Description

Technical Field

[0001] This invention relates to the field of heat transfer technology, and in particular to a multifunctional superstructure heat flow controller. Background Technology

[0002] Thermal cloaks, thermal rotators, and thermal concentrators are three types of thermal functional devices capable of manipulating heat flow. They can manipulate heat flow without altering the temperature distribution of the background field, thus achieving non-invasive heat flow control. A thermal cloak can guide background heat flow around protected objects in the control area, making them invisible from an infrared detection perspective; a thermal concentrator can concentrate heat flow into the control area, enhancing the heat flow in that area to be greater than the background heat flow; and a thermal rotator can rotate the heat flow within the control area to form a certain angle with the background heat flow.

[0003] If these three components could be integrated into a single device, this integrated device would offer greater flexibility in controlling heat flow. However, to simultaneously achieve these three functions, the thermal conductivity of the material needs to change by three orders of magnitude, and materials that meet this requirement are currently difficult to find or prepare. Therefore, it is currently difficult to integrate a thermal cloak, a thermal rotator, and a thermal concentrator into a single device. Summary of the Invention

The line connecting the two ends of the direction is the first straight line, the line connecting the center of the adjustment unit and the center of the control part is the second straight line, and the line perpendicular to the second straight line and passing through the center of the adjustment unit is the third straight line.

The multifunctional superstructure heat flow controller has a thermal stealth state, a thermal accumulation state, and a thermal rotation state. When the multifunctional superstructure heat flow controller is in the thermal stealth state, the rotation angle of the adjustment unit is 0° or 180°.

[0036] For ease of description, the "multifunctional superstructure heat flow controller" will be referred to as the heat flow controller in the following text. Figure 1 A heat flow regulator 101 according to a first embodiment of the present invention is shown. The heat flow regulator 101 includes a mounting plate 102 and a functional ring 105. The mounting plate 102 is used to contact a heat source and a cold source, and heat can be transferred through the mounting plate 102. For example, based on Figure 1 If the left end of the mounting plate 102 is immersed in hot water and the right end is immersed in cold water, heat will be transferred from left to right within the mounting plate 102. The state of the functional ring 105 relative to the mounting plate 102 is adjustable, and the heat conduction path can be changed by altering the state of the functional ring 105.

[0037] like Figure 1 As shown, the mounting plate 102 includes a background portion 103 and a control portion 104, which are spaced apart. The background portion 103 is located around the periphery of the control portion 104. A functional ring 105 is disposed between the background portion 103 and the control portion 104, and surrounds the outer periphery of the control portion 104. Specifically, an annular groove is formed on the top surface of the mounting plate 102, dividing the mounting plate 102 into the background portion 103 and the control portion 104, and the functional ring 105 is disposed within the groove. Figure 1The heat flow regulator 101 in only includes one functional loop 105. The functional loop 105 includes multiple regulating units 106. The regulating units 106 are distributed along the circumferential direction of the control part 104, and the multiple regulating units 106 surround the outer periphery of the control part 104. The regulating unit 106 can rotate relative to the mounting plate 102, so as to change the rotation angle of the regulating unit 106, and further change the state of the heat flow regulator 101. The regulating unit 106 can be rotated by hand by the user. Alternatively, in some other embodiments, the regulating unit 106 can be rotated under the driving action of a driving component such as a motor, so as to save manpower and improve the efficiency of state switching of the heat flow regulator 101. The regulating unit 106 includes a first part 107 and a second part 108 which are connected to each other. If the thermal conductivity of the first part 107 is denoted as k1, and the thermal conductivity of the second part 108 is denoted as k2, then k1 < k2.

[0038] The rotation angle of the regulating unit 106 will be explained below by taking Figure 2 as an example. Figure 2 FIG. shows the control part 104 and one of the regulating units 106. Referring to Figure 2 , observing along the axial direction of the regulating unit 106: The first part 107 and the second part 108 are distributed along the width direction of the second part 108. The connection line between the two ends of the second part 108 along its own length direction is the first straight line 201. The connection line between the center of the regulating unit 106 and the center of the control part 104 is the second straight line 202. The straight line perpendicular to the second straight line 202 and passing through the center of the regulating unit 106 is the third straight line 203. The included angle between the first straight line 201 and the third straight line 203 is the rotation angle, and the rotation angle is represented by θ. It should be noted that the "axial direction of the regulating unit 106" can correspond to Figure 1 the direction perpendicular to the paper surface of Figure 2 , and the direction perpendicular to the paper surface of . The above explanation of the rotation angle of the regulating unit 106 is for a single regulating unit 106. Different regulating units 106 have their respective corresponding first straight lines 201, second straight lines 202 and third straight lines 203.

