Description

Technical Field

[0001] The utility model relates to the field of cold chain technology, and more specifically, to a cold chain transport compartment, and also to a cold chain transport vehicle comprising the cold chain transport compartment. Background Art

[0002] Cold chain transportation refers to the transportation process in which the goods are kept at a certain temperature. The cold chain transportation mode can be road transportation, water transportation, rail transportation, air transportation, or a combination of multiple transportation modes.

[0003] When a carriage is used for transportation, there are generally many types of goods being transported, and the temperature environments required are not necessarily the same. Therefore, at present, at least two compartments are often separated in the carriage by a partition, such as one is a refrigerator and the other is a freezer. Since different compartments require different temperature environments, two evaporators are generally provided in different compartments, and the two evaporators are connected in series or in parallel to the same mechanical refrigeration system.

[0004] In the existing system, for a compartment with both a freezer and a refrigerator, only one evaporator is provided, and the evaporator is provided in the freezer, and then an air supply passage is established between the freezer and the refrigerator so that the cold air in the freezer can be introduced into the refrigerator, so that the temperature of the refrigerator can be lowered.

[0005] After long-term practice, the inventors have found that the above-mentioned scheme often leads to the problem of local low temperature in the refrigerator, especially near the air outlet of the air supply channel, which may cause damage to the items; of course, the return air from the refrigerator to the freezer, due to the high return air temperature, may also cause the temperature of the freezer to be locally too high, causing damage to the internal items.

[0006] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art: the problem of excessively low local temperature in the compartment when changing air and adjusting temperature in separated compartments is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0007] In view of this, the first object of the utility model is to provide a cold chain transport compartment, which can effectively improve the problem of local low temperature in the compartment caused by air exchange and temperature adjustment in separated compartments. The second object of the utility model is to provide a cold chain transport vehicle including the above-mentioned cold chain transport compartment.

[0008] In order to achieve the above first purpose, the utility model provides the following technical solutions:

[0009] A cold chain transport compartment, comprising a compartment body, wherein the compartment body has a first compartment and a second compartment which are isolated from each other and can have different operating temperatures, and further comprising:

[0010] an air supply channel, one end of which extends to the first compartment so that a first air inlet provided thereon is located in the first compartment, and the other end of which extends to the second compartment so that the first air outlet is located in the second compartment;

[0011] a return air passage, one end of which extends to the second compartment so that a second air inlet provided thereon is located in the second compartment, and the other end of which extends to the first compartment so that the second air outlet is located in the first compartment;

[0012] The heat conducting member comprises a first side heat conducting portion and a second side heat conducting portion which can conduct heat to each other, wherein the first side heat conducting portion is exposed to the return air passage, and the second side heat conducting portion is exposed to the supply air passage.

[0013] When using the above-mentioned cold chain transport compartment, there is an obvious temperature difference between the temperature of the first compartment and the temperature of the second compartment. When the air in the first compartment is transported to the second compartment through the air supply channel, under some working conditions, the return air channel will correspondingly guide the air in the second compartment into the first compartment. Because the air in the return air channel comes from the second compartment, and the air in the supply air channel comes from the first compartment, the air temperature in the return air channel will be higher than the air temperature in the supply air channel, and closer to the gas temperature in the second compartment. Because the heat conductor conducts heat, heat conduction will be exchanged between the air in the return air channel and the air supply channel, so that the air temperature in the supply air channel changes to be closer to the second compartment, and then is discharged from the first air outlet to the second compartment; correspondingly, the air temperature in the return air channel can be changed to be closer to the first compartment, and then is discharged from the second air outlet to the first compartment. In the above-mentioned cold chain transport compartment, a heat conductor is added between the air supply channel and the return air channel to conduct heat between the air supply channel and the return air channel, so that the air outlet temperature of the air supply channel is closer to the temperature of the second compartment, and the air outlet temperature of the return air channel is closer to the temperature of the first compartment. It can avoid that the air outlet temperature of the first air outlet is too different from the temperature of the second compartment, thereby avoiding the situation where the items in the second compartment are affected. Similarly, it can avoid that the air outlet temperature of the second air outlet is too low compared to the temperature of the second compartment, thereby affecting the items in the first compartment. In summary, the above-mentioned cold chain transport compartment can effectively improve the problem of low local temperature in the compartment caused by air exchange and temperature adjustment between compartments.

[0014] In some technical solutions, a ventilation channel is included, and the heat conductive element is located in the ventilation channel to transversely divide the ventilation channel into the supply air channel and the return air channel.

