Description

Technical Field

[0001] The embodiments of the present disclosure belong to the technical field of heating equipment, and specifically relate to a heat dissipation system and a heating equipment. Background Art

[0002] An oven is an electric heating appliance that uses radiant heat from electric heating elements to bake food. Most ovens use circuit boards to control the operation of each unit. If the heat dissipation of the circuit board is insufficient, the temperature of the circuit board will rise too high, thereby reducing the life of the circuit board.

[0003] In the related art, most ovens use fans to dissipate heat from the oven cavity. If the fan is always in working condition when the oven is powered on, that is, the fan is in working condition when the oven is not in cooking state, this will cause a certain amount of electricity waste. At the same time, the fan continues to rotate, and the noise of the fan will affect the user. If it is controlled by cooking time, that is, when the oven is in cooking state, the fan rotates, and when the oven is not in cooking state, the fan stops rotating. Then for a period of time after the oven switches from cooking state to non-cooking state, the temperature inside the oven is high. At this time, the fan stops rotating, which will cause the cavity to slowly cool down at a higher temperature, thereby affecting the service life of other components in the oven.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 , Figure 2 As shown, an embodiment of the present disclosure provides a heat dissipation system 100, which is applied to a heating device 1000. The heat dissipation system 100 includes a temperature difference power generation component 10 and a heat dissipation component 20. The temperature difference power generation component 10 has a hot end 101, a cold end 102 and a power generation output end; the hot end 101 and the cold end 102 of the temperature difference power generation component 10 are arranged at different positions of the heating device 1000, and the power generation output end of the temperature difference power generation component 10 is electrically connected to the power supply input end of the heat dissipation component 20; wherein, the temperature difference power generation component 10 can provide a working voltage to the heat dissipation component 20 when the temperature difference between the hot end 101 and the cold end 102 reaches a temperature difference threshold, so as to drive the heat dissipation component 20 to work.

[0034] The heat dissipation system of the embodiment of the present disclosure includes a thermoelectric power generation component 10 and a heat dissipation component 20, wherein the cold end 102 and the hot end 101 of the thermoelectric power generation component 10 are respectively arranged at different positions of the heating device 1000, and the thermoelectric power generation component 10 senses the temperature difference at different positions of the heating device 1000 through the cold end 102 and the hot end 101. When the temperature difference between the cold end 102 and the hot end 101 of the thermoelectric power generation component 10 reaches a temperature difference threshold, the thermoelectric power generation component 10 provides the working voltage required by the heat dissipation component 20 to the power supply input end of the heat dissipation component 20 through the power generation output end, thereby driving the heat dissipation component 20 to work. When the temperature difference between the cold end 102 and the hot end 101 of the thermoelectric power generation component 10 does not reach the temperature difference threshold, the thermoelectric power generation component 10 cannot provide the heat dissipation component 20 with the working voltage required for its operation, and the heat dissipation component 20 is in a non-working state.

[0035] The heat dissipation system 100 of the embodiment of the present disclosure drives the heat dissipation component 20 to work when the temperature difference between the cold end 102 and the hot end 101 of the temperature difference power generation component 10 reaches a temperature threshold, that is, the heat dissipation system 100 can control the working state of the heat dissipation component 20 according to the temperature difference at two different positions of the heating device 1000, so that the heat dissipation component 20 only dissipates heat to the heating device 1000 when the temperature difference at two different positions of the heating device 1000 is large, and does not dissipate heat to the heating device 1000 when the temperature difference at two different positions of the heating device 1000 is small, thereby avoiding the heat dissipation component 20 at the heating device 1000. 00 is always in working state during the working process, reducing the use time of the heat dissipation component 20, increasing the service life of the heating device 1000, and reducing the noise generated by the long-term use of the heat dissipation component 20; avoiding the heat dissipation component 20 to stop dissipating heat immediately when the heating device 1000 stops working, ensuring that the heat dissipation component 20 continues to work after the heating device 1000 stops working, until the temperature difference between two different positions of the heating device 1000 cannot reach the temperature difference threshold and the heat dissipation component 20 stops working, so that the heating device 1000 can dissipate heat sufficiently, and increase the service life of other parts of the heating device 1000 in the heating environment. At the same time, the temperature difference power generation component 10 of the heat dissipation system 100 of this embodiment uses the temperature difference to provide electric energy for the heat dissipation component 20, which can reduce the consumption of electric energy and save electric energy; in addition, the hot end 101 of the temperature difference power generation component 10 can absorb the heat of its surrounding environment, that is, the hot end 101 of the temperature difference power generation component 10 can take away part of the heat around the hot end 101, thereby improving the heat dissipation efficiency of the heat dissipation system 100.