[0039] In the process of heat transfer from the background part 103 to the control part 104, the heat needs to pass through the functional loop 105. Since k1 < k2, the heat conduction ability of the second part 108 is stronger than that of the first part 107. The heat that needs to pass through the functional loop 105 mainly flows to the control part 104 through the second part 108. Therefore, the angles and positions of the second part 108 and the first part 107 determine the heat transfer path when the heat transfers from the background part 103 to the control part 104. That is, the rotation angle of the regulating unit 106 determines the heat transfer path.

[0040] With the temperature field of the background part 103 remaining unchanged, changing the rotation angle of the adjustment unit 106 can change the temperature field of the control part 104, thereby putting the heat flow controller 101 into a thermal stealth state, a thermal accumulation state, and a thermal rotation state. Figure 3 The diagram shows thermal simulations of the heat flow controller 101 in thermal stealth, thermal accumulation, and thermal rotation states.

[0041] Figure 3 The temperature field of the heat flow controller 101 is shown. Figure 3 The left side of the mounting plate 102 is a high-temperature area, and the right side of the mounting plate 102 is a low-temperature area. Heat is conducted from the left side of the mounting plate 102 to the right side of the mounting plate 102.

[0042] like Figure 3 As shown in (a), when the heat flow controller 101 is in a thermal stealth state, the rotation angle θ = 0° or 180°. At this time, in the same regulating unit 106, the first part 107 and the second part 108 are radially distributed along the control part 104, and the line connecting the two ends of the second part 108 along its own length extends tangentially along the control part 104. Furthermore, two adjacent second parts 108 arranged circumferentially along the control part 104 are in contact with each other (the two contacting second parts 108 belong to different regulating units 106). Therefore, after the heat from the background part 103 is conducted to the regulating unit 106, the heat is mainly conducted circumferentially along the functional ring 105, and less heat enters the control part 104 from the functional ring 105. The temperature field of the control part 104 is less affected by the temperature field of the background part 103. Figure 3 As shown in (a), the control part 104 has fewer isotherms 204, and the temperature field distribution of the control part 104 differs significantly from that of the background part 103. The temperature field of the control part 104 is less affected by the temperature field of the background part 103. Therefore, the heat flow controller 101 in the thermal stealth state acts as a thermal stealth cloak.

[0043] like Figure 3 As shown in (b), when the heat flow regulator 101 is in a heat accumulation state, the rotation angle θ = 90°. At this time, in the same regulating unit 106, the first portion 107 and the second portion 108 are distributed circumferentially along the control portion 104, and the line connecting the two ends of the second portion 108 along its own length extends radially along the control portion 104. Furthermore, two first portions 107 arranged adjacent to each other circumferentially along the control portion 104 are in contact with each other (the two contacting second portions 108 belong to different regulating units 106). Therefore, after the heat from the background portion 103 is conducted to the regulating unit 106, the heat is conducted radially along the control portion 104 and enters the control portion 104, whereby the heat can be accumulated. Figure 3As shown in (b), the density of isotherms 204 in the control section 104 is higher than that in the background section 103, thus enhancing the heat flow in the control section 104. Therefore, the heat flow regulator 101, when in a state of heat accumulation, functions as a heat concentrator.

[0044] like Figure 3 As shown in (c), when the rotation angle θ is acute or obtuse, the heat flow controller 101 is in a thermal rotation state. After the heat from the background portion 103 is conducted to the regulating unit 106, the heat is conducted along the length of the second portion 108 and enters the control portion 104. The direction of heat flow in the control portion 104 is different when θ = 90°, as it is when θ is acute or obtuse. Figure 3 As shown in (c), when the heat flow controller 101 is in a thermal rotation state, the arrangement direction of the isotherms 204 in the control section 104 is different from that in the background section 103. This means that the heat flow direction of the control section 104 and the heat flow direction of the background section 103 have a certain angle. Therefore, the heat flow controller 101 in a heat accumulation state acts as a thermal rotator. Furthermore, while ensuring that the rotation angle is acute or obtuse, the angle between the heat flow direction of the control section 104 and the heat flow direction of the background section 103 can be changed by changing the size of the rotation angle.

