Description

Technical Field

[0001] The utility model relates to the technical field of heating plates, in particular to a heat exchange enhanced heating plate. Background Art

[0002] In the existing heating plate technology, as the core component of various heating devices, heating apparatuses and industrial heat sources, the performance of the heating plate directly affects the overall thermal efficiency and cost-effectiveness. The traditional design often adopts that the outer surface of a heating sleeve is connected with a heating substrate, and a plurality of heat dissipation fins are arranged outside the heating substrate to increase the heat dissipation area. However, this design has significant limitations: First, the shape design of the heating substrate often fails to fully optimize the ratio of the perimeter to the area, resulting in an unsmooth heat conduction path, low heat exchange efficiency, and partial heat accumulation inside the substrate that cannot be effectively dissipated, thereby affecting the overall heating effect.

[0003] Secondly, the design of the heat dissipation fins often lacks pertinence and fails to be customized according to specific application scenarios and heating requirements. Fins with different shapes, sizes and arrangements have different effects on air flow, thereby affecting the convection and radiation effects of heat. Due to the lack of innovative design, it is difficult for various types of heaters to make significant progress in heating efficiency and performance, and the user experience is thus limited.

[0062] A heat exchange enhanced heating plate, comprising a heating sleeve 1;

[0063] The heating sleeve 1 is sleeved on an external heating element. At least one heating substrate 2 is connected to the outer surface of the heating sleeve 1. A plurality of heat dissipation fins 3 are symmetrically and equidistantly arranged on both sides of the heating substrate 2. The plurality of heat dissipation fins 3 on the same side are arranged in parallel, and a heat dissipation channel is formed between adjacent heat dissipation fins 3;

[0064] The heating sleeve 1 includes a first circular tube 11 and a second circular tube 12. The first circular tube 11 and the second circular tube 12 are both hollow circular tubes. The second circular tube 12 is sleeved on the outer surface of the first circular tube 11, and the first circular tube 11 and the second circular tube 12 are coaxially arranged;

[0065] The heating substrate 2 is formed by fitting a heating substrate Q curve cluster. The heating substrate Q curve cluster includes a plurality of heating substrate Q curves. Each heating substrate Q curve includes a left plate QL straight line, a substrate QC1 curve, a right plate QR straight line and a substrate QC2 curve that are sequentially connected end to end. The substrate QC2 curve coincides with the outer surface of the second circular tube 12;

[0066] Wherein, the midpoint of the substrate curve QC1 is defined as the plate line midpoint QC10, the midpoint of the substrate QC2 curve is defined as the plate line midpoint QC20, the connection line of the plate line midpoint QC10 and the plate line midpoint QC20 is defined as the heating Z straight line, and the left plate QL straight line and the right plate QR straight line are symmetrically arranged with respect to the heating Z straight line;

[0067] The heat dissipation fin 3 is formed by fitting a cluster of heat dissipation fin P curves. The cluster of heat dissipation fin P curves includes multiple heat dissipation fin P curves, and each heat dissipation fin P curve includes a PS straight line on the fin and a PX straight line under the fin;

[0068] Define the heat dissipation area of the heating substrate Q curve as S, and define the perimeter of the heating substrate Q curve as L, where 1 ≤ L / S ≤ 2;

[0069] Define the horizontal line perpendicular to the heating Z straight line as the heating M perpendicular line;

[0070] When the PS straight line on the fin and the PX straight line under the fin are not symmetrically arranged with respect to the heating M perpendicular line, define the angle between the PS straight line on the fin and the heating M perpendicular line as θ, and define the angle between the PX straight line under the fin and the heating M perpendicular line as φ, where 30° ≤ θ < φ ≤ 70°, and 10° ≤ φ - θ ≤ 30°;

[0071] When the PS straight line on the fin and the PX straight line under the fin are symmetrically arranged with respect to the heating M perpendicular line, define the angles between the PS straight line on the fin and the PX straight line under the fin and the heating M perpendicular line as α, where 5° ≤ α ≤ 20°.

[0072] As Figure 1-8 shown, the working principle of this enhanced heat transfer heating plate is mainly based on the combined effects of heat conduction, convection, and radiation, and improves the heat transfer efficiency by optimizing the structural design. The specific working principle is as follows:

[0073] First, when an external heating element such as an electric wire or a heating tube is energized to generate heat, this heat is first transferred by direct contact to the outer heating sleeve 1.

[0074] Then, the heating sleeve 1 quickly conducts the received heat to the connected heating substrate 2. The heating substrate 2, as an intermediary for heat transfer, is designed to ensure good heat conduction performance to quickly and evenly disperse the heat from the heating sleeve 1.

