Description

Technical Field

[0001] This utility model relates to the field of blood refrigerators, and in particular to an air duct structure for a pharmacy refrigerator. Background Technology

[0002] Blood refrigerators are specialized refrigeration equipment designed specifically for storing blood and blood products. They prevent temperature fluctuations from affecting blood quality and are widely used in hospitals, blood banks, and other places to ensure the safety and effectiveness of blood during storage and transportation.

[0003] Blood refrigerators require the use of air ducts to transport cold air. Traditional air ducts are mostly straight-line designs with a single air outlet, which can cause cold air to concentrate and impact local areas, resulting in uneven heating and cooling within the refrigerator. This cannot ensure that the blood is kept at a suitable storage temperature in all areas of the refrigerator, and the blood may deteriorate due to temperature differences. To address these issues, we propose an air duct structure for pharmacy refrigerators. Utility Model Content

[0004] The purpose of this invention is to provide an air duct structure for a pharmacy refrigerator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pharmacy refrigerator air duct structure includes a cabinet, an air duct plate inside the cabinet, two circular fan inlets on one side of the air duct plate, a bottom airflow duct between the bottom surface of the air duct plate and the inner wall of the cabinet, and two sets of circular guide holes on one side of the air duct plate.

[0007] In a further embodiment, a first threaded fixing seat is fixedly connected to the inner top wall of the box, and two second threaded fixing seats are fixedly connected to the inner wall of the box.

[0008] In a further embodiment, two positioning blocks are fixedly connected to the inner wall of the housing, and two sets of positioning protrusions are provided on the outer surface of the air duct plate. The side of the two sets of positioning protrusions that are close to each other are in contact with the outer surfaces of the two positioning blocks respectively.

[0009] In a further embodiment, an upper guide plate is fixedly connected to the inner wall of the box, and a lower guide plate is fixedly connected to the inner wall of the box. The upper guide plate and the lower guide plate have the same size and specifications.

[0010] In a further embodiment, two sets of fan fixing slots are provided on one side of the air duct plate, and the inner walls of both sets of fan fixing slots are threaded.

[0011] In a further embodiment, a first fixing hole and two second fixing holes are respectively provided on one side of the air duct plate. A fixing screw is provided on one side of each of the two second fixing holes, and the outer surface of the fixing screw is adapted to the inner wall of the second threaded fixing seat.

[0012] In a further embodiment, an arc-shaped flow guide area is provided on one side of the air duct plate, and the arc-shaped flow guide area is located below the air inlet of the circular fan.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device, through two circular fan inlets at the top and in conjunction with the lower air duct plate, can forcibly split the cold source into multiple uniform airflows. Guided by dense circular guide holes, the lower guide plate, and the bottom airflow duct, it can form a uniform airflow inside the cabinet. Compared with traditional designs, it does not rely on high-power fans. Through structural optimization alone, it can achieve uniform coverage and circulation of cold air, improving temperature uniformity while saving energy. It solves the problem of local temperature difference caused by unreasonable airflow organization in traditional air ducts, ensuring that blood is kept at a stable and suitable storage temperature in all areas of the refrigerator, reducing the risk of blood deterioration due to temperature differences.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 In this utility model, a pharmacy refrigerator air duct structure includes a box body 1, an air duct plate 2 inside the box body 1, two circular fan inlets 3 on one side of the air duct plate 2, a bottom airflow duct 16 between the bottom surface of the air duct plate 2 and the inner wall of the box body 1, two sets of circular guide holes 6 on one side of the air duct plate 2, and the double circular fan inlets 3 at the top of the air duct plate 2, based on the fluid distribution principle, can equally divide the cooling capacity of the refrigeration end to form a symmetrical cold airflow duct. The array of circular guide holes 6, using the seepage effect, can disperse the concentrated cold flow and transform it into uniform surface air supply.

[0023] In a further embodiment, a first threaded fixing seat 8 is fixedly connected to the inner top wall of the housing 1, two second threaded fixing seats 13 are fixedly connected to the inner wall of the housing 1, two positioning blocks 11 are fixedly connected to the inner wall of the housing 1, two sets of positioning protrusions 10 are provided on the outer surface of the air duct plate 2, and the side of the two sets of positioning protrusions 10 that are close to each other respectively contacts the outer surface of the two positioning blocks 11. A first fixing hole 9 and two second fixing holes 14 are respectively opened on one side of the air duct plate 2, and a fixing screw 15 is provided on one side of each of the two second fixing holes 14. Two second threaded fixing seats 13 are fixedly connected to the inner wall of the housing 1, and the outer surface of the fixing screw 15 is adapted to the inner wall of the second threaded fixing seat 13. Through the cooperation of the positioning block 11 and the positioning protrusion 10, and the connection of the first fixing hole 9, the second fixing hole 14 and the first threaded fixing seat 8, the second threaded fixing seat 13, the stability of the air duct structure during operation is ensured.

[0024] In a further embodiment, an upper guide plate 7 and a lower guide plate 4 are fixedly connected to the inner wall of the housing 1. The upper guide plate 7 and the lower guide plate 4 have the same size and specifications. Two sets of fan fixing slots 12 are opened on one side of the air duct plate 2. The inner walls of the two sets of fan fixing slots 12 are threaded. The threaded structure of the fan fixing slots 12 can provide a stable foundation for the installation of the fan and ensure the stability of the air supply. An arc-shaped guide area 5 is provided on one side of the air duct plate 2. The arc-shaped guide area 5 is located below the circular fan inlet 3. The arc-shaped guide area 5 can guide the airflow blown out by the fan, further optimize the airflow distribution, and reduce eddies and dead angles. The lower guide plate 4 forms a folded edge structure and cooperates with the upper guide plate 7 to guide the airflow to form a specific flow path in the housing 1. The bottom airflow duct 16 between the bottom surface of the air duct plate 2 and the inner wall of the housing 1 can form a closed circulation flow field, ensuring the uniformity and stability of the temperature field inside the housing.

[0025] The working principle of this utility model is as follows: First, the double circular fan inlet 3 at the top of the air duct plate 2, based on the fluid distribution principle, divides the cooling capacity of the cooling end equally to form a symmetrical cold air flow channel. Then, the array of circular guide holes 6 in the middle disperses the concentrated cold flow using the seepage effect, transforming it into a uniform surface air supply, eliminating the local temperature difference caused by the impact of the air jet. Next, the lower guide plate 4 forms a folded edge structure, and through the bottom air flow channel 16 between the box 1 and the air duct plate 2, a closed circulation flow field is formed. With the help of forced convection heat transfer, the temperature gradient inside the box 1 can be controlled within a very small range. It can build a complete temperature homogenization system from air supply, air distribution to return air circulation, ensuring a uniform and stable temperature field inside the box.