[0015] In some technical solutions, it includes an enclosure, which encloses the ventilation passage; one end of the enclosure extends to the first compartment, and the other end extends to the second compartment; the enclosure is arranged at the inner corner of the compartment, one side edge of the enclosure is connected to one side wall of the inner corner, and the other side edge is connected to the other side wall of the inner corner.

[0016] In some technical solutions, the first side of the two sides of the heat conductor that are away from each other is connected to the inner corner, and the second side is connected to the enclosure; the side of the second side away from the air supply channel is against the enclosure.

[0017] In some technical solutions, the enclosure is a flat plate, a first edge of the enclosure is fixedly connected to the top wall of the compartment, and a second edge of the enclosure is fixedly connected to the left and right side walls of the compartment.

[0018] In some technical solutions, the upper channel of the heat conductor is the supply air channel, and the lower channel is the return air channel; the first air outlet is opened in the part of the enclosure corresponding to the supply air channel; the second air inlet is opened in the part of the enclosure corresponding to the return air channel.

[0019] In some technical solutions, the first air outlet is located on a side of the enclosure close to the top wall of the compartment; the second air inlet is located on a side wall of the enclosure close to an adjacent side of the compartment.

[0020] In some technical schemes, the ventilation passage is provided with a fan at one end of the first compartment, the first air inlet is formed at the end surface of the enclosure, and the end of the enclosure is abutted against the air outlet side of the fan and connected to the air outlet of the fan; the air inlet of the fan is arranged downward, and the second air outlet is opened at the end of the enclosure and arranged downward.

[0021] In some technical solutions, the enclosure has a heat insulating layer in the portion of the first compartment; and the thermal conductivity of the heat-conducting element is higher than the thermal conductivity of the enclosure.

[0022] In some technical solutions, the heat conductive member is extended along the extension direction of the air supply channel; one edge of the heat conductive member is connected to the channel wall on one side of the ventilation channel, and the other edge of the heat conductive member is connected to the channel wall on the other side of the ventilation channel.

[0023] In order to achieve the above-mentioned second purpose, the utility model also provides a cold chain transport vehicle, which includes any one of the above-mentioned cold chain transport compartments. Since the above-mentioned cold chain transport compartments have the above-mentioned technical effects, the cold chain transport vehicle having the cold chain transport compartment should also have corresponding technical effects.

[0032] The embodiment of the utility model discloses a cold chain transport compartment, which can effectively improve the problem of excessively low local temperature in compartments caused by air exchange and temperature adjustment in separated compartments.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-Figure 3 , Figure 1 A schematic diagram of the structure of the air duct partition of the temperature control system of the cold chain transport compartment provided by the embodiment of the utility model; Figure 2 A schematic diagram of the structure of a cold chain transport compartment provided by an embodiment of the utility model; Figure 3A schematic diagram of the partial cross-sectional structure of a cold chain transport compartment provided in an embodiment of the utility model.

[0035] In some embodiments, a temperature control system for a cold chain transport compartment is provided, which is used to adjust the temperature of a first compartment and a second compartment that are isolated from each other in the cold chain transport compartment. The temperature control system is used to adjust the temperature of the first compartment 100, and to transport the low-temperature gas of the first compartment 100 to the second compartment 200 through the air supply channel 10, so that the second compartment 200 is cooled down. Similarly, the gas of the second compartment 200 also needs to be introduced into the first compartment 100 through the return air channel 20 to balance the wind pressure. The air supply channel 10 and the return air channel 20 can exchange heat, so that the wind of the air supply channel 10 absorbs heat from the return air channel 20 and then is supplied to the second compartment 200, so that the temperature of the wind in the air supply channel 10 is further increased to avoid the problem of too low temperature.

[0036] It should be noted that the cold chain transport compartment indicated in each embodiment of the present application mainly includes a compartment, and at least two compartments are separated from the compartment, such as the first compartment 100 and the second compartment 200 mentioned above. Of course, in some embodiments, a third compartment or more compartments can be further separated. Generally speaking, the target temperature of the temperature control of the first compartment 100 and the second compartment 200 is not the same, and the former has a lower temperature. Among them, the first compartment 100 and the second compartment 200 can be expressed in at least the following ways: as one way, the first compartment 100 is a freezing chamber and the second compartment 200 is a refrigerating chamber; as another way, the first compartment 100 is a deep freezing chamber, and the second compartment 200 is a refrigerating chamber or a fresh ice chamber; as another way, the temperature control temperature of the first compartment 100 is about minus 18 degrees Celsius, and the temperature control temperature of the second compartment 200 is 2 to 6 degrees Celsius, and it is required that neither place can be lower than 0 degrees Celsius. The compartment body is divided into a first compartment 100 and a second compartment 200, or more compartments, generally in the front-to-back direction of the compartment body, and can also be divided in the up-down direction or the left-to-right direction. It should be noted that the forward direction in the context is the driving direction of the cold chain transport vehicle.

