Technical Field
[0001] This utility model relates to the field of medical heating technology, specifically to a heating system based on biomimetic honeycomb flow guidance. Background Technology
[0002] Plasma is a commonly used blood product in medicine. It typically needs to be frozen and thawed to near body temperature before use. Excessive heat can denature plasma proteins, while insufficient heat can affect injection and the activity of active factors. Currently, traditional plasma heating typically uses a water bath method. However, water bath heating requires immersing multiple plasma bags in constant-temperature water, resulting in surrounding water pressure exceeding the pressure inside the plasma bags. This can lead to contaminants entering the plasma bags, especially if the bags are poorly sealed, increasing the risk of bacterial or other pathogen contamination. Therefore, hot air heating is gradually replacing water bath heating. However, conventional hot air heating uses a hot air blower directly towards the area where the plasma bags are suspended. The hot airflow rapidly passes over the surface of the plasma bags, causing heat exchange between the plasma bags and the airflow in the inner laminar flow near the bags, while the outer laminar flow further away from the plasma has difficulty exchanging heat with the bags. This means that the utilization rate of the hot airflow per unit time decreases, affecting the heating rate of the plasma. Furthermore, increasing the airflow temperature can easily lead to localized overheating, affecting the activity of the plasma.
[0003] Therefore, although the existing hot air heating method has solved the problem of high pollution risk by replacing water bath heating, the hot air flow generated by hot air heating usually only exchanges heat with the inner layer of the plasma bag due to the high flow of the air, while the outer layer of the air rarely participates in heat exchange on the surface of the plasma bag. This results in a low heat exchange utilization rate of the hot air flow, which affects the speed of hot air heating of the plasma bag. Utility Model Content
[0004] The purpose of this invention is to provide a heating system based on biomimetic honeycomb airflow to solve the technical problem in the prior art where, in conventional hot air heating, only the inner layer of the airflow exchanges heat with the plasma bag, while the outer layer of airflow rarely participates in heat exchange on the surface of the plasma bag, resulting in low heat exchange utilization of the hot airflow and affecting the speed of hot air heating the plasma bag.
[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: A heating system based on biomimetic honeycomb airflow guidance includes: A ring-shaped air duct, which is composed of two horizontal sections at the top and bottom and two curved sections at the left and right. A fan is installed on the upper horizontal section of the annular duct, and a heating element is provided on the air intake side of the fan to form an annular hot airflow inside the annular duct. A baffle plate is installed on the upper horizontal section of the annular air duct and located on the exhaust side of the fan, and the baffle plate is evenly and densely covered with multiple honeycomb holes; Multiple plasma bags are suspended by hooks on the exhaust side of the annular air duct. The guide plate disperses the hot airflow into multiple streams through the honeycomb holes, forming turbulence on the surface of the plasma bags to heat the plasma inside.
[0006] As a preferred embodiment of the present invention, the guide plate includes multiple layers, which are installed in parallel to each other. Each layer is densely covered with multiple honeycomb holes, and the honeycomb holes on adjacent layers are staggered.
[0007] As a preferred embodiment of the present invention, the guide plate further includes a plate frame, and a plurality of the layer plates are sequentially installed on the plate frame at a fixed interval, and the plate frame is installed on the inner wall of the upper horizontal section of the annular air duct.

Furthermore, multiple slots and covers are sequentially arranged along the direction of airflow to simultaneously suspend and heat multiple plasma bags.
[0010] As a preferred embodiment of this utility model, the cover plate is arc-shaped and matches the arc of the upper horizontal section of the annular air duct.

[0015] 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.
[0016] like Figure 1 As shown, this utility model provides a heating system based on biomimetic honeycomb flow guidance, comprising: Circular duct 1 is composed of two horizontal sections (upper and lower) and two curved sections (left and right). Fan 2 is installed on the upper horizontal section of the annular duct 1, and a heating element 21 is provided on the air intake side of fan 2 to form an annular hot airflow in the annular duct 1. The guide plate 3 is installed on the upper horizontal section of the annular air duct 1 and located on the exhaust side of the fan 2, and the guide plate 3 is evenly and densely covered with multiple honeycomb holes 311. Multiple plasma bags are suspended on the exhaust side of the annular duct 1 by hooks 41. The guide plate 3 disperses the hot airflow into multiple streams through the honeycomb holes 311 to form turbulence on the surface of the plasma bags, so as to heat the plasma inside the plasma bags.
