Semiconductor refrigeration chips are usually used to cool the reagents. The semiconductor refrigeration chip has a heating end and a cooling end. When powered on, the cooling end will cool and the heating end will heat.

[0004] However, the above scheme mainly utilizes the air inside the shell to dissipate heat from the semiconductor refrigeration chip. When the temperature inside the shell is often higher than the ambient temperature, this will greatly reduce the heat dissipation effect of the semiconductor refrigeration chip, resulting in the refrigeration effect of the semiconductor refrigeration chip cannot be fully exerted.

[0040] In the related technology, the heat dissipation device includes a shell, in which a semiconductor refrigeration plate and a fan are arranged. The fan is arranged at the heating end of the semiconductor refrigeration plate. The heat at the heating end of the semiconductor refrigeration plate is transferred to the heat dissipation fins. The heat on the heat dissipation fins is blown out by the action of the fan to achieve heat dissipation of the semiconductor refrigeration plate.

[0041] However, the above scheme mainly utilizes the air inside the shell to dissipate heat from the semiconductor refrigeration chip. When the temperature inside the shell is often higher than the ambient temperature, this will greatly reduce the heat dissipation effect of the semiconductor refrigeration chip, resulting in the refrigeration effect of the semiconductor refrigeration chip cannot be fully exerted.

[0042] In view of the above problems, an embodiment of the present application provides a heat dissipation device that can utilize the ambient temperature to ventilate and dissipate heat for a semiconductor refrigeration unit, thereby greatly improving the refrigeration effect of the semiconductor refrigeration unit.

[0043] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0045] See also Figures 1 to 3 The embodiment of the present application provides a heat dissipation device, which is arranged on one side of a reagent storage device 5 and is used to adjust the temperature of the stored reagent; and the heat dissipation device includes a shell 1, an air inlet mechanism 3 and an air supply mechanism 4, the shell 1 has an air inlet 10 and an air outlet 11, the air inlet 10 and the air outlet 11 are arranged at intervals along the extension direction of the shell 1 and form a heat dissipation duct 12; and the shell 1 has a accommodating cavity 13 for accommodating a semiconductor refrigeration unit 2, and the accommodating cavity 13 is at least partially located in the heat dissipation duct 12; the air inlet mechanism 3 is arranged at the air inlet 10, and is used to suck ambient air into the heat dissipation duct 12 through the air inlet 10, so that the ambient air dissipates the heat of the hot end of the semiconductor refrigeration unit 2 through the accommodating cavity 13; the air supply mechanism 4 is arranged at the air outlet 11, and is used to discharge the heat of the hot end of the semiconductor refrigeration unit 2 through the air outlet 11.

[0046] The heat dissipation device in the embodiment of the present application can be arranged at the bottom of the reagent storage device 5 to adjust the temperature of the stored reagents without affecting the taking and placing of the stored reagents.

[0047] The housing 1 in the embodiment of the present application may include a base and a shell cover, the shell cover is arranged on the base, and an inner cavity is formed between the shell cover and the base, the base is provided with an air inlet 10 and an air outlet 11, the air inlet 10 and the air outlet 11 are arranged at intervals along the extension direction of the base, and are connected to the inner cavity. The inner cavity between the air inlet 10 and the air outlet 11 forms a heat dissipation duct 12.

[0048] The accommodating chamber 13 in the shell 1 of the embodiment of the present application is at least partially located in the heat dissipation duct 12. The accommodating chamber 13 may be located between the air inlet 10 and the air outlet 11, or may be located upstream of the air inlet 10 or downstream of the air outlet 11. The present application does not limit the position of the accommodating chamber 13, but the space of the accommodating chamber 13 at least partially overlaps with the space of the heat dissipation duct 12, so that the airflow in the heat dissipation duct 12 can pass through the semiconductor refrigeration unit 2 in the accommodating chamber 13 to dissipate heat to the semiconductor refrigeration unit 2.

[0049] The embodiment of the present application forms a heat dissipation duct 12 with a certain extension length inside the shell 1 between the air inlet 10 and the air outlet 11 by setting an air inlet 10 and an air outlet 11 spaced apart along the extension direction on the shell 1, so that the wind direction in the heat dissipation duct 12 is unidirectional, the air flow is continuous and unimpeded, and is not affected by air flow in other directions, which can greatly improve the heat dissipation effect; an air inlet mechanism 3 and an air supply mechanism 4 are respectively set at the air inlet 10 and the air outlet 11, and the ambient air is sucked into the heat dissipation duct 12 through the air inlet 10 by the air inlet mechanism 3, so that the ambient air dissipates the heat of the hot end of the semiconductor refrigeration unit 2 through the accommodating cavity 13, and then the heat of the hot end of the semiconductor refrigeration unit 2 is discharged through the air outlet 11 by the air supply mechanism 4, so as to achieve the heat dissipation of the hot end of the semiconductor refrigeration unit 2. Therefore, the embodiment of the present application can use the ambient temperature to ventilate and dissipate the heat of the semiconductor refrigeration unit 2, which can greatly improve the refrigeration effect of the semiconductor refrigeration unit.

