DETAILED DESCRIPTION

[0042] The following is combined with Figures 1 to 8 This application is described in further detail.

[0043] The present application embodiment discloses a film heating and heat dissipation structure. Figure 1 and Figure 2The membrane heating and heat dissipation structure includes a box body 1, a heater 2, a heat dissipation component 3 and a sealing component 4. A square mounting groove 11 is integrally formed at one end of the box body 1. A flow channel 12 that is concave inwards is integrally formed at the middle of the bottom of the mounting groove 11. The flow channel 12 can allow a fluid medium to flow therein. In this embodiment, the fluid medium can be a heatable liquid including a refrigerant, ethylene glycol, water, etc. The flow rate in the flow channel 12 is 5-20L / min, and the flow velocity is about 0.5m / s-3m / s.

[0044] The heater 2 is detachably mounted in the mounting groove 11, and the heater 2 can heat the fluid medium in the flow channel 12. The heat dissipation component 3 is mounted between the heater 2 and the flow channel 12, and the two ends of the heat dissipation component 3 are respectively attached to the heater 2 and the flow channel 12, and the heat dissipation component 3 can transfer the heat emitted from the heater 2 to the fluid medium in the flow channel 12. The sealing component 4 is mounted between the mounting groove 11 and the heater 2, and the sealing component 4 can seal between the flow channel 12 and the heater 2. In this embodiment, the heat dissipation component 3 is elastic.

[0045] Reference Figure 3 Preferably, a liquid inlet pipe 13 and a liquid outlet pipe 14 are fixed at one end of the housing 1, and both ends of the flow channel 12 are connected to the liquid inlet pipe 13 and the liquid outlet pipe 14 respectively. The fluid medium flows into the flow channel 12 from the liquid inlet pipe 13, and the heater 2 can transfer heat to the flow channel 12 through the heat dissipation component 3, thereby heating the fluid medium flowing in the flow channel 12, and the heated fluid medium is discharged from the liquid outlet pipe 14.

[0046] In addition, a liquid inlet probe 131 is installed in the liquid inlet pipe 13, and the liquid inlet probe 131 is located near the flow channel 12. A liquid outlet probe 141 is installed in the liquid outlet pipe 14, and the liquid outlet probe 141 is also located near the flow channel 12. In this embodiment, the liquid inlet probe 131 and the liquid outlet probe 141 are both temperature sensors. The liquid inlet probe 131 can collect the temperature of the liquid entering the flow channel 12, and the liquid outlet probe 141 can collect the temperature of the liquid flowing out of the flow channel 12. By collecting the temperature of the fluid flowing in and out, the product heating electric power is controlled.

[0047] Furthermore, the flow channel 12 is of S-shaped design, and includes a plurality of alternately arranged straight channels 121 and curved channels 122, the straight channels 121 and the curved channels 122 are interconnected, and the flow directions of the fluid medium in two adjacent straight channels 121 are opposite. In this embodiment, the number of straight channels 121 is four, and the number of curved channels 122 is three.

[0048] The S-shaped flow channel 12 can not only increase the contact area between the fluid medium and the heat dissipation component 3, but also increase the flow time of the fluid medium in the flow channel 12, thereby smoothly heating the fluid medium to a desired temperature.

[0049] Reference Figure 3 and Figure 4 Preferably, the heat dissipation assembly 3 includes a plurality of first heat sinks 31 and a plurality of second heat sinks 32, the plurality of first heat sinks 31 are all located in the straight channel 121, the first heat sinks 31 are arranged along the length direction of the straight channel 121, the plurality of second heat sinks 32 are all located in the curved channel 122, the arrangement direction of the second heat sinks 32 is perpendicular to the arrangement direction of the first heat sinks 31, in this embodiment, the number of the first heat sinks 31 is four, the number of the second heat sinks 32 is three, and the first heat sinks 31 and the second heat sinks 32 are both stamped from an elastic metal material.

