Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to an oil-filled radiator heater. Background Technology

[0002] Oil-filled radiators typically consist of a main body and a heat dissipation assembly composed of multiple heat dissipation fins. The heat dissipation assembly contains an upper oil chamber, a lower oil chamber, and an oil passage, through which heat-conducting oil flows. An electric heating element is installed in the lower oil chamber. When powered on, the electric heating element heats the heat-conducting oil, which then transfers the heat to the heat dissipation fins, and subsequently to the external environment.

[0003] In oil-filled radiators, the heat-conducting oil is mainly distributed in the lower oil chamber and oil passages, with relatively less in the upper oil chamber. When the electric heating element heats the oil in the lower chamber, the heat is transferred upwards and boils at the surface of the oil in the upper chamber. This causes more hot air bubbles to rise, resulting in the upper oil chamber and its adjacent areas being hotter than the lower chamber and its adjacent areas. Therefore, a temperature limiter is typically installed in the radiator to suppress the heating power of the electric heating element and limit the ambient temperature threshold. The heating element stops operating when the ambient temperature reaches the set temperature, ensuring that the temperature rise rate of the heat sink's outer edge does not become too high and poses a risk of burns to the user, thus meeting safety regulations. This makes it difficult for oil-filled radiators to operate at full power. Furthermore, even with the heating element's power suppressed, it is still difficult to completely prevent the outer edge of the heat sink from becoming too hot and causing burns. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, an oil-filled radiator is provided, which can effectively reduce the temperature rise at the edge of the radiator and prevent burns caused by excessively high temperature at the edge of the radiator. Therefore, it is not necessary to install a temperature limiter in the body of the oil-filled radiator to suppress the temperature rise and meet safety requirements. This allows the product to work at full power and improve thermal efficiency, thereby overcoming at least one of the above-mentioned technical defects.

[0005] The specific technical solution is as follows:

[0006] An oil-filled radiator includes a main body and a heat dissipation component installed in the main body. The heat dissipation component is composed of a combination of multiple heat dissipation fins arranged in an array and forms an upper oil cavity and a lower oil cavity distributed vertically, as well as multiple oil passages connecting the upper oil cavity and the lower oil cavity vertically.

[0007] Each heat sink has multiple heat dissipation holes through its edges on both sides, and these holes extend into long strips along the length of the heat sink and are arranged in a longitudinal array.

[0008] Preferably, the outer ring of the heat sink is bent into a ring-shaped skirt.

[0009] Preferably, the edge of the annular skirt is further folded into an annular rolled edge in the direction of the main body of the heat sink.

[0010] Preferably, a side plate is welded to one side of each heat sink, and the heat sink and the side plate together form an upper oil cavity, a lower oil cavity, and an oil passage.

[0011] Preferably, the oil passage includes a main oil passage located in the middle and branch oil passages distributed on both sides of the main oil passage, and the lateral spacing of the main oil passage gradually increases from bottom to top.

[0012] Preferably, a heating tube is installed in the body, and the tube portion of the heating tube extends into the lower oil chamber.

[0013] Preferably, the heat sinks are arranged in a back-to-back direction and welded together in sequence.

[0014] The beneficial effects of the above technical solution are as follows:

[0015] (1) The oil-filled radiator includes a main body and a heat dissipation component. The heat dissipation component includes multiple heat dissipation fins and forms an upper oil chamber, a lower oil chamber, and an oil passage. Multiple elongated heat dissipation holes are also arranged in an extended direction at the edge of the heat dissipation fins, which can effectively reduce the temperature rise at the edge of the heat dissipation fins and prevent the problem of burns caused by excessively high temperature at the edge of the heat dissipation fins. Therefore, it is not necessary to install a temperature limiter in the main body of the oil-filled radiator to suppress the temperature rise and meet the safety requirements, so that the product can work at full power to improve thermal efficiency and better heating effect.

[0016] (2) The main oil circuit is designed with a narrow top and wide bottom structure, which enables the internal heat transfer oil to quickly shorten the heating time and improve the heating efficiency. At the same time, the outer ring of the heat sink is folded multiple times to form a ring skirt and a ring rolled edge structure, which can increase the heat dissipation area of ​​the heat sink and effectively improve the heat dissipation speed of the heat sink, thereby improving the heat dissipation efficiency of the electric oil heater.

[0024] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 2 The up-down direction shown on the paper is the up-down direction in this design; the left-to-right direction shown in the diagram is the front-to-back direction in this design; and the direction perpendicular to the paper and inwards shown in the diagram is the right-to-left direction in this design.

