[0002] Refrigerated trucks are closed van transport vehicles used to transport frozen or fresh goods. They are special refrigerated transport vehicles equipped with a refrigeration unit and a polyurethane insulated compartment. They are commonly used to transport frozen foods (refrigerated trucks), dairy products (dairy transport trucks), vegetables and fruits (fresh goods transport trucks), vaccines and medicines.

[0003] For the transport of pharmaceuticals at a constant temperature, the industry currently relies on specialized refrigerated pharmaceutical transport vehicles. Existing refrigerated pharmaceutical transport vehicles often employ thermal insulation panels or magnetic curtains as protective measures for multi-point delivery, but these measures are ineffective. The thermal insulation panels are thick and heavy, and they move and float during unloading, allowing large amounts of air to flow into the vehicle compartment. Furthermore, when the magnetic curtain is opened again to retrieve the goods, it can also cause a large amount of air to flow into the vehicle compartment due to problems such as unstable magnetic adhesion, loose sealing, or excessive opening. This can cause the storage space to lose temperature, increasing the risk of thermal dehumidification in the pharmaceutical storage area. Utility Model Content

[0037] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0038] Example 1

[0039] See Figures 1 to 5 The pharmaceutical transport refrigerated truck provided in this embodiment includes a vehicle head 100 and a vehicle compartment 200. The vehicle head 100 has a cab.

[0040] The compartment 200 is provided with a refrigerator, which includes a storage area 210 and a transition area 220. The storage area 210 is provided at the end of the compartment 200 close to the front 100, and the transition area 220 is provided at the end of the compartment 200 away from the front 100. A door 230 is provided at the end of the transition area 220 away from the storage area 210. A refrigeration unit 211 is provided in the storage area 210. A partition and insulation unit 240 is provided between the storage area 210 and the transition area 220, and at the junction of the door 230 and the storage area 210. The partition and insulation unit 240 can be opened and closed to connect or separate the storage area 210 and the transition area 220. The refrigerator is provided with an air inlet 251 of the air inlet 250 provided in the storage area 210, and an air outlet 252 provided in the transition area 220.

[0041] Specifically, the partition and insulation component 240 in this embodiment divides the compartment 200 into a storage area 210 and a transition area 220. The refrigeration component 211 in the storage area 210 can create a constant temperature environment in the storage area 210 to store and transport medicines that need to be kept at a constant temperature. The partition and insulation component 240 between the transition area 220 and the vehicle door 230 can prevent the vehicle door 230 from exchanging heat with the transition area 220, and the temperature in the transition area 220 is not much different from the temperature of the storage area 210.

[0042] When transporting medicines from the compartment 200 to outside the compartment 200, the medicines to be transported can be first transported from the storage area 210 to the transition area 220. The air induced component 250 can guide the airflow from the storage area 210 to the transition area 220, so that the temperature of the transition area 220 is the same as the temperature of the storage area 210. The insulating component 240 separating the transition area 220 and the door 230 can prevent the transition area 220 from exchanging heat with the door 230, resulting in temperature loss in the transition area 220, thereby ensuring that the quality of medicines temporarily placed in the transition area 220 will not change due to temperature loss in the transition area 220.

[0043] After the medicines are transported to the transition area 220, the partition and insulation member 240 between the transition area 220 and the storage area 210 is closed, and then the door 230 is opened to move the medicines in the transition area 220 out of the vehicle compartment 200. During the process of transporting the medicines from the transition area 220 out of the vehicle compartment 200, the partition and insulation member 240 between the storage area 210 and the transition area 220 can form a partition between the storage area 210 and the transition area 220, preventing air from entering the storage area 210 from the transition area 220 after the door 230 is opened, causing air to flow into the storage area 210 and causing the storage area 210 to lose temperature.

[0044] In this embodiment, the air induction assembly 250 includes an air induction trough and an air induction fan. The air inlet 251 of the air induction trough is located at the top of the refrigerator compartment, and the air inlet 251 of the air induction trough is located in the storage area 210, and the air outlet 252 of the air induction trough is located in the transition area 220. The air induction fan is located at the air outlet 252 of the air induction trough, and the air outlet direction of the air induction fan is toward the transition area 220.