[0017] The present invention aims to generate circulating hot airflow by installing a fan 2 with a heating element 21 inside an annular duct 1, and installing a guide plate 3 with honeycomb holes 3 on the exhaust side of the fan 2 to disperse the hot airflow into multiple airflows, so as to form turbulence on the surface of the plasma bag suspended inside the annular duct 1, thereby achieving rapid heat exchange and increasing the heating rate of the plasma bag.
[0018] Specifically: The heating element 21 consists of an array of multiple PTC ceramic heating modules. It heats up based on the temperature set by the host. The airflow drawn in by the intake side of the fan 2 is heated into hot airflow by the heating element 21. The hot airflow is blown forward by the fan 2 to the guide plate 3. After passing through multiple honeycomb holes 311 on the guide plate 3, the hot airflow is divided into multiple streams. The multiple streams continue to impact the surface of the plasma bag and collide with each other, generating turbulence on the surface of the plasma bag. The turbulence increases the heat exchange rate between the airflow and the plasma bag, thereby improving the heat exchange rate between the hot airflow and the plasma bag and realizing the rapid heating of the plasma bag.
[0019] Compared to conventional hot air heating, this invention disperses the hot airflow into multiple streams that impact the surface of the plasma bag, creating turbulence on the surface to improve heat exchange efficiency and thus increase the heating speed.
[0020] In addition, the annular duct 1 allows the airflow to circulate continuously inside, without introducing air from the complex external environment, reducing germ contamination, and reducing the heat required to reheat the airflow, thus lowering energy consumption.
[0021] Furthermore, the interior of the annular duct 1 can be coated with a sterilization coating, such as a silver ion coating, to reduce bacterial contamination. The annular duct 1 is a modular structure, allowing for complete disassembly, cleaning, and disinfection. The vertical structure of the annular duct 1 allows condensate from frozen plasma bags to be transported with the airflow to the lower horizontal section, thus avoiding impact on the heating element 21 and the fan 2. Moreover, after disassembling the annular duct 1, the condensate can be completely removed.
[0022] Although the honeycomb holes 311 on the guide plate 3 can achieve the function of diverting and guiding the flow, the multiple airflows generated by the honeycomb holes 311 diverting the flow on the guide plate 3 are blown out horizontally and at a relatively high speed. As a result, the airflows on the surface of the plasma bag will collide with each other and generate turbulence, which will quickly pass through the plasma bag and move away, making it difficult for a large number of turbulent areas to exchange heat around the plasma bag.
[0023] Therefore, as Figure 2As shown, the guide plate 3 includes multiple layers 31, which are installed in parallel to each other. Each layer 31 is densely covered with multiple honeycomb holes 311, and the honeycomb holes 311 on two adjacent layers 31 are staggered.
[0024] In this embodiment, by setting the guide plate 3 as a honeycomb-like structure composed of multiple layers 31 with honeycomb holes 31, and staggering the honeycomb holes 311 on adjacent layers 31, the airflow velocity can be effectively reduced when the airflow passes through.
[0025] Furthermore, due to the obstruction of multiple layers 31, the airflow generates turbulence inside the guide plate 3, thereby causing the airflow discharged from the guide plate 31 to form a turbulent area at the outlet and cover the entire area where the plasma bag is suspended, thereby increasing the heating speed of the plasma bag by the hot airflow.
[0026] Furthermore, such as Figure 2 As shown, the guide plate 3 also includes a plate frame 32, and multiple layers 31 are installed on the plate frame 32 at fixed intervals. The plate frame 32 is installed on the inner wall of the upper horizontal section of the annular air duct 1.