[0037] It should be noted that the cold chain transport compartment indicated in each embodiment of the present application may be a compartment of a cold chain transport vehicle. The cold chain transport vehicle is mainly a cold chain transport truck. Of course, this cold chain transport compartment may also be installed on transport vehicles such as trains, or may be set on transport aircraft, transport ships, etc.

[0038] In some embodiments, a temperature control system for a cold chain transport compartment is provided, which is used to adjust the temperature of a first compartment 100 and a second compartment 200 that are isolated from each other in a cold chain transport compartment. The system mainly includes an air supply channel 10, a return air channel 20 and a heat conducting member 2.

[0039] It should be noted that the first compartment and the second compartment separated in the compartment have different working temperatures during use, which may be due to the articles or because a refrigeration device is provided. Specifically, the refrigeration device 1 can be used to refrigerate the first compartment 100 so that the temperature of the first compartment is lower than room temperature, and the temperature of the second compartment can be controlled and adjusted by the temperature of the first compartment. The refrigeration device 1 is generally a mechanical refrigeration, and the specific refrigeration device 1 can be an evaporator, or of course other refrigeration equipment, such as a semiconductor refrigerator. The refrigeration device 1 can be installed in the first compartment 100 or outside the first compartment 100. When installed outside the first compartment 100, the cold air outlet of the refrigeration device 1 should be connected to the first compartment 100. For a cold chain transport vehicle, the first compartment 100 is generally in front of the second compartment 200. In order to facilitate the installation of the refrigeration device 1 and other equipment in the mechanical refrigeration system where the refrigeration device 1 is located, the refrigeration device 1 is generally installed on the side of the first compartment 100 away from the second compartment 200. In order to allow the first compartment 100 to have enough space to store more items, the refrigeration device 1 is generally arranged outside the first compartment 100, such as attached to the outside of the compartment, and the vent is directed toward the first compartment 100, and the vent is connected to the first compartment 100 through a channel opened on the compartment. Of course, in addition to the refrigeration device 1, other methods can be used to make the temperature of the first compartment 100 significantly lower than that of the second compartment 200, so that the gas in the first compartment 100 can cool the second compartment 200.

[0040] One end of the air supply passage 10 extends to the first chamber 100, so that the first air inlet 10-2 provided thereon is located in the first chamber 100 to communicate with the first chamber 100; the other end of the air supply passage 10 extends to the second chamber 200, so that the first air outlet 10-1 is located in the second chamber 200 to communicate with the second chamber 200. In this way, the low-temperature gas in the first chamber 100 can enter the air supply passage 10 through the first air inlet 10-2, then flow along the air supply passage 10 to flow to the second chamber 200, and then flow out from the first air outlet 10-1, that is, enter the second chamber 200. It should be noted that the flow of the wind in the air supply channel 10 can be realized by the fan 4 arranged at the air supply channel 10 to flow to the second compartment 200, such as an exhaust fan, a blower, etc.; of course, when there is a pressure difference between the first compartment 100 and the second compartment 200, such as the air pressure in the first compartment 100 is greater than the air pressure in the second compartment 200, the fan 4 is not arranged at this time, and the wind in the first compartment 100 can also enter the second compartment 200 through the air supply channel 10. It should be noted that extending to the compartment, that is, reaching the compartment, can be stopped at the compartment boundary, or can be further extended in the compartment.

[0041] One end of the return air passage 20 extends to the second compartment 200, so that the second air inlet 20-2 provided thereon is located in the second compartment 200 to communicate with the second compartment 200; the other end of the return air passage 20 extends to the first compartment 100, so that the second air outlet 20-1 is located in the first compartment 100 to communicate with the first compartment 100. In this way, the wind in the second compartment 200 can enter the return air passage 20 through the second air inlet 20-2, then flow along the return air passage 20 to flow to the first compartment 100, and then flow out from the second air outlet 20-1, that is, enter the first compartment 100. The function of the return air passage 20 is to make up for the imbalance of the air volume between the first compartment 100 and the second compartment 200 caused by the air supply of the air supply passage 10. It should be noted that the flow of air in the return air channel 20 can be realized by a fan arranged at the return air channel 20 to flow to the first compartment 100, such as an exhaust fan, a blower, etc.; of course, when there is a pressure difference between the first compartment 100 and the second compartment 200, such as the air pressure in the first compartment 100 is less than the air pressure in the second compartment 200, the air in the second compartment 200 can enter the first compartment 100 through the return air channel 20 without setting a fan. It should be noted that the specific formation method of the air supply channel 10 and the return air channel 20 is not required, and can also be formed by a plate body directly around the compartment, or a tube body can be set so that the air supply channel 10 and / or the return air channel 20 are formed in the tube cavity.

