The adoption of the mode of embedding the refrigerant copper pipe in advance can lead the length of the refrigerant embedded in advance to be fixed, the adjustment can not be carried out according to the position change of the evaporator, the welding difficulty between the evaporator and the refrigerant copper pipe is higher, and the production and assembly efficiency of the refrigerating box is low.

Referring to fig. 1-7, embodiments of the present disclosure provide a medical cooler, comprising: the refrigerator body 100, the built-in box 200, the evaporator 300 and the refrigerant pipe group 400.

In the embodiment of the present disclosure, the refrigerant pipe set 400 is partially embedded in the foaming layer 120 between the tank 100 and the inner container 110, the refrigerant pipe set 400 is wrapped in a thermal insulation manner, the embedded box 200 is embedded in the inner wall of the inner container 110, the part of the embedded box 200 is embedded in the foaming layer 120, the port 410 of the refrigerant pipe set 400 passes through the embedded box 200 and extends into the embedded box 200 to be hidden, the port 410 of the refrigerant pipe set 400 can be moved out of the embedded box 200, after the foaming between the tank 100 and the inner container 110 is completed, the port 410 of the refrigerant pipe set 400 in the embedded box 200 can be moved to the position of the pipe orifice 310 of the evaporator 300, and the port 410 of the refrigerant pipe set 400 is welded to the pipe orifice 310 of the evaporator 300.

According to the medical refrigerator provided by the embodiment of the disclosure, the embedded box 200 is embedded in the foaming layer 120 between the box body 100 and the liner 110, so that the port part 410 of the refrigerant pipe group 400 is movably hidden in the embedded box 200, and the influence on the port part 410 of the refrigerant pipe group 400 during foaming of the foaming layer 120 is reduced. The relatively long refrigerant pipe set 400 can be placed in the embedded box 200, so that the port part 410 of the refrigerant pipe set 400 can move from the embedded box 200 to the pipe orifice 310 of the evaporator 300 and can be adjusted according to the position of the pipe orifice 310 of the evaporator 300, the port part 410 of the refrigerant pipe set 400 is conveniently welded and communicated with the pipe orifice 310 of the evaporator 300, the welding difficulty between the evaporator 300 and the refrigerant pipe set 400 is reduced, and the production and assembly efficiency of the medical refrigerating box is improved.

Optionally, the box 100 is a vertically arranged rectangular structure, and the inner container 110 is a rectangular cavity structure arranged inside the box 100. Like this, the box 100 of cuboid structure is convenient for place, and stability is higher, and the inner bag 110 of cuboid structure can be convenient for deposit the biological sample with the shape adaptation of box 100, improves the space utilization of inner bag 110.

Optionally, a heat dissipation chamber 500 is further disposed inside the tank 100, a compressor 510 and a condenser 520 are disposed in the heat dissipation chamber 500, and the compressor 510 and the condenser 520 are respectively communicated with the refrigerant tube set 400. In this way, the compressor 510 and the condenser 520 are disposed in the heat dissipation chamber 500, so that heat generated when the compressor 510 and the condenser 520 operate can be dissipated to the external environment through the heat dissipation chamber 500, the evaporator 300, the compressor 510, and the condenser 520 are communicated through the refrigerant pipe group 400, and refrigerant circulates among the evaporator 300, the compressor 510, and the condenser 520 to cool the medical refrigerator.

It can be understood that the compressor 510, the evaporator 300 and the condenser 520 are respectively communicated with the refrigerant tube set 400 to form a refrigeration system of the medical refrigerating box, and the refrigeration system should have components necessary for the refrigeration system, such as an electronic expansion valve, a capillary tube, etc., which are not described herein again.

