Description

Technical Field

[0001] This utility model relates to the technical field of drug stability testing chamber equipment, and in particular to a moisture-proof drug stability testing chamber. Background Technology

[0002] A pharmaceutical light stability test chamber is a device used to simulate the stability testing of pharmaceuticals under strong light. It uses scientific methods to create a stable temperature, humidity, and light environment for a long time required for evaluating drug failure. It is commonly used by pharmaceutical companies for scientific research such as accelerated testing, high humidity testing, and strong light irradiation testing of new drugs. However, existing pharmaceutical stability test chambers generally use compressor refrigeration to control the humidity inside the chamber, and the refrigerant used in the compressor may affect the experimental testing of pharmaceuticals.

[0003] For example, Chinese utility model patent CN201841017U discloses a drug stability testing chamber, including a chamber body and a door. The refrigeration system includes a condenser and a compressor unit connected to it. Although this solution has many advantages such as simple structure and convenient assembly and maintenance, the fluorinated refrigerant on which the compressor refrigeration depends, such as the new environmentally friendly refrigerant R410A (hydrofluorocarbon), has a freezing point of -155℃ and a boiling point of -51.6℃. It is colorless but highly volatile. Once a leak occurs, it may mix into the drug stability testing chamber and directly affect the drug test results. Based on this, a moisture-proof drug stability testing chamber that can solve the above problems is proposed. Utility Model Content

[0004] To address the technical problem of noise in pharmaceutical stability testing chambers, this invention provides a moisture-proof pharmaceutical stability testing chamber.

[0005] This utility model is achieved using the following technical solution: a moisture-proof drug stability testing box, comprising a shell, a clamping plate fixedly connected to one side of the shell, multiple grooves formed on one side of the clamping plate, the multiple grooves being arranged in a circumferential array, multiple condensing plates fixedly connected to the side of the clamping plate away from the grooves, a semiconductor cooling chip disposed in each groove, the multiple semiconductor cooling chips being electrically connected to a control panel on the outside of the shell, a circulating dehumidification mechanism disposed on one side of the condensing plate, a cooling chip heat dissipation mechanism disposed on one side of the multiple semiconductor cooling chips, and a condensate recovery mechanism disposed below the condensing plate.

[0006] As a further improvement to the above solution, the circulating dehumidification mechanism includes a cabinet fixedly connected to the inside of the housing, a centrifugal fan connected to the side of the cabinet near the semiconductor cooling chip, and an air duct mechanism provided on the lower side of the centrifugal fan.

[0007] As a further improvement to the above solution, the air duct mechanism includes an air duct that communicates with the lower side of the centrifugal fan, the air duct being fixedly connected to one side of the clamping plate, and a plurality of the condensing plates being located inside the air duct.

[0008] As a further improvement to the above solution, the heat dissipation mechanism includes a mounting plate that is fixedly connected to one side of the plurality of semiconductor cooling chips, and a plurality of heat dissipation fins are mounted on one side of the mounting plate.

[0009] As a further improvement to the above solution, the condensate recovery mechanism includes a limiting cylinder that communicates with the lower end of the air duct, a water collection hopper that is slidably connected to the inner side of the limiting cylinder, and an overflow valve installed on the side of the water collection hopper away from the limiting cylinder.

[0010] As a further improvement to the above solution, some of the air ducts away from the semiconductor cooling chip are connected to a drying filter unit, and the side of the drying filter unit away from the air duct is connected to the cabinet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses multiple semiconductor cooling chips to cool the condenser plate. When the air inside the cabinet is loaded and passes through the air duct, it condenses upon contact with the condenser plate, forming condensate water, thereby achieving the purpose of dehumidification and moisture prevention. The semiconductor cooling chip cooling method is green and environmentally friendly, does not produce toxic or harmful substances, and will not affect the drug testing carried out inside the cabinet.