[0042] The heat-conducting member 2 is a heat-transferring member for transferring heat between the air supply channel 10 and the return air channel 20. Since the air supply channel 10 and the return air channel 20 have opposite flow directions, the temperature of the air in the air supply channel 10 is generally lower than the temperature of the air in the return air channel 20. Specifically, the heat-conducting member 2 includes a first side heat-conducting portion and a second side heat-conducting portion that can conduct heat to each other. The first side heat-conducting portion is exposed to the return air channel 20 so as to be able to exchange heat with the air in the return air channel 20, and the second side heat-conducting portion is exposed to the air supply channel 10 so as to be able to exchange heat with the air in the air supply channel 10. It should be noted that the heat-exchange member can be a high-efficiency heat-exchange device, such as a heat-exchange system; or it can be a general heat-exchange structure, such as a heat-exchange plate, a heat-exchange block, etc. When the heat-conducting member 2 is a heat-exchange plate, the two side plate surfaces of the heat-exchange plate can be respectively the first side heat-conducting portion and the second side heat-conducting portion. Of course, the two side edges of the heat-exchange plate along a certain extension direction of the plate surface can also be respectively the first side heat-conducting portion and the second side heat-conducting portion.

[0043] In some embodiments, when the above-mentioned cold chain transport compartment is used, it is set at the compartment body of the cold chain transport compartment. When the air in the first compartment 100 is transported to the second compartment 200 through the air supply duct 10, under some working conditions, the return air duct 20 will correspondingly guide the air in the second compartment 200 into the first compartment 100. Because the air in the return air duct 20 comes from the second compartment 200, and the air in the air supply duct 10 comes from the first compartment 100, the air temperature in the return air duct 20 will be higher than that in the air supply duct 10. The air temperature in the channel 10 is higher and closer to the gas temperature in the second compartment 200. Because the heat conducting member 2 is heat conducting, the air bodies in the return air channel 20 and the supply air channel 10 will exchange heat through heat conduction, so that the air temperature of the supply air channel 10 changes to be closer to the second compartment 200, and then is discharged from the first air outlet 10-1 to the second compartment 200; correspondingly, the air temperature of the return air channel 20 can be changed to be closer to the first compartment 100, and then is discharged from the second air outlet 20-1 to the first compartment 100. In the temperature control system of the above-mentioned cold chain transport compartment, a heat conducting member 2 is added between the supply air channel 10 and the return air channel 20, so that heat can be conducted between the supply air channel 10 and the return air channel 20, so that the air outlet temperature of the supply air channel 10 is closer to the temperature of the second compartment 200, and the air outlet temperature of the return air channel 20 is closer to the temperature of the first compartment 100. It can avoid the situation that the air outlet temperature of the first air outlet 10-1 is too low, causing the temperature of the second compartment 200 to be too low locally and affecting the items in the second compartment 200. Similarly, it can avoid the situation that the air outlet temperature of the second air outlet 20-1 is too high, causing the temperature of the first compartment 100 to be too high locally and affecting the items in the first compartment 100. In summary, the above-mentioned cold chain transport compartment can effectively improve the problem of the local temperature of the compartment being too low when the air is exchanged and the temperature is adjusted between compartments.

[0044] In some embodiments, the heat conductive member 2 can be extended along the extension direction of the air supply channel 10, such as at least the side of the second side heat conductive member facing the air supply channel 10 is extended along the air supply channel 10, so that heat is evenly exchanged along the extension direction in the air supply channel 10, and there is a longer path for heat exchange, so as to better improve the temperature of the air body in the air supply channel 10. Of course, further, the side of the first side heat conductive member facing the return air channel 20 can also be extended along the return air channel 20, so that heat is evenly exchanged along the extension direction in the return air channel 20. Similarly, there can be a longer path for heat exchange. Generally speaking, the heat conductive member 2 can include a first rod member located in the return air channel 20 as a first side heat conductive member; and / or the heat conductive member 2 can include a second rod member located in the air supply channel 10 as a second side heat conductive member. When the first rod and the second rod are provided at the same time, a heat-conducting rod can be further provided between the first rod and the second rod, and the two ends of the heat-conducting rod are in heat-conducting contact with the first rod and the second rod respectively; of course, a plurality of heat-conducting rods can be evenly distributed in the extending direction of the second rod. Of course, the specific structure of the heat-conducting member 2 can also be provided as required.