[0045] The induced draft fan blows the gas in the induced draft trough into the transition zone 220. The air pressure in the induced draft trough is lower than the air pressure in the storage area 210. The cold air in the storage area 210 enters the induced draft trough through the air inlet 251 of the induced draft trough, thereby forming an air flow transport, so that the temperature of the transition zone 220 can be the same as the temperature of the storage area 210, thereby ensuring that the quality of the medicines temporarily stored in the transition zone 220 will not change due to the temperature drop of the storage environment.

[0046] In this embodiment, the air induction duct includes a duct plate, which is provided at a corner of the top of the refrigeration chamber, and the duct plate, the top wall, and the side walls of the refrigeration chamber together form a triangular air induction duct.

[0047] Specifically, there are two trough plates in this embodiment, and the two trough plates are respectively arranged at the side edges of the top surface of the cold storage chamber. The two trough plates and the top wall and side wall of the cold storage chamber are combined to form two relatively stable triangular air ducts. The two triangular air ducts are both equipped with air duct fans, thereby realizing dual-duct delivery of cold air.

[0048] In this embodiment, the pharmaceutical transport refrigerated vehicle further includes a water collection trough 300 and a diversion trough 400. The water collection trough 300 is disposed around the outside of the bottom wall of the refrigeration compartment, connecting to the front and side walls of the refrigeration compartment. The diversion trough 400 is disposed on the front, side, and bottom walls of the refrigeration compartment. Multiple diversion troughs 400 are provided, spaced apart on the front, side, and bottom walls of the refrigeration compartment.

[0049] Specifically, when transporting medicines to the cold storage compartment, the vehicle door 230 must be fully opened for a prolonged period of time. Furthermore, the temperature of the medicines may fluctuate above the room temperature, which can cause temporary temperature fluctuations within the cold storage compartment. After the cold storage compartment is closed to form a sealed space, water droplets are easily condensed on the interior walls due to the exchange of hot and cold air. If excessive water droplets accumulate on the outer packaging of the medicines, the packaging may be damaged, resulting in moisture damage to the medicines.

[0050] The water collection trough 300 in this embodiment is arranged on the bottom wall of the cold storage chamber. When water droplets condense in the air in the cold storage chamber, the water droplets gather on the front wall and side walls of the cold storage chamber. After the water droplets accumulate, under the action of their own weight, they flow along the front wall and side walls to the bottom wall of the cold storage chamber and enter the water collection trough 300 to gather. Since the water collection trough 300 is a lower groove body, the condensed water in the water collection trough 300 will not wet the bottom of the medicine, thereby effectively preventing the condensed water from gathering on the bottom wall of the cold storage chamber and contacting the medicine, causing the medicine to be wet.

[0051] In addition, when medicines are densely stacked in the cold storage room, they fit closely together, making it difficult for cold air to enter between the stacked medicines, which can easily cause the medicines in the central area to lose temperature. In this embodiment, the guide groove 400 located on the bottom wall of the cold storage room is provided with notches at both ends. Cold air can flow into the guide groove 400 on the bottom wall of the cold storage room through the notches at both ends and flow along the guide groove 400 to various parts of the bottom wall of the cold storage room, thereby cooling the stacked medicines and avoiding the situation where cold air cannot enter the stacked medicines due to the medicines being too densely stacked, resulting in the quality of the stacked medicines changing due to uneven temperature.

[0052] In this embodiment, the guide groove 400 is buckled on the front wall, side wall and bottom wall of the refrigerating chamber; the guide groove 400 and the front wall, side wall and bottom wall of the refrigerating chamber are combined to form a groove body with two ends open.

[0053] The openings of the guide groove 400 located on the front wall and the side wall of the refrigeration chamber are arranged at the top and bottom ends of the guide groove 400, which can facilitate the flow and storage of cold air.

[0054] Moreover, the guide groove 400 in this embodiment is an outwardly convex groove body, and a plurality of guide grooves 400 are arranged at intervals on the side wall of the cold storage room. When the medicines are stored in the cold storage room, the condensed water on the side wall of the cold storage room flows down along the inner wall of the cold storage room into the water collecting groove 300, and the side surface of the medicine fits into the groove wall of the guide groove 400. The guide groove 400 can separate the side wall of the medicine from the side wall of the cold storage room. The side surface of the medicine contacts the condensed water on the inner wall of the cold storage room, causing the medicine to be wet.

[0055] In this embodiment, the guide groove 400 includes a first groove body provided on the front wall, a second groove body provided on the side wall, and a third groove body provided on the bottom wall.

