Description

Technical Field

[0002] Medical transfer boxes are mainly used for the storage and transportation of medical supplies such as biological preparations, vaccines, and medicines. Different types of medical transfer boxes are required for different requirements of medical supplies. Generally, medical transfer boxes can be divided into frozen type, refrigerated type, and normal temperature type to meet the needs of various types of medical supplies. At present, no matter what kind of medical transfer box is used, additional constant temperature equipment or means are usually used to maintain the internal constant temperature conditions.

[0059] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

Therefore, the above terms should not be understood as limiting the present invention.

[0061] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not therefore limited to the following embodiments.

[0062] Combination Figure 1 and Figure 2As shown, according to one embodiment of the present invention, a portable heat preservation transfer box of the present invention comprises: a box body 1, a box cover 2, a lithium battery power source 3 installed in the box body 1, a constant temperature preservation unit 4 and a control unit 5. In this embodiment, the box cover 2 is connected to the box body 1 in an openable and closable manner. In this embodiment, the constant temperature preservation unit 4 comprises: an inner liner 41, a constant temperature device 42 connected to the inner liner 41 on the left side of the box body, and a heat dissipation component 43 connected to the constant temperature device 42. In this embodiment, the cross-section of the inner liner 41 is a rectangular hollow cylindrical structure. The heat dissipation component 43 and the lithium battery power source 3 are respectively located on the left and right sides of the inner liner 41, and the control unit 5 is located on the front side of the inner liner 41 (i.e., the third side of the inner liner 41).

[0063] like Figure 2 As shown, according to one embodiment of the present invention, the inner liner 41 is a hollow cylinder with one end open. In this embodiment, the thermostat 42 is installed on one side of the inner liner 41 in contact with the inner liner 41. In this embodiment, at least one thermostat 42 is provided on one side of the inner liner 41, that is, the thermostat 42 can be set to one, two, three or more. When there are multiple thermostats 42, multiple thermostats 42 can be set at intervals. In this embodiment, two thermostats 42 are provided, and then on the side of the inner liner 41 along the height direction of the inner liner, the thermostats 42 are installed on the inner liner 41 at intervals, and the temperature control side of the thermostat 42 is in contact with the inner liner 42. In this embodiment, the thermostat 42 can be in direct contact with the inner liner 41, or a heat transfer layer (such as a heat-conducting silicone layer or a heat-conducting metal layer) is provided at the contact position to achieve stable heat exchange with the inner liner 41.

[0064] In this embodiment, the thermostat 42 is made of a semiconductor refrigeration structure. A heat dissipation component 43 is installed on the other side of the thermostat 42 to achieve rapid and stable heat dissipation of the thermostat 42 during the heat exchange process, thereby ensuring stable operation of the thermostat 42.

[0065] In this embodiment, the inner liner 41 is made of a material with good thermal conductivity, which can facilitate the heat exchange on the entire inner liner 41 at the contact position of the thermostat 42, thereby improving the overall constant temperature performance of the inner liner. For example, the inner liner 41 can be made of a metal material.

[0066] Combination Figure 2 , Figure 3 and Figure 4As shown, according to one embodiment of the present invention, the heat dissipation assembly 43 includes: a fin heat sink 431, and a heat dissipation fan 432 embedded in the fin heat sink 431. In this embodiment, the number of the heat dissipation fan 432 can be one or more (such as two, single, etc.), and the setting position can also be adjusted as needed. In this embodiment, the plane end of the fin heat sink 431 is connected to the thermostat 42, and the fin end of the fin heat sink 431 is surrounded by fins arranged at different heights to form an installation position 431a for accommodating the heat dissipation fan 432.

[0067] In this embodiment, the fins with higher height in the fin heat sink 431 are arranged around the cooling fan 432, and the fins with lower height are arranged below the cooling fan 432, so that a groove-shaped installation position 431a for installing the cooling fan 432 is surrounded by the fins with different heights. The cooling fan 432 and the fin heat sink can be fixed by using a threaded connector. In this embodiment, the fins with lower height and the fins with higher height can be independent of each other, or they can be formed into different heights by secondary processing on fins of the same height according to the shape of the cooling fan.

[0068] In this embodiment, the fins in the fin heat sink 431 are plate-shaped structures, which are arranged at equal intervals in the same direction on the fin heat sink 431. When the fins are long, notches can be provided on the fins to achieve segmentation of the long fins, which is beneficial to improving ventilation and heat dissipation of the fins.

