Description

Technical Field

[0001] This invention relates to the field of oil-filled radiator technology, and more specifically, to an oil-filled radiator and a control method thereof. Background Technology

[0002] Currently, oil-filled radiators are increasingly being used for heating in homes and offices due to their more even heat distribution, better heating effect, and suitability for larger spaces. In existing technology, the heat sink fins of oil-filled radiators are typically fixed to the main body, and the heating temperature is adjusted using a three-level temperature control knob to change the radiator's temperature relative to the room temperature.

[0003] However, a fixed connection method means that the heat dissipation area of ​​the heat sink is also fixed. This means that the oil heater can only be adjusted according to the temperature setting on the temperature control knob, which makes the heating temperature of the oil heater relatively fixed. Furthermore, since the temperature required by the user may not be within the set setting, the user has to frequently turn the temperature control knob if they need to maintain a specific heating temperature, which will seriously affect the user experience. Summary of the Invention

[0023] Furthermore, the heat sink includes a connector, a transition section, and a heat dissipation body. The two ends of the transition section are connected to the connector and the heat dissipation body, respectively. Along the extension direction from the connector to the heat dissipation body, the flow cross-sectional area of ​​the transition section gradually decreases. The transmission connector includes:

[0024] A connecting rod, one end of which forms one end of a transmission connector;

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] Please refer to Figures 1 to 7 In Embodiment 1 of the present invention, an oil-filled radiator is provided, comprising a first connecting housing 11 and a second connecting housing 12 spaced apart, and a heat sink 20. The first connecting housing 11 has a first connecting cavity, the second connecting housing 12 has a second connecting cavity, and the heat sink 20 has a heat dissipation channel 21, one end of which communicates with the first connecting cavity, and the other end of which communicates with the second connecting cavity. One end of the heat sink 20 is rotatably mounted on the first connecting housing 11, and the other end of the heat sink 20 is rotatably mounted on the second connecting housing 12.

[0060] With this configuration, one end of the heat sink 20 is rotatably connected to the first connecting housing 11, and the other end of the heat sink 20 is rotatably connected to the second connecting housing 12. Furthermore, the heat dissipation channel 21 communicates with both the first and second connecting cavities. This allows for the use of rotatable connections instead of fixed welding without affecting the heat dissipation operation of the oil-filled radiator, enabling adjustable angles for the heat sink 20. When the user needs to enhance the heating effect, the heat sink 20 can be rotated in the first preset direction. Conversely, when the user needs to reduce the heating effect, the heat sink 20 can be rotated in the second preset direction, opposite to the first preset direction. This allows for more flexible control of the heating effect, thus solving the technical problem of inconvenient temperature adjustment in existing oil-filled radiators.

[0061] In this embodiment, the oil heater further includes a connecting structure 30. The connecting structure 30 includes a first connecting portion 31 and a second connecting portion 32. One end of the first connecting portion 31 is fixedly connected to the first communicating shell 11 or the second communicating shell 12, and one end of the second connecting portion 32 is fixedly connected to the portion of the heat sink 20 to be connected. The second connecting portion 32 is rotatably disposed relative to the first connecting portion 31. The other end of the second connecting portion 32 is sleeved on the other end of the first connecting portion 31, or the other end of the first connecting portion 31 is sleeved on the other end of the second connecting portion 32. This arrangement results in a simple structure and stable connection, enabling the heat sink 20 to be connected to the first communicating shell 11 or the second communicating shell 12 via the connecting structure 30. Furthermore, the rotatable nature of the second connecting portion 32 relative to the first connecting portion 31 further ensures the rotatability of the heat sink 20.

[0062] Specifically, the connecting structure 30 may further include a bearing structure 33, which is disposed between the first connecting portion 31 and the second connecting portion 32. This arrangement enables smoother and more stable rotation between the first connecting portion 31 and the second connecting portion 32, and also reduces wear between the first connecting portion 31 and the second connecting portion 32.

[0063] Alternatively, the connection structure 30 may also include a sealing structure 34, which is disposed between the first connection portion 31 and the second connection portion 32. This can effectively reduce leakage at the connection between the first connection portion 31 and the second connection portion 32, and prevent the heat-conducting medium inside the oil heater from leaking out of the oil heater.

[0064] Alternatively, the connecting structure 30 may also include an oil baffle ring 35, which is disposed between the first connecting portion 31 and the second connecting portion 32. With this arrangement, the oil baffle ring 35 can block the heat transfer medium inside the oil heater, thereby preventing leakage of the heat transfer medium.

[0065] Alternatively, the bearing structure 33, the sealing structure 34, and the oil retaining ring 35 can be provided simultaneously. This arrangement allows for smoother rotation between the first connecting part 31 and the second connecting part 32 while enhancing the sealing between them, effectively improving the stability of the oil heater during operation.