Optionally, the refrigerant pipe set 400 is disposed along the vertical direction, the port portion 410 of the refrigerant pipe set 400 located in the embedded box 200 is an upper port portion, and a lower port portion of the refrigerant pipe set 400 extends into the heat dissipation cavity 500 and is respectively communicated with the compressor 510 and the condenser 520. Like this, because this medical fridge's box 100 is the rectangular body structure of vertical placement, inner bag 110 is the rectangle cavity structure rather than shape adaptation, consequently the length of the foaming layer 120 between box 100 and inner bag 110 is great in vertical direction, set up refrigerant nest of tubes 400 along vertical direction, make most of refrigerant nest of tubes 400 all can bury underground and keep warm isolated in foaming layer 120, reduce the temperature loss of refrigerant when flowing through refrigerant nest of tubes 400, reduce the production of condensation.

Referring to fig. 2, in some embodiments, the heat dissipation chamber 500 has a heat dissipation port 531 and an air return port 541, which are communicated with the outside, a first installation chamber 530 and a second installation chamber 540 are disposed in the heat dissipation chamber 500, the condenser 520 is installed in the first installation chamber 530, the compressor 510 is installed in the second installation chamber 540, the first installation chamber 530 is communicated with the second installation chamber 540, the heat dissipation port 531 is located on a side wall of the first installation chamber 530, the air return port 541 is located on a side wall of the second installation chamber 540, the first installation chamber 530 is further provided with a heat dissipation fan 532, an air outlet end of the heat dissipation fan 532 faces the heat dissipation port 531, the condenser 520 is located between an air outlet end of the heat dissipation fan 532 and the heat dissipation port 531, and the compressor 510 is located between an air inlet end of the heat dissipation fan 532 and the air return port 541. Thus, under the action of the heat dissipation fan 532, the airflow in the external environment flows into the second mounting cavity 540 through the air return opening 541, then flows into the first mounting cavity 530 and blows towards the condenser 520, and the airflow blowing towards the condenser 520 exchanges heat and then blows out from the heat dissipation opening 531. Disposing condenser 520 within first mounting cavity 530 and compressor 510 within second mounting cavity 540 reduces interference between condenser 520 and compressor 510. Because the temperature of the condenser 520 is higher than that of the compressor 510, the air flow flowing into the air return opening 541 firstly flows through the second mounting cavity 540 to dissipate the heat of the compressor 510, and then flows into the first mounting cavity 530 to dissipate the heat of the condenser 520, the compressor 510 and the condenser 520 can be simultaneously dissipated by utilizing the introduced external air flow, the influence of the heat of the condenser 520 on the compressor 510 is avoided, and the refrigeration stability of the medical refrigerating box is improved.

Specifically, a partition plate 550 is arranged between the compressor 510 and the condenser 520, the partition plate 550 divides the heat dissipation chamber 500 into a first mounting chamber 530 and a second mounting chamber 540, an overflowing gap 551 is arranged between the end of the partition plate 550 and the inner wall of the heat dissipation chamber 500, and the first mounting chamber 530 is communicated with the second mounting chamber 540 through the overflowing gap 551. In this way, the partition 550 is arranged to further reduce the influence of the heat of the condenser 520 on the compressor 510, the external air flow flows into the second mounting cavity 540 from the air return opening 541 under the action of the heat dissipation fan 532 to exchange heat with the compressor 510 to cool the compressor 510, and the air flow after heat exchange flows into the first mounting cavity 530 from the overflowing gap 551 to exchange heat with the condenser 520 and then is blown out from the heat dissipation opening 531.

Specifically, the flow gap 551 is located on the air inlet side of the heat dissipation fan 532. The negative pressure generated at the air inlet end of the cooling fan 532 can be better applied to the supercooling gap, so that the air flow in the first mounting cavity 530 is sucked, the loss of the air flow pressure is reduced, and the cooling effect is improved.