[0069] According to one embodiment of the present invention, a strip-shaped heat dissipation protrusion having an angle with the fin (for example, 30°, 45°, 60°, 90°, etc.) can be selectively provided on the side surface of the fin in the fin heat sink 431, and the heat dissipation protrusion extends freely along the length direction of the fin, and a plurality of heat dissipation protrusions are provided at intervals in the height direction of the fin. In this embodiment, the inclination angles of two adjacent heat dissipation protrusions relative to the fin can be consistent or different. In this embodiment, the cross-sectional width of the heat dissipation protrusion gradually decreases in the direction away from the fin. In this embodiment, the heat dissipation protrusion provided on the side surface of the fin can be hollow, and the hollow portion thereof passes through the opposite ends of the heat dissipation protrusion along the length direction of the fin.

[0070] According to an embodiment of the present invention, the fin is provided with a hollow first heat dissipation channel, which runs through opposite ends of the fin along the length direction of the fin, and a plurality of the first heat dissipation channels are arranged at intervals in the height direction of the fin.

[0071] According to one embodiment of the present invention, the fin is provided with a hollow second heat dissipation channel, which extends in the fin along the height direction of the fin and cross-connects with the first heat dissipation channel arranged in the length direction to form a mesh heat dissipation channel structure, and a plurality of the second heat dissipation channels are arranged at intervals along the length direction of the fin.

[0072] Through the above-mentioned arrangement, a mesh-shaped hollow heat dissipation structure is arranged inside the fin, so that air flow can be generated inside the fin under the action of the heat exchange fan, effectively realizing synchronous heat dissipation inside and outside the fin, as well as in the length direction and height direction, effectively increasing the heat exchange efficiency inside the fin, greatly improving the heat dissipation effect of the present invention, and thus being beneficial to ensuring the stable operation of the constant temperature device 42 and eliminating the accumulation of internal heat.

[0073] Combination Figure 2 and Figure 5 As shown, according to one embodiment of the present invention, the heat dissipation assembly 43 further includes: a heat insulation plate 433 disposed at the plane end of the fin heat sink 431. In this embodiment, a connection channel 433a that runs through the body of the heat insulation plate 433 is disposed at a position corresponding to the thermostat 42. In this embodiment, opposite sides of the heat insulation plate 433 are respectively connected to the fin heat sink 431 and the thermostat 42. In this embodiment, heat exchange between the fin heat sink 431 and the thermostat 42 is achieved through the connection channel 433a disposed on the heat insulation plate 433.

[0074] In this embodiment, the connection channel 433a is filled with a heat conductive sheet 433a1. In this embodiment, one side of the heat conductive sheet 433a1 contacts the side of the thermostat 42, and the other side contacts the flat end of the fin heat sink 431. In this embodiment, the heat conductive sheet 433a1 can be made by filling the connection channel 433a with a heat conductive silicone material.

[0075] Through the above arrangement, by arranging a heat insulation board on one side of the fin heat sink in the heat dissipation assembly, the reverse transfer of heat on the fin heat sink can be effectively isolated, the heat dissipation efficiency of the fin heat sink is guaranteed, and thus it is beneficial to ensure the constant temperature effect of the present invention. In addition, by arranging a heat insulation board and connecting the fin heat sink and the constant temperature device through the heat insulation board, it is beneficial to the sealing isolation of the heat dissipation part and the constant temperature part, and effectively ensures the sealing and heat preservation performance of the present invention.

[0076] Through the above arrangement, by setting a connecting channel on the heat insulation board and filling the connecting channel with a heat conductive layer, the heat on the thermostatic device can be stably, quickly and effectively transferred to the finned heat sink through the connecting channel filled with the heat conductive layer, so as to facilitate the high heat dissipation rate of the finned heat sink to the thermostatic device. In addition, by adopting a filling method to set the heat conductive layer in the connecting channel, the segmentation sealing of the heat insulation board is further effectively guaranteed, which is beneficial to ensuring the sealing and heat preservation performance of the present invention.

