Description

Technical Field

[0001] This invention relates to the field of incubator technology, and more particularly to an incubator temperature equalization system and an incubator. Background Technology

[0002] An incubator is a medical device widely used to provide a clean, temperature- and humidity-controlled environment for critically ill, low-birth-weight, and premature infants. The heating unit is one of the essential functional components of an incubator.

[0003] In existing technology, the heating unit is located at the bottom of the incubator and typically includes a heating element and a centrifugal fan. The centrifugal fan is positioned between the two heating elements. When the centrifugal fan operates, it drives the air heated by the heating elements to form a vortex. This vortex moves throughout the incubator to increase the temperature. To enable the centrifugal fan to form a vortex, a partition is installed above the centrifugal fan. The lower surface of the partition protrudes downwards on both sides of the centrifugal fan to divide the space below the partition. A gas inflow channel is formed between the lower surface of the protruding part and the bottom of the incubator, used to supply air to the centrifugal fan. A gas outflow channel is formed between the side walls of the protruding part. The hot air vortex flows from the gas outflow channel into the space inside the incubator above the partition. The side walls of the protruding part on the bottom surface of the partition can block the airflow blown by the centrifugal fan from flowing into the gas inflow channel, preventing airflow turbulence. Because the hot air vortex generated by the centrifugal fan rotates in one direction, heat accumulates on one side of the gas outlet channel due to the obstruction of the protruding part of the separator, resulting in uneven temperature inside the chamber and reducing the comfort of the infant in the incubator. Summary of the Invention

[0004] This invention provides a temperature equalization system and a baby incubator, which solves the problem of uneven heat distribution in baby incubators in the prior art, which leads to a decrease in the comfort of infants.

[0005] According to a first aspect, embodiments of the present invention provide an infant incubator temperature equalization system, including an outer shell, a heating component, a centrifugal fan, a partition, and an air guide structure;

[0006] The outer casing includes a base and side plates surrounding the base. The upper surface of the base is recessed to form a gas inflow channel. The centrifugal fan is disposed above the middle of the gas inflow channel. The two heating components are disposed in the gas inflow channel and are respectively located on both sides of the centrifugal fan.

[0007] The separator is disposed above the centrifugal fan. The gas inflow channel communicates with the space above the separator. The separator protrudes downwards to form a first protrusion and a second protrusion corresponding to the positions of the two heating components. The height of the sidewalls of the first protrusion and the second protrusion is greater than or equal to the height of the air outlet area of ​​the centrifugal fan. The sidewalls of the first protrusion and the second protrusion form a gas outflow channel communicating with the space above the separator. A flow guide structure is formed on the bottom surface of the separator and is located in the gas outflow channel. The air guide structure is disposed on the side plate and is located on the outflow path of the air vortex generated by the centrifugal fan. The flow guide structure and the air guide structure are used to guide the flow direction of the air vortex and avoid excessive heat concentration.

[0008] As a further optional solution for the temperature equalization system of the incubator, the airflow guiding structure includes a first airflow guiding part and a second airflow guiding part formed by the bottom surface of the separator protruding downwards. The first airflow guiding part and the second airflow guiding part are symmetrically arranged on both sides of the centrifugal fan and are both located in the gas outflow channel. The height of the first airflow guiding part and the second airflow guiding part gradually increases along the direction of movement of the air vortex generated by the centrifugal fan.

[0009] As a further alternative to the temperature equalization system of the incubator, the width of the first guide section and the second guide section gradually increases along the direction of movement of the air vortex generated by the centrifugal fan.

[0011] As a further optional embodiment of the temperature equalization system of the incubator, a first inclined surface is also formed on the side wall of the first protrusion, the first inclined surface extending from the outside of the centrifugal fan toward the lower end of the second guide portion; a second inclined surface is also formed on the side wall of the second protrusion, the second inclined surface extending from the outside of the centrifugal fan toward the lower end of the first guide portion; the extension directions of the first inclined surface and the second inclined surface are both along the tangential direction of the centrifugal fan, and the first inclined surface and the second inclined surface are parallel to each other.

[0012] As a further optional embodiment of the infant incubator temperature equalization system, the partition includes a bottom wall and a surrounding wall. A portion of the surrounding wall protrudes outward to abut against the inner surface of the side panel, while the remaining portion of the surrounding wall is spaced apart from the inner surface of the side panel. This forms a gas inlet communicating with the gas inflow channel and a gas outlet communicating with the gas outflow channel between the surrounding wall and the inner surface of the side panel. A partition is provided above the gas outlet, and the partition is spaced apart from the side panel to form an extended flow channel. The gas outflow channel communicates with the extended flow channel through the gas outlet.

