In one embodiment of the reagent refrigerating apparatus provided in the present invention, please refer to fig. 1 to 8, which include a cooling chamber main body 2, a refrigerating element 4, a heat dissipation element and a fan 5.

A refrigerating chamber 21 is provided in the cold chamber main body 2, and the refrigerating chamber 21 is used as a storage space for the reagent bottles 1, and the reagent bottles 1 are filled with reagents such as CRP latex reagents.

The cooling element 4 is fixed to the cold chamber body 2. The refrigerating element 4 is an energy conversion device and has a cold end and a hot end, and the cold end of the refrigerating element 4 faces the refrigerating chamber 21 to cool the refrigerating chamber 21, so that the reagent is cooled for refrigeration.

The fan 5 and the heat radiating member are disposed in the heat radiating housing 3. The heat dissipation housing 3 is located outside the cooling chamber main body 2, and in practical application, the heat dissipation housing 3 is located below the cooling chamber main body 2. As shown in fig. 4, the heat dissipating housing 3 is connected to the outside through the air inlet 32 and the air outlet 31. The cold end of the heat dissipation element is connected to the hot end of the refrigeration element 4, the cold end of the heat dissipation element absorbs the heat at the hot end of the refrigeration element 4, and the heat on the heat dissipation element is conducted from the cold end to the hot end. The fan 5 can provide cold air to the hot end of the heat dissipation element to forcibly cool the hot end of the heat dissipation element, so that heat on the hot end of the heat dissipation element is quickly dissipated. When the fan 5 works, the air is driven to flow to the air outlet 31 along the air inlet 32 and the hot end of the heat dissipation element in sequence, and the cold end of the heat dissipation element is arranged in a second space 39 outside the first space 38 where an air flow path between the hot end of the heat dissipation element and the air outlet 31 is located.

Different spaces in the heat dissipation housing 3 refer to different regions which are not overlapped with each other, and adjacent spaces can be communicated or isolated. The boundaries of the spaces may be defined by solid structures such as plates, or may not be provided with solid structures, for example, the inner cavity of the heat dissipation housing 3 is a rectangular cavity, the left end surface of the heat dissipation housing 3 is provided with the air outlet 31, the right end surface is provided with the air inlet 32, the left half space in the heat dissipation housing 3 is the first space 38, and the right half space is the second space 39, so that the fan 5 guides air flow from the air inlet 32 through the second space 39, the first space 38, and the air outlet 31, even if no solid separation structure is particularly provided between the first space 38 and the second space 39, the air flow into the first space 38 and then towards the air outlet 31 can be realized without flowing to the second space 39 where the cold end of the heat dissipation element is located, only by the guidance of the fan 5 and the inner wall of the heat dissipation housing 3.

In this embodiment, when the fan 5 operates, after the air is driven to cool the hot end of the heat dissipation element, the generated hot air sequentially passes through the air flow path between the hot end of the heat dissipation element and the air outlet 31, and the air outlet 31 is discharged outside the heat dissipation housing 3, and because the cold end of the heat dissipation element is not in the air flow path, the cold end of the hot air generated by air cooling of the hot end of the heat dissipation element in the heat dissipation housing 3 can be reduced or avoided, and the shielding effect of the heat dissipation housing 3 can also reduce or avoid discharging the cold end of the hot air outside the heat dissipation housing 3 to secondarily heat the heat dissipation element, which is beneficial to ensuring the heat dissipation capability of the cold end of the heat dissipation element on the refrigeration element 4.

Further, as shown in fig. 4 and 5, a baffle 36 is disposed in the heat dissipation housing 3, the cold end and the hot end of the heat dissipation element are disposed on two sides of the baffle 36, respectively, and the middle of the heat dissipation element penetrates through the baffle 36. Baffle 36 blocks between the cold and hot ends of the heat dissipating component to effectively prevent hot air from flowing to the cold end of the heat dissipating component.

Further, as shown in fig. 4, there is a gap between the cold end of the heat dissipating element and the baffle 36. That is to say, radiating element's cold junction does not have the direct contact relation with baffle 36, compares in radiating element's cold junction and baffle 36 have the embodiment of direct contact, and this embodiment can reduce the solid heat conduction of baffle 36 and radiating element cold junction, reduces the temperature influence of baffle 36 to radiating element's cold junction.