Referring to fig. 3, in some embodiments, the refrigerant tube assembly 400 includes: an inlet pipe 420 and an outlet pipe 430. The inlet pipe 420 is partially embedded in the foaming layer 120; the air return pipe 430 is partially embedded in the foaming layer 120; the port portion 410 of the refrigerant pipe group 400 includes a port of the inlet/outlet pipe 420 and a port of the return pipe 430, and both the port of the inlet/outlet pipe 420 and the port of the return pipe 430 are movably disposed in the embedded box 200. Thus, the refrigerant in the condenser 520 flows into the evaporator 300 through the inlet/outlet pipe 420, evaporates and absorbs heat in the evaporator 300 to cool the internal environment of the inner container 110, and the evaporated refrigerant flows into the return pipe 430, and then flows into the compressor 510 through the return pipe 430 to complete a primary refrigerant cycle. The inlet and outlet pipes 420 and the air return pipe 430 are partially embedded in the foaming layer 120, and because the inlet and outlet pipes 420 and the air return pipe 430 need to be welded and communicated with the evaporator 300 when the refrigerant pipe set 400 is welded and communicated with the evaporator 300, the ports of the inlet and outlet pipes 420 and the air return pipe 430 are movably arranged in the embedded box 200, and after the foaming of the foaming layer 120 is completed, the ports of the inlet and outlet pipes 420 and the air return pipe 430 can be moved to the pipe orifice 310 of the evaporator 300, so that the inlet and outlet pipes 420 and the air return pipe 430 can be conveniently welded and communicated with the evaporator 300, and the production and assembly efficiency of the medical refrigerating box is improved.

Optionally, the upper side ports of the inlet and outlet pipe 420 and the air return pipe 430 are movably disposed in the embedded box 200, and are respectively connected with the pipe orifice 310 of the evaporator 300; the lower side ports of the inlet pipe 420 and the outlet pipe 430 extend into the heat dissipation chamber 500 and are connected with the compressor 510 and the condenser 520, respectively.

Specifically, the outlet end of the compressor 510 is communicated with the inlet end of the condenser 520, the outlet end of the condenser 520 is communicated with the inlet end of the evaporator 300 through the inlet and outlet pipes 420, and the outlet end of the evaporator 300 is communicated with the inlet end of the compressor 510 through the return air pipe 430. During refrigeration, the gaseous refrigerant in the compressor 510 flows into the condenser 520 to release heat from the refrigerant and then turns into a liquid refrigerant, the liquid refrigerant flows into the evaporator 300 through the inlet/outlet pipe 420 to evaporate and absorb heat to turn into a gaseous refrigerant, and the gaseous refrigerant flows into the compressor 510 again through the return pipe 430 to be compressed.

Optionally, the nozzle 310 of the evaporator 300 comprises: an inlet-outlet nozzle 311 and an air return nozzle 312. The inlet-outlet pipe 311 is connected with the port of the inlet-outlet pipe 420; the return air pipe port 312 is connected to a port of the return air pipe 430. When the tube opening 310 of the evaporator 300 and the port portion 410 of the refrigerant tube group 400 are welded, the inlet/outlet tube opening 311 of the evaporator 300 is connected to the port of the inlet/outlet tube 420, the return air tube opening 312 of the evaporator 300 is connected to the port of the return air tube 430, the refrigerant flowing out of the condenser 520 flows into the evaporator 300 through the inlet/outlet tube opening 311 to be evaporated and absorb heat, and the evaporated gaseous refrigerant flows into the return air tube 430 from the return air tube opening 312, thereby ensuring the refrigeration stability of the medical refrigerator.

Illustratively, when the medical refrigerating box is produced and assembled, the inlet and outlet pipes 420 and the air return pipe 430 are partially embedded in the foaming layer 120, the upper side ports of the inlet and outlet pipes 420 and the air return pipe 430 extend into the embedded box 200 and are movably arranged, the lower side ports of the inlet and outlet pipes 420 and the air return pipe 430 extend into the heat dissipation cavity 500, the lower side ports of the inlet and outlet pipes 420 are connected with the outlet end of the condenser 520, and the lower side ports of the air return pipe 430 are connected with the inlet end of the compressor 510. After the foaming layer 120 is foamed, the worker pulls the inlet/outlet pipe 420 and the upper port of the air return pipe 430 in the embedded box 200 out of the embedded box 200, so that the upper port of the inlet/outlet pipe 420 is located at the inlet/outlet pipe opening 311, the upper port of the air return pipe 430 is located at the air return pipe opening 312, and then the upper port of the inlet/outlet pipe 420 is welded to the inlet/outlet pipe opening 311, and the upper port of the air return pipe 430 is welded to the air return pipe opening 312.