[0013] 2. This utility model uses multiple semiconductor cooling chips installed in the groove between the clamping plate and the mounting plate for cooling. When one of the semiconductor cooling chips fails, the mounting plate can be opened from the outside for replacement. Compared with the operation of traditional compressors that require adding refrigerant when the refrigerant is insufficient, this utility model has the advantages of simple maintenance and convenient use.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figures 1-5 This embodiment of a moisture-proof drug stability testing box includes a shell 1. A clamping plate 11 is fixedly connected to one side of the interior of the shell 1. The clamping plate 11 is made of metal and has excellent thermal conductivity. Multiple grooves 13 are provided on one side of the clamping plate 11, and the multiple grooves 13 are arranged in a circumferential array. Multiple condensing plates 12 are fixedly connected to the side of the clamping plate 11 away from the grooves 13. When humid air encounters the low-temperature condensing plates 12, condensate can be generated. A semiconductor cooling chip 10 is provided in each groove 13. The multiple semiconductor cooling chips 10 are electrically connected to the control panel on the outside of the shell 1. A circulating dehumidification mechanism is provided on one side of the condensing plate 12. A cooling chip heat dissipation mechanism is provided on one side of the multiple semiconductor cooling chips 10. A condensate recovery mechanism is provided below the condensing plate 12.

[0024] Through the above technical solution, the semiconductor cooling chip 10 can be used to cool the condenser plate 12, and the low-temperature condenser plate 12 can be used to cool and condense the humid air, thereby achieving the purpose of dehumidification. In addition, this cooling method has the advantages of being quiet and environmentally friendly, without producing harmful substances that enter the cabinet 3, thus achieving the effect of not affecting the drug testing.

[0025] Please combine Figure 1 and Figure 3 As shown, the circulating dehumidification mechanism includes a cabinet 3 fixedly connected to the inside of the housing 1. The cabinet 3 has multiple placement plates inside, which can be used to place various kinds of medicines that need to be tested. A centrifugal fan 2 is connected to the side of the cabinet 3 near the semiconductor cooling chip 10, and an air duct mechanism is provided on the lower side of the centrifugal fan 2.

[0026] Through the above technical solution, the centrifugal fan 2 draws air from inside the cabinet 3 and outputs air from the bottom.

[0027] Please combine Figure 3 As shown, the air duct mechanism includes an air duct 8 that is connected to the lower side of the centrifugal fan 2. One side of the air duct 8 is hollowed out. The air duct 8 is fixedly connected to one side of the clamping plate 11. Multiple condensing plates 12 are located inside the air duct 8.

[0028] Please combine Figure 5 As shown, the heat dissipation mechanism includes a mounting plate 4 that is fixedly connected to one side of multiple semiconductor cooling chips 10. Multiple heat dissipation fins 6 are installed on one side of the mounting plate 4. The mounting plate 4 and the clamping plate 11 are detachably connected. It should be noted that in this embodiment, heat dissipation is achieved by directly installing heat dissipation fins 6 on one side of the mounting plate 4, that is, by increasing the heat dissipation area. In other embodiments, air cooling can be achieved by adding a DC fan above the multiple heat dissipation fins 6 to accelerate the airflow rate around the heat dissipation fins 6.

[0029] Please combine Figure 4 As shown, the condensate recovery mechanism includes a limiting cylinder 9 connected to the lower end of the air duct 8. The limiting cylinder 9 has a square tube frame structure. A water collection hopper 5 is slidably connected to the inner side of the limiting cylinder 9. An overflow valve is installed on the side of the water collection hopper 5 away from the limiting cylinder 9.

[0030] When the condensate in the water collection hopper 5 is full, it can be cleaned by pulling the water collection hopper 5 out of the limiting cylinder 9.

[0031] Please combine Figure 3 As shown, some of the air ducts 8 away from the semiconductor cooling chip 10 are connected to a dryer filter unit 7. The dryer filter unit 7 is equipped with a removable filter canister, which can be used to periodically replace the filter in the dryer filter unit 7. The side of the dryer filter unit 7 away from the air duct 8 is connected to the cabinet 3.

[0032] The implementation principle of a moisture-proof drug stability testing box in this application embodiment is as follows: the drug to be tested can be placed inside the cabinet 3, and then the centrifugal fan 2 is started, which pushes the air inside the cabinet 3 through the air duct 8 to the surface of the condenser plate 12. When the semiconductor cooling chip 10 is working, it can quickly cool the condenser plate 12. At this time, the humid air inside the cabinet 3 can condense into water, thereby achieving the purpose of dehumidification and moisture prevention. The condensate water is collected in the water collection hopper 5 along the condenser plate and the lower end of the air duct 8 under its own gravity. The dehumidified air passes through the drying filter unit 7 and is reinjected into the cabinet 3, which can keep the air pressure inside the cabinet 3 constant. When the semiconductor cooling chip 10 is working, its back heating surface can dissipate heat through the heat dissipation fins 6 installed on the outside of the mounting plate 4.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
