Description

Technical Field

[0001] The present invention belongs to the technical field of heating equipment, and more specifically, relates to a controllable temperature thermal power generation device and heating equipment. Background Art

[0002] Heating equipment is widely used outdoors, at home and in some heating scenarios. However, heating equipment often has the problem of slow temperature rise in the surrounding environment due to natural heat dissipation. Therefore, cooling fans are generally used to speed up the circulation of hot air, thereby achieving the purpose of rapid temperature rise in the environment.

[0003] Thermoelectric fans do not require additional power, are convenient and can effectively reduce energy consumption. Therefore, they are very popular among consumers. Thermoelectric power generation is based on the Seebeck effect. When there is a temperature difference between the high-temperature heat source of the furnace and the surrounding low-temperature environment, the thermoelectric material generates voltage to drive the fan to rotate. The rotation of the fan accelerates the air flow, quickly takes away heat, and improves the heat dissipation efficiency. However, the maximum temperature tolerance of this type of thermoelectric heat generator that can be used to power thermoelectric fans is limited. If the temperature exceeds its limit, it will fail. At the same time, excessive temperature will also affect the service life of the motor and the line.

[0004] Currently, the thermoelectric fan device is placed directly above the furnace body in the market. This method can easily cause the temperature of the thermoelectric plate to be too high, making it difficult to control the temperature of the thermoelectric plate.

[0024] See also Figure 1 , Figure 2 , Figure 6 as well as Figure 7 Now, a controllable temperature thermal power generation device provided by the present invention is described. A controllable temperature thermal power generation device includes a support seat 300, a temperature difference fan assembly and a heat insulation and heat absorption assembly.

[0025] The support base 300 is used to be arranged above the furnace body, and a temperature difference heating electric sheet 400 is arranged on the top of the support base 300; the temperature difference fan assembly includes a fan support 100, a temperature difference power generation fan 200 and a drive motor 210, the fan support 100 is installed on the top of the support base 300 and is located above the temperature difference heating electric sheet 400, the drive motor 210 is arranged on the fan support 100 and is electrically connected to the temperature difference heating electric sheet 400, and the temperature difference power generation fan 200 is connected to the driving end of the drive motor 210; the heat insulation and heat absorption assembly includes a fan support 100 for being arranged on the furnace body The upper insulating heat absorbing plate 500, the lower end surface of the insulating heat absorbing plate 500 forms a heating surface, the upper end surface of the insulating heat absorbing plate 500 has a heat transfer area 510 and a heat dissipation area 520, the heat dissipation area 520 is arranged around the outer periphery of the heat transfer area 510, and the support seat 300 is installed on the heat transfer area 510; the insulating heat absorbing plate 500 blocks the heat of the furnace body from directly acting on the temperature difference heating electrode 400, the insulating heat absorbing plate 500 absorbs the heat of the furnace body and conducts it to the temperature difference heating electrode 400 through the heat transfer area 510 and the support seat 300, and dissipates heat to the outside through the heat dissipation area 520.

[0026] The present invention provides a controllable temperature heat power generation device. Compared with the prior art, the support seat 300, the temperature difference heating electric sheet 400 and the fan support 100 are installed in sequence from bottom to top. The temperature difference power generation fan 200 is installed on the fan support 100 through the driving motor 210, and the heat insulation heat absorption plate 500 is arranged below the support seat 300 and above the furnace body. The heat insulation heat absorption plate 500 blocks the heat of the furnace body from directly acting on the temperature difference heating electric sheet 400 to protect the temperature difference heating electric sheet 400 from being damaged by high temperature. At the same time, the heating surface of the heat insulation heat absorption plate 500 absorbs the heat of the furnace body, and part of the heat absorbed by the heat insulation heat absorption plate 500 is sequentially conducted to the temperature difference heating electric sheet 400 through the heat transfer area 510 and the support seat 300, so that it generates a temperature difference with the external environment to provide electric energy for the driving motor 210. In addition, another part of the heat absorbed by the heat insulation heat absorption plate 500 is dissipated to the outside through the heat dissipation area 520. When the sum of the heat conducted by the insulating heat absorbing plate 500 to the support seat 300 and the heat dissipated by the insulating heat absorbing plate 500 itself is equal to or close to the heat absorbed by the heating surface of the insulating heat absorbing plate 500, a dynamic temperature balance can be achieved, and the temperature of the support frame no longer increases, but fluctuates within a very small temperature range, thereby achieving the purpose of temperature control.