[0045] In some embodiments, at least one ventilation channel may be provided, and the heat conductive member 2 may be located in the ventilation channel to laterally separate the ventilation channel into an air supply channel 10 and an air return channel 20. That is, the heat conductive member 2 serves not only as a heat conductive structure but also as a channel isolation structure. The air supply channel 10 and the air return channel 20 are arranged close to each other to make the structure more compact, and the partition between the two is directly used as the heat conductive member 2, which not only meets the heat conductive requirements, but also has a good extension in the extension direction of the air supply channel 10, and has more heat exchange surfaces, so as to better meet the heating requirements, and at the same time, the structure is simple and the manufacturing method is simple.

[0046] The lateral direction refers to the direction perpendicular to the extension direction of the air supply channel 10. At this time, the air supply channel 10 and the return air channel 20 can be arranged in a winding form so that there is a sufficient heat exchange path within a limited length. The lateral separation has at least two forms: one is that the air supply channel 10 and the return air channel 20 are arranged in parallel horizontally; the other is that the air supply channel 10 and the return air channel 20 are in a sleeve relationship, and the heat conductor 2 is a pipe, a round pipe or a square pipe or other shape pipe. At this time, the inner cavity of the pipe serves as one of the air supply channel 10 and the return air channel 20; and the pipe is inserted into the ventilation channel; an annular cavity is formed between the outer wall of the pipe and the wall of the ventilation channel to serve as the other of the air supply channel 10 and the return air channel 20.

[0047] In some embodiments, the heat conducting member 2 can be arranged such that: one edge of one side is connected to the channel wall of one side of the ventilation channel, and the two sides are sealed; the other edge of the other side is connected to the channel wall of the other side of the ventilation channel, and the two sides are sealed. The ventilation channel is laterally divided into the air supply channel 10 and the return air channel 20. Compared with the embracing separation, the lateral parallel method can facilitate the fixing of the heat conducting member 2 therein.

[0048] In some embodiments, in order to form the above-mentioned ventilation channel, or the return air channel 20 and the air supply channel 10, they can be formed by pipe fittings, such as setting two pipe fittings so that the pipe cavities are the return air channel 20 and the air supply channel 10. Of course, it is also possible that at least one of the return air channel 20 and the air supply channel 10 is formed by enclosing a surrounding member 3 and the inner wall of the compartment.

[0049] In some embodiments, enclosures 3 may be included, and ventilation channels may be enclosed by enclosures 3. Specifically, enclosures 3 may be matched with the compartment to enclose the ventilation channels. Furthermore, air supply channels 10 and return air channels 20 may be separated in the ventilation channels by heat conducting members 2. It should be noted that enclosures 3 may be arranged at the corners of the compartment to enclose the ventilation channels with the walls on both sides of the corners of the compartment. Enclosures 3 may also be arranged at the wall of one side of the compartment to enclose the ventilation channels with only the inner wall of one side of the compartment, such as the inner wall of the top side or the side wall 400 on the left and right sides.

[0050] In some embodiments, one end of the enclosure 3 can be extended to the first compartment 100, and the other end can be extended to the second compartment 200; and the enclosure 3 is arranged at the inner corner of the cold chain transport compartment, and one side edge of the enclosure 3 is connected to the wall on one side of the inner corner, and the other side edge is connected to the wall on the other side of the inner corner. It should be noted that the inner corner refers to the angle where the two inner wall surfaces of the compartment intersect, such as the inner corner at the junction between the top wall 100 and the side wall 400. By setting the inner corner, the use of the enclosure 3 can be better saved, and the occupation of the compartment space can be better avoided. It should be noted that, as mentioned above, the ventilation passage can also be square or circular in cross section, and of course it can also be other shapes, such as a ventilation passage with a triangular or rectangular cross section surrounded by the enclosure 3.

[0051] In some embodiments, the first side of the two sides of the heat conductor 2 that are far away from each other can be connected to the corner inside the compartment, and the second side can be connected to the enclosure 3. This installation method can facilitate the installation of the heat conductor 2 and reduce the trouble of installation. It should be noted that the first side is connected to the corner inside the compartment, which can be a simple overlap relationship or a fixed method. In order to facilitate installation, bonding can be used because the force here is just the force in the abutment direction. The connection between the second side and the enclosure 3 can be a fixed connection or a simple abutment relationship. In practical applications, it can be set as needed. By connecting the first side to the compartment and the second side to the enclosure 3, the ventilation channel can be better separated to better guide the flow of wind.