Specifically, the inlet and outlet pipe 420 and the air return pipe 430 are made of copper pipes. The copper pipe has better corrosion resistance and heat conduction performance, and has certain flexibility, so that the ports of the inlet and outlet pipes 420 and the air return pipe 430 are pulled out to be respectively welded with the inlet and outlet pipe orifice 311 and the air return pipe orifice 312 of the evaporator 300, and the production and assembly efficiency of the medical refrigerating box is improved.

In some embodiments, as shown in fig. 4, the inner container 110 has an opening 111, and the nozzle 310 of the evaporator 300 is located on a side of the evaporator 300 facing the opening 111. Thus, when the medical refrigerator is produced and assembled, a worker needs to perform a welding operation through the opening 111 of the inner container 110, so that the port 310 of the evaporator 300 is disposed at a side of the evaporator 300 facing the opening 111, when the port 410 of the refrigerant tube set 400 is pulled out to a position of the port 310 of the evaporator 300, the port 410 of the refrigerant tube set 400 and the port 310 of the evaporator 300 are exposed to the worker, thereby facilitating the welding operation of the worker, and further improving the production and assembly efficiency of the medical refrigerator. The opening 111 can also be used as a taking and placing opening of the liner 110, and when the medical refrigerating box is put into use, a biological sample can be taken and placed through the opening 111.

Optionally, the embedded box 200 is embedded in the upper inner wall of the inner container 110, and the evaporator 300 is fixedly disposed on the upper inner wall of the inner container 110 and located below the embedded box 200. In this way, the evaporator 300 is fixedly installed on the upper inner wall of the inner container 110, so that the cold air flow after heat exchange can gradually diffuse from the upper region of the inner container 110 to the lower region of the inner container 110, thereby forming a shower-type cold air flow, and improving the cooling effect inside the inner container 110 by utilizing the natural sinking characteristic of the cold air flow. Since the position of the pipe port 310 of the evaporator 300 corresponds to the cartridge 200, the cartridge 200 is fitted into the upper inner wall of the inner container 110, so that the port 410 of the refrigerant pipe group 400 in the cartridge 200 can be smoothly welded to the pipe port 310 of the evaporator 300 when being pulled out. And the embedded box 200 is arranged above the evaporator 300, so that the embedded box 200 and the evaporator 300 can generate condensed water which can be conveniently contained.

Optionally, the lower sidewall of the embedded box 200 and the upper inner wall of the inner container 110 are in the same plane, the lower sidewall of the embedded box 200 has an opening 210, and the port portion 410 of the refrigerant pipe set 400 can extend out to the position of the pipe orifice 310 of the evaporator 300 through the opening 210. Like this, the lower lateral wall with pre-buried box 200 and the upside inner wall setting of inner bag 110 are in the coplanar, and the lower lateral wall of pre-buried box 200 is parallel and level with the upside inner wall of inner bag 110 promptly, can avoid pre-buried box 200 to stretch into the inside too much occupation space of inner bag 110. The opening 210 is formed in the lower sidewall of the cartridge 200, and the port 410 of the refrigerant tube set 400 can be drawn out to the nozzle 310 of the evaporator 300 through the opening 210, so that the port 410 of the refrigerant tube set 400 can be welded to the nozzle 310 of the evaporator 300.

Specifically, in the vertical downward direction, the evaporator 300 covers part of the opening 210 of the embedded box 200. In this way, since the evaporator 300 is disposed below the embedment box 200, the embedment box 200 and the evaporator 300 can easily receive condensed water, but in order to easily draw out the port portion 410 of the refrigerant tube group 400 in the embedment box 200 and weld the port portion with the pipe orifice 310 of the evaporator 300, the evaporator 300 is disposed in an offset manner to reserve a draw-out space for the opening 210 of the embedment box 200, so that the port portion 410 of the refrigerant tube group 400 can be smoothly drawn out.