[0027] See also Figure 3 and Figure 8 The material of the heat insulating and absorbing plate 500 is a metal single substance or alloy of zinc, aluminum or copper, and the thermal conductivity of the heat insulating and absorbing plate 500 is in the range of 90W / (m×k) to 300W / (m×k). The lower end surface of the heat insulating and absorbing plate 500 is provided with a heat absorbing coating 530, wherein the heat absorbing coating 530 is made of a wave absorbing and heat increasing coating by brushing or spraying, and the wave absorbing and heat increasing coating is a commercially available product, which is mainly used to absorb infrared waves to promote heat absorption and improve its heat utilization efficiency.

[0028] See also Figure 5 and Fig. 9 The support base 300 is a metal frame structure, and the middle part of the support base 300 is provided with at least one heat transfer cavity 310. When heat is conducted through the heat transfer cavity 310, the heat conductivity of the air inside the heat transfer cavity 310 is lower than that of the metal frame compared to metal. The heat transfer cavity 310 can reduce the heat conducted from the heat insulation and heat absorption plate 500 to the temperature difference heating electric sheet 400 through the support base 300, and further protect the temperature difference heating electric sheet 400 from being damaged by high temperature. The number and size of the heat transfer cavity 310 are adjusted according to the amount of heat absorbed by the heat insulation and heat absorption plate 500.

[0029] The upper end surface of the support base 300 is provided with a mounting surface 320 for mounting the thermoelectric chip 400. The mounting surface 320 is a planar structure. The lower end surface of the fan support 100 is also a planar structure. The thermoelectric chip 400 is pressed between the two planes, and thermal conductive glue is applied to the upper and lower end surfaces of the thermoelectric chip 400 to keep the thermoelectric chip 400 stable. In addition, a mounting groove can also be provided on the upper end surface of the support base 300. The mounting surface 320 is located at the bottom of the mounting groove. Both ends of the mounting groove are connected. The width of both sides of the mounting groove is slightly larger than the width of the thermoelectric chip 400. Specifically, the width of both sides of the mounting groove is 3-5 mm larger than the width of the thermoelectric chip 400. The thermoelectric chip 400 is adapted to be placed in the mounting groove and is located in the middle of the mounting surface 320. When the thermoelectric sheet 400 is not heated, there is an installation gap of 1.5-2.5mm on both sides of the width direction of the thermoelectric sheet 400 and the two sides of the installation groove. As the temperature of the thermoelectric sheet 400 continues to rise, the thermoelectric sheet 400 will expand due to the heat. The installation gaps reserved on both sides of the thermoelectric sheet 400 can provide deformation space for its expansion, thereby preventing the thermoelectric sheet 400 from working in a squeeze environment for a long time and ensuring its service life.

[0030] See also Figure 5 , the lower end surface of the bottom plate of the support seat 300 is a plane, which is completely attached to the heat transfer area 510 of the heat insulation and heat absorption plate 500. At this time, the heat transfer cavity 310 is one and is located in the middle of the upper end surface of the bottom plate, and the width of the heat transfer cavity 310 is less than half the length of the bottom plate. When conducting heat upward, the bottom plate of the support seat 300 can completely absorb the heat of the heat transfer area 510, and the absorbed heat is relatively high. The width of the heat transfer cavity 310 is relatively small relative to the length of the bottom plate. One heat transfer cavity 310 cooperates to form the side walls on both sides of the heat transfer cavity 310 and conducts heat at the same time. When conducting heat, the two sides of the upper end surface of the bottom plate can also form a heat dissipation surface, which can dissipate heat to the outside. In other words, when the bottom plate of the support seat 300 absorbs more heat, the heat conducted to the temperature difference heating electrode 400 can be reduced by setting a heat transfer cavity 310 in the middle of the upper end surface of the bottom plate.

[0031] See also Fig. 9, when the lower end surface of the bottom plate of the support seat 300 is provided with a plurality of contact edges, the plurality of contact edges are simultaneously and completely attached to the heat transfer area 510 of the heat insulating and absorbing plate 500. At this time, the heat transfer cavities 310 are multiple and connected side by side, and the plurality of heat transfer cavities 310 are distributed over the upper end surface of the bottom plate. When conducting heat upward, the bottom plate of the support seat 300 can only partially absorb the heat of the heat transfer area 510 through contact, and the amount of heat absorbed is relatively low. The heat transfer cavities 310 are completely distributed over the length direction of the bottom plate, and the plurality of heat transfer cavities 310 cooperate to form the side walls on both sides of each heat transfer cavity 310 to conduct heat at the same time. In other words, when the bottom plate of the support seat 300 absorbs less heat, the amount of heat conducted to the temperature difference heating electrode 400 can be increased by distributing a plurality of heat transfer cavities 310 over the upper end surface of the bottom plate.