[0056] Specifically, in this embodiment, the first trough is 10 cm wide, 10 cm deep, and 180 cm long, with the distance between adjacent first troughs being 30 cm. The second trough is 5 cm wide, 5 cm deep, and 180 cm long, with the distance between adjacent second troughs being 40 cm. The third trough is 3 cm wide and 5 cm deep, with the front and rear ends of the third trough 5 cm apart from the front and rear ends of the refrigeration compartment, respectively, and the distance between adjacent third troughs being 2 cm.

[0057] In this embodiment, a water outlet pipe 310 is provided at the bottom of the compartment 200. The top end of the water outlet pipe 310 is communicated with the plurality of water collecting tanks 300, and a switch valve is provided on the water outlet pipe 310.

[0058] Specifically, to facilitate the collection and discharge of condensed water, in this embodiment, the water collecting tank 300 on the bottom wall of the transition zone 220 near the vehicle door 230 is set as a drainage tank 320, and the drainage tank 320 is connected to the water collecting tank 300. The mouth of the water outlet pipe 310 is set at the bottom of the drainage tank 320, thereby realizing the connection between the water outlet pipe 310 and all water collecting tanks 300.

[0059] In addition, the switch valve can realize the opening and closing of the water outlet pipe 310 to ensure that the refrigeration chamber can be in a sealed state when no water is discharged, thereby preventing air from entering the refrigeration chamber along the water pipe and causing heat loss in the refrigeration chamber.

[0060] In this embodiment, the guide groove 400 is buckled on the side wall of the refrigeration chamber, and the guide groove 400 and the side wall of the refrigeration chamber are combined to form a groove body with two ends open.

[0061] Specifically, the guide groove 400 in this embodiment is an outwardly convex groove body, and multiple guide grooves 400 are arranged at intervals on the front wall and side walls of the cold storage room. When the medicines are stored in the cold storage room, the condensed water on the side walls of the cold storage room flows down along the inner wall of the cold storage room into the water collecting groove 300, and the side of the medicine fits into the groove wall of the guide groove 400. The guide groove 400 can separate the side wall of the medicine from the side wall of the cold storage room, preventing the side of the medicine from contacting the condensed water on the inner wall of the cold storage room, causing moisture damage to the medicine.

[0062] Example 2

[0063] In this embodiment, the pharmaceutical transport refrigerated vehicle further includes a heat conducting trough 500. The refrigeration element 211 has multiple cold air outlets. The heat conducting trough 500 has an air inlet and an air outlet. The air inlet is connected to one or more cold air outlets. The plurality of air outlets are provided on the bottom wall of the refrigeration compartment and are spaced apart along the length of the bottom wall.

[0064] The heat conduction groove 500 enables the conduction and transmission of cold air. After the cold air generated by the refrigeration element 211 is discharged through multiple cold air outlets, the heat conduction groove 500 in this embodiment is connected to one of the cold air outlets. After entering the heat conduction groove 500, the cold air discharged from the cold air outlet is discharged through the multiple air outlets 252 to various locations in the refrigeration compartment, thereby ensuring uniform cooling of the refrigeration compartment and accelerating the cooling of locations in the refrigeration compartment that are farther away from the refrigeration element 211.

[0065] In this embodiment, the heat conduction groove 500 includes a connecting section 510 and an air outlet section 520. The refrigeration element 211 is located at the top of the side wall of the refrigeration compartment near the front of the vehicle 100. The connecting section 510 is located on the side wall of the refrigeration compartment where the refrigeration element 211 is located, and the top of the connecting section 510 is connected to the cold air outlet of the refrigeration element 211. The air outlet section 520 is located on the bottom wall of the refrigeration compartment. There are multiple air outlet sections 520, each of which is connected to the connecting section 510, and multiple air outlet holes are provided on each of the air outlet sections 520.

[0066] Specifically, one end of the connecting section 510 in this embodiment is connected to the cold air outlet of the refrigeration component 211 , and the other end is connected to multiple air outlet sections 520 , so that the cold air discharged from the cold air outlet can enter each air outlet section 520 .

[0067] Furthermore, the positions of the air outlet holes on the multiple air outlet sections 520 in this embodiment are all different, thereby achieving exhaust at multiple positions, and further achieving cooling at multiple positions in the refrigeration chamber.

[0068] Specifically, there are three air outlet sections 520 in this embodiment, and the air outlets 252 on the three air outlet sections 520 are respectively located at the front, middle and rear positions of the storage area 210. Under this structure, the front, middle and rear positions of the storage area 210 can be cooled simultaneously.