[0075] Finally, multiple heat dissipation fins 3 are equidistantly arranged on both sides of the heating substrate 2, and their unique layout promotes air convection. The heat dissipation channels formed between adjacent heat dissipation fins 3 allow air to flow freely and take away heat. When combined with external devices such as fans, natural convection or forced convection is formed.

[0076] It should be noted that the heating substrate Q curve and the heat dissipation fin P curve are actually the horizontal sectional contour lines along the length direction of the heating plate.

[0077] Among them, by controlling the ratio of the perimeter L to the heat dissipation area S of the heat generation substrate Q curve in the heat generation substrate 2, that is, 1 ≤ L / S ≤ 2, while ensuring a sufficient heat dissipation area, the compactness of the structure and the heat conduction efficiency can be optimized. A smaller ratio helps reduce material usage and lower costs, while an appropriate ratio can ensure uniform heat distribution and avoid local overheating.

[0078] Most importantly, by optimizing the angle design between the PS straight line on the fin and the PX straight line under the fin of the heat dissipation fin 3 and the heat generation M perpendicular line respectively, it is the key to solve the problem that the shape of the heat dissipation fin 3 in the existing heating plate is not targeted and improve the heating effect of the heater. When the PS straight line on the fin and the PX straight line under the fin are symmetrically arranged with respect to the heat generation M perpendicular line, the heat dissipation fin 3 with this setting is called a straight fin, which is suitable for a radiation-type heating plate. The heater applying the straight fin can make the radiation heat transfer intensity greater than natural convection. When the PS straight line on the fin and the PX straight line under the fin are not symmetrically arranged with respect to the heat generation M perpendicular line, the heat dissipation fin 3 with this setting is called a bionic fishbone fin, which is suitable for a natural convection-type heater. The heater applying the bionic fishbone fin can make the natural convection heat transfer effect strong. Therefore, these angle designs can significantly improve the heating effects of different types of heaters in different shapes of the heat dissipation fin 3, meeting the different needs of customers.

[0079] Therefore, the beneficial effects of the present utility model are as follows:

[0080] 1. Improve heat transfer efficiency: Through the reasonable design of the cross-sectional ratio of the heat generation substrate 2 and the layout and angle design of the heat dissipation fin 3, the heat transfer efficiency of the heating plate is significantly improved. While the heat can be dissipated to the surrounding environment faster and more evenly, the compactness of the structure can be maintained, which is convenient for installation and use, and is especially suitable for occasions with limited space.

[0081] 2. Prolong service life: The effective heat dissipation design reduces the working temperature of the heating element and the heat generation substrate 2, reduces material aging and performance degradation caused by high temperature, and thus prolongs the service life of the product.

[0082] 3. Energy conservation and environmental protection: The high-efficiency heat transfer performance means that under the premise of achieving the same heating effect, energy consumption can be reduced, operating costs can be lowered, and the impact on the environment can be reduced.

[0083] 4. Wide application: This enhanced heat transfer type heating plate can be widely applied to fields such as household appliances, industrial heating, and automotive warm air systems, meeting the heating requirements in different scenarios.

[0084] In summary, the present utility model is a heat - enhanced heating plate that can significantly improve heat exchange efficiency, reduce material costs, and meet diverse heating requirements. This new - type heating plate will achieve more efficient, more economical, and more flexible heat transfer and dissipation by optimizing the geometric shape of the heating substrate 2, improving the design and layout of the heat - dissipating fins 3, etc., thereby promoting the innovative development in the fields of heating equipment and heating technology.

[0085] For further illustration, the distance X between the left - plate QL straight line and the right - plate QR straight line gradually decreases from one end of the substrate QC2 curve to one end of the substrate QC1 curve.

[0086] As Figure 1 and 5 shown, specifically, the distance X between the left - plate QL straight line and the right - plate QR straight line, which is the width of the heating substrate 2, shows a gradually decreasing trend in the length direction of the substrate. This design is smoothly connected and controlled by two curves, QC1 and QC2, for this gradual change process. This gradually - changing structure enables the heat on the heating plate to be guided to a certain extent during the conduction process, allowing the heat to be more evenly distributed across the entire substrate rather than accumulating excessively in a certain area. It helps to form a more uniform heat - flow distribution inside the substrate, reducing heat - stress concentration and the risk of performance degradation or damage caused by local overheating.

[0087] For further illustration, two of the heating substrates 2 are connected to the outer surface of the heating sleeve 1. Define the two heating substrates 2 as the upper - heating substrate 21 and the lower - heating substrate 22 respectively, and the heating Z straight line in the upper - heating substrate 21 and the heating Z straight line in the lower - heating substrate 22 are collinearly arranged;

[0088] Define the length of the heating Z straight line in the upper - heating substrate 21 as Ls, and define the length of the heating Z straight line in the lower - heating substrate 22 as Lx;

[0089] Among them, 1 ≤ Ls / Lx ≤ 2.