[0013] As a further optional solution for the temperature equalization system of the incubator, an air outlet is provided in the lower middle part of the partition.

[0014] As a further optional solution for the temperature equalization system of the incubator, the air guiding structure includes a plurality of air guiding plates, which are disposed in the extended flow channel and extend obliquely upward from the top of the air outlet.

[0018] The temperature equalization system of this incubator uses the relative relationship between the separator and the outer shell to construct a gas inflow channel and a gas outflow channel. Driven by a centrifugal fan, the gas flows through the gas inflow channel, passes through the heating component and the centrifugal fan in sequence, and is discharged from the gas outflow channel in the form of a vortex. The flow guiding structure and air guiding structure are set on the gas outflow path to improve the flow distribution of the outflowing gas, thereby uniformly distributing the temperature in the incubator and improving the comfort of the baby in the incubator.

The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] This invention provides a temperature equalization system and a baby incubator, which solves the problem of uneven heat distribution in baby incubators in the prior art, which leads to a decrease in the comfort of infants.

[0044] In the embodiments of the present invention, please refer to the references. Figures 1 to 8The infant incubator's temperature equalization system includes an outer shell 10, heating components 20, a centrifugal fan 30, and a partition 40. The outer shell 10 includes a base 11 and side plates 12 surrounding the base 11. The upper surface of the base 11 is recessed to form a gas inflow channel 50. The centrifugal fan 30 is positioned above the center of the gas inflow channel 50. Two heating components 20 are positioned within the gas inflow channel 50, located on either side of the centrifugal fan 30. The partition 40 is positioned above the centrifugal fan 30. The gas inflow channel 50 communicates with the space above the partition 40. The partition 40 protrudes downwards corresponding to the positions of the two heating components 20, forming a first protrusion 41 and a second protrusion 42. The height of the sidewalls of the first protrusion 41 and the second protrusion 42 is greater than or equal to the height of the air outlet area of ​​the centrifugal fan 30. The sidewalls of the first protrusion 41 and the second protrusion 42 form a gas outlet channel 60 that connects to the space above the partition 40. A flow guide structure 43 is formed on the bottom surface of the partition 40 and is located in the gas outlet channel 60. The air guide structure 90 is disposed on the side plate 12 and is located on the outlet path of the air vortex generated by the centrifugal fan 30. The flow guide structure 43 and the air guide structure 90 are used to guide the flow direction of the air vortex and avoid excessive heat concentration.

[0045] In this embodiment of the invention, the structure of the incubator including the temperature equalization system further includes a baby carrier 70 and a cover 80. The baby carrier 70 is disposed above the partition 40 and is used to carry the baby. The cover 80 covers the top of the outer shell 10 and together with the outer shell 10 forms a sealed space for accommodating the baby.

[0046] The working process of the temperature equalization system of the incubator is as follows: the centrifugal fan 30 rotates, draws in axial airflow and blows it out radially, thereby generating a pressure difference. Under the action of the pressure difference, the gas in the space above the separator 40 flows to the heating component 20 through the gas inflow channel 50. It is heated by the heating component 20 and becomes hot air. The hot air continues to flow to the centrifugal fan 30 and is discharged in the form of a vortex along the radial direction of the centrifugal fan 30. The discharged hot air is blocked by the side walls of the first protrusion 41 and the second protrusion 42 and cannot be blown into the gas inflow channel 50 (to avoid airflow turbulence). Instead, it is guided by the side walls of the first protrusion 41 and the second protrusion 42 and enters the gas outflow channel 60. It then enters the space above the separator 40 from the gas outflow channel 60 and is then redistributed in the incubator under the guidance of the air guide structure 90, thereby making the heat distribution more uniform.

[0047] Typically, the gas inlet channel 50 is located at the two short sides of the incubator, and the gas outlet channel 60 is located at the two long sides of the incubator, so as to output hot air over a longer straight range, thereby shortening the heating time. The hot air, driven by the centrifugal fan 30, has a speed that moves in a certain direction, so that when it is directly facing the bottom surface of the partition 40... Figure 6 (From a perspective) Taking the rotation direction of the centrifugal fan 30 as clockwise as an example, the air above the centrifugal fan 30 has a rightward speed, so more heat accumulates on the right side, resulting in a higher temperature. The air below the centrifugal fan 30 has a leftward speed, so more heat accumulates on the left side, resulting in a higher temperature.

[0048] The above phenomenon can be explained by the air outlet formulas for each outlet of a multi-outlet centrifugal fan. The air outlet formulas are as follows: Where Q represents the theoretical air volume of the entire centrifugal fan. Represents the exit angle. The included angle of the outlet is Air volume at that time.