[0032] See also Fig.10 The fan support 100 has a plurality of heat dissipation chambers 110, one of which is located in the middle of the fan support, and the other heat dissipation chambers 110 are symmetrically distributed on the left and right sides of the middle heat dissipation chamber 110, including two outer heat dissipation chambers and two oblique upper heat dissipation chambers 110, and the top of the two oblique upper heat dissipation chambers 110 has a top heat dissipation chamber 110. A middle heat dissipation chamber 110, two outer heat dissipation chambers 110, two oblique upper heat dissipation chambers 110 and a top heat dissipation chamber 110 together constitute a fan support 100 with a panda pattern, which can improve the aesthetics. The plurality of heat dissipation chambers 110 can conduct the heat of the fan support to the outside, reduce the influence of the temperature of the fan support itself on the drive motor 210 and the temperature difference power generation fan 200, and ensure the service life of the drive motor 210 and the temperature difference power generation fan.

[0033] The fan support 100 has a card slot 120 disposed on the opposite sides of the heat dissipation cavity 110 in the middle thereof. A plug-in board 220 is inserted along the two card slots 120. The part constituting the card slot has a certain elasticity. When the plug-in board 220 is inserted into the card slot 120, a certain clamping force can be formed by the rebound of the card slot 120 to ensure the stability of the installation. The drive motor 210 is installed on one side of the plug-in board 220 and extends to the outside of the fan support 100. The temperature difference power generation fan 200 is located on the outside of the drive motor 210 away from the fan bracket. The drive motor 210 and the temperature difference power generation fan 200 are both located on one side of the fan support 100, which can reduce the influence of high temperature on them.

[0034] See also Figure 2 and Figure 4, the heat-insulating heat-absorbing assembly also includes a temperature-control tray 600. The temperature-control tray 600 is used to be arranged above the furnace body, the heat-insulating heat-absorbing plate 500 is arranged on the upper end surface of the heat-insulating heat-absorbing plate 500, and the temperature-control tray 600 is provided with a plurality of heat-transmitting holes 610 in a matrix, and the plurality of heat-transmitting holes 610 are all located in the longitudinal projection area of ​​the heat-insulating heat-absorbing plate 500, and a mounting portion is provided on one side of the temperature-control tray 600. Part of the heat of the furnace body is blocked and weakened by the temperature-control tray 600, and the other part of the heat directly acts on the heat-insulating heat-absorbing plate 500 through the plurality of heat-transmitting holes 610 arranged in a matrix. While ensuring that the heat-insulating heat-absorbing plate 500 can absorb heat, the problem of damage to the thermoelectric power generation sheet due to excessive heat will not occur.

[0035] Preferably, the multiple heat-transmitting holes 610 may be in a circular, oval, square, polygonal, or irregular shape. The total heat-transmitting area of ​​the multiple heat-transmitting holes 610 accounts for 10% to 50% of the cross-sectional area of ​​the temperature-controlled tray 600. The ratio of the total heat-transmitting area of ​​the multiple heat-transmitting holes 610 to the cross-sectional area of ​​the tray body is adjusted according to the heat of the furnace body.

[0036] The temperature control tray 600 is made of stainless steel, preferably 316 stainless steel, which can effectively conduct heat to the temperature difference heating electrode 400 while blocking direct baking by the open flame of the furnace.

[0037] The temperature control tray 600 is provided with a plurality of side edges 620 extending vertically upwards in the circumference direction. The plurality of side edges 620 are connected end to end and are arranged around the outer circumference of the heat insulating and absorbing plate 500, so that the temperature control tray 600 forms a box structure with an opening upwards, so as to ensure that the heat insulating and absorbing plate 500 placed on the upper end surface of the temperature control tray 600 remains stable. The mounting portion is arranged on any side edge 620 and extends outwards. The mounting portion is integrally formed with the side edge 620, and both the side edge 620 and the mounting portion are formed by stamping and bending. The upper end of each side edge 620 is provided with a claw 630 bent inwardly, and a clamping gap is formed between the claw 630 and the temperature control tray 600. The edge of the insulation heat absorbing plate 500 is clamped in the clamping gap, which can limit the insulation heat absorbing plate 500 installed on the upper end surface of the temperature control tray 600 from moving upward. At the same time, the insulation heat absorbing plate 500 is limited by the side edge 620 to ensure that it will not move in any horizontal direction. Finally, the insulation heat absorbing plate 500 is stably installed on the upper end surface of the temperature control tray 600.