Further, as shown in fig. 4 and 5, the baffle 36 is provided with a vent 310, and when the fan 5 is in operation, the air is driven to flow to the air outlet 31 along the air inlet 32, the cold end of the heat dissipation element, the vent 310, and the hot end of the heat dissipation element in sequence. At this time, the second space 39 is an air inlet duct, the first space 38 is an air outlet duct, and air flows from the air inlet 32, the second space 39, and the first space 38 to the air outlet 31. Because the air inlet duct is used for providing the lower gas of temperature, directly set up the cooling element cold junction in the air inlet duct, can be so that the cooling element is with the help of gaseous cooling to a certain extent. In this embodiment, only two spaces, namely the first space 38 and the second space 39, are provided in the heat dissipation housing 3, and are particularly partitioned by the baffle 36, so that the heat dissipation housing is convenient to process. In the orientation shown in fig. 4, the first space 38 is defined by a portion of the wall surface of the heat-dissipating housing 3 and the baffle 36, and the remaining portion of the heat-dissipating housing 3 is the second space 39.

Further, the fan 5 is arranged at the ventilation opening 310, so that the baffle 36 can be used for wind shielding and heat insulation, and the fan 5 can be installed, the versatility of the baffle 36 can be realized, and the assembly of the whole machine is convenient. Optionally, the fan 5 and the hot end of the heat dissipation element are respectively disposed at two sides of the baffle 36, as shown in fig. 4, the fan 5 is disposed outside the first space 38, preferably, the outer contour of the fan 5 is fitted to the ventilation opening 310, and then the housing of the fan 5 is hermetically connected to the ventilation opening 310, so that the air entering the ventilation opening 310 is low-temperature air introduced under the guidance of the fan 5, and no gap exists between the ventilation opening 310 and the housing of the fan 5, thereby preventing the hot air in the first space 38 from flowing back to the second space 39.

Further, as shown in fig. 4 and 5, the wall surface of the baffle 36 provided with the vent 310 and the wall surface of the heat dissipation housing 3 provided with the air outlet 31 are arranged in parallel, and the vent 310 and the air outlet 31 are arranged oppositely, so that the first space 38 forms a linear air duct, and after being blown to the hot end of the heat dissipation element through the vent 310 under the guidance of the fan 5, the air can substantially linearly flow out of the heat dissipation housing 3 along the entering direction without turning, thereby improving the hot air discharging efficiency.

Further, as shown in fig. 3 and 8, in order to prevent the wind from directly flowing back to the air inlet 32 from the air outlet 31, an air outlet guide cover 311 is covered on the outer side of the air outlet 31, the air outlet guide cover 311 is fixed on the outer side of the heat dissipation housing 3, and the air outlet guide cover 311 extends from the covering position towards the direction far away from the air inlet 32, so that the air outlet of the air outlet 31 flows towards the direction far away from the air inlet 32, thereby preventing the hot wind from flowing out of the air outlet 31, i.e., directly flowing back to the air inlet 32 for reuse.

Further, referring to fig. 6, the cold end of the heat dissipation element includes a heat dissipation base 34 and the hot end includes a heat dissipation fin 37, and the heat dissipation base 34 is attached to the hot end of the refrigeration element 4. The heat dissipation base 34 is specifically a copper base, and is manufactured by machining or die casting, and the copper base has a high heat dissipation coefficient and is directly in contact with the hot end of the refrigeration element 4, so that heat at the hot end of the refrigeration element 4 can be rapidly transferred to the copper base, and in other embodiments, the copper base may be another metal base with strong thermal conductivity. The heat dissipation fins 37 are made of copper or aluminum plate, and the area and number of the heat dissipation fins 37 should be increased as much as possible on the premise that the space allows, so as to ensure the heat dissipation rate of the refrigeration element 4. The heat dissipation device further comprises a heat pipe 33, wherein an evaporation end of the heat pipe 33 is connected to the heat dissipation base 34 and a condensation end of the heat pipe 33 is connected to the heat dissipation fin 37. The heat pipe 33 is a heat transfer element that transfers heat by means of phase change of its internal working fluid, and can rapidly transfer heat from the heat sink base 34 to the heat dissipation fins 37 by utilizing its internal capillary heat dissipation effect.

In this embodiment, different shapes can be manufactured by using the advantage that the heat pipe 33 is easy to manufacture different shapes, so that the position of the heat dissipation fin 37 can be flexibly arranged according to the characteristics of the structural layout, the requirement that the position of the heat dissipation fin 37 is far away from the refrigeration element 4 can be easily realized, the structural layout can be compact by adjusting the shape of the heat pipe 33, and the modularization and miniaturization of equipment are facilitated. Based on the orientation shown in fig. 4, in the heat dissipation case 3, the fan 5 is disposed above the first space 38, and the first space 38 and the fan 5 occupy the left space of the heat dissipation case 3, whereas based on the flexibility of the heat pipe 33, the middle portion thereof is bent in an L-shape, extending in the remaining right side of the heat dissipation case 3 to connect the heat base and the heat dissipation fins 37.