[0036] It should be noted that the cold end 102 and the hot end 101 of the thermoelectric power generation component 10 are respectively arranged at two different positions of the heating device 1000, wherein the two different positions refer to two positions with a large temperature difference. For example, the heating device 1000 is an oven, the hot end 101 of the thermoelectric power generation component 10 is arranged in the heating chamber of the oven, and the cold end 102 of the thermoelectric power generation component 10 is arranged on the outer wall of the oven.

[0037] In some embodiments of the present disclosure, Figure 2As shown, the thermoelectric power generation component 10 includes: a first conductive member 11, a second conductive member 12 and a first connecting electrode 13, wherein the first conductive member 11 and the second conductive member 12 are made of different materials, the first end of the first conductive member 11 and the first end of the second conductive member 12 jointly form a hot end 101 of the thermoelectric power generation component 10, and the first end of the first conductive member 11 and the first end of the second conductive member 12 are electrically connected through the first connecting electrode 13, and the second end of the first conductive member 11 and the second end of the second conductive member 12 jointly form a cold end 102 of the thermoelectric power generation component 10. When the temperature of the hot end 101 of the thermoelectric power generation component 10 is greater than the temperature of its cold end 102, the electron movement speed of the hot end 101 is accelerated, the hot end 101 will be positively charged, and the cold end 102 will be negatively charged, and a potential difference will occur between the cold end 102 and the hot end 101 of the thermoelectric power generation component 10.

[0038] Further, the power supply input end of the heat dissipation component 20 includes a first power supply input end 201 and a second power supply input end 202. The second end of the first conductive member 11 is electrically connected to the first power supply input end 201 of the heat dissipation component 20, and the second end of the second conductive member 12 is electrically connected to the second power supply input end 202. The second end of the first conductive member 11 and the second end of the second conductive member 12 input the voltage generated by the hot end 101 and the cold end 102 into the heat dissipation component 20 through the second end of the first conductive member 11 and the second end of the second conductive member 12, respectively, to drive the heat dissipation component 20 to work.

[0039] In some embodiments of the present disclosure, Figure 2 As shown, the thermoelectric power generation component 10 also includes two second connecting electrodes 14, one end of one of the second connecting electrodes 14 is electrically connected to the second end of the first conductive member 11, and the other end of one of the second connecting electrodes 14 is electrically connected to the first power supply input terminal 201, that is, the two ends of one of the second connecting electrodes 14 are electrically connected to the second end of the first conductive member 11 and the first power supply input terminal 201, respectively; one end of the other second connecting electrode 14 is electrically connected to the second end of the second conductive member 12, and the other end of the other second connecting electrode 14 is electrically connected to the second power supply input terminal 202, that is, the two ends of the other second connecting electrode 14 are electrically connected to the second end of the second conductive member 12 and the second power supply input terminal 202, respectively. That is, one of the second connecting electrodes 14 electrically connects the first conductive part 11 of the thermoelectric power generation component 10 with the first power supply input electrode of the heat dissipation component 20, and the other second connecting electrode 14 electrically connects the second conductive part 12 of the thermoelectric power generation component 10 with the second power supply input electrode of the heat dissipation component 20. The two second connecting electrodes 14 are the power generation output ends of the thermoelectric power generation component 10, and the cold end 102 of the thermoelectric power generation component 10 is electrically connected to the heat dissipation component 20 through the two second connecting electrodes 14 to input the voltage generated by the thermoelectric power generation component 10 into the heat dissipation component 20.