[0052] In some embodiments, the side of the second side away from the air supply channel 10 can be made to abut against the enclosure 3. In practical applications, the wind pressure of the air supply channel 10 is generally higher than the wind pressure of the return air channel 20. Under the action of the wind pressure difference, the heat conducting member 2 tends to move toward the return air channel 20. At this time, the wind pressure difference can act on the second side, so that the second side can better abut against the enclosure 3 to achieve a better fixing effect. At this time, a sealing member can be added between the two to further reduce the flow of wind between the air supply channel 10 and the return air channel 20.

[0053] In some embodiments, of course, the two side edges of the heat conductor 2 that are far away from each other can be connected to the enclosure 3 or connected to the inner wall surface of the compartment. In this case, the heat conductor 2 can be a flat plate structure or a curved plate. For example, the heat conductor 2 can be bent into a curved plate so that the two side edges are connected to the enclosure 3, or the heat conductor 2 and the enclosure 3 can be arranged in parallel, and the two side edges of the heat conductor 2 that are far away from each other are respectively connected to the wall surfaces on both sides of the inner corner. Specifically, the structure of the heat conductor 2 can be set as needed.

[0054] In some embodiments, the enclosure 3 can be a plate, or a flat plate, and can be matched with the inner corners to surround and form a triangular ventilation channel. In this case, the first side of the two sides of the heat conductive member 2 that are separated from each other is connected to the inner corner, and the second side is connected to the enclosure 3. In this case, the heat conductive member 2 can further divide the triangular ventilation channel into two triangular channels, which are used as the air supply channel 10 and the return air channel 20 respectively.

[0055] In some embodiments, the enclosure 3 may be an L-shaped member, so as to be arranged at the inner corners, so as to surround and form a rectangular ventilation channel; in this case, the first side of the two sides of the heat-conducting member 2 that are far away from each other is connected to the inner corners, and the second side is connected to the enclosure 3; then the ventilation channel is divided into two triangular channels, or two trapezoidal channels, or one trapezoidal channel and one triangular channel, which are respectively used as the air supply channel 10 and the air return channel 20. Of course, the enclosure 3 may also be U-shaped, so as to be arranged on the inner wall surface of one side of the compartment, so as to surround and form a rectangular ventilation channel; in this case, the first side of the two sides of the heat-conducting member 2 that are far away from each other is connected to the inner corners, and the second side is connected to the enclosure 3; then the ventilation channel is divided into two rectangular channels.

[0056] In some embodiments, the heat conducting plate can be a wave plate, that is, the cross section in a certain direction is wavy, which can be a square wave or a sine wave, or an irregular wave structure. The use of a wave structure can well increase the contact surface to achieve a good heat exchange effect. Specifically, the cross section can be wavy along the parallel direction of the first side and the second side, or it can be wavy in the extension direction of the first side. The wave direction is preferably consistent with the air supply direction of the air supply channel 10, and the flow of the wind body will be affected by the wave structure, which not only improves the contact effect, but also can achieve turbulence to better achieve heat exchange. It should be noted that the wave direction refers to the parallel direction of the wave structure, that is, the extension direction of the wave line.

[0057] In some embodiments, the upper channel of the heat conducting member 2 can be the air supply channel 10, and the lower channel can be the return air channel 20. Of course, in this way, the heat conducting member 2 can be placed horizontally or tilted. When tilted, the side surface of the side tilted upward faces the air supply channel 10, and the side surface of the side tilted downward faces the return air channel 20. Of course, in some other embodiments, the return air channel 20 can be on the top and the air supply channel 10 can be on the bottom.

[0058] In some embodiments, such as the above-mentioned scheme, the upper channel is the supply air channel 10 and the lower channel is the return air channel 20. This will cause the upper air body of the gas in the return air channel 20 to settle after absorbing heat, and will cause the hot gas to float. This can better achieve the heating of the air body in the supply air channel 10 by the air body in the return air channel 20.

[0059] In some embodiments, in order to facilitate the arrangement of the first air outlet 10-1 and the second air inlet 20-2, so as to better communicate gas with the second compartment 200 in the extension direction, the first air outlet 10-1 can be provided in the portion of the enclosure 3 corresponding to the air supply channel 10; similarly, the second air inlet 20-2 can be provided in the portion of the enclosure 3 corresponding to the air return channel 20. In the first compartment 100, the end surface of the enclosure 3 can be opened, and the heat conducting member 2 can be extended to the end surface to form the second air outlet 20-1 and the first air inlet 10-2 respectively.