[0066] The heat transfer medium can be heat transfer oil or other media with low specific heat capacity, so that the oil heater can exchange heat with the environment.

[0067] In this embodiment, the connecting structure 30 may further include a first sealing member 341. A first mounting groove 311 adapted to the first sealing member 341 is provided on the first connecting portion 31. At least a portion of the first sealing member 341 is installed within the first mounting groove 311, and the first sealing member 341 is located between the first connecting portion 31 and the second connecting portion 32. Alternatively, the connecting structure 30 may further include a second sealing member 342. A second mounting groove 321 adapted to the second sealing member 342 is provided on the second connecting portion 32. At least a portion of the second sealing member 342 is installed within the second mounting groove 321, and the second sealing member 342 is located between the first connecting portion 31 and the second connecting portion 32. Alternatively, both the first sealing member 341 and the second sealing member 342 may be provided simultaneously, with the first sealing member 341 and the second sealing member 342 spaced apart. With this configuration, by providing a first seal 341 and a second seal 342 on the first connection portion 31 and the second connection portion 32 respectively, the flow of the heat-conducting medium can be further obstructed by the two seals, thereby further enhancing the sealing performance inside the oil heater.

[0068] Specifically, the first connecting part 31 is sleeved on the second connecting part 32. The first connecting part 31 is provided with a first mounting groove 311 and a second mounting groove 321 that are interconnected. The connecting structure 30 also includes a bearing structure 33 and an oil baffle ring 35. The bearing structure 33 is adapted to the shape of the first mounting groove 311 and is installed in the first mounting groove 311. The oil baffle ring 35 is adapted to the shape of the second mounting groove 321 and is installed in the second mounting groove 321. A first positioning step 3211 is provided in the second mounting groove 321. A second positioning step 3212 is provided at the connection between the mounting groove 321 and the first mounting groove 311; wherein, the oil baffle ring 35 has a first abutment part 351, an oil baffle part 352 and a second abutment part 353 connected in sequence. The oil baffle part 352 is attached to the outer wall of the second connecting part 32. The first abutment part 351 and the second abutment part 353 are both located on the side of the oil baffle part 352 away from the second connecting part 32. The first abutment part 351 abuts against the first positioning step 3211, and the second abutment part 353 is disposed between the second positioning step 3212 and the bearing structure 33. With this configuration, the structure of the first positioning step 3211 and the second positioning step 3212 in the second mounting groove 321 can obstruct the flow of liquid. Furthermore, since the first abutting part 351 and the second abutting part 353 abut against the first positioning step 3211 and the second positioning step 3212 respectively, the heat exchange medium can be further prevented from flowing through the first positioning step 3211 and the second positioning step 3212, thereby further improving the sealing performance between the first connecting part 31 and the second connecting part 32.

[0069] In this embodiment, the oil heater also includes a drive assembly 40, which includes a drive structure 41 and a transmission structure 42. The transmission input end of the transmission structure 42 is connected to the drive structure 41, and the transmission output end of the transmission structure 42 is connected to the heat sink 20. The transmission output end of the transmission structure 42 is rotatably configured to drive the heat sink 20 to rotate. This configuration facilitates driving the heat sink 20 via the drive assembly 40, preventing the user from directly rotating the heat sink 20 by hand and thus avoiding injury to the user due to the high temperature of the heat sink 20.

[0070] Among them, the drive structure 41 can be a motor.

[0071] Specifically, there are multiple heat sinks 20, which extend along the extension direction of the first connecting housing 11. The transmission structure 42 includes a transmission rod 421, a first bevel gear 422, a second bevel gear 423, and a transmission connector 424. The end of the transmission rod 421 forms the transmission input end of the transmission structure 42. The transmission rod 421 extends along the extension direction of the first connecting housing 11 or the second connecting housing 12. The first bevel gear 422 is mounted on the transmission rod 421 to drive the first bevel gear 422 to rotate. There are multiple first bevel gears 422, which are spaced apart along the extension direction of the transmission rod 421. The second bevel gear 423 cooperates with the first bevel gear 422 to drive the second bevel gear 423 to rotate. There are multiple second bevel gears 423, which are arranged one-to-one with the multiple first bevel gears 422, and each second bevel gear 423 cooperates with its corresponding first bevel gear 422. Multiple transmission connectors 424 are provided, with multiple second bevel gears 423 and multiple heat sinks 20 corresponding to each other. One end of each transmission connector 424 is connected to the corresponding second bevel gear 423, and the other end is connected to the corresponding heat sink 20. With this structure, when the drive structure 41 outputs power, it can drive the bevel gears of multiple sets of first bevel gears 422 and second bevel gears 423 through a single transmission rod 421, and drive the heat sinks 20 to rotate through multiple sets of transmission connectors 424, which can effectively improve the driving efficiency of the drive assembly 40. At the same time, the combination of multiple sets of first bevel gears 422 and second bevel gears 423 can also facilitate the direction of the driving force, thus making it easier for the drive assembly 40 to drive the heat sinks 20.