Referring to fig. 5, 6 and 7, in some embodiments, the medical cooler further comprises: an air duct cover 600. The air duct cover 600 covers the inner wall of the upper side of the inner container 110, the air duct cover 600 and the inner wall of the upper side of the inner container 110 jointly define a heat exchange air duct 610, the evaporator 300 is fixedly arranged in the heat exchange air duct 610, and the inner wall of the upper side of the inner container 110 where the embedded box 200 is located in the covering range of the air duct cover 600. In this way, the evaporator 300 is fixedly installed on the inner wall of the upper side of the inner container 110 by the air duct cover 600, and the heat exchange air duct 610 is defined by the inner wall of the air duct cover 600 and the inner wall of the upper side of the inner container 110, so that the production cost of the air duct cover 600 can be reduced. Cover the pre-buried box 200 of evaporimeter 300 and evaporimeter 300 top through wind channel cover 600 and establish jointly, the comdenstion water that pre-buried box 200 inner wall and the port portion 410 of refrigerant nest of tubes 400 produced can drip at the lower side inner wall of evaporimeter 300 or wind channel cover 600 under the effect of gravity, utilizes wind channel cover 600 to act as the comdenstion water that the water collector produced in coming to hold evaporator 300 and pre-buried box 200 simultaneously, need not additionally to set up the water collector structure.

Optionally, a transverse support 620 is disposed in the air duct casing 600, two ends of the transverse support 620 are respectively fixed to two opposite side walls of the air duct casing 600, and the evaporator 300 is fixedly disposed on the upper side of the transverse support 620. Like this, utilize horizontal stand 620 to form the support to evaporimeter 300, avoid the lower extreme contact wind channel cover 600 of evaporimeter 300's downside inner wall, when wind channel cover 600 connects the comdenstion water greatly, avoid the lower extreme of evaporimeter 300 to soak and influence the heat transfer effect in the comdenstion water.

Optionally, there is a gap between the upper sidewall of the cross bracket 620 and the lower inner wall of the duct cover 600 in the vertical direction. Therefore, the transverse support 620 is prevented from blocking the inner wall of the lower side of the air duct housing 600, so that the condensed water contained in the air duct housing 600 can smoothly circulate, and the condensed water is convenient to discharge.

Optionally, as shown in fig. 6, the lower side surface of the duct casing 600 is divided into a first inclined section 630 and a second inclined section 640, opposite ends of the first inclined section 630 and the second inclined section 640 are connected, the first inclined section 630 and the second inclined section 640 are both inclined towards the inner wall of the upper side of the inner container 110, the inclined angle of the first inclined section 630 is smaller than that of the second inclined section 640, and the lower side wall of the first inclined section 630 is provided with a through drain pipe 631. Therefore, the condensed water dropping from the embedded box 200 and the evaporator 300 can be contained and connected by the first inclined section 630 and the second inclined section 640, and the inclined angle of the first inclined section 630 is smaller than that of the second inclined section 640, so that the contained condensed water can flow to the inner wall of the first inclined section 630 along the inner wall of the second inclined section 640, the lower side wall of the first inclined section 630 is provided with the through drain pipe 631, the contained condensed water can be discharged to the outside along the drain pipe 631, and the condensed water is prevented from accumulating in the air duct housing 600.

Specifically, the position where the drain pipe 631 communicates with the first inclined section 630 is located at the lowermost end of the first inclined section 630. So that the condensed water can be discharged along the drain pipe 631 better by the gravity.

Specifically, the upper end of the drain pipe 631 penetrates the first inclined section 630, and the lower end of the drain pipe 631 communicates with the external environment of the inner container 110. The condensed water contained in the duct cover 600 can be discharged to the outside of the inner container 110 through the drain pipe 631.