[0045] In summary, the heat flow regulator 101 of the present invention combines the functions of a thermal cloak, a heat concentrator, and a heat rotator. This heat flow regulator 101 can be applied to the thermal management of objects. Taking a battery as an example, several batteries can be installed on the control section 104. When the battery needs to be insulated from the background section 103, the heat flow regulator 101 can be switched to a thermal cloak state to reduce the impact of the heat from the background section 103 on the battery. When the battery needs to be heated (e.g., when the battery is in a low-temperature environment), the heat flow regulator 101 can be switched to a heat concentrator state to increase the heat flow density of the control section 104, thereby heating the battery. When it is necessary to ensure that multiple batteries at the control section 104 can be uniformly heated, it may be necessary to adjust the heat flow direction of the control section 104. In this case, the heat flow regulator 101 can be switched to a heat rotator state.

[0046] In some embodiments, multiple functional rings 105 may be provided, and for any two adjacent functional rings 105, one functional ring 105 is nested around the outer periphery of the other functional ring 105. For example... Figure 4 A heat flow regulator 101 according to a second embodiment of the present invention is shown. Figure 6 A heat flow regulator 101 is shown in the third embodiment of the present invention. The second embodiment includes two functional loops 105, and the third embodiment includes three functional loops 105. Figure 5 (a) Figure 5 (b) and Figure 5 (c) The temperature field distribution of the thermal device in the second embodiment is shown in the thermal stealth state, thermal accumulation state and thermal rotation state respectively; Figure 6 (a) Figure 6 (b) and Figure 6 (c) The temperature field distributions of the thermal device in the second embodiment are shown in the thermal stealth state, thermal accumulation state, and thermal rotation state, respectively. Figure 5 and Figure 6 It can be seen that the heat flow controller 101, when including multiple functional rings 105, can also function as a thermal cloak, a heat concentrator, and a heat rotator. Furthermore, increasing the number of functional rings 105 can improve the heat flow control effect of the heat flow controller 101. Taking the heat concentrating state as an example, ... Figure 3 (b) Figure 5 (b) and Figure 6 (b) By comparison, it can be concluded that the more functional rings 105 there are, the higher the density of isotherms 204 in the control part 104, and the stronger the heat flow in the control part 104.

[0047] In the first, second, and third embodiments, the adjustment unit 106 is cylindrical and can rotate around its central axis, with the outer peripheral surfaces of adjacent adjustment units 106 being tangent. In this case, regardless of the angle to which the adjustment unit 106 rotates, adjacent adjustment units 106 can maintain contact, thereby ensuring the stability of the heat flow control effect of the heat flow regulator 101. It should be noted that when the number of functional rings 105 is two or more, "the outer peripheral surfaces of adjacent adjustment units 106 being tangent" means that the outer peripheral surfaces of two adjacent adjustment units 106 within the same functional ring 105 are tangent, and the outer peripheral surfaces of two adjacent adjustment units 106 belonging to different functional rings 105 are also tangent. In other embodiments, the heat flow regulator 101 can also be configured as a prism, such as a hexagonal prism; the closer the shape of the adjustment unit 106 is to a cylinder, the better the heat flow control effect of the heat flow regulator 101.

[0048] In the first, second, and third embodiments, the adjustment unit 106 includes a second part 108 and two first parts 107. When viewed along the axial direction of the adjustment unit 106, the first parts 107 and the second parts 108 are alternately stacked. Figure 8 A top view of the adjustment unit 106 in the fourth embodiment is shown. Figure 8The adjustment unit 106 includes two second portions 108 and three first portions 107. Viewed along the axial direction of the adjustment unit 106, the first portions 107 and second portions 108 are alternately stacked. Of course, in some other embodiments, the number of second portions 108 and first portions 107 can be greater, which will not be listed here. The more first portions 107 and second portions 108 there are, the better the thermal stealth effect of the heat flow controller 101.

[0049] Figure 9 A top view of the adjustment unit 106 in the fifth embodiment is shown. Figure 5 The adjustment unit 106 includes only a first part 107 and a second part 108. When viewed along the axial direction of the adjustment unit 106, both the first part 107 and the second part 108 are semi-circular. This design helps to reduce the structural complexity of the heat flow controller 101.