[0050] As an alternative embodiment, see Figure 1 and Figure 3 The housing 1 further has a mounting opening 14 , which is connected to the heat dissipation duct 12 to form an accommodating cavity 13 .

[0051] The installation opening 14 of the embodiment of the present application is preferably opposite to the heat dissipation duct 12, that is, the installation opening 14 is located between the air inlet 10 and the air outlet 11, and the space of the accommodating cavity 13 and the space of the heat dissipation duct 12 are basically completely overlapped, which can more fully realize the heat dissipation of the semiconductor refrigeration unit 2.

[0052] As a preferred embodiment, see Figure 4 The semiconductor refrigeration unit 2 includes a semiconductor refrigeration sheet 20 and a heat dissipation fin 21 . The cold end of the semiconductor refrigeration sheet 20 faces the installation opening 14 , and the hot end faces the heat dissipation duct 12 , and is connected to the heat dissipation fin 21 .

[0053] Semiconductor cooling chips are also called thermoelectric cooling chips, which have a hot end and a cold end. When powered on, the cold end will cool, while the hot end will generate heat. In the embodiment of the present application, the cold end of the semiconductor cooling chip 20 is directed toward the mounting port 14, so that the cold end of the semiconductor cooling chip 20 is connected to a device to be cooled, such as a reagent storage device 5, so as to cool the reagent storage device 5; the heat generated by the hot end is transferred by arranging the heat dissipation fin 21 at the hot end of the semiconductor cooling chip 20, and the heat dissipation fin 21 is placed in the heat dissipation air duct 12, and the airflow in the heat dissipation air duct 12 takes away the heat on the heat dissipation fin 21, thereby achieving heat dissipation of the hot end of the semiconductor cooling chip 20 and improving the heat dissipation efficiency.

[0054] As a preferred embodiment, the heat dissipation fins 21 are arranged along the air flow direction in the heat dissipation duct 12 .

[0055] See Figure 3 The airflow direction in the heat dissipation duct 12 flows from left to right, and the heat dissipation fins 21 are also distributed from left to right, thereby increasing the contact area between the heat dissipation fins 21 and the airflow in the heat dissipation duct 12, further improving the heat dissipation efficiency.

[0056] As an optional embodiment, a plurality of semiconductor refrigeration units 2 are provided, and the plurality of semiconductor refrigeration units 2 are arranged along the air flow direction in the heat dissipation duct 12 , and the cold sides of the plurality of semiconductor refrigeration units 2 are closely attached to the bottom of the reagent storage device 5 .

[0057] The embodiment of the present application realizes efficient regulation of the temperature of the stored reagent in the reagent storage device 5 by providing a plurality of semiconductor refrigeration units.

[0058] As an alternative embodiment, see Figure 1 and Figure 3 The air inlet mechanism 3 includes a first fan 30 , and the air suction side of the first fan 30 is arranged toward the air inlet 10 .

[0059] The first fan 30 in the embodiment of the present application includes a housing and blades disposed in the housing. The front and back of the housing are respectively an air outlet side and an air suction side. The air suction side generates negative pressure toward the air inlet 10 to suck ambient air into the housing through the air inlet 10, and the air outlet side faces the heat dissipation duct 12 to blow ambient air from the air outlet side into the heat dissipation duct 12.

[0060] As a preferred embodiment, see Figure 1 The air inlet mechanism 3 also includes a dustproof structure 31 , which includes a dustproof cover 310 disposed on the air inlet 10 , and a dustproof net 311 movably disposed in the dustproof cover 310 .

[0061] Since the suction side of the first fan 30 can generate a relatively large negative pressure suction, dust in the external environment will also be sucked in. In order to prevent the inhalation of dust, the embodiment of the present application sets a dustproof structure 31 at the air inlet 10, and prevents dust from entering the air inlet 10 through a dustproof net 311; and the dustproof net 311 is movably arranged in the dustproof cover 310, which is convenient for removing the dustproof net 311 for cleaning, thereby avoiding the problem of clogging of the dustproof cover 310 and poor ventilation caused by long-term use of the air inlet 10.

[0062] As an alternative embodiment, see Figure 1 and Figure 3 The air supply mechanism 4 includes a second fan 40 , and the air outlet side of the second fan 40 is arranged toward the air outlet 11 .

[0063] The second fan 40 in the embodiment of the present application includes a housing and blades arranged in the housing. The front and back of the housing are respectively an air outlet side and an air suction side. The air suction side faces the heat dissipation air duct 12 to absorb the heat at the hot end of the semiconductor refrigeration unit 2 into the housing, and the air outlet side faces the air outlet 11 to discharge the heat at the hot end of the semiconductor refrigeration unit 2 through the air outlet 11.

[0064] As a preferred embodiment, see Figures 1 to 3 The air supply mechanism 4 further includes a guide cover 41 , which is disposed at the air outlet 11 and is used to guide the heat of the air outlet 11 in a direction away from the air inlet 10 .