[0072] In this embodiment, the heat sink 20 includes a connector 22, a transition portion 23, and a heat dissipation body 24. Both ends of the transition portion 23 are connected to the connector 22 and the heat dissipation body 24, respectively. Along the extension direction from the connector 22 to the heat dissipation body 24, the flow cross-sectional area of ​​the transition portion 23 gradually decreases. The transmission connector 424 includes a connecting rod 4241 and a connecting piece 4242. One end of the connecting rod 4241 forms one end of the transmission connector 424, and the connecting piece 4242 forms the other end of the transmission structure 42. The connecting piece 4242 is disposed within the heat sink 20, and both ends of the connecting piece 4242 overlap the inner wall of the transition portion 23. A connecting hole 42421 is provided on the connecting piece 4242, and the other end of the connecting rod 4241 is inserted into the connecting hole 42421 to drive the connecting piece 4242 to rotate. With this configuration, the gradually decreasing flow cross-section of the transition section 23 can create a certain flow guiding effect for the heat exchange medium. In addition, the flow cross-section of the transition section 23 can also provide space for the installation of the connecting piece 4242, thereby making the connection between the connecting piece 4242 and the heat sink 20 more stable. Furthermore, the connecting hole 42421 of the connecting piece 4242 is also easier to connect with the connecting rod 4241, thus facilitating the connection between the transmission connector 424 and the heat sink 20.

[0073] Specifically, the inner wall of the transition section 23 includes a first side wall 231 and a second side wall 232, and the transition outlet 233 of the transition section 23 is located between the first side wall 231 and the second side wall 232.

[0074] The two ends of the connecting piece 4242 can respectively overlap the first sidewall 231 and the second sidewall 232. This arrangement makes the installation of the connecting piece 4242 more stable.

[0075] Alternatively, the connecting hole 42421 can be positioned opposite to the transition outlet 233. This arrangement ensures that the axes of the connecting hole 42421 and the transition outlet 233 are as coincident as possible, preventing the heat sink 20 from shifting during rotation and thus improving the stability of the heat sink 20 during rotation.

[0076] Alternatively, the two ends of the connecting piece 4242 can be overlapped on the first sidewall 231 and the second sidewall 232 respectively, while the connecting hole 42421 is positioned opposite to the transition outlet 233. This arrangement can maximize the stability of the drive assembly 40 driving the heat sink 20.

[0077] In this embodiment, the oil heater also includes a mounting housing 50, which is installed on the side of the first communicating housing 11 away from the heat sink 20. The mounting housing 50 is used to form a mounting cavity. The oil heater also includes a mounting bracket 60, which is installed in the mounting cavity. The mounting bracket 60 includes a base 61 and a support 62 connected to each other. The support 62 protrudes from the base 61 and has a support hole. The transmission rod 421 passes through the support hole.

[0078] The oil heater may also include a first bearing, which is disposed within a support hole and located between the bracket 62 and the transmission rod 421. This arrangement improves the stability of the transmission rod 421 during rotation.

[0079] Alternatively, the base 61 may be provided with multiple clearance holes, each corresponding to a different transmission connector 424, with each connector 424 passing through one of the clearance holes. The oil heater also includes a second bearing, which is disposed within the clearance holes and located between the base 61 and the transmission connector 424. This arrangement facilitates the passage of the transmission connector 424 through the base 61, and the second bearing also enhances the stability of the transmission connector 424 during rotation.

[0080] Alternatively, both the first and second bearings can be installed simultaneously, which can further enhance the stability of the drive assembly 40 during operation.

[0081] Specifically, the oil heater also includes a temperature sensing element 70 and a control element. The temperature sensing element 70 is used to detect the ambient temperature. Both the drive structure 41 and the temperature sensing element 70 are connected to the control element, so that the control element controls the drive structure 41 according to the temperature detected by the temperature sensing element 70. With this configuration, the control element can easily obtain the ambient temperature and rotate the drive structure 41 according to the real-time ambient temperature to change the setting angle of the heat sink 20, thereby changing the heat dissipation area and heat dissipation of the heat sink 20 according to actual needs.

[0082] It should be noted that the ambient temperature can be the temperature of the current location of the oil heater. When the oil heater is indoors, the ambient temperature is the temperature of the room where the oil heater is located.

[0083] In this embodiment, the oil heater also includes a connecting shell 80, which is spaced apart from the heat sink 20. The first connecting shell 11 and the second connecting shell 12 are both connected to the connecting shell 80. The temperature sensing element 70 is disposed on the side of the connecting shell 80 away from the heat sink 20. This arrangement provides installation space for the temperature sensing element 70 through the connecting shell 80, and because the temperature sensing element 70 is disposed on the side of the connecting shell 80 away from the heat sink 20, the heat dissipated by the heat sink 20 can be effectively prevented from affecting the temperature detection of the temperature sensing element 70.