[0077] Combination Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, according to one embodiment of the present invention, the box body 1 includes: a hollow shell 11, and a heat preservation layer 12 installed in the shell 11. In this embodiment, the shell 11 is a hollow rectangular box structure as a whole, and an opening 111 matching the cross-sectional shape of the inner tank 41 is provided on its upper end surface. In this embodiment, a heat dissipation component compartment 11a for installing a heat dissipation component 43 and a power supply compartment 11b for installing a lithium battery power supply 3 are provided on opposite sides of the length direction of the shell 11, as well as a heat dissipation hole plate 13 detachable from the heat dissipation component compartment 11a and a power supply compartment baffle 14 detachable from the power supply compartment 11b. In this embodiment, a through channel is provided on one side of the heat dissipation component compartment 11a adjacent to the heat preservation layer 12 corresponding to the thermostat 42, and the cross-sectional shape of the channel is consistent with the cross-sectional shape of the thermostat to ensure that the thermostat passes through and is connected to the heat dissipation component. In this embodiment, the shell 11 can be made of a heat-insulating material.

[0078] In this embodiment, air holes for the cooling fan are provided on the heat dissipation hole plate 13 at positions corresponding to the cooling fan 432 in the heat dissipation assembly 43, so as to realize the air flow of the cooling fan and ensure the heat dissipation efficiency of the fin heat sink.

[0079] In this embodiment, the other side of the housing 11 (i.e., one side in the width direction) is provided with a control unit compartment 11c for installing the control unit 5 and a locking mechanism compartment 11d for installing a locking structure for locking the box cover 2. In this embodiment, the control unit compartment 11c is located below the locking mechanism compartment 11d.

[0080] Combination Fig.11 and Fig.12 As shown, in this embodiment, the outer shape of the insulation layer 12 matches the shape of the internal cavity of the outer shell 11, so that the gap between the insulation layer and the outer shell can be effectively eliminated, which is beneficial to ensuring the sealing performance of the entire transfer box.

[0081] In this embodiment, the thermal insulation layer 12 is provided with a receiving cavity 121 matching the inner liner 41, and the opening of the receiving cavity 121 is located at the upper end surface of the thermal insulation layer 12; an interlocking cavity 122 interlocking with the power supply compartment 11b is provided on one side of the length direction of the thermal insulation layer 12, and a thermostat installation channel for embedding the thermostat 42 is provided on the other side of the length direction of the thermal insulation layer 12, and the thermostat installation channel passes through the side of the thermal insulation layer 12 and the receiving cavity 121 to achieve the installation of the thermostat. In this embodiment, the internal shape of the thermostat installation channel matches the shape of the thermostat 42, and the installed thermostat 42 can be sealed circumferentially to eliminate the transfer of its excess heat, thereby ensuring the thermostat control effect of the present invention.

[0082] Through the above configuration, by providing the interlocking cavity 122 on the thermal insulation layer 12, the lithium battery power source 3 in the power source compartment 11b can be effectively insulated, and the influence of the heat generated by the lithium battery power source 3 on the present invention can be effectively avoided. In addition, by providing the structure of the interlocking cavity on the thermal insulation layer so as to surround the power source compartment on the shell, the soft surrounding of the power source compartment 11b can also be effectively achieved, thereby playing the role of vibration reduction installation of the power source, which is beneficial to ensuring the safety of the present invention during transportation.

[0083] According to an embodiment of the present invention, the bottom of the inner liner 41 is provided with a plurality of connecting legs, and the bottom of the accommodating cavity 121 of the thermal insulation layer 12 is provided with a plurality of leg mounting holes that match the connecting legs, and the inner liner 41 is inserted into the leg mounting holes of the accommodating cavity 121 through the connecting legs at the bottom to achieve accurate positioning of the inner liner. In this embodiment, threaded holes may also be provided on the connecting legs, and the inner liner 41 and the thermal insulation layer 12 are further fixed by connecting the threaded connector to the connecting legs.

[0084] like Figure 7 As shown, according to one embodiment of the present invention, along the height direction of the housing 11, a ventilation hole is provided at the bottom of the heat dissipation component compartment 11a of the housing 11, and the top inner side surface of the heat dissipation component compartment 11a of the housing 11 is an inclined surface. In this embodiment, along the direction away from the inner tank 41, the top inner side surface extends obliquely in the direction away from the bottom.

[0085] In this embodiment, the length direction of the fins in the fin heat sink 431 is parallel to the height direction of the shell 11, that is, the fins are arranged at intervals along a direction perpendicular to the height direction, and the intervals between adjacent fins are relative to the ventilation holes at the bottom of the heat dissipation component bin 11a, thereby ensuring the consistency of the gas flow direction.