[0065] In the embodiment of the present application, a deflector 41 is provided to guide the heat of the air outlet 11 away from the air inlet 10, thereby preventing the hot air blown out from the air outlet 11 from being sucked into the air inlet mechanism 3 and affecting the heat dissipation of the hot end of the semiconductor refrigeration unit 2.

[0066] Corresponding to the aforementioned application function implementation device embodiment, the present application also provides a refrigeration device and corresponding embodiments.

[0068] The refrigeration device of the embodiment of the present application performs refrigeration through the semiconductor refrigeration unit 2, and dissipates heat from the semiconductor refrigeration unit 2 through the heat dissipation device. The semiconductor refrigeration unit 2 is accommodated in the accommodating cavity 13 of the heat dissipation device. When in use, the cold end of the semiconductor refrigeration unit 2 is placed close to the equipment to be refrigerated, such as the reagent storage device 5, to refrigerate the reagent storage device 5. Since the hot end of the semiconductor refrigeration unit 2 generates heat during the refrigeration process, the embodiment of the present application dissipates heat from the hot end of the semiconductor refrigeration unit 2 through the heat dissipation device. Specifically, an air inlet 10 and an air outlet 11 can be arranged on the housing 1 at intervals along its extension direction, so as to form a heat dissipation duct 12 with a certain extension length inside the housing 1 between the air inlet 10 and the air outlet 11, so that the wind direction in the heat dissipation duct 12 is unidirectional, the air flow is continuous and unimpeded, and is not affected by airflow in other directions, which can greatly improve the heat dissipation effect; then an air inlet mechanism 3 and an air supply mechanism 4 are respectively arranged at the air inlet 10 and the air outlet 11, and the ambient air is sucked into the heat dissipation duct 12 through the air inlet 10 through the air inlet mechanism 3, so that the ambient air dissipates the heat of the hot end of the semiconductor refrigeration unit 2 through the accommodating cavity 13, and then the heat of the hot end of the semiconductor refrigeration unit 2 is discharged through the air outlet 11 through the air supply mechanism 4, so as to achieve the heat dissipation of the hot end of the semiconductor refrigeration unit 2. Therefore, the embodiment of the present application can use the ambient temperature to ventilate and dissipate the heat of the semiconductor refrigeration unit 2, which can greatly improve the refrigeration effect of the semiconductor refrigeration unit.

[0069] Corresponding to the aforementioned application function implementation device embodiment, the present application also provides a reagent storage system and corresponding embodiments.

[0071] The reagent storage system of the embodiment of the present application includes a reagent storage device 5 and a refrigeration device, and the reagent storage device 5 is refrigerated by the refrigeration device to maintain the reagent storage temperature. Among them, the cold end of the semiconductor refrigeration unit 2 in the refrigeration device is connected to the reagent storage device 5, and the reagent storage device 5 is refrigerated by the cold energy generated by the cold end of the semiconductor refrigeration unit 2. Since the hot end of the semiconductor refrigeration unit 2 generates heat during the refrigeration process, the embodiment of the present application dissipates heat from the hot end of the semiconductor refrigeration unit 2 through a heat dissipation device. Specifically, an air inlet 10 and an air outlet 11 can be arranged on the housing 1 at intervals along its extension direction, so as to form a heat dissipation duct 12 with a certain extension length inside the housing 1 between the air inlet 10 and the air outlet 11, so that the wind direction in the heat dissipation duct 12 is unidirectional, the air flow is continuous and unimpeded, and is not affected by airflow in other directions, which can greatly improve the heat dissipation effect; then an air inlet mechanism 3 and an air supply mechanism 4 are respectively arranged at the air inlet 10 and the air outlet 11, and the ambient air is sucked into the heat dissipation duct 12 through the air inlet 10 through the air inlet mechanism 3, so that the ambient air dissipates the heat of the hot end of the semiconductor refrigeration unit 2 through the accommodating cavity 13, and then the heat of the hot end of the semiconductor refrigeration unit 2 is discharged through the air outlet 11 through the air supply mechanism 4, so as to achieve the heat dissipation of the hot end of the semiconductor refrigeration unit 2. Therefore, the embodiment of the present application can use the ambient temperature to ventilate and dissipate the heat of the semiconductor refrigeration unit 2, which can greatly improve the refrigeration effect of the semiconductor refrigeration unit.

[0072] In addition, the heat dissipation device in the embodiment of the present application can be arranged at the bottom of the reagent storage device 5 to adjust the temperature of the stored reagent without affecting the taking and placing of the stored reagent.

[0074] As the semiconductor refrigeration unit 2 cools the reagent storage device 5, condensed water will be generated in the reagent storage device 5. The condensed water will gather at the bottom and then be discharged into the condensed water collection box 6 through the guide pipe 50, so as to collect the condensed water, prevent the condensed water from dripping and affecting the equipment, and avoid affecting the stability of the reagent in the reagent storage device 5.