[0050] Reference Figure 3 and Figure 5 The first heat sink 31 includes a first clamping portion 311, a first connecting portion 312 and a first elastic tongue portion 313. The first clamping portion 311, the first connecting portion 312 and the first elastic tongue portion 313 are integrally formed. The cross-section of the first clamping portion 311 is U-shaped. Both ends of the first clamping portion 311 are first connecting portions 312. The ends of the two first connecting portions 312 away from the first clamping portion 311 are multiple first elastic tongue portions 313, and a gap is left between two adjacent first elastic tongue portions 313. The cross-section of the first elastic tongue portion 313 is L-shaped. The angle of the bending part of the first elastic tongue portion 313 is an acute angle. The end of the first elastic tongue portion 313 away from the first connecting portion 312 is pressed against one side of the heater 2. A first clamping block 1211 is fixed at the straight road 121, and the length direction of the first clamping block 1211 is parallel to the length direction of the straight road 121. A first clamping groove 1212 is provided at one end of the first clamping block 1211 away from the straight road 121, and the length direction of the first clamping groove 1212 is parallel to the length direction of the first clamping block 1211. The first clamping block 1211 is clamped and matched with the first clamping portion 311 of the first heat sink 31 through the first clamping groove 1212, and a plurality of first hollow grooves 1213 are provided at the bottom of the first clamping groove 1212.

[0051] When assembling the first heat sink 31, the first clamping portion 311 of the first heat sink 31 is aligned with the first clamping groove 1212 of the first clamping block 1211, so that the first clamping portion 311 can be clamped in the first clamping groove 1212, so that the two ends of the first clamping portion 311 can clamp the first clamping block 1211, and because the distance between the first connecting portion 312 and the end of the first elastic tongue portion 313 that is away from each other is greater than the depth of the straight road 121, when the heater 2 is installed in the installation groove 11, the first clamping portion 311 can be clamped in the first clamping groove 1212, so that the two ends of the first clamping portion 311 can clamp the first clamping block 1211. A heat sink 31 is properly extruded so that the first connecting portion 312 can be tightly attached to the bottom of the straight track 121. Since the first heat sink 31 is elastic and the cross-section of the first spring tongue portion 313 is designed to be L-shaped, the first spring tongue portion 313 is deformed after being compressed, so that the multiple first spring tongue portions 313 located on both sides of the first clamping portion 311 are close to each other, so as to increase the contact area between the first spring tongue portion 313 and the heater 2, thereby increasing the contact area between the first heat sink 31 and the heater 2.

[0052] In addition, the first clamping block 1211 can not only clamp the first heat sink 31, but also increase the heat dissipation area inside the straight channel 121, effectively improving the thermal conversion efficiency of the product. Since there is a gap between two adjacent first elastic tongue portions 313 and multiple first hollow grooves 1213 are provided, the turbulence degree of the fluid medium can be increased. In the turbulent state, the micro-group movement of the fluid medium is more random, which can effectively disrupt the thermal boundary layer and promote the mixing and transfer of heat, thereby improving the thermal conversion efficiency. In addition, since the multiple first elastic tongue portions 313 located on both sides of the first clamping portion 311 are close to each other, the turbulence degree will be further aggravated.

[0053] Reference Figure 6 and Figure 7Furthermore, the second heat sink 32 includes a second plug-in portion 321 and a second elastic tongue portion 322, the second plug-in portion 321 and the second elastic tongue portion 322 are integrally formed, the second plug-in portion 321 is plugged into the bend 122, the length direction of the second plug-in portion 321 is perpendicular to the length direction of the first clamping portion 311, the second elastic tongue portion 322 is located at both ends of the second plug-in portion 321, and multiple second elastic tongue portions 322 are arranged along the length direction of the second elastic tongue portion 322, and a gap is left between two adjacent second elastic tongue portions 322. The cross-section of the second elastic tongue portion 322 is also L-shaped, and the angle of the bending part of the second elastic tongue portion 322 is an obtuse angle. The end of the second elastic tongue portion 322 away from the second plug-in portion 321 is pressed against one side of the heater 2. A second clamping block 1221 is fixed at the curve 122, and the second clamping block 1221 is arc-shaped, and the arc-shaped trend of the second clamping block 1221 is adapted to the arc-shaped trend of the curve 122, a plug-in block 1222 is fixed on the second clamping block 1221, a plug-in hole 3211 is provided on the second plug-in portion 321, and the plug-in block 1222 on the second clamping block 1221 is plugged into and matched with the plug-in hole 3211 on the second plug-in portion 321.