[0050] The first part 107 can be made of resin material, more specifically, photosensitive resin, epoxy resin, etc. Resin material has a lower cost, which helps reduce the cost of the heat flow regulator 101. The second part 108 can be made of copper, silver, or gold. These metals have high thermal conductivity, which helps to increase the difference between k2 and k1, thereby increasing the heat flow regulator 101's control effect on heat flow. Of course, the second part 108 can also be made of other metal or non-metal materials with high thermal conductivity; examples are not given here. Furthermore, to further increase the difference between k2 and k1, in some embodiments, k1 can be less than 1 W / (m·K), and k2 can be greater than 100 W / (m·K).

[0051] When the regulating unit 106 is cylindrical, the heat flow controller 101 may also include a filler 109. For example... Figure 7 As shown, the filler 109 is disposed between the control portion 104 and the background portion 103, and the filler 109 is in contact with the outer peripheral surface of the adjustment unit 106. The thermal conductivity of the filler 109 is greater than 1 W / (m·K). To facilitate the differentiation of different components, Figure 7 The filler 109 is filled with a diagonal line, but it should be noted that... Figure 7 This is not a cross-sectional view. The background portion 103 and the control portion 104 are separated by an annular groove. The adjustment unit 106 is located in the annular groove, and the filler 109 is located in the annular groove and fills the space in the annular groove not occupied by the adjustment unit 106. More specifically, the filler 109 can be set as thermal grease. The thermal conductivity of the filler 109 is much greater than that of air (the thermal conductivity of air is 0.0267 W / (m·K)). The filler 109 helps to reduce the thermal resistance between the background portion 103 and the adjustment unit 106, as well as the thermal resistance between the adjustment unit 106 and the control portion 104.

[0052] If the thermal conductivity of the mounting plate 102 is denoted as k b , then k b can satisfy k1 < k b < k2. Such a setting can make the combined thermal impedance of the functional ring 105 and the filler 109 match the thermal impedance of the background part 103, so as to avoid the thermal conductivity of the background part 103 being too low or too high and affecting the heat flow regulation effect of the heat flow regulator 101. The mounting plate 102 can specifically be set as a metal plate, a plastic plate, etc.

[0053] In some embodiments, the heat flow regulator 101 further includes a driving mechanism. The driving mechanism 301 is connected to the adjusting unit 106, and the driving mechanism can drive all the adjusting units 106 to rotate synchronously. In this setting mode, when the state of the heat flow regulator 101 needs to be switched, the user does not need to manually turn the adjusting unit 106, and the state switching of the heat flow regulator 101 is more convenient. Moreover, when a driving mechanism is provided, the rotation angle of the adjusting unit 106 can be controlled more precisely to accurately regulate the heat flow.

[0054] Figure 10 and Figure 11 shows one of the driving mechanisms 301. Referring to Figure 10 , the driving mechanism 301 includes a motor 302, a central gear 303 and a plurality of peripheral gears 304. The central gear 303 and the peripheral gears 304 are both external gears (i.e., the teeth are located on the outer circumference of the gear). The plurality of peripheral gears 304 surround the outer circumference of the central gear 303, and the peripheral gears 304 mesh with the central gear 303. The motor 302 is connected to the central gear 303, and the peripheral gears 304 and the adjusting units 106 are connected in one-to-one correspondence. When the motor 302 drives the central gear 303 to rotate, all the peripheral gears 304 rotate synchronously, and all the adjusting units 106 also rotate synchronously.

[0055] As Figure 11 shown, if there are multiple functional rings 105, then the number of central gears 303 is equal to the number of functional rings 105. The peripheral gears 304 are arranged in multiple layers, and the number of layers of the peripheral gears 304 is equal to the number of central gears 303. The multiple central gears 303 are coaxially arranged, and the peripheral gears 304 in different layers are respectively wound around the outer circumference of different central gears 303. The peripheral gears 304 in the same layer are connected to the adjusting units 106 in the same functional ring 105 in one-to-one correspondence. In this way, the driving mechanism 301 can drive all the adjusting units 106 to rotate synchronously.

[0056] When using the heat flow controller 101, a temperature sensor can be installed on the control part 104 or on an object mounted on the control part 104. Both the temperature sensor and the drive mechanism 301 are communicatively connected to the controller. The drive mechanism 301 changes the rotation angle of the adjustment unit 106 according to the temperature detected by the temperature sensor. In this way, automatic regulation of heat flow can be achieved based on the temperature of the control part 104.