[0049] For the elongated gas outlet channel 60, to simplify the analysis, one long side of the infant incubator can be evenly divided into three parts at the third division point, and each of the three parts can be considered as an air outlet. Outlet angle The quantification method is to draw a tangent from the boundary of the air outlet to the outer circle of the centrifugal fan (e.g., Figure 6 (As shown by the bold black line in the image), the angle between the radius from the point of tangency to the center of the circle is the exit angle. exist Figure 6 In the diagram, the included angles of the three air outlets are C1, C2, and C3, with C1 measuring 57.03°, C2 measuring 51.55°, and C3 measuring 67.98°. Therefore, the air outlet corresponding to C3 has the largest airflow and receives the most heat, resulting in a higher temperature.

[0050] The flow guiding structure 43, located in the gas outlet channel 60, guides the flow of hot air, reducing heat accumulation and resulting in a more uniform temperature. The flow guiding structure 43 guides the hot air flow in two ways: one is by creating flow channels of different sizes within the gas outlet channel 60—specifically, narrower channels where the flow rate is high and wider channels where the flow rate is low—resulting in varying air resistance in different areas, causing air to move from high-flow areas to low-flow areas, thus reducing heat accumulation; the other is by utilizing the shape of the flow guiding structure 43 itself to alter the airflow direction and reduce heat accumulation. It is understood that these two methods can be used in combination to achieve the same or even better results than using either method alone.

[0051] The principle behind using drag to influence the direction of hot air flow is based on Bernoulli's equation, which is as follows:

[0052]

[0053] Where P represents static pressure, v represents flow velocity, ρ represents fluid density, g is gravitational acceleration, h represents height, and C represents a constant; when the outlet size of the flow channel changes (increases or decreases), the back pressure at the outlet changes (increases or decreases), which leads to a change in static pressure (increases or decreases), and the change in static pressure leads to a change in flow velocity (decreases or increases), thus causing a change in flow rate (decreases or increases).

[0054] The purpose of the air guide structure 90 is to further guide the air that has been initially distributed by the flow guide structure 43, making the heat distribution more uniform. Therefore, the structure of the air guide structure 90 should be able to guide the flowing air from areas of high flow rate to areas of low flow rate. Since the shape of the flow guide structure 43 varies, the heat distribution after airflow is also different. Therefore, the shape and position of the air guide structure 90 need to be adapted to meet the requirements of uniform temperature. Similarly, the air guide structure 90 can also distribute airflow by increasing resistance in certain areas of the gas flow path and by using its own shape for guidance. It should be noted that although only some preferred embodiments of the flow guide structure 43 and the air guide structure 90 are listed in the following embodiments, other embodiments of the flow guide structure 43 and the air guide structure 90 different from those listed in this specification, produced by the above methods or combinations thereof, should also be considered to fall within the scope of this invention.

[0055] The temperature equalization system of the incubator uses the relative relationship between the separator 40 and the outer shell 10 to construct a gas inflow channel 50 and a gas outflow channel 60. Driven by the centrifugal fan 30, the gas can pass through the heating component 20 and the centrifugal fan 30 in sequence from the gas inflow channel 50, and be discharged from the gas outflow channel 60 in the form of a vortex. The flow guiding structure 43 and the air guiding structure 90 are set on the gas outflow path to improve the flow distribution of the outflowing gas, thereby uniformly distributing the temperature in the incubator and improving the comfort of the baby in the incubator.

[0056] In one embodiment, please refer to Figure 6 The flow guiding structure 43 includes a first flow guiding part 431 and a second flow guiding part 432 protruding downward from the bottom surface of the separator 40. The first flow guiding part 431 and the second flow guiding part 432 are symmetrically arranged on both sides of the centrifugal fan 30. The height of both the first flow guiding part 431 and the second flow guiding part 432 gradually increases along the direction of the air vortex generated by the centrifugal fan 30. Taking the clockwise rotation of the centrifugal fan 30 as an example, the height of the first flow guiding part 431 gradually increases from right to left, and the height of the second flow guiding part 432 gradually increases from left to right.

[0057] In this embodiment, the height of the first guide section 431 and the second guide section 432 makes the width of the gas outlet channel 60 narrower and the gas flow resistance greater in areas with higher flow rates, and the width of the gas outlet channel 60 wider and the gas flow resistance smaller in areas with lower flow rates. The smaller gas flow resistance allows the gas to pass through quickly, thereby creating a certain pressure difference, which causes the gas at the high flow rate to move towards the low flow rate, thereby reducing the accumulation of gas, that is, reducing the accumulation of heat.

