Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to an electric oil heater and heating device. Background Technology

[0002] An electric oil-filled radiator is a heating device that uses an electric heating element to heat thermal oil. Heat is released through the convection and radiation of the oil, raising the indoor temperature. It is primarily used in enclosed or semi-enclosed indoor spaces such as bedrooms, living rooms, and offices, and is especially suitable for the elderly, children, and those sensitive to airflow. Compared to other heating devices such as air conditioners and fan heaters, electric oil-filled radiators offer significant advantages: no fan operates during heating, ensuring completely silent operation and avoiding noise interference; heat dissipation relies on the surface of the oil-filled radiator, eliminating strong airflow and preventing dryness or dust accumulation, thus maintaining a comfortable environment; and the thermal oil has excellent heat storage properties, continuing to release heat even after power is off, providing stable and long-lasting heating.

[0003] However, the existing design of oil-filled electric radiators has significant limitations: the overall structure is fixed and unchanging, mostly in the form of rectangular columns or plates, and cannot be adjusted to meet different usage needs. This fixed shape limits the heating space, covering only a certain area around the device, making it difficult to adapt to rooms of different sizes. Furthermore, the lack of shape flexibility means the device occupies a fixed space during use, which can easily cause cramped conditions in small apartments or temporary heating scenarios, and its inability to flexibly adapt to different placement environments restricts its application in more scenarios.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Reference Figures 1 to 7d As shown, it illustrates an embodiment of the electric oil-filled radiator and heating device of this utility model. The electric oil-filled radiator includes multiple heat dissipation components 1 and multiple rotating components 2, the multiple heat dissipation components 1 being spaced apart; each of the rotating components 2 is located between two adjacent heat dissipation components 1, and both sides of the rotating component 2 are rotatably connected to the two heat dissipation components 1 respectively, and the internal space of each rotating component 2 is in communication with the internal space of the two adjacent heat dissipation components 1.

[0031] Specifically, the oil-filled radiator is a type of heating device that releases heat through the convection and radiation of heat-conducting oil to raise the indoor temperature. However, the shape of current oil-filled radiators is fixed, and their heat sinks 11 are generally vertical, making it impossible to rotate them to adapt to various environmental needs, which reduces the applicability of the oil-filled radiator.

[0032] Therefore, this utility model provides an electric oil heater whose main body can rotate, thereby enabling the electric oil heater to have multiple forms to suit various environmental needs.

[0033] The electric oil heater includes multiple heat dissipation components 1 and multiple rotating components 2. The heat dissipation components 1 are used to release the heat generated inside the electric oil heater to dissipate the heat to the indoor environment, thereby increasing the indoor temperature. The heat dissipation component 1 is the oil body of the electric oil heater, and the internal space of the heat dissipation component 1 is hollow, that is, the inside of the heat dissipation component 1 is filled with heat-conducting oil, thereby making the heat dissipation efficiency of the heat dissipation component 1 higher. The electric oil heater includes multiple heat dissipation components 1, thereby increasing the heat dissipation range of the electric oil heater and generating more heat. The multiple heat dissipation components 1 are arranged at intervals, and the internal spaces of the multiple heat dissipation components 1 are connected, so that the heat-conducting oil in the internal space of the multiple heat dissipation components 1 can flow in the oil heater body, thereby forming heat convection and heat radiation, and then releasing heat through the shell of the heat dissipation component 1.

[0034] The plurality of rotating components 2 are spaced apart, and each rotating component 2 is located between two adjacent heat dissipation components 1. The two sides of each rotating component 2 are rotatably connected to the two heat dissipation components 1, that is, each rotating component 2 is rotatably connected to the heat dissipation components 1 on both sides. The rotating component 2 is used to rotatably connect two adjacent heat dissipation components 1 so that each heat dissipation component 1 can rotate freely, thereby realizing the rotation function of the electric oil heater. That is, the user can rotate each heat dissipation component 1 according to actual needs, thereby adjusting the shape of the electric oil heater to adapt to different scenario needs and improving the applicability of the electric oil heater.

[0035] Meanwhile, to ensure that the internal spaces of the multiple heat dissipation components 1 are connected, thereby ensuring that the heat transfer oil flows within the multiple heat dissipation components 1 to generate heat convection and heat radiation, the internal space of each of the rotating components 2 and the internal spaces of the two adjacent heat dissipation components 1 are all set to be connected. That is, the internal space of the oil radiator body composed of the multiple heat dissipation components 1 and the multiple rotating components 2 is connected. The internal space of the oil radiator body is filled with heat transfer oil so that the heat transfer oil can flow within the internal spaces of the multiple heat dissipation components 1 and the multiple rotating components 2 to generate heat convection and heat radiation, thereby generating heat to increase the indoor ambient temperature.