[0069] In addition, a valve body is also provided on the heat conduction groove 500 in this embodiment. When there are fewer goods and medicines in the cold storage room, the goods can be placed in an area close to the refrigeration component 211 and the valve body can be closed to make the heat conduction groove 500 closed. The cold air generated by the refrigeration component 211 can be concentrated and discharged in the cargo placement area close to the refrigeration component 211 to avoid the loss of cold air.

[0070] Furthermore, when storing and transporting bulk goods in naked packages, the bulk goods can be placed at positions on the bottom wall of the refrigeration chamber where no air outlet 252 is provided, to prevent the goods from being directly blown by cold air or covering the air outlet 252 .

[0071] As a feasible method, when transporting a large amount of goods, it is inevitable that the goods will be placed on the air outlet 252. In this case, a pallet can be used to support the goods. When loading the goods into the cold storage room, the goods are first placed on the pallet under the vehicle and secured. Then, the pallet loaded with goods is transported to the cold storage room. Therefore, there is a certain gap between the bottom wall of the pallet and the air outlet 252, which will not cause the air outlet 252 to be blocked and prevent air from being discharged. In addition, a barrier can be formed between the goods and the air outlet 252 to prevent the goods from being directly blown away.

[0072] Correspondingly, in this embodiment, prompt lines are provided on the front wall and side walls of the refrigeration chamber. The prompt lines are set at a certain interval below the refrigeration unit 211 to indicate the stacking height of the goods, so as to avoid the stacking height being too high affecting the air circulation inside the car and the cold air discharged from the refrigeration unit 211 directly blowing on the goods.

[0073] In this embodiment, the partition and insulation element 240 is a coated door curtain. The coated door curtain comprises a coated fabric cover and an insulating core within the coated fabric cover. In this embodiment, two coated door curtains are provided. The top of the coated door curtain is fixed to a strip of metal track (not a slide). Magnetic elements are located on both sides and at the overlapping center of the coated door curtain. Two coated door curtains are stacked together, with an overlap of greater than or equal to 20 cm. The removable magnetic element separates the storage area 210 from the transition area 220.

[0074] Specifically, the coated door curtain in this embodiment is a PU protective door curtain. The coating fabric of the PU protective door curtain is a high-strength fiber PU coated cloth. The total compacted thickness of the PU protective door curtain is 3cm, and the finished coating thickness is no less than 0.5mm. This structure provides strong wear resistance, a wide temperature range, and excellent heat and cold insulation.

[0075] In addition, magnetic parts with opposite magnetic properties are provided on both sides of the coated door curtain in this embodiment. The coated door curtain is abutted and fitted with the side wall of the cold storage chamber through the magnetic structure. Adjacent coated door curtains can also be abutted and fitted by magnetic attraction, further ensuring the cold and heat insulation effect of the coated door curtain.

[0076] Example 3

[0077] In this embodiment, uniform temperature sensing probes 600 are provided on the side walls of the transition zone 220 and the storage area 210, and the temperature sensing probes 600 are respectively provided at different positions of the storage area 210 and the transition zone 220, thereby realizing temperature detection at different positions of the storage area 210 and the transition zone 220. The ambient temperature of the transition zone 220 and the storage area 210 can be judged according to the detection data of the temperature sensing probes 600, thereby adjusting the refrigeration temperature of the cold parts, realizing accurate temperature control of the transition zone 220 and the storage area 210, and avoiding the temperature abnormality in the refrigerated room from being detected and adjusted in time.

[0078] In addition, in this embodiment, a controller is provided in the cab, which can locate the vehicle's position on the way and receive and upload temperature data in the cold storage room. In addition, in this embodiment, the temperature probes 600 at the cold spot (near the refrigerator) and the hot spot (near the vehicle door) in the cold storage room are high-precision temperature sensors.

[0079] The temperature probe 600 and high-precision temperature sensors enable real-time, 24 / 7 monitoring, accurately capturing and recording changes in the cold storage room's ambient temperature, and transmitting the collected data to the cloud for storage and analysis. Specifically, the controller in this embodiment is a vehicle-mounted Beidou terminal, or Beidou all-in-one device. Managers can access real-time temperature data, historical data, driving trajectories, and other information online anytime, anywhere. Upper and lower thresholds for temperature loss warnings can be set in the system's backend. When the cold storage room temperature reaches these thresholds, an SMS or WeChat alert is sent, minimizing the risk of medication dehumidification.