In addition, in other embodiments, the heat pipe 33 may be replaced with another heat conducting structure, such as a copper pipe, but the advantage of high heat conductivity of the heat pipe 33 in this embodiment is that rapid heat conduction can be achieved even when the heat radiating base 34 and the heat radiating fins 37 are far apart, which is a preferable heat conducting structure.

Further, as shown in fig. 3, at least two reagent bottle mounting locations 212 are provided in the refrigerating compartment 21, so that the refrigerating compartment 21 can be used for mounting positioning of at least two reagent bottles 1. The refrigerating chamber 21 is provided with reagent suction passages 211 corresponding to the reagent bottle mounting positions 212 in a penetrating manner, and after the reagent bottles 1 are mounted in the reagent bottle mounting positions 212, the bottle openings of the reagent bottles 1 are aligned with the corresponding reagent suction passages 211, and a sampling needle can extend into the reagent bottles 1 through the reagent suction passages 211 to suck reagents. The refrigerating chamber 21 is provided with a structure capable of refrigerating at least two reagent bottles 1, so that the high-efficiency refrigerating capacity of the reagent refrigerating device can be fully utilized. Of course, in other embodiments, only one reagent bottle mounting site 212 may be provided in the refrigerated compartment 21.

The working principle of the reagent refrigerating device provided by the embodiment is as follows: the cold end of the heat pipe 33 is directly connected with the heat dissipation base 34, the heat on the heat dissipation base 34 is transferred to the hot end of the heat pipe 33 through the capillary heat dissipation effect of the heat pipe 33, the heat on the hot end of the heat pipe 33 is quickly transferred to the heat dissipation fins 37, and thus the heat on the hot end of the refrigeration element 4 is finally transferred to the heat dissipation fins 37 through the heat dissipation base 34 and the heat pipe 33; meanwhile, in the heat dissipation housing 3, the wind guided by the fan 5 sequentially flows through the second space 39 where the heat dissipation base 34 is located to the first space 38 where the heat dissipation fins 37 are located, and the heat in the first space 38 is dissipated from the air outlet 31 along with the wind flow, so that the heat dissipation fins 37 can be prevented from reversely heating the heat dissipation base 34.

In the reagent refrigerating device provided by the embodiment, the heat dissipation base 34 and the heat dissipation fins 37 are sequentially arranged along the air flow path guided by the fan 5, so that the quality of cold air can be ensured, and the cold air is favorable for quickly taking away heat on the heat dissipation fins 37; the heat pipe 33 conducts heat between the heat dissipation base 34 and the heat dissipation fins 37, so that the heat of the refrigeration element 4 can be quickly transferred to the first space 38 far away from the refrigeration element 4 for heat dissipation, the refrigeration capacity is strong, and multiple reagents can be refrigerated at the same time under the condition of not increasing the cost and the space; the device also has the advantages of simple and compact structure, low cost, low noise and the like.

Obviously, in other embodiments, at least three spaces may be disposed in the heat dissipation housing 3 according to actual needs, and at this time, the second space 39 where the cold end of the heat dissipation element is located may not be used as the air inlet duct. For example, the air inlet duct is disposed in a third space different from the first space 38 and the second space 39, and the fan 5 enters the first space 38 from the air inlet 32 and the third space and flows to the air outlet 31, but does not flow through the second space 39.

Obviously, the fan 5 is not limited to being mounted on the baffle 36 according to the above-described embodiment. In other embodiments, the position of the fan 5 may be changed, so that the ventilation openings 310 on the fan 5 and the baffle 36 are respectively located at two sides of the hot end of the heat dissipation device, so that the air flows to the hot end of the heat dissipation device through the ventilation openings 310 in sequence, then flows to the air outlet 31 after flowing through the fan 5.

In addition, in order to prevent the wind from flowing back to the wind inlet 32 from the wind outlet 31, in other embodiments, a wind inlet guide cover may be covered on the outer side of the wind inlet 32 and extend from the covering position toward the direction away from the wind outlet 31, and at this time, the wind entering the wind inlet 32 flows in from the direction away from the wind outlet 31.