[0058] In one specific embodiment, the widths of the first guide section 431 and the second guide section 432 gradually increase along the direction of motion of the air vortex generated by the centrifugal fan 30. Changing the width also utilizes the resistance during flow to improve airflow distribution.

[0059] In a more specific embodiment, the outer surfaces of the first guide portion 431 and the second guide portion 432 are both smooth curved surfaces, and both the first guide portion 431 and the second guide portion 432 extend along a straight line.

[0060] In one specific embodiment, the flow guiding structure 43 further includes a first arcuate surface 411 and a second arcuate surface 421. The first arcuate surface 411 is formed on the sidewall of the first protrusion 41 and extends from the outside of the centrifugal fan 30 toward the higher end of the first protrusion 41; the second arcuate surface 421 is formed on the sidewall of the second protrusion 42 and extends from the outside of the centrifugal fan 30 toward the higher end of the second flow guiding portion 432.

[0061] In this embodiment, the first arcuate surface 411 and the second arcuate surface 421 guide the direction of air vortex movement with their own shapes, thereby improving the situation of heat accumulation.

[0062] In one embodiment, a first inclined surface 412 is also formed on the sidewall of the first protrusion 41, the first inclined surface 412 extending from the outside of the centrifugal fan 30 toward the lower end of the second guide portion 432; a second inclined surface 422 is also formed on the sidewall of the second protrusion 42, the second inclined surface 422 extending from the outside of the centrifugal fan 30 toward the lower end of the first guide portion 431.

[0063] In one specific embodiment, the first inclined surface 412 and the second inclined surface 422 both extend along the tangential direction of the centrifugal fan 30, and the first inclined surface 412 and the second inclined surface 422 are parallel to each other.

[0064] The first inclined surface 412 and the second inclined surface 422 both extend along the tangential direction of the centrifugal fan 30, which can reduce the obstruction of the airflow blown out by the centrifugal fan 30 by the first inclined surface 412 and the second inclined surface 422, and reduce the impact on the airflow.

[0065] In one embodiment, please refer to the reference. Figure 5 , Figure 7 and Figure 8 The separator 40 includes a bottom wall 44 and a surrounding wall 45. A portion of the surrounding wall 45 protrudes outward to abut against the inner surface of the side plate 12, while the remaining portion of the surrounding wall 45 is spaced apart from the inner surface of the side plate 12. This forms a gas inlet 51 communicating with the gas inflow channel 50 and a gas outlet 61 communicating with the gas outflow channel 60 between the surrounding wall 45 and the inner surface of the side plate 12. A partition 100 is provided above the gas outlet 61. The partition 100 is spaced apart from the side plate 12 to form an extended flow channel 62. The gas outflow channel 60 communicates with the extended flow channel 62 through the gas outlet 61.

[0066] In one specific embodiment, the four corners of the enclosure 45 protrude outward to abut against the inner surface of the side plate 12, the gas inlet 51 is formed between the two short sides of the side plate 12 and the enclosure 45, and the gas outlet 61 is formed between the two long sides of the side plate 12 and the enclosure 45.

[0067] In one specific embodiment, an air outlet 101 is provided in the lower middle part of the partition 100. Part of the gas flowing out of the gas outlet channel 60 flows out through the air outlet 101, and part of the gas flows out through the extended flow channel 62 after being guided by the air guide structure 90.

[0068] In a more specific embodiment, the air guide structure 90 includes a plurality of air guide plates 91, which are disposed in the extended flow channel 62 and extend obliquely upward from the top of the air outlet 101.

[0069] In a further specific embodiment, four air guide plates 91 are provided, two of which are disposed on the first wall 121 of the side plate 12, and the other two are disposed on the second wall 122 of the side plate 12. The first wall 121 and the second wall 122 are two opposite walls on the side plate 12. Specifically, the bottom ends of the two air guide plates 91 disposed on the same wall are close to each other, while the top ends are far apart from each other.

[0070] In one embodiment, the heating assembly 20 includes a heating rod (not shown), a heat sink 21, and fins 22 disposed on the heat sink 21. The heating rod is disposed on the lower surface of the heat sink 21, and a plurality of fins 22 are spaced apart and erected on the upper surface of the heat sink 21, with the fins 22 radially distributed around the centrifugal fan 30.

[0071] In one embodiment, please refer to Figure 5 The upper surface of the separator 40 is provided with a handle 46 to facilitate the taking and putting away of the separator 40.

[0072] In one specific embodiment, two handles 46 are provided. The bottom wall 44 of the separator 40 is recessed downward to form a first protrusion 41 and a second protrusion 42 on the lower surface of the bottom wall 44, while a groove is formed on the upper surface. The two handles 46 are disposed in the groove, and the height of the handles 46 is less than or equal to the depth of the groove.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