[0090] As Figure 1 and Figure 5 shown, specifically, through two heating substrates 2 - - the upper - heating substrate 21 and the lower - heating substrate 22, effective heating and heat exchange of a specific area or fluid on the heating sleeve 1 are achieved. The heating sleeve 1 is internally embedded with heating elements such as electric heating wires and electric heating films, which generate heat after being energized. The upper - heating substrate 21 and the lower - heating substrate 22 are respectively located on the upper and lower sides of the outer surface of the heating sleeve 1, and the heating Z straight lines in both of them can be understood as the main heating areas or directions of the heating elements being collinearly arranged, which means that the heat - output directions of both are the same, helping to form a stable thermal field.

[0091] By adjusting the length ratio of the upper heating substrate 21 and the lower heating substrate 22, within the range of 1 ≤ Ls / Lx ≤ 2, the heat generation amount and temperature distribution of the two substrates can be precisely controlled. Specifically, the shorter lower heating substrate 22 can reach a higher surface temperature faster, thereby forming a larger temperature difference between its surface and the surrounding fluid, enhancing the natural convection effect, increasing the inlet flow rate of the fluid, and further enhancing the heat transfer efficiency. The longer upper heating substrate 21 can provide a stable heat output and maintain the thermal balance of the entire system without excessively increasing the temperature and causing structural deformation.

[0092] For further illustration, define the angle between the left plate QL line and the right plate QR line in the upper heating substrate 21 as βs, and define the angle between the left plate QL line and the right plate QR line in the lower heating substrate 22 as βx;

[0093] Among them, 0° ≤ βs or βx ≤ 5°.

[0094] As Figure 1 and Figure 5 shown, specifically, although only the angle between the left plate QL line and the right plate QR line is restricted within a very small range, compared with the rectangular heating substrate in the prior art, this design can significantly reduce the material amount required for the heating substrate 2, thereby reducing the production cost.

[0095] It should be noted that although the material usage is reduced, due to proper angle control, the strength of the structure of the heating substrate 2 is not affected, and it can maintain good stability and durability.

[0096] For further illustration, when the PS line on the fin and the PX line under the fin are not symmetrically arranged with respect to the heating M perpendicular line, the P curve of the heat dissipation fin further includes a first P1P2 curve, a second P3P4 curve, and a third P5P6 curve;

[0097] The two ends of the first P1P2 curve are the end point P1 and the end point P2 respectively, the two ends of the PX line under the fin are the end point P2 and the end point P3 respectively, the two ends of the second P3P4 curve are the end point P3 and the end point P4 respectively, the two ends of the PS line on the fin are the end point P4 and the end point P5 respectively, and the two ends of the third P5P6 curve are the end point P5 and the end point P6 respectively;

[0098] Among them, the end point P1 coincides with the end point P6 of the P curve of the heat dissipation fin 3 that is adjacent to and close to the heating sleeve 1; the end point P6 coincides with the end point P1 of the P curve of the heat dissipation fin 3 that is adjacent to and far from the heating sleeve 1, and both the end point P1 and the end point P6 coincide with the left plate QL line or the right plate QR line;

[0099] The first P1P2 curve is tangent to the lower fin PX straight line at the end point P2, the second P3P4 curve is tangent to the lower fin PX straight line at the end point P3, the second P3P4 curve is tangent to the upper fin PS straight line at the end point P4, and the third P5P6 curve is tangent to the upper fin PS straight line at the end point P5.

[0100] Furthermore, it is defined that the extension line of the upper fin PS straight line in one of the heat dissipation fins 3 intersects the heating Z straight line at the intersection point P0, and the extension line of the upper fin PS straight line in the heat dissipation fin 3 adjacent to one of the heat dissipation fins 3 intersects the heating Z straight line at the intersection point P0';

[0101] The connection line between the intersection point P0 and the intersection point P0' is defined as the straight line P0P0', and the length of the straight line P0P0' is defined as H1;

[0102] The connection line between the intersection point P0 and the end point P2 is defined as the straight line P0P2, the straight line P0P2 is perpendicularly arranged with respect to the straight line P0P0', and the length of the straight line P0P2 is defined as L1;

[0103] The arc radius of the first P1P2 curve is defined as R1, the arc radius of the second P3P4 curve is defined as R2, and the arc radius of the third P5P6 curve is defined as R3.

[0104] Among them, 2L1 ≤ H1 ≤ 5L1, R1 ≤ 0.5L1, R2 ≤ 0.5L1, and R3 ≤ 0.5L1.

[0105] As Figure 1-4 shown, through the above design, a strengthened heat transfer type heating plate with bionic fishbone-shaped heat dissipation fins 3 can be obtained, which is applicable to a natural convection type heater.