[0054] When assembling the second heat sink 32, align the plug hole 3211 of the second plug portion 321 with the plug block 1222 of the second clamping block 1221, so that the plug block 1222 is inserted into the plug hole 3211. Since the distance between the ends of the second plug portion 321 and the second spring tongue portion 322 that are away from each other is greater than the depth of the bend 122, the second heat sink 32 can be properly squeezed when the heater 2 is installed in the mounting groove 11. Since the second heat sink 32 is elastic and the cross-section of the second spring tongue portion 322 is designed to be L-shaped, the second spring tongue portion 322 is deformed after being pressed, so that the multiple second spring tongue portions 322 located on both sides of the second plug portion 321 are away from each other, so as to increase the contact area between the second spring tongue portion 322 and the heater 2, thereby increasing the contact area between the second heat sink 32 and the heater 2.

[0055] Reference Figure 7 In addition, an inner guide block 1223 and an outer guide block 1224 are fixed at the curve 122 and on both sides of the second clamping block 1221, respectively. The inner guide block 1223 is located at the inner bend of the curve 122, and the outer guide block 1224 is located at the outer bend of the curve 122. The inner guide block 1223 and the outer guide block 1224 are both arc-shaped, and the arc trends of the inner guide block 1223 and the outer guide block 1224 are adapted to the arc trends of the curve 122. Limiting blocks 1225 are fixed in the curve 122 and at both ends of the outer guide block 1224. The limiting blocks 1225 are arc-shaped, and the arc trends of the limiting blocks 1225 are adapted to the arc trends of the curve 122, and a space is left between the limiting blocks 1225 and the outer guide blocks 1224.

[0056] Since the inner guide block 1223 and the outer guide block 1224 correspond to the positions of the second elastic tongue portions 322 at both ends of the second plug-in portion 321, the second elastic tongue portion 322 at the middle portion can be limited to a certain extent, so that the second elastic tongue portion 322 at the middle portion is not easily deformed excessively. Since the two limiting blocks 1225 are respectively located at the positions of the two second elastic tongue portions 322 at the end positions, the second elastic tongue portions 322 at the end portions can be limited to a certain extent, so that the second elastic tongue portions 322 at the end portions are not easily deformed excessively.

[0057] Since the second clamping block 1221, the inner guide block 1223, the outer guide block 1224 and the limit block 1225 are all arranged in an arc shape, the fluid medium flowing through the bend 122 can be guided, so that the fluid medium passes through the bend 122 more smoothly, thereby reducing the kinetic energy loss of the fluid medium.

[0058] In addition, the second heat sink 32 also includes a plurality of third elastic tongue portions 323 integrally formed with the second plug-in portion 321. After the second heat sink 32 is installed on the bend 122, the third elastic tongue portions 323 can be located in the space reserved between the limit block 1225 and the outer guide block 1224, and the third elastic tongue portions 323 face the bend 122. When the fluid medium flows through the bend 122, it can contact the third elastic tongue portions 323 on the second heat sink 32 and transfer heat to the fluid medium. The provision of the third elastic tongue portions 323 can increase the contact area between the second heat sink 32 and the fluid medium, thereby improving the heat conversion efficiency.

[0059] Reference Figure 2 Preferably, a connecting plate 21 is fixed to the outside of the heater 2, and a plurality of screws 211 are connected between the connecting plate 21 and the mounting groove 11, and the screws 211 are threadedly arranged on the connecting plate 21 and the mounting groove 11. The setting of the connecting plate 21 facilitates the installation of the screws 211, and the setting of the screws 211 can realize a detachable connection between the connecting plate 21 and the mounting groove 11, thereby realizing a detachable connection between the heater 2 and the box body 1, which is easy and convenient to disassemble, and is convenient for disassembly, assembly, and replacement of the heater 2, the first heat sink 31, and the second heat sink 32, without damaging any product.