[0036] Therefore, this application rotatably connects the rotating component 2 between two adjacent heat dissipation components 1, allowing each heat dissipation component 1 to rotate freely. The oil heater has a rotation function, and the user can rotate each heat dissipation component 1 to a specified position according to the actual usage scenario, thereby freely adjusting the shape of the oil heater and improving its applicability, making it suitable for various usage environments.

[0037] In one embodiment, reference is made to Figures 1 to 2 , Figure 5 As shown, the rotating component 2 includes a first rotating member 21 and a second rotating member 22, which are rotatably connected. The side of the first rotating member 21 away from the second rotating member 22 is connected to the adjacent heat dissipation component 1, and the side of the second rotating member 22 away from the first rotating member 21 is connected to the adjacent heat dissipation component 1.

[0038] Specifically, the two sides of the rotating component 2 are respectively rotatably connected to two adjacent heat dissipation components 1, that is, the rotation of the two adjacent heat dissipation components 1 is independent and does not interfere with each other. Therefore, the rotating component 2 includes a first rotating member 21 and a second rotating member 22, which are rotatably connected. The first rotating member 21 is used to rotatably connect one of the heat dissipation components 1, and the second rotating member 22 is used to rotatably connect the other heat dissipation component 1, so that the two adjacent heat dissipation components 1 can rotate independently, allowing the user to rotate each heat dissipation component 1 to a different position.

[0039] In this design, the side of the first rotating member 21 away from the second rotating member 22 is connected to an adjacent heat dissipation component 1, and the side of the second rotating member 22 away from the first rotating member 21 is connected to another adjacent heat dissipation component 1. Therefore, when the user rotates the heat dissipation component 1 connected to the first rotating member 21, the heat dissipation component 1 can rotate relative to the other heat dissipation component 1; when the user rotates the other heat dissipation component 1 connected to the second rotating member 22, the other heat dissipation component 1 can rotate relative to the heat dissipation component 1 connected to the first rotating member 21. This makes the rotation of the two adjacent heat dissipation components 1 independent of each other, and the user can freely adjust the rotation position of each heat dissipation component 1 to make the shape of the electric oil heater more varied and its applicability higher.

[0040] In a specific embodiment, refer to Figures 1 to 2 , Figure 5 As shown, the rotating assembly 2 further includes a rotating shaft 23, which is located between the first rotating component 21 and the second rotating component 22. Both sides of the rotating shaft 23 are rotatably connected to the first rotating component 21 and the second rotating component 22, respectively. Specifically, the rotating assembly 2 further includes a rotating shaft 23, which is used to rotatably connect the first rotating component 21 and the second rotating component 22. The rotating shaft 23 is located between the first rotating component 21 and the second rotating component 22, meaning that both sides of the rotating shaft 23 are rotatably connected to the first rotating component 21 and the second rotating component 22, thereby allowing the first rotating component 21 and the second rotating component 22 to rotate independently without interfering with each other. This, in turn, allows two adjacent heat dissipation assemblies 1 to rotate independently and be adjusted to different positions. The rotating assembly 2 has a simple structure and high structural stability.

[0041] In one embodiment, the first rotating member 21 and the adjacent heat dissipation assembly 1 are connected by a welded seal; and / or, the second rotating member 22 and another adjacent heat dissipation assembly 1 are connected by a welded seal. Specifically, the first rotating member 21 and the second rotating member 22 are respectively fixedly connected to the heat dissipation assembly 1 by a welded seal, so that the connection between the first rotating member 21 and the second rotating member 22 and the heat dissipation assembly 1 is simple, quick to install and low in cost. At the same time, this fixing method has high stability and can effectively prevent the first rotating member 21 and the second rotating member 22 from detaching from the heat dissipation assembly 1.

[0042] In one embodiment, reference is made to Figure 6As shown, the rotating component 2 has through holes 24 penetrating both sides, which connect the internal spaces of two adjacent heat dissipation components 1. Specifically, two heat dissipation components 1 are rotatably connected to each side of the rotating component 2. To ensure that the internal spaces of all heat dissipation components 1 are connected, the internal spaces of the rotating component 2 need to be connected, thereby connecting two adjacent heat dissipation components 1. Therefore, the rotating component 2 has through holes 24 penetrating both sides, connecting the internal spaces of two adjacent heat dissipation components 1. That is, the internal spaces of multiple heat dissipation components 1 and multiple rotating components 2 are connected, so that the heat-conducting oil in the internal spaces of multiple heat dissipation components 1 and multiple rotating components 2 can flow, generating heat convection and heat radiation, thereby improving the working efficiency of the electric oil heater.