[0084] In this embodiment, the heat sink 20 and the oil reservoir (corresponding to the first connecting shell 11 and the second connecting shell 12) are mechanically connected by a rotary joint (corresponding to the connecting structure 30), and the circumferential welding is eliminated, thereby enabling the heat sink 20 to rotate freely. The rotary joint has internal and external rotating threaded structures at both ends, and internally consists of a bearing structure 33, an oil retaining ring 35, and a sealing structure 34, etc., which tightly connect the heat sink 20 and the oil reservoir to achieve oil circulation.

[0085] In this embodiment, the heat sink 20 can be configured as seven pieces. Each piece's neck (corresponding to the transition portion 23) is spot-welded to a connecting piece 4242. The connecting piece 4242 has a waist-shaped hole punched in the middle. A vertical driven shaft passes through the connecting piece 4242, enabling torsional adjustment of the heat sink 20. The vertical connecting rod 4241 is a gear shaft. Its lower end connects to the connecting piece 4242 with the waist-shaped hole structure 42421, and its upper end is a bevel gear, meshing with the horizontal bevel gears one-to-one. The horizontal drive shaft (corresponding to the transmission rod 421) rotates forward or backward under the action of the motor, and the seven bevel gear sets operate synchronously, driving the driven shaft (corresponding to the connecting rod 4241) to rotate. The connecting rod 4241 engages with the connecting piece 4242 through the waist-shaped hole, thereby controlling the rotation of the heat sink 20. Under the action of the temperature detection element 70, the motor responds to the transmitted signal, the drive shaft and gear start to run, and drive the bevel gear on the longitudinal driven shaft to move. Under the torque of the driven shaft, the heat sink 20 rotates clockwise or counterclockwise by a certain angle to adjust the heat dissipation area.

[0086] like Figure 8 As shown, in Embodiment 2 of the present invention, a control method is provided. The control method is applicable to the oil heater in Embodiment 1. The control method includes: acquiring the ambient temperature T, comparing the ambient temperature with a preset temperature T0 to obtain a comparison result between the ambient temperature and the preset temperature; and controlling the rotation of the heat sink 20 of the oil heater according to the comparison between the ambient temperature T and the preset temperature T0.

[0087] With this setting, the heat sink 20 can be rotated automatically according to the ambient temperature of the oil heater, and the temperature can be automatically controlled without user intervention.

[0088] In this embodiment, the method for controlling the rotation of the heat sink 20 of the oil heater based on a comparison between the ambient temperature and a preset temperature includes: when the ambient temperature is greater than the preset temperature and T-T0 > 2℃, controlling the heat sink 20 to rotate along a first preset direction to reduce the heat dissipation area of ​​the heat sink 20; when the ambient temperature is less than the preset temperature and T0-T < 2℃, controlling the heat sink 20 to rotate along a second preset direction to increase the heat dissipation area of ​​the heat sink 20; and when -2℃ ≤ T-T0 ≤ 2℃, controlling the heat sink 20 to maintain its current angle. By using this setting, by comparing the ambient temperature with the preset temperature and determining the appropriate action to be taken for the heat sink 20 based on the comparison result, the heat dissipation area of ​​the heat sink 20 can be automatically reduced when the temperature is high and automatically increased when the temperature is low, thereby achieving an automatic constant temperature effect.

[0089] In this embodiment, the oil heater is first set to a heating temperature before use, and then it begins operation. The temperature sensor 70 identifies and determines the ambient temperature. For example, when the ambient temperature is lower than the set temperature (the set temperature tolerance is ±2℃), the temperature sensor 70 sends a heating signal. The motor responds to the transmitted signal and begins to operate (the motor rotates counterclockwise during heating and clockwise during cooling), driving the longitudinal first bevel gear 422. Under the torque of the gear shaft, the heat sink 20 rotates clockwise by a certain angle, increasing the heat dissipation area and gradually raising the room temperature. When the room temperature is higher than the set heating temperature, the temperature sensor 70 identifies and determines the temperature difference, sending a cooling signal. The motor responds and begins to rotate clockwise, while the longitudinal gear shaft drives the heat sink 20 to rotate counterclockwise, reducing the heat dissipation area and gradually lowering the room temperature until the set temperature is reached and maintained at a constant temperature.

[0090] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: by providing a rotatable heat sink 20 between the first connecting shell 11 and the second connecting shell 12, and by changing the heat dissipation area through the rotation of the heat sink 20, the heating effect of the oil heater can be controlled more flexibly, thus solving the technical problem that the heating temperature of the oil heater in the prior art is relatively fixed.

[0091] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0093] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description.

[0094] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