It can be understood that a water storage structure such as a water storage box may be disposed on the outer sidewall of the box 100, and the lower end of the drain pipe 631 penetrates through the box 100 and is communicated with the water storage structure such as the water storage box.

Optionally, as shown in fig. 7, the air duct cover 600 has an air inlet 611 and an air outlet 612, the air inlet 611 is disposed at one end of the heat exchange air duct 610, the air outlet 612 is disposed at the other end of the heat exchange air duct 610, and the air outlet 612 is located on the second inclined section 640. Thus, the air flow in the inner container 110 flows into the air duct cover 600 through the air inlet 611, and is blown out from the air outlet 612 after exchanging heat with the evaporator 300 in the air duct cover 600, and the cold air flow after heat exchange is diffused in the inner container 110 from top to bottom, so that the refrigeration effect of the inner container 110 is improved. The air outlet 612 is arranged at the second inclined section 640, and because the inclination angle of the second inclined section 640 is relatively large, the condensed water contained in the air duct housing 600 can be prevented from being blown out of the air outlet 612 along with the air flow. The cool air flow blown out from the outlet 612 flows obliquely downward of the inner container 110, and the temperature uniformity in the inner container 110 is further improved.

Specifically, the air inlet 611 is disposed on a side wall of the air duct cover 600 corresponding to the windward side of the evaporator 300, and a preset distance is provided between a lower side edge of the air inlet 611 and a lower side surface of the air duct cover 600 along the vertical direction. Therefore, the air flow flowing in from the air inlet 611 can exchange heat with the evaporator 300, and the condensed water contained in the air duct cover 600 is prevented from flowing out from the air inlet 611.

Specifically, a fan is disposed at the air outlet 612. The rotation of the fan provides the power for air outlet, so that negative pressure is formed in the heat exchange air duct 610, and air flow is sucked from the air inlet 611 for heat exchange.

Optionally, the angle of inclination between the first inclined section 630 and the horizontal is greater than 0 ° and less than or equal to 10 °; the angle of inclination between the second inclined section 640 and the horizontal is greater than 10 ° and less than or equal to 30 °. In this way, when the inclination angle between the second inclined section 640 and the horizontal plane is less than or equal to 10 °, the inclination angle of the second inclined section 640 is small, and the condensed water is easily blown out from the air outlet 612 by the wind. In the case that the inclination angle between the second inclined section 640 and the horizontal plane is greater than 30 °, the inclination angle of the second inclined section 640 is too large, and the airflow blown out from the air outlet 612 flows too much toward the vertical sidewall of the inner container 110, so that the temperature uniformity inside the inner container 110 is reduced. Therefore, the inclination angle between the second inclined section 640 and the horizontal plane is set to be greater than or equal to 10 ° and less than or equal to 30 °, so that the risk of blowing out the condensed water through the air outlet 612 can be reduced, and the temperature uniformity in the inner container 110 can be improved. Moreover, the inclination angle between the first inclined section 630 and the horizontal plane is set to be larger than 0 degree and smaller than or equal to 10 degrees, so that the first inclined section 630 not only has the water guiding effect, but also can better contain and receive the condensed water.

Specifically, the angle of inclination between the first inclined section 630 and the horizontal plane is equal to 8 °, and the angle of inclination between the second inclined section 640 and the horizontal plane is equal to 15 °.

Optionally, the evaporator 300 is disposed above the first inclined section 630. In this way, since the amount of condensed water generated by the evaporator 300 is relatively large, the evaporator 300 is directly disposed above the first inclined section 630, so that the condensed water dropped from the evaporator 300 can directly drop on the first inclined section 630 to be received, thereby improving the water receiving effect.

Specifically, in the vertical direction, there is no overlapping area between the projection of the embedded box 200 on the lower side surface of the air duct casing 600 and the air outlet 612. Therefore, condensed water generated in the embedded box 200 is prevented from dropping on the air outlet 612, and the risk of blowing water at the air outlet 612 is further reduced.