[0040] In some embodiments of the present disclosure, one of the first conductive member 11 and the second conductive member 12 is a P-type semiconductor, and the other of the first conductive member 11 and the second conductive member 12 is an N-type semiconductor. The first end of the P-type semiconductor and the first end of the N-type semiconductor form a hot end 101, and are connected through the first connecting electrode 13 to form a PN junction, and the second end of the P-type semiconductor and the second end of the N-type semiconductor form a cold end 102. The hot end 101 is placed in a high temperature environment of the heating device 1000, such as a heating chamber of the heating device 1000, and the cold end 102 is placed in a low temperature environment of the heating device 1000, such as an outer wall of the heating device 1000. Due to thermal excitation, the hole (electron) concentration of the hot end 101 of the P-type semiconductor is higher than the hole (electron) concentration of the cold end 102 of the P-type semiconductor, and the hole (electron) concentration of the hot end 101 of the N-type semiconductor is higher than the hole (electron) concentration of the cold end 102 of the N-type semiconductor. Driven by this hole (electron) concentration gradient, holes and electrons diffuse from the hot end 101 to the cold end 102, thereby forming an electromotive force, that is, both the P-type semiconductor and the N-type semiconductor convert the thermal energy input from the hot end 101 into electrical energy through the temperature difference between the hot end 101 and the cold end 102.

[0041] In some embodiments of the present disclosure, the heat dissipation assembly 20 includes: a heat dissipation fan and a drive circuit (such as Figure 3 As shown, the temperature difference power generation component 10 is electrically connected to the heat dissipation fan through a driving circuit. Specifically, the two second connection electrodes 14 of the temperature difference power generation component 10 are electrically connected to the input end of the driving circuit, and the output ends FAN_VCC and FAN_GND of the driving circuit are electrically connected to the heat dissipation fan, and the temperature difference power generation component 10 drives the heat dissipation fan to work through the driving circuit.

[0042] In some embodiments of the present disclosure, the heat dissipation system 100 further includes a voltage stabilizing circuit (eg Figure 4 As shown), the thermoelectric power generation component 10 is electrically connected to the driving circuit through a voltage stabilizing circuit. Specifically, the two second connection electrodes 14 of the thermoelectric power generation component 10 are electrically connected to the input terminals VCC and GND of the voltage stabilizing circuit, the output terminals 5V and GND of the voltage stabilizing circuit are electrically connected to the input terminals 5V and GND of the driving circuit respectively, and the output terminals FAN_VCC and FAN_GND of the driving circuit are electrically connected to the heat dissipation fan. The thermoelectric power generation component 10 converts the output voltage of the thermoelectric power generation component 10 into a 5V voltage through the voltage stabilizing circuit and stably outputs it to the driving circuit, and the driving circuit drives the heat dissipation fan to work.

[0043] like Figure 1 As shown, the second aspect of the present disclosure proposes a heating device 1000 , and the heating device 1000 includes a heat dissipation system 100 according to any of the above embodiments.

[0044] The heating device 1000 of the embodiment of the present disclosure includes a heat dissipation system 100. The heat dissipation system 100 drives the heat dissipation component 20 to work when the temperature difference between the cold end 102 and the hot end 101 of the temperature difference power generation component 10 reaches a temperature threshold. That is, the heat dissipation system 100 can control the working state of the heat dissipation component 20 according to the temperature difference at two different positions of the heating device 1000, so that the heat dissipation component 20 only dissipates heat for the heating device 1000 when the temperature difference at two different positions of the heating device 1000 is large, and does not dissipate heat for the heating device 1000 when the temperature difference at two different positions of the heating device 1000 is small, thereby avoiding the heat dissipation component 20 from being heated. 20 is always in working state during the working process of the heating device 1000, reducing the use time of the heat dissipation component 20, increasing the service life of the heating device 1000, and reducing the noise generated by the long-term use of the heat dissipation component 20; avoiding the heat dissipation component 20 to stop dissipating heat immediately when the heating device 1000 stops working, ensuring that the heat dissipation component 20 continues to work after the heating device 1000 stops working, until the temperature difference between two different positions of the heating device 1000 cannot reach the temperature difference threshold and the heat dissipation component 20 stops working, so that the heating device 1000 can dissipate heat sufficiently, and increase the service life of other parts of the heating device 1000 in the heating environment. At the same time, the temperature difference power generation component 10 of the heat dissipation system 100 of this embodiment uses the temperature difference to provide electric energy for the heat dissipation component 20, which can reduce the consumption of electric energy and save electric energy; in addition, the hot end 101 of the temperature difference power generation component 10 can absorb the heat of its surrounding environment, that is, the hot end 101 of the temperature difference power generation component 10 can take away part of the heat around the hot end 101, thereby improving the heat dissipation efficiency of the heat dissipation system 100.

