[0002] With the recent development of indoor heaters (bathroom heaters), there is an increasing application of far-infrared light wave tube heating and PTC heating sheets. The basic structure of a traditional far-infrared heating tube is a built-in reflective cover that reflects heat into the heating space in the form of light waves.

The traditional PTC heating sheet structure uses a fan to force heat into the indoor space, and the thermal efficiency of the heating sheet is relatively low. Based on the above, this application provides a composite light wave tube heater that fully utilizes the advantages of both. Utility Model Content

DETAILED DESCRIPTION

[0034] The present invention will be described in further detail below with reference to the accompanying drawings. Example

[0035] Reference Figure 1 , is a heater disclosed in the utility model, comprising: a heating element 1, the heating element 1 having an electrode portion 101, the heating element 1 generates heat when the electrode portion 101 is energized; a heat-conducting slot 2, the heat-conducting slot 2 surrounds the heating element 1 on three sides and is attached to the heating element 1, the heat-conducting slot 2 is provided with a radiation surface 201; a heat dissipation component 3, the heat dissipation component 3 is fixed to the outer side of the heat-conducting slot 2; an air guide portion 202 is provided on one side of the heat-conducting slot 2, the air guide portion 202 and the heating element 1 enclose an air guide groove 203, and the air guide groove 203 penetrates axially along the heat-conducting slot 2; wherein the heating element 1 is a heating tube or other heating object with low power and high radiation heat, and the cross-section of the heating element 1 is circular, which can better dissipate heat in a radiation manner.

[0036] In this embodiment, the heating element 1 is fixed in the heat-conducting card slot 2, and the heating element 1 is tightly fitted with the two inner sides of the heat-conducting card slot 2, and the heat dissipation component 3 is fixed to the outer side of the heat-conducting card slot 2 to dissipate heat; the heating element 1 has an electrode part. When the electrode part 101 is in the power-on state, the heating element 1 starts to work and generates heat, and part of the heat generated by the heating element 1 during operation is transferred to the heat dissipation component 3 through the heat-conducting card slot 2 to dissipate the heat; the other part of the heat is radiated to the air in the area through the radiation surface 201 and the air guide groove 203 to convert the surrounding air into hot air, so as to achieve the effect of heating the ambient air, so that the heater can provide heat in the form of wind heating or radiation heating; the air guide groove 203 provided therein has the function of guiding air, which can further accelerate the dissipation of the radiated heat to the air in the area, so that the heating effect is better.

[0037] Among them, the electrode part 101 includes two electrodes, the heating element 1 includes a sleeve and a heating body inserted into the sleeve, the heating body is connected between the two electrodes, and the two electrodes extend from the two ends of the sleeve respectively and protrude from the end of the thermal conductive card slot 2; insulating seals 113 are also sleeved at both ends of the sleeve, and the electrodes pass through the insulating seals 113 to prevent leakage.

[0038] The heating body may be a heating wire.

[0039] In this embodiment, the heat-conducting slot 2 is U-shaped, the heating element 1 fits tightly against the two inner side surfaces of the heat-conducting slot 2, and an air guide portion 202 is provided at the bottom. The air guide groove 203 formed by the air guide portion 202 and the heating element 1 is triangular. Similarly, the air guide groove 203 can also be semicircular, rectangular, or other shapes that are conducive to the passage of wind or airflow.

[0040] In order to facilitate heat conduction, a heat-conducting material is filled between the heating element 1 and the heat-conducting slot 2 , and the heat-conducting material can be a heat-conducting glue.

