat dissipation effect, ensuring that the heat sink fin 53 can efficiently dissipate heat in actual applications and extend the service life of the equipment.

[0044] like Figure 6-7 As shown, the refrigeration mechanism 6 is composed of a cold air pipe 61, a collecting block 62, an air inlet pipe 63, an air outlet pipe 64 and an air outlet assembly 65, and each part is carefully designed to achieve an efficient cooling effect. The cold air pipe 61 is installed on the exhaust block, and a cold air flow channel 611 is opened inside. The cross-sectional shape of these cold air flow channels 611 is set to an isosceles trapezoid. This design helps to optimize the distribution of airflow, improve the flow efficiency of cold air, and thus improve the cooling effect.

[0045] The collecting block 62 is installed on the side of the cold air pipe 61, and plays the role of guiding and concentrating the cold air flow to a specific area. The design of the collecting block 62 ensures that the cold air can be effectively collected and enter the cooling system through the air inlet pipe 63. The air inlet pipe 63 is installed on the surface of the collecting block 62 and is responsible for introducing the external cold air into the flow channel of the cold air pipe 61. This design ensures the stability and continuity of the cold air flow in the cold air pipe 61.

[0046] The air outlet pipe 64 is installed on the other end face of the collecting block 62 to discharge the cooled airflow out of the cold air pipe 61. Its design is to ensure that the cooled airflow can smoothly leave the cooling area to avoid airflow stagnation and reduced efficiency. Finally, the air outlet assembly 65 is installed at the outermost end of the air outlet pipe 64, responsible for further guiding and discharging the cold air to ensure that the system can efficiently discharge heat.

[0047] A vortex chamber 621 and a return flow channel 622 are provided inside the collecting block 62 ; the vortex chamber 621 is arranged in a ring shape, the vortex chamber 621 is arranged to communicate with the intake pipe 63 , and the return flow channel 622 is opened in the middle of the vortex chamber 621 .

[0048] The outlet pipe 64 is exquisitely designed inside, including a diverter cavity 641 and a transition cavity 642, to optimize the discharge and transition of the airflow. The diverter cavity 641 is opened in the middle part of the outlet pipe 64, and its design purpose is to evenly distribute the discharged airflow to different areas of the pipe, reduce the unevenness of the airflow during the discharge process, and thus improve the efficiency of airflow discharge.

[0049] The transition cavity 642 is arranged at the outermost end of the outlet pipe 64, and adopts a radial design with a small outer diameter and a large inner diameter. This radial structure enables the airflow to diffuse and transition smoothly when passing through the transition cavity 642, reduces the resistance of the airflow, and promotes the smooth discharge of the airflow. Through this optimized design, the outlet pipe 64 can effectively guide and discharge the cooling airflow efficiently, thereby improving the performance and stability of the overall cooling system.

[0050] like Figure 7 As shown, the air outlet assembly 65 is composed of a sleeve block 651, a flow block 652 and an air outlet 653, and is designed to optimize the airflow discharge and the heat dissipation efficiency of the system. The sleeve block 651 is installed at the outermost end of the air outlet pipe 64 as the final outlet of the airflow to ensure that the cold air can be discharged smoothly from the pipe. The design of the sleeve block 651 takes into account the uniform discharge of the airflow and the sealing of the system.

[0051] The baffle block 652 is installed in the middle of the sleeve block 651, and its main function is to adjust the direction and speed of the airflow. Through precise design, the baffle block 652 can effectively guide the airflow and reduce the flow resistance, thereby improving the exhaust efficiency. The baffle block 652 is provided with air outlet holes 653 around it. These air outlet holes 653 are designed to be spiral in shape, so as to form a rotating flow of the airflow during the exhaust process, thereby increasing the diffusion area of ​​the airflow and further improving the heat dissipation effect of the gas.

[0052] like Figure 8 As shown, at the same time, the exhaust assembly 7 includes an exhaust block 71 and a connecting pipe 72. The exhaust block 71 is installed on the heat conducting mechanism 5 and has a stepped structure. This design not only enhances its stability, but also effectively guides the air flow and optimizes the heat dissipation effect. The connecting pipe 72 is installed at one end of the refrigeration mechanism 6 and is responsible for connecting the exhaust block 71 with other cooling components. The design of the connecting pipe 72 ensures that the airflow can be smoothly guided from the refrigeration mechanism 6 to the exhaust block 71. Through this synergistic effect, the efficiency of the overall heat dissipation system is improved.

[0053] During the working process of the present invention, when the power is low or the ambient temperature is low, the refrigeration mechanism 6 does not operate, and an air conditioner is provided in the energy storage container control room to cool the inside of the energy storage container control room, and the heat conduction mechanism 5 can accelerate the cooling speed of the PCS:

[0054] The heat pipe 51 is spread over the entire surface of the PCS module 4. The heat of the PCS module 4 is absorbed by the heat pipe 51, and the heat is transferred to the cavity 512 through the tube body 511. The cavity 512 is filled with a coolant. After being heated, the coolant will quickly vaporize to absorb a large amount of heat to achieve heat dissipation, and move to the exchange plate 52, and then enter the connecting pipe 54. The connecting pipes 54 are interconnected, so that even if the temperature of a certain surface of the PCS module 4 is high, the entire heat dissipation fin 53 can be used to quickly cool down this part of the heat. In order to avoid local waste, the heat dissipation fins 53 help the connecting pipe 54 to dissipate heat quickly. When the cold air brought by the air conditioner and the exhaust assembly 7 passes through the heat dissipation fins 53, it is first cooled quickly by the fin side wings 531, and then passes through the flat end surface 532. Due to the narrowing of the port, the air temperature is reduced again under the effect of the wind cooling effect, thereby realizing the rapid and uniform cooling of the entire heat dissipation fins 53; the cooled coolant is liquefied, and under the action of capillary action, it flows back along the drainage block 513 through the drainage groove 514 to achieve circulation;

[0055] When the energy storage container is at high temperature or works at high load for a long time, the PCS temperature inside the control room of the energy storage container will rise rapidly; at this time, the refrigeration mechanism 6 starts to work to achieve rapid cooling; the heat conduction mechanism 5 uses the air compressor of the air conditioner, and connects a conduit to the air compressor of the air conditioner to the air inlet pipe 63. The compressed air rotates rapidly when entering the vortex chamber 621, thereby forming internal and external vortices in the diversion chamber 641. Under the action of mutual friction, the speed of the outer vortex will be continuously accelerated by the internal energy, and the inner vortex will lose its internal energy and slow down. The inner and outer vortices are diverted in the transition chamber 642, and the hot air flow is discharged outside the container body 1 through the air outlet 653. The cold air flow is intercepted by the baffle block 652 and refluxes, and passes into the exhaust assembly 7 through the reflux channel 622 and the cold air flow channel 611;

[0056] The connecting pipe 72 transmits the cold air flow generated by the refrigeration mechanism 6 through the exhaust block 71 to quickly cool down the heat conduction mechanism 5 .