[0060] In some embodiments, the first air outlet 10-1 can be located on the side of the enclosure 3 close to the top wall 300 of the compartment; the second air inlet 20-2 can be located on the side wall 400 of the enclosure 3 close to the adjacent side of the compartment, where the side wall 400 refers to the side wall 400 on the left and right side, which is generally a vertical wall. The first air outlet 10-1 is arranged on the side of the enclosure 3 close to the top wall 300 of the compartment, so that the position of the first air outlet 10-1 can be higher. This is because when the cold chain transport compartment is in use, space is generally reserved at the top, and raising the position of the first air outlet 10-1 can make the first air outlet 10-1 outlet flow better dispersed in the top space. Of course, the first air outlet 10-1 can blow horizontally, horizontally upward, or horizontally downward. The horizontal direction is tilted upward to blow toward the inner wall surface at the top of the compartment, so that the temperature of the inner wall surface at the top of the compartment can be utilized. It should be noted that, in order to better realize the flow of wind in the second compartment 200, the first air outlet 10-1 can be oriented horizontally, that is, left and right, horizontally, obliquely upward or obliquely downward; and the second air inlet 20-2 is downward, so that the wind can realize annular flow in the second compartment 200. Specifically, the first air outlet 10-1 can be extended in the extension direction of the air supply channel 10 to form a long strip, and / or, a plurality of first air outlets 10-1 can be arranged in the extension direction of the air supply channel 10. The extension direction of the air supply channel 10 is generally the parallel direction of the first compartment 100 and the second compartment 200, and the general parallel direction is the front-to-back direction. The end of the air supply channel 10 generally extends to the end of the second compartment 200 away from the first compartment 100. Similarly, the second air inlet 20-2 can also be extended in the extension direction of the return air channel 20 to form a long strip, and / or, a plurality of second air inlets 20-2 can be arranged in the extension direction of the return air channel 20. Of course, the first air outlet 10-1 and the second air inlet 20-2 can be aligned and have the same length and shape. When there are multiple air outlets 10-1 and 20-2, they can be aligned one by one to ensure better formation of an annular flow air body.

[0061] In some embodiments, as described above, in order to promote the flow of air, a fan 4 is generally provided. Generally, the fan 4 only needs to be provided at one of the air supply channel 10 and the air return channel 20. Of course, in addition to the fan 4, other gas-driven devices, such as a bellows, may also be used.

[0062] In some embodiments, as described above, a fan 4 is provided at one end of the ventilation passage located in the first compartment 100. The fan 4 is provided in the first compartment 100 so that it can be closer to the refrigeration device 1 and can be wired together with the refrigeration device 1, especially the power supply line and the signal control line.

[0063] In some embodiments, the air inlet and the air outlet of the fan 4 may be oriented toward two sides away from each other. Alternatively, the air inlet of the fan 4 may be oriented horizontally and the air inlet may be oriented downward, in which case the axis of the fan 4 may be vertically arranged.

[0064] In some embodiments, the first air inlet 10-2 can be formed at the end face of the enclosure 3 and the end of the enclosure 3 is abutted against the air outlet side of the fan 4 and connected to the air outlet of the fan 4. At this time, the air outlet direction of the fan 4 is consistent with the extension direction of the ventilation channel, that is, consistent with the air supply direction of the air supply channel 10, so as to better introduce wind. The end face of the enclosure 3 refers to the end face at one end of the extension direction, that is, the edge of the end face of the enclosure 3 located in the first compartment 100, and the edge of the end face of the heat conducting member 2 and the inner wall of the compartment surround a first air inlet 10-2, and the edge of the end face of the enclosure 3 located in the second compartment 200 and the inner wall of the compartment are blocked by a blocking plate.

[0065] In some embodiments, the air inlet of the fan 4 can be set downward, and at this time, the second air outlet 20-1 is opened at the end of the enclosure 3 and is set downward. At the same time, the end of the channel cavity where the return air channel 20 is located is blocked by the fan 4 casing to serve as an end wall.

[0066] In some embodiments, it is considered that the air supply channel 10 and the return air channel 20 will have a certain extension in the first compartment 100, so as to ensure that there are more heat exchange paths. In the first compartment 100, the enclosure 3 is not completely heat-insulated. Here, it is preferred that the enclosure 3 has a heat-insulating layer in the part of the first compartment 100, so that the ventilation channel does not exchange heat with the first compartment 100 through the enclosure 3 as much as possible. This is because the wind temperature in the air supply channel 10 and the return air channel 20 is higher than the wind temperature in the first compartment 100. Through the above arrangement, the return air channel 20 can better heat the wind body in the air supply channel 10 at the first compartment 100. Specifically, a sponge layer can be attached to the inner or outer surface of the enclosure 3 as a heat-insulating layer, and of course, the inner or outer surface of the enclosure 3 can also be sprayed with paint to achieve heat insulation.

[0067] In some embodiments, the thermal conductivity of the portion of the enclosure 3 located in the first compartment 100 may be lower than that of the portion located in the second compartment 200. As described above, the portion of the enclosure 3 located in the first compartment 100 may have a heat insulating layer.