[0086] By setting the top inner side surface of the heat dissipation component bin 11a as an inclined surface, an inclined cavity can be formed between the upper part of the heat dissipation component bin 11a and the heat dissipation component 43, so that the cavity is also opposite to the interval between the fins, which is beneficial to the air guidance and realizes the rapid passage of airflow, further ensuring the stable heat exchange efficiency with the fins on the fin heat sink.

[0087] like Fig. 9 As shown, in this embodiment, ventilation holes are provided at positions corresponding to the top inner side surfaces of the heat dissipation hole plate 13 and the heat dissipation component compartment 11a, thereby achieving stable and rapid input and output of airflow.

[0088] like Figure 7 As shown, according to one embodiment of the present invention, at least one annular protrusion 111a is coaxially arranged on the upper end surface of the housing 11 and the opening 111. In this embodiment, two annular protrusions 111a are arranged on the upper end surface of the housing 11, and the plurality of annular protrusions 111a are arranged at intervals. In this embodiment, the heights of the plurality of annular protrusions 111a protruding from the upper end surface are consistent. In this embodiment, the annular protrusion 111a has a certain width.

[0089] Combination Figure 6 and Fig.13 As shown, in this embodiment, the upper end of the inner liner 41 protrudes from the upper end surface of the thermal insulation layer 12 , and the upper end surface of the inner liner 41 is flush with the upper end surface of the outer shell 11 .

[0090] According to another embodiment of the present invention, a continuous annular heat-insulating strip may be provided at the upper end of the inner liner 41, and the heat-insulating strip is fixedly connected to the inner liner 41 or sleeved on the inner liner 41. When the inner liner is installed in the box body 1, the heat-insulating strip is flush with the upper end surface of the outer shell 11. By providing the heat-insulating strip on the inner liner, the heat exchange at the end of the inner liner is further reduced, which is further beneficial to ensuring the constant temperature effect of the present invention.

[0091] Combination Figure 2 , Figure 5 , Figure 6 and Fig.13As shown, according to an embodiment of the present invention, the control unit 5 includes: a control component 51, a display 52, a sensor, a hollow first connecting pipe 53, a second connecting pipe 54 and a third connecting pipe 55.

Among them, the opposite ends of the first connecting pipe 53 are respectively connected to the heat dissipation component compartment 11a and the control unit compartment 11c on the shell 11; the opposite ends of the second connecting pipe 54 are respectively connected to the accommodating cavity 121 in the thermal insulation layer 12 and the control unit compartment 11c on the shell 11; the opposite ends of the third connecting pipe 55 are respectively connected to the power supply compartment 11b and the control unit compartment 11c on the shell 11. In this embodiment, the sensor is arranged in the second connecting pipe 54 and contacts the inner liner 41 embedded in the thermal insulation layer 12.

[0092] In this embodiment, by disposing the sensor in the second connecting tube 54 , the second connecting tube 54 and the sensor can be sealed to isolate the connection between the inner liner 41 and other chambers, thereby being beneficial to ensuring the constant temperature effect of the inner liner 41 .

[0093] Through the above arrangement, not only the electrical connection between the units is achieved through the first connecting tube 53, the second connecting tube 54 and the third connecting tube 55, but also the ventilation and cooling of each part by the heat dissipation component can be achieved through the pipe connection, which is beneficial to suppressing the heat accumulation in each cavity, and further ensures the precise constant temperature control of the present invention.

In this embodiment, one side of the cover body 21 is rotatably connected to the outer shell 11 of the box body 1, and the other side is provided with a locking assembly 22 for opening and closing with the outer shell 11. In this embodiment, a side of the cover body 21 that is engaged with the box body 1 is provided with a snap-fitting boss 23 that can be snapped with the opening of the inner liner 41. In this embodiment, the cross-sectional shape of the snap-fitting boss 23 is matched with the opening shape of the inner liner 41.

[0095] Through the above arrangement, when the box cover 2 and the box body 1 are buckled together, the buckling boss 23 can be engaged with the opening end of the inner liner 41 to achieve the closure of the inner liner opening, which is beneficial to ensuring the sealing of the internal space of the inner liner, and thus is beneficial to ensuring the constant temperature effect of the present invention.

[0096] Combination Fig.14 , Fig.15 and Fig.16As shown, according to one embodiment of the present invention, at least one annular groove 24 is provided on one side of the cover body 21 that is buckled with the box body 1, and an annular sealing strip 25 is embedded in the annular groove 24.

[0097] According to an embodiment of the present invention, the annular sealing strip 25 is a solid sealing strip with a rectangular cross section, which is detachably embedded in the annular groove 24.