[0025] See Figures 1 to 5 As shown in the figure, the oil-filled radiator provided in this embodiment includes a main body 1 and a heat dissipation assembly 2 installed in the main body 1. The heat dissipation assembly 2 is composed of a combination of multiple heat dissipation fins 3 arranged in an array, and forms an upper oil cavity 4 and a lower oil cavity 5 distributed vertically, as well as multiple oil passages 6 connecting the upper oil cavity 4 and the lower oil cavity 5 vertically; wherein,

[0026] Each heat sink 3 has multiple heat dissipation holes 9 through its edges on both sides, and the heat dissipation holes 9 extend into long strips along the length of the heat sink 3 and are arranged in a longitudinal array.

[0027] Based on the above technical solution, the oil-filled radiator includes a main body 1 and a heat dissipation component 2. The heat dissipation component 2 includes multiple heat dissipation fins 3 and forms an upper oil cavity 4, a lower oil cavity 5, and an oil passage 6. Multiple elongated heat dissipation holes 9 are also arranged in an extended direction at the edge of the heat dissipation fins 3, which can effectively reduce the temperature rise at the edge of the heat dissipation fins 3 and prevent the problem of burns caused by excessively high temperature at the edge of the heat dissipation fins 3. Therefore, it is not necessary to install a temperature limiter in the main body 1 of the oil-filled radiator to suppress the temperature rise and meet the safety requirements, so that the product can work at full power to improve thermal efficiency and heating effect.

[0028] In a preferred embodiment, specifically as follows: Figure 3 , Figure 4 as well as Figure 7 As shown, the outer ring of the heat sink 3 is bent into an annular skirt 12. Furthermore, the edge of the annular skirt 12 is further folded into an annular rolled edge 13 in the direction of the main body of the heat sink 3, which can increase the heat dissipation area of ​​the heat sink 3, effectively improve the heat dissipation speed of the heat sink 3, and thus improve the heat dissipation efficiency of the oil-filled radiator.

[0029] As a further preferred embodiment, a side plate 8 is welded to one side of each heat sink 3, and the heat sink 3 and the side plate 8 together form an upper oil cavity 4, a lower oil cavity 5, and an oil passage 6. Furthermore, the oil passage 6 includes a main oil passage 10 located in the middle and branch oil passages 11 distributed on both sides of the main oil passage 10, and the lateral spacing of the main oil passages 10 gradually increases from bottom to top.

[0030] In practical applications, when the temperature is transferred from the lower oil chamber 5 to the upper oil chamber 4 through the oil passage 6, the oil passage 6 in this scheme has a structure that is narrow at the top and wide at the bottom, which makes the heat transfer efficiency of the lower oil chamber 5 and its adjacent area greater than that of the upper oil chamber 4 and its adjacent area. This can cause the internal heat transfer oil to quickly shorten the heating time, improve the heating efficiency, and narrow the temperature difference between the upper and lower parts.

[0031] In a preferred embodiment, a heating element 7 is installed in the body 1 of the oil-filled radiator, with the tube of the heating element 7 extending into the lower oil chamber 5. Furthermore, heat-conducting oil flows through the lower oil chamber 5, the upper oil chamber 4, and the oil passage 6. Further, the heat dissipation fins 3 are arranged in a back-to-back direction and sequentially welded together. In addition, the body 1 also includes a circuit board and a control panel or control buttons for controlling the operating state of the heating element. The heating element is an electric heating element, which is conventional technology in the art, and therefore will not be described in detail here.

[0032] Based on the above, in this solution, multiple elongated heat dissipation holes 9 are longitudinally arrayed on the left and right sides of each heat sink 3 to solve the problem of burns caused by excessively high edge temperature of the heat sink 3. The main oil passage 10 is designed with a structure that is narrow at the top and wide at the bottom, which enables the internal heat-conducting oil to quickly shorten the heating time and improve the heating efficiency. At the same time, the outer ring of the heat sink 3 is folded multiple times to form a structure of annular skirt 12 and annular rolled edge 13, which can increase the heat dissipation area of ​​the heat sink 3 and effectively improve the heat dissipation speed of the heat sink 3, thereby improving the heat dissipation efficiency of the electric oil heater. Therefore, there is no need to set a temperature limiter in the body 1 of the oil heater, so that it can work at full power to provide heating power and efficiency, and meet safety requirements.

[0033] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
