[0015] In addition, the description such as "first", "second" and the like in the utility model is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one feature.
[0016] As Figures 1-3The utility model discloses a baby radiation warm platform inclined illumination heater, including heater shell 1 and setting in heater shell 1 with the heating source 3 of reflector 2.
[0017] Specifically, heater shell 1 is by the upper casing 1.1 of inclination fixed on baby radiation warm platform and the lower casing 1.2 buckle and form, the upper casing 1.1 is uniformly distributed with the heat dissipation hole 4 of horizontal bar structure, the heat dissipation hole 4 inboard mouth along two long sides has chamfer structure, can make heat better gather to the heat dissipation hole 4 in, accelerate heat dissipation, can also keep the outside of upper casing 1.1 with a good appearance simultaneously.
[0018] The lower casing 1.2 is set up with the irradiation window 5 of being located in reflector 2 inboard and being opposite heating source 3, when heater shell 1 is fixed on baby radiation warm platform, the irradiation window 5 just should be towards baby bed of baby radiation warm platform, can make the heat of heating source 3 under the reflection of reflector 2, pass through the irradiation window 5 and be illuminated on baby bed, realize the uniform heating of baby bed.
[0019] Between reflector 2 and upper casing 1.1 be set in the flow guide plate 6 of being located in the inner chamber of heater shell 1, the flow guide plate 6 is arc structure, its front edge gap is fixed on the inclined upper end of lower casing 1.2, and the rear edge is top-pasted to the inner wall middle part of upper casing 1.1, thereby the inner chamber of heater shell 1 above reflector 2 is divided into the heat dissipation chamber 7 of upper part and the flow guide chamber 8 of lower part.
[0020] When actually installing, can be in the circumferential adaptation of the inboard mouth of irradiation window 5 and set up a fixed frame 9, the fixed frame 9 is set up with the first isolation column 10 for connecting reflector 2, and the second isolation column 11 for connecting the front edge of flow guide plate 6, the first isolation column 10 and the second isolation column 11 are all cylindrical structure, and the upper surface center has internal thread connection hole.
[0021] Through the first isolation column 10, the contact area of reflector 2 fixed on it and fixed frame 9 can be reduced, thereby reducing heat conduction, and reducing the heating of lower casing 1.2, through the second isolation column 11, the front edge of flow guide plate 6 fixed on it and fixed frame 9 can produce a certain gap, at this time, when heating source 3 is opened and heated, a part of heat generated in the process of gradually rising will flow along flow guide chamber 8 to the inclined lower end of entire heater shell 1, and a part of heat will also diffuse from the gap between the front edge of flow guide plate 6 and fixed frame 9 to heat dissipation chamber 7, thereby making the convection heat generated when heating source 3 works can be as evenly as possible on the top of reflector 2, reducing heat accumulation, effectively avoiding the phenomenon of local temperature rise on entire heater shell 1.
[0022] For the convenience of fixing the reflector 2, a third isolation column 12 can be arranged on the left and right edges of the fixed frame 9, which has the same structure as the first and second isolation columns 10 and 11, and is connected with a pair of parallel installation vertical plates 13. At this time, the heating source 3 passes through the two installation vertical plates 13, and the main part of the heat generated when the heating source 3 is turned on is located between the two installation vertical plates 13, and the reflector 2 is inserted between the two installation vertical plates 13, thereby forming a cover body through the reflector 2 and the installation vertical plates 13, which is arranged on the heating source 3, so as to ensure that as much heat as possible generated when the heating source 3 is turned on can be gathered in the cover body, and then reflected by the reflector 2 to the baby bed.
[0023] In addition, a pair of connecting angle plates 14 can be fixed on the upper edges of the two installation vertical plates 13, and a connecting frame 15 for fixing the end of the heating source 3 and a supporting frame 16 for supporting the rear edge of the flow guide plate 6 can be connected on the connecting angle plate 14. At this time, in order to avoid the heat generated by the two ends of the heating source 3 passing out of the two installation vertical plates 13 rising vertically to cause the local heat on the left and right sides of the heater shell 1 to be too high, a flow dividing plate 17 can be arranged on the connecting angle plate 14 above the heating source 3. The cross section of the flow dividing plate 17 is L-shaped structure, which extends to the front edge of the flow guide plate 6, passes through the flow guide plate 6 and extends into the heat dissipation cavity 7, thereby covering the end of the heating source 3, so that the heat generated by the end of the heating source 3 can be as much as possible to diffuse to the heat dissipation cavity 7. The heat diffused into the heat dissipation cavity 7 will flow upward in the form of convection, as much as possible to avoid the heat concentrated directly above the heater shell 1, change the convection direction of hot air, increase the heat dissipation area of the upper shell 1.1, and make the temperature distribution on the left and right sides of the heater shell 1 more uniform.
[0024] The arrangement and design of the entire baby radiation warming table inclined heating device can effectively disperse the heat in the heater shell 1, reduce the occurrence of local high temperature of the heater shell 1, avoid the medical staff from being scalded, and effectively improve the reliability and cost performance of the inclined heating device.