[0068] In some embodiments, in order to achieve better heat conduction, it is preferred that the thermal conductivity of the heat conducting member 2 is higher than that of the surrounding member 3. This can be achieved by using different materials, so that the thermal conductivity of the heat conducting member 2 is higher than that of the surrounding member 3. Of course, the heat conducting member 2 and the surrounding member 3 can also be made of the same material, but the thickness of the heat conducting member 2 is thinner than that of the surrounding member 3, so that the heat conduction is faster.

[0069] In some embodiments, an air duct device for a cold chain transport compartment is provided, which can be applied to the above-mentioned temperature control system, or can be applied to a temperature control system not provided with a refrigeration device 1. Specifically, the air duct device can include the enclosure 3 mentioned in any of the above-mentioned embodiments, the heat conducting member 2 mentioned in any of the above-mentioned embodiments, or the fan 4 mentioned in any of the above-mentioned embodiments.

[0070] The enclosure 3 is plate-shaped and tilted so that the upper edge is used to connect to the top wall 300 of the compartment, and the lower edge is used to connect to the side wall of the compartment in the left and right directions, so as to surround and form a triangular ventilation passage. For easy installation, the upper edge of the enclosure 3 can form a first folded edge portion 3-1 to abut against the top wall 300 of the compartment, and rivet, weld or bond them together. The lower edge of the enclosure 3 can form a second folded edge portion 3-2 to abut against the side wall of the compartment in the left and right directions, and rivet, weld or bond them together. At this time, the first folded edge portion 3-1 and the second folded edge portion 3-2 are in a vertical state.

[0071] The longitudinal direction of the heat-conducting member 2 is consistent with the longitudinal direction of the enclosure 3, and it is plate-shaped and inclined. The upper edge is aligned with the upper edge of the enclosure 3 in the vertical direction of the compartment and / or aligned with the lower edge of the enclosure 3 in the left-right direction of the compartment, so that it is installed on the same inner wall surface of the compartment with the upper edge of the enclosure 3, or installed on the same inner wall surface of the compartment with the lower edge of the enclosure 3, or directly installed on the inner corner. The lower edge of the heat-conducting member 2 abuts against the middle of the enclosure 3 to separate the triangular area surrounded by the enclosure 3 into an air supply channel 10 and a return air channel 20, and both ends of the air supply channel 10 and both ends of the return air channel 20 are provided with vents to respectively form the above-mentioned first air outlet 10-1, first air inlet 10-2, second air outlet 20-1 and second air inlet 20-2. The specific vent formation method can refer to the above-mentioned embodiment. Specifically, the third folded edge portion 2-1 can be formed on the upper side of the heat-conducting member 2, and bent downward to be arranged coplanar with the second folded edge portion 3-2, and installed on the same inner wall surface of the compartment, wherein the second folded edge portion 3-2 can also be bent downward. The fourth folded edge portion 2-2 is formed on the lower side of the heat-conducting member 2 to abut against the upper surface of the enclosure 3, and a sealing gasket can be added in between, wherein the fourth folded edge portion 2-2 is preferably tilted downward. At this time, the upper side channel of the heat-conducting member 2 is the air supply channel 10, so that it is subjected to downward pressure, which is transmitted to the enclosure 3 through the fourth folded edge portion 2-2, so that it is more closely attached to the enclosure 3, just like the side of the second side of the heat-conducting member 2 away from the air supply channel 10 in the above embodiment is against the enclosure 3. The heat-conducting member 2 exchanges heat between the air supply channel 10 and the return air channel 20 to fully improve the heat exchange efficiency.

[0072] The fan 4 is disposed at one end of the enclosure 3, and the enclosure 3 and the heat conducting member 2 are both mounted on the side wall of the fan 4, and the fan 4 is used to accelerate the flow of wind in the air supply channel 10. When installed in the compartment, the enclosure 3, the heat conducting member 2 and the fan 4 all need to be directly connected to the compartment.

[0073] Based on the temperature control system provided in the above embodiments, the utility model also provides a cold chain transport compartment, which includes any one of the temperature control systems in the above embodiments, and also includes a compartment, wherein the compartment is separated into a first compartment 100 and a second compartment 200 that are isolated from each other along the front-to-back direction.

Alternatively, as described in the above embodiments, the enclosure 3 and the heat conducting member 2 can be made to span between the first compartment 100 and the second compartment 200 to transfer the wind body, the air supply channel 10 is used to send the wind body from the first compartment 100 to the second compartment 200, and the return air channel 20 is used to guide the wind body from the second compartment 200 back to the first compartment 100.