[0045] In some embodiments of the present disclosure, Figure 1 As shown, the heating device 1000 includes a housing 200, and the thermoelectric power generation component 10 and the heat dissipation component 20 are both arranged in the housing 200. Specifically, the housing 200 has a heating chamber (not shown in the figure), and the thermoelectric power generation component 10 and the heat dissipation component 20 are both arranged close to the heating chamber. The thermoelectric power generation component 10 converts the heat of the heating chamber into electrical energy to drive the heat dissipation component 20 to work. Further, the hot end 101 of the thermoelectric power generation component 10 is arranged on the inner side of the housing 200 and close to the heating chamber, or the hot end 101 is arranged in the heating chamber, and the cold end 102 of the thermoelectric power generation component 10 is arranged on the outer side of the housing 200, such as on the outer wall of the housing 200. The hot end 101 of the thermoelectric power generation component 10 is close to the heat source of the heating device 1000, and the cold end 102 is arranged on the outer wall of the housing 200. The heat dissipation component 20 is driven to work by the temperature difference between the cold end 102 and the hot end 101, so as to dissipate heat from the heating chamber of the heating device 1000.

[0046] Specifically, the cold end 102 of the thermoelectric power generation component 10 is bonded to the outer wall of the shell 200 by thermal conductive silicone grease, wherein the thermal conductive silicone grease is also called heat dissipation paste, thermal conductive paste, and the thermal conductive silicone grease has low oil separation (approaching zero), is resistant to high and low temperatures, water, ozone, and weather aging, and can maintain the grease state during use for a long time at a temperature of -50°C to +230°C. The thermal conductive silicone grease has high thermal conductivity, excellent thermal conductivity, good electrical insulation (only for insulating thermal conductive silicone grease), a wide operating temperature, good stability in use, low viscosity and good construction performance. The thermal conductive silicone grease is mainly used for heat conduction and heat dissipation between the cold end 102 of the thermoelectric power generation unit and the oven body, thereby ensuring the stability of the electrical performance of the thermoelectric power generation unit.

[0047] In some embodiments of the present disclosure, Figure 1 As shown, the heating device 1000 also includes a circuit board 300, and the circuit board 300 is arranged on the inner side of the shell 200. The heat dissipation component 20 is arranged close to the circuit board 300, that is, the heat dissipation component 20 is not only close to the heating cavity of the shell 200 but also close to the circuit board 300. The heat dissipation component 20 can dissipate heat for the heating cavity and the circuit board 300 to ensure that the temperature of the circuit board 300 is not too high, thereby improving the service life of the circuit board 300.

[0048] In some embodiments of the present disclosure, Figure 1 As shown, the hot end 101 of the temperature difference power generation component 10 is arranged near the circuit board 300. The hot end 101 of the temperature difference power generation component 10 is arranged near the circuit board 300, and can obtain heat near the circuit board 300. The heat dissipation fan near the circuit board 300 is driven to work according to the temperature difference between the hot end 101 near the circuit board 300 and the cold end 102 on the outer wall of the shell 200, that is, the circuit board 300 is cooled according to the temperature around the circuit board 300, to ensure that the temperature of the heat sink is not too high, thereby improving the service life of the circuit board 300.

[0049] It should be noted that the heating device in this embodiment can be an oven, a steam-bake combination machine or other equipment capable of heating, and this embodiment does not specifically limit the type of heating device.

[0050] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present disclosure, but the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and substance of the present disclosure, and these modifications and improvements are also considered to be within the scope of protection of the present disclosure.