[0027] In this embodiment, the layer plates 31 are installed sequentially at fixed intervals using the plate frame 32. This not only achieves the fixed interval installation according to the simulation design requirements (the simulation design before production ensures that the turbulent area of the airflow covers the hanging area of the plasma bag, which is a conventional design process and will not be elaborated further), but also enables the overall assembly and disassembly of the guide plate 3, thereby avoiding the impact of airflow distribution caused by the spacing change due to independent installation.
[0028] Furthermore, such as Figure 2 As shown, each honeycomb hole 311 of the guide plate 3 is provided with multiple protrusions 312, and the multiple protrusions 312 are evenly distributed on the inner wall of the honeycomb hole 311.
[0029] In this embodiment, the inner wall of the honeycomb hole 311 is provided with protrusions 312. When the airflow passes through, it will collide with the protrusions 312, thereby generating the Karman vortex street phenomenon. That is, a single airflow will be dispersed into continuous and alternating airflow vortices. After passing through the guide plate 3, the collision between the airflow vortices can form more complex turbulence in the suspension area of the plasma bag, further increasing the heating speed.
[0030] Among them, the Karman vortex street is an important phenomenon in fluid mechanics and can often be encountered in nature. When a steady flow passes around certain objects under certain conditions, double rows of linear vortices with opposite rotation directions and regular arrangement will periodically fall off on both sides of the object. After nonlinear action, the Karman vortex street is formed.
[0031] Based on the above embodiments, the plasma bags are manually suspended inside the annular duct 1. To facilitate the suspension of the plasma bags, the following preferred embodiments are provided.
[0032] like Figure 3 As shown, it also includes a cover plate 4, which has a slot on the upper side of the peripheral wall of the upper horizontal section of the annular air duct 1. The slot is located on the exhaust side of the fan 2, and the cover plate 4 is detachably installed on the slot, and the hook 41 is installed on the bottom of the cover plate 4. Furthermore, multiple slots and cover plates 4 are sequentially arranged along the direction of airflow to simultaneously suspend and heat multiple plasma bags.
[0033] In this embodiment, the annular duct 1 has multiple slots on the exhaust side of the fan 2, and each slot is covered with a cover plate 4. A hook 41 is installed at the bottom of the cover plate 4. When it is necessary to hang the plasma bag, after the cover plate 4 is removed, the plasma bag is installed on the hook 41, and the cover plate 4 is put back on the slot. The plasma bag is then suspended on the exhaust side of the fan 2 inside the annular duct 1.
[0034] Furthermore, such as Figure 4 As shown, the cover plate 4 is arc-shaped and matches the arc of the upper horizontal section of the annular air duct 1. Multiple threaded holes 42 are provided on the cover plate 4 along its arc wall. Threaded hanging rods 421 are installed in the threaded holes 42, and hooks 41 are installed at the bottom of the hanging rods 421. The height of the hook 41 can be adjusted by rotating the threaded rod 421, so that the multiple hooks 41 are staggered in height and back, and the multiple plasma bags are staggered in distribution within the annular duct 1.
[0035] In this embodiment, the hook 41 is installed on the threaded rod 421, and the threaded rod 421 is installed in the threaded hole 42 provided on the cover plate 4. By rotating the threaded rod 421, the height of the hook 41 and the plasma bag suspended on it can be adjusted. In other words, multiple plasma bags can be adjusted to be staggered in height, thereby avoiding the plasma bags from blocking the airflow and enabling multiple plasma bags to be heated quickly.
[0036] Furthermore, the annular duct 1 of the plasma bag suspension area can be made of transparent material, so that it can be observed and adjusted so that the thin side of the plasma bag faces the airflow direction, and the turbulence generated by the airflow flows through the two side walls with the largest area of the plasma bag.
[0037] It should be noted that the temperature control of the heating component 21 is completed by the host, and a temperature sensor connected to the host is also installed on the exhaust side of the fan 2 to effectively monitor the airflow temperature. The host can adjust the temperature of the heating component 21 according to the monitored airflow temperature to keep the airflow temperature within the set temperature threshold range. For example, if the temperature is set to 35℃ and the threshold is ±1℃, the airflow temperature can be maintained at 34~36℃. This is a conventional temperature control technique and will not be elaborated further.
[0038] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