[0043] In a specific embodiment, refer to Figure 3 As shown, the rotating component 2 is a sealed structure. Specifically, to ensure that the heat transfer oil can flow within the internal spaces of the multiple heat dissipation components 1 and the multiple rotating components 2, the rotating component 2 is configured as a sealed structure, that is, the rotating component 2 is made of a sealing material, and the exterior of the rotating component 2 is sealed, communicating only with the internal spaces of the two adjacent heat dissipation components 1 through the through hole 24. This prevents the heat transfer oil from leaking from the rotating component 2 to the outside, improves the structural stability of the electric oil heater, and avoids oil leakage.

[0044] In one embodiment, reference is made to Figures 1 to 3 As shown, the heat dissipation assembly 1 includes a heat sink 11 and an oil reservoir 12 with interconnected internal spaces. The oil reservoir 12 is fixed to the bottom end of the heat sink 11 and is rotatably connected to the rotating assembly 2 with interconnected internal spaces.

[0045] Specifically, the heat dissipation component 1 includes heat sinks 11 and an oil reservoir 12. The heat sinks 11 are used to increase the heat dissipation area of ​​the electric oil heater and efficiently transfer heat to the air. The heat sinks 11 are usually made of a metal with good thermal conductivity (such as steel or aluminum alloy), and are vertically arranged with a wavy or sheet-like structure with cavities. Multiple heat sinks 11 are arranged closely together to form an integral radiator. The oil reservoir 12 is used to store and circulate heat transfer oil as a heat storage medium and a heat transfer medium. The oil reservoir 12 is generally located at the top and bottom of the heat sinks 11. In this embodiment, the oil reservoir 12 refers to the oil reservoir 12 located at the bottom of the heat sinks 11. The internal space of the oil reservoir 12 and the internal space of the heat sink 11 are in a connected state, that is, the heat transfer oil can flow in the internal space of the oil reservoir 12 and the heat sink 11, thereby generating heat convection and heat radiation. The oil pack 12 and the heat-conducting oil are used to absorb and store the heat from the heating element, and to evenly distribute the heat to all corners of the heat sink 11 through circulation. The heat sink 11 utilizes its large surface area to efficiently and gently dissipate the heat received from the heat-conducting oil into the air, warming the indoor environment.

[0046] In this embodiment, refer to Figures 7a to 7d As shown, the oil pack 12 and the rotating assembly 2 are rotatably connected, so that each heat sink 11 can rotate 90° to the left or 90° to the right individually, forming different states; and the internal space of the oil pack 12 and the internal space of the rotating assembly 2 are horizontally connected, that is, the rotating assembly 2 is rotatably connected to one side of the oil pack 12, and the internal spaces of the two are interconnected, so that the internal space of each oil pack 12 is interconnected, so that the heat transfer oil can flow between each oil pack 12 and each heat sink 11, thereby circulating and evenly transferring heat to each corner of the heat sink 11.

[0047] Therefore, in this embodiment, the rotating component 2 is rotatably connected to the oil pack 12. The contact area between the oil pack 12 and the rotating component 2 is large, thereby improving the stability of the heat dissipation component 1 during rotation. This makes the installation of the rotating component 2 simpler and more stable. At the same time, the rotating component 2 does not affect the heat dissipation efficiency of the heat sink 11.

[0048] In one embodiment, reference is made to Figures 1 to 4As shown, the internal spaces of the plurality of oil bags 12 and the plurality of rotating components 2 form a heating groove 13. The electric oil heater also includes a heating component 3, which is inserted into the heating groove 13 and rotatably connected to the heat dissipation component 1. Specifically, the electric oil heater includes a plurality of heat dissipation components 1 and a plurality of rotating components 2. The plurality of heat dissipation components 1 include a plurality of oil bags 12 and a plurality of heat sinks 11. The plurality of oil bags 12 are horizontally spaced at the bottom ends of the plurality of heat sinks 11. Each rotating component 2 is located between two adjacent oil bags 12, and the internal spaces of the plurality of oil bags 12 and the plurality of rotating components 2 are horizontally connected.

[0049] Therefore, the multiple oil packs 12 and the multiple rotating components 2 are horizontally rotatably connected, and their internal spaces are horizontally interconnected, thereby forming a heating tank 13. The heating tank 13 is used to accommodate the heating component 3 of the electric oil heater. The heating tank 13 is filled with heat-conducting oil so that the heating component 3 can heat the heat-conducting oil in the heating tank 13. This allows the heat-conducting oil to circulate heat to every corner of the heat sink 11, thereby improving the heat dissipation efficiency and heat dissipation area of ​​the electric oil heater.

[0050] The electric oil heater also includes a heating component 3, which is used to heat the heat transfer oil. The heating component 3 has a slot in the heating groove 13 into which it is inserted. The heating component 3 is rotatably connected to the heat dissipation component 1. Therefore, when the heat dissipation component 1 rotates, it does not affect the state of the heating component 3, thereby improving the structural stability of the electric oil heater and ensuring the free rotation of the heat dissipation component 1.