[0060] Reference Figure 2 and Figure 3 In addition, a plurality of limiting plugs 111 are fixed to the bottom of the installation groove 11, and a plurality of limiting plug holes 212 are provided on the connection plate 21, and the limiting plug holes 212 are plugged and matched with the limiting plugs 111. When installing the heater 2, the limiting plug holes 212 on the connection plate 21 are first aligned with the limiting plugs 111 to facilitate positioning of the connection plate 21. After the heater 2 is installed, the limiting plugs 111 and the limiting plug holes 212 can improve the stability of the heater 2.

[0061] Reference Figure 3 and Figure 8 Further, the sealing assembly 4 includes a sealing groove 41, a sealing gasket 42 and an elastic protrusion 43. The sealing groove 41 is opened in the installation groove 11, and the sealing groove 41 is located at the periphery of the flow channel 12. The sealing grooves 41 are connected end to end. The cross section of the sealing groove 41 is square. The sealing gasket 42 is installed in the sealing groove 41. The cross section of the sealing gasket 42 is also square. In the natural state, the thickness of the sealing gasket 42 is slightly greater than the depth of the sealing groove 41. The elastic protrusion 43 is fixed to the inner and outer sides of the sealing gasket 42, and multiple protrusions 43 are arranged.

[0062] After installing the heat dissipation component 3 in the flow channel 12, the sealing gasket 42 is installed in the sealing groove 41 so that the elastic protrusion 43 is pressed against the sealing groove 41. Since the thickness of the sealing gasket 42 is slightly greater than the depth of the sealing groove 41, the sealing gasket 42 will slightly protrude from the sealing groove 41. When the heater 2 is fastened in the installation groove 11 by the screw 211, the sealing gasket 42 will be squeezed by the heater 2, so that the sealing gasket 42 seals the heater 2 and the flow channel 12. At the same time, the heater 2 can also squeeze the first heat sink 31 and the second heat sink 32.

[0063] Reference Figure 2 and Figure 3 Preferably, a cover plate 15 is installed on the box body 1, and the cover plate 15 covers the opening of the installation groove 11. A plurality of buckles 151 are fixed on the cover plate 15. A plurality of slots 152 are provided on the box body 1, and the buckles 151 on the cover plate 15 are engaged with the slots 152 on the box body 1. The setting of the cover plate 15 can cover the installation groove 11, thereby shielding all components in the box body 1, so as to protect the internal components of the box body 1.

[0064] Finally, it should be noted that the fluid medium inlet temperature of the present application is -40°C to 90°C, and the fluid medium outlet temperature is about 10-13°C higher than the fluid medium inlet temperature. In this embodiment, the heat transfer area is about 100,000 square millimeters.

[0065] The relationship between pressure, flow rate and temperature in the flow channel is shown in the following table:

[0066]

[0067] The implementation principle of the membrane heating and heat dissipation structure of the embodiment of the present application is: first, the heat dissipation component 3 is assembled in the flow channel 12 of the box body 1, and then the heat dissipation component 3 is assembled, and then the heater 2 is assembled, so that the heater 2 is fastened to one side of the flow channel 12. Since the heat dissipation component 3 is elastic, when the elastic heat dissipation component 3 is subjected to the compression force between the heater 2 and the flow channel 12, one side of the heat dissipation component 3 can be tightly matched with the heater 2, thereby increasing the heat dissipation area of ​​the heater 2 and effectively improving the thermal conversion efficiency of the heater 2; the setting of the screw 211 can realize a detachable connection between the heater 2 and the box body 1, which is easy and convenient to disassemble, and is convenient for disassembly, assembly and replacement of the heater 2, the first heat sink 31 and the second heat sink 32 without damaging any product.