[0041] Specifically, such as Figure 3 As shown, in this embodiment, the heating element 1 is fixed in the thermal conductive slot 2, and the two are bound as a group for emitting and conducting heat, which can be 1 group or more; the heat dissipation component 3 is fixed to the outer side of the thermal conductive slot 2, so the heat dissipation component 3 is connected between the two groups of thermal conductive slots 2 fixed with the heating element 1, and the outer side of the outermost thermal conductive slot 2 in the multiple groups of thermal conductive slots 2 fixed with the heating element 1 is also connected to the heat dissipation component 3. The heat dissipation component 3 set on the outermost side is responsible for the heat generated by the heating element 1 in the outermost thermal conductive slot 2 to ensure that this part of the heat can also be effectively dissipated. The number of heating elements 1, thermal conductive slots 2 and heat dissipation components 3 can be determined according to the needs of the specific electrical device, wherein the minimum unit is 1 group of heating elements 1 and thermal conductive slots 2 matched with two heat dissipation components 3. In this way, in actual use, heaters of corresponding specifications and sizes can be used according to actual use requirements.

[0042] like Figure 1 As shown, the heat dissipation assembly 3 includes a first support plate 301, a second support plate 303 and a wavy heat sink 302. The first support plate 301 and the second support plate 303 enclose a heat dissipation space. The heat dissipation space is rectangular. The wavy heat sink 302 is placed in the heat dissipation space and is respectively connected to the first support plate 301 and the second support plate 303. The first support plate 301 is connected to the heat conductive card slot 2; wherein the first support plate 301 and the second support plate 303 are both made of heat conductive materials and have good thermal conductivity.

[0043] That is, the first support plate 301 is connected to the outer side of the heat-conducting card slot 2, and the first support plate 301 and the second support plate 303 enclose a heat dissipation space. Therefore, a portion of the heat generated by the heating element 1 during operation can be transferred to the wavy heat sink 302 in the heat-conducting card slot 2 through the first support plate 301. The heat at the wavy heat sink 302 can heat the air in the area to form hot air. When the surrounding air flows toward the heater, the air flows through the wavy heat sink 302 in the heat dissipation space, which can blow the hot air in the area where the heat dissipation space is located to the desired area, such as a bathroom, room, etc., and at the same time heat the newly arrived air to form new hot air for circulation, thereby achieving the effect of uniformly and quickly raising the temperature of the desired area.

[0044] This enables the electrical device equipped with the heater to have both the function of radiation heating and the function of wind heating, greatly improving the performance of the product.

[0045] In addition, the cross-sectional shapes of the first support plate 301 and the second support plate 303 can be a rectangle with an opening, a straight line, or two L-shapes; the first support plate 301 and the second support plate 303 enclose a heat dissipation space, and the wavy heat sink 302 is fixed in the heat dissipation space, and the two side edges are respectively connected to the first support plate 301 and the second support plate.

[0046] Specifically, the distance between two adjacent wave crests of the wave-shaped heat sink 302 is 2-5 mm.

[0047] In this embodiment, if Figure 5 As shown, the wavy heat sink 302 is provided with a window structure 4. The window structure 4 includes a plurality of leaf windows 401 provided on the wavy heat sink 302. The leaf windows 401 are long strips, and a blade 402 is connected to the side of each leaf window 401. The end cross-section of the blade 402 is fan-shaped. One side of the long side of the blade 402 is connected to the side of the leaf window 401, while the other side of the long side of the blade 402 forms an opening with the other side of the leaf window 401. The length of the blade 402 is shorter than the length of the leaf window 401. At the same time, a closed cover 403 is provided at both ends of the blade 402, and the other side of the closed cover 403 is connected to the corresponding end of the leaf window 401.

[0048] The front, side and top surfaces of the enclosing cover 403 are all fan-shaped. The outward angle of the blades 402 is 28-32 degrees, which makes it easier for air to enter and improves the heat transfer effect.

[0049] There are two groups of blades 401 on each side of the wavy heat sink 302 , and each group has four blades. The two groups of blades 401 are symmetrically arranged on the surface of the wavy heat sink 302 .