[0051] More specifically, one end of the heating component 3 is rotatably connected to the heat dissipation component 1 located at the end, and the heating component 3 and the heating groove 13 are in a clearance fit. That is, the heat dissipation component 1 and the rotating component 2 surrounding the heating component 3 and the heating groove 13 are not in contact, so as not to affect the rotation operation of the heat dissipation component 1 and the rotating component 2, so that the heating component 3 is fixed in the heating groove 13, so as to better heat the heat transfer oil and improve the structural stability of the electric oil heater.

[0052] In a specific embodiment, refer to Figures 1 to 4As shown, the heating assembly 3 includes a heating tube 31 and a heating element 32. The heating element 32 is fixed inside the heating tube 31, and the heating tube 31 extends along the length of the heating groove 13. Specifically, the heating assembly 3 is mainly used to heat the heat transfer oil. Therefore, the heating assembly 3 includes a heating tube 31 and a heating element 32. The heating tube 31 is used to increase the heating area of ​​the heating assembly 3 on the heat transfer oil, and the heating element 32 is used to generate heat. The heating element 32 is fixedly installed inside the heating tube 31, so that the heat generated by the heating element 32 can be transferred from the inside to the outside to the heating tube 31, thereby increasing the heating area of ​​the heating assembly 3. The heating tube 31 extends along the length of the heating groove 13, and the heating tube 31 is located inside the heating groove 13, that is, the heating tube 31 is in direct contact with the heat transfer oil, so that the heating tube 31 can directly heat the heat transfer oil to improve heating efficiency, thereby improving the working efficiency of the electric oil heater.

[0053] More specifically, refer to Figures 1 to 3 As shown, the heating assembly 3 also includes a mounting part rotatably connected to a heat dissipation assembly 1 located at the end. The mounting part is fixedly connected to one end of the heating tube 31, and one end of the heating element 32 is fixedly connected to the mounting part. The other end of the heating element 32 extends along the length direction of the heating tube 31.

[0054] Therefore, the heating component 3 is rotatably connected to a heat dissipation component 1 located at the end via the mounting part, allowing the heat dissipation component 1 to rotate freely. The mounting part is fixed to one end of the heating tube 31, allowing the heating tube 31 to be inserted into the heating groove 13. The mounting part is located at the opening of the heating groove 13 and seals the heating groove 13, preventing the heat transfer oil from leaking from the opening of the heating groove 13. At the same time, the heating component 3 has high structural stability. Furthermore, one end of the heating element 32 is fixedly connected to the inner wall of the mounting part, and the other end of the heating element 32 extends along the length of the heating tube 31, allowing the heat generated by the heating element 32 to be transferred to various positions of the heating tube 31, ensuring the heating effect of the heating tube 31 on the heat transfer oil and improving the heating efficiency of the heating component 3.

[0055] More specifically, the mounting part and the heat dissipation assembly 1 are rotatably connected by a threaded fastening and sealing method, which is simple and low in cost.

[0056] In one embodiment, reference is made to Figures 1 to 2 , Figure 4As shown, the heating tube 31 is provided with a plurality of oil passage holes 311. The plurality of oil passage holes 311 are spaced apart and uniformly arranged along the circumference and radial direction of the heating tube 31. The oil passage holes 311 connect the heating groove 13 and the heating element 32.

[0057] Specifically, the heating tube 31 is provided with multiple oil passage holes 311, which penetrate the inner and outer sides of the heating tube 31. That is, the oil passage holes 311 connect the heating tank 13 and the heating element 32, allowing heat transfer oil to flow from the heating tank 13 through the oil passage holes 311 into the internal space of the heating tube 31. This facilitates the flow of heat transfer oil, ensuring that both the inner and outer sides of the entire heating tube 31 are immersed in heat transfer oil, further improving the heating efficiency of the heat transfer oil by the heating tube 31. Simultaneously, it allows the heat transfer oil to directly contact the heating element 32, enabling the heating element 32 to directly heat the heat transfer oil, further improving the heating efficiency of the heat transfer oil and avoiding energy waste. Furthermore, the multiple oil passage holes 311 are evenly spaced along the circumference and radial direction of the heating tube 31, thereby increasing the flow rate of heat transfer oil into the interior of the heating tube 31, further improving the heating efficiency of the heat transfer oil by the heating element 32.

[0058] This embodiment also provides a heating device (not shown in the figure), which includes an electric oil heater. The electric oil heater can be any type of electric oil heater provided by this utility model. Since the specific structure and working principle of the electric oil heater have been described in detail in the previous specification, they will not be repeated here for the sake of brevity.

[0059] The heating device in this embodiment uses the electric oil heater provided by this utility model. Each heat dissipation component 1 of the electric oil heater can realize an independent rotation function. The electric oil heater has multiple usage forms, so the heating device has different usage forms and can be applied to different spatial locations, thus improving the applicability of the heating device.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