[0038] Specifically, the mounting portion includes a mounting plate 640 and two connecting plates 650. The mounting plate 640 is disposed on one side of the temperature control tray 600, and the mounting plate 640 is integrally formed on the side edge 620 of one side of the temperature control tray 600. Two connecting plates 650 are respectively disposed on both sides of the mounting plate 640 and extend upward, and the connecting plates 650 are also integrally formed on both sides of the mounting plate 640. A positioning notch 651 is disposed at the upper end of the connecting plate 650, and the positioning notch 651 is an L-shaped notch, and the opening of the L-shaped notch is located at the top thereof. The connecting plate 650 is clamped on the upper part of the protective net of the furnace body by means of the positioning notch 651 to support the mounting plate 640 in a horizontal state.

[0039] When installing the temperature-controlled tray 600, insert the mounting plate 640 from the lower part of the beam 710 on the upper part of the protective net, move the temperature-controlled tray 600 upward, insert the transverse pull rod from the opening of the L-shaped slot, and then move the temperature-controlled tray 600 laterally to cooperate with the beam 710 through the positioning slot 651 to complete the installation of the temperature-controlled tray 600 and the protective net.

[0040] Preferably, a relief limit groove 641 is provided in the middle of the mounting plate 640 on the side away from the temperature control tray 600, the opening direction of the relief limit groove 641 is away from the temperature control tray 600, and the longitudinal beam 720 on the upper part of the protection net is inserted into the interior through the opening of the relief limit groove 641. The groove bottom of the relief limit groove 641 abuts against the longitudinal beam 720, and cooperates with the limiting structure of the positioning notches 651 on both sides and the crossbeam 710 to support the mounting plate 640, so that the tray body is in a horizontal state.

[0041] Based on the same inventive concept, the present invention also provides a heating device, which uses the above-mentioned controllable temperature thermal power generation device and thus has the same beneficial effects as the above-mentioned controllable temperature thermal power generation device.

[0042] See also Figures 1 to 5 ,as well as Fig.10 When installing the controllable temperature heat generating device on the heating furnace with the guardrail 700, the fan support 100, the temperature difference heating sheet 400, the support seat 300, the heat insulation and heat absorption plate 500 and the temperature control tray 600 are installed from top to bottom in sequence, and the temperature difference power generating fan 200 is installed on the fan support 100 through the driving motor 210, and then the driving motor 210 and the temperature difference heating sheet 400 are electrically connected by wires. Finally, the avoidance limit groove 641 on the mounting plate 640 on one side of the temperature control tray 600 and the positioning notch 651 on the connecting plate 650 are used to install with the longitudinal beam 720 and the cross beam 710 on the upper part of the guardrail 700, respectively, so as to quickly complete the installation of the controllable temperature heat generating device on the heating furnace with the guardrail 700.

[0043] Among them, the temperature control tray 600 can form horizontal support for the fan support 100, the temperature difference heating plate 400, the support seat 300 and the heat insulation and heat absorption plate 500, while blocking the direct heat and indirect heat transfer of the furnace body, and finally achieving the purpose of controllable temperature of the thermal power generation device on the heating furnace.

An assembly block 330 is connected to one side of the support base 300, and an arc-shaped notch is formed on one side of the assembly block 330. The same side of the heat insulation and heat absorption plate 500 also has an arc-shaped notch of the same shape. The arc-shaped notches of the assembly block 330 and the heat insulation and heat absorption plate 500 are adapted to fit on the outer wall of the chimney 800 of the fireplace, and then the assembly block 330 is tied and fixed to the chimney 800 by a strap connected to the assembly block 330, so as to quickly complete the installation of the controllable temperature heat generating device on the fireplace.

[0045] Among them, the fan support 100, the support seat 300 and the insulating heat absorbing plate 500 are bolted in sequence, and the assembly block 330 cooperates with the binding strap to form a horizontal support for the fan support 100, the temperature difference heating electrode 400, the support seat 300 and the insulating heat absorbing plate 500, while blocking the direct heat and indirect heat transfer of the furnace body, and finally achieving the purpose of temperature control of the thermal power generation device on the fireplace.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