[0050] When the wavy heat sink 302 of this embodiment is in use, a closed cover 403 is provided on both sides of the blade 401 so that the end of the blade 402 is connected to the leaf window 401. In addition, the blade 402 is designed to have a fan-shaped end face. When in use, the amount of air escape can be effectively reduced, the time the air stays in the blade 401 is increased, and the contact area between the air and the wavy heat sink 302 is increased, thereby effectively improving the heat transfer efficiency and improving the heating effect on the air. Example

[0051] Reference Figure 4In this embodiment, the difference is that the heat dissipation component 3 includes a plurality of fins 311 arranged at intervals, each fin 311 is connected to the outer side of the heat conduction card slot 2, and the fin 311 and the heat conduction card slot 2 are integrally formed.

[0052] In this embodiment, a plurality of fins 311 are arranged at intervals, and the fins 311 are integrally formed with the heat conductive slot 2. On the one hand, this design is more conducive to the heating element 1 to conduct heat to the fins 311, so as to improve the heat conduction efficiency; on the other hand, the fins arranged at intervals are conducive to the dissipation of heat, and are more conducive to dissipating the heat generated by the heater to the area where it is located.

[0053] At the same time, this arrangement further shortens the distance between the heating element 1 and the heat dissipation assembly 3, allowing a portion of the heat generated by the heating element 1 to be quickly transferred through the heat conduction slot 2 to the heat dissipation assembly 3, namely the fins 311, thereby effectively improving the efficiency of heat conduction and reducing energy loss. Furthermore, this arrangement also reduces the overall volume by reducing the distance between the heating element 1 and the fins 311, thereby reducing the volume of the electrical device.

[0054] The fins 311 are arranged at an angle of 30 to 60 degrees to the outer side surface of the heat conducting slot 2 .

[0055] The distance between any two adjacent fins 311 is 2 to 5 mm.

[0056] In addition, if Figure 5 As shown, in this embodiment, the fin 311 is provided with a window structure 4. The window structure 4 includes a plurality of leaf windows 401 provided on the fin 311. The leaf windows 401 are in the shape of long strips. A blade 402 is connected to the side of each leaf window 401. The end section of the blade 402 is fan-shaped. One side of the long side of the blade 402 is connected to the side of the leaf window 401, while the other side of the long side of the blade 402 forms an opening with the other side of the leaf window 401. The length of the blade 402 is shorter than the length of the leaf window 401. At the same time, a sealing cover 403 is provided at both ends of the blade 402, and the other side of the sealing cover 403 is connected to the corresponding end of the leaf window 401.

[0057] The front, side and top surfaces of the enclosing cover 403 are all fan-shaped. The outward angle of the blades 402 is 28-32 degrees, which makes it easier for air to enter and improves the heat transfer effect.

[0058] There are two groups of blade windows 401 on each side of the fin 311 , and each group has four blade windows. The two groups of blade windows 401 are symmetrically arranged on the surface of the fin 311 .

[0059] When the fin 311 of this embodiment is in use, a closed cover 403 is set on both sides of the blade 401 to connect the end of the blade 402 to the leaf window 401. In addition, the blade 402 is designed to have a fan-shaped end face. When in use, the amount of air escape can be effectively reduced, the time the air stays in the blade 401 is increased, and the contact area between the air and the fin 311 is increased, thereby effectively improving the heat transfer efficiency and improving the heating effect on the air. Example

[0060] Reference Figure 6 In this embodiment, the difference is that the ends of the thermal conductive slots 2 are connected to form a circular ring or an elliptical ring with a notch, and the heating element 1 is fixed in the thermal conductive slots 2 and its shape matches it. The two electrodes of the electrode part 101 extend from the notch of the thermal conductive slots 2. Of course, the heat dissipation component 3 matched therewith is also a circular ring that matches the thermal conductive slots 2, and the heat dissipation component 3 of the outer ring is larger than the heat dissipation component 3 of the inner ring.

[0061] In this embodiment, the whole is in the shape of a circular ring or an elliptical ring with a notch. When air flows into the heater, the heating of the air is more concentrated, and the air can stay longer, thereby improving the heat conduction efficiency, thereby being able to heat the air in the area faster, that is, heating faster.
