Description

Technical Field

[0001] The present application relates to an electric oil heater with arc-shaped heat sinks, which is applicable to the technical field of heating equipment. Background Art

[0002] Existing electric oil heaters consist of multiple welded units. Each unit is typically formed by two interconnected heat sinks, with an interconnected oil channel between the two fins. The heat sinks are heated by the heated oil flowing through the channel. To increase the heat dissipation area, at least one heat sink in each unit is further formed with fins, which can be either straight or curved.

[0003] The Chinese patent application number 202122581690.2 discloses a heater with a heat sink, comprising a plurality of heat sink units connected in sequence, each heat sink unit being formed by connecting a first heat sink and a second heat sink, and the second heat sink of each heat sink unit is connected to the first heat sink of the adjacent unit; the end of the heat sink of each heat sink unit is continuously provided with folded edges along the circumference. The bent heat sink in this patent adopts the form of right-angle bending, and the folded edges of adjacent heat sinks are spaced far apart from each other, forming a gap between the two. During the manufacturing process, uneven gaps often occur, which affects the aesthetics of the product and results in a high defective rate of the product. In addition, right-angle bending often causes interference between the folded edges of adjacent heat sinks, resulting in a limited distance between adjacent heat sinks and an inability to increase the arrangement density of the heat sink.

[0004] On the other hand, in the existing technology, electric oil heaters with clothes drying racks generally have the clothes drying racks directly clipped onto the top of the electric oil heater body, and the clothes drying racks are usually made of plastic. However, the slow heating characteristics of electric oil heaters and the strength limitations of plastic brackets make the clothes drying efficiency of electric oil heaters low and the customer experience is poor.

[0005] Therefore, there is a need in the prior art for an electric oil heater with beautiful appearance, high yield, good clothes drying effect and the ability to increase the density of heat sinks. Utility Model Content

[0006] The purpose of this application is to design an electric oil heater with curved fins. The fins have curved curved surfaces on both sides. This not only creates a chimney effect, enhancing convection and facilitating drying of clothes, but also allows for a denser arrangement of the fins, improving drying efficiency. Furthermore, the gaps between the fins and internal oil pockets are concealed, enhancing the product's appearance and improving product yield.

[0007] The present application relates to an electric oil heater with curved heat sinks, comprising a plurality of heat sink units connected in sequence, each heat sink unit being formed by docking a first heat sink and a second heat sink, and each heat sink unit being further provided with a curved heat sink, wherein at least a portion of one of the two adjacent curved heat sinks is wrapped by the other curved heat sink; or the two adjacent curved heat sinks are arranged without a gap along the length direction of the electric oil heater.

[0008] wherein, the arc-shaped heat sink may be an extension of at least one of the first heat sink and the second heat sink, or the arc-shaped heat sink may be a separate component connected to at least one of the first heat sink and the second heat sink; a vertical channel for hot air flow may be formed between two adjacent arc-shaped heat sinks; the first heat sink and the second heat sink may be formed with protrusions in opposite directions at corresponding positions, thereby forming an oil bag for accommodating heating oil on the heat dissipation unit, and the first heat sink and the second heat sink may be formed with oil holes at the positions of the oil bags, and the oil bags of adjacent heat dissipation units may be connected through the oil holes; oil ribs may also be formed on the first heat sink and the second heat sink, respectively, The oil ribs on the first heat sink and the second heat sink can cooperate to form an oil guide cavity, and the oil guide cavity and the oil bag can be connected through a connecting part; the electric oil heater can also include an insulating bottom plate, and the insulating bottom plate is connected to the heat dissipation body of the electric oil heater through an adapter; the electric oil heater can also include a clothes drying rack, and the clothes drying rack is arranged above the electric oil heater; the clothes drying rack can include a vertical bracket, and the vertical bracket is provided with a cross bar; the electric oil heater can be provided with a mask assembly, and the mask assembly can be integrally formed with a mounting portion for fixing the vertical bracket, or the vertical bracket and the mask assembly can be integrally formed; a clothes hanger net bag can be provided between the cross bar and the electric oil heater.

[0009] The oil-filled electric heater with curved heat sinks according to the present application has the following technical advantages:

[0010] (1) The arc-shaped heat sinks of the oil heater are stacked layer by layer, similar to the shape of fish scales, which can cover the gaps between the heat sinks, improve the integrity of the oil heater body, make the product more beautiful, and reduce the poor appearance caused by uneven gaps between the heat sinks during welding, thereby improving production efficiency and yield rate;

[0011] (2) The curved heat sink can form a more closed and compact convection space, so that the heat dissipation unit can be arranged at a higher density, thereby increasing the number of heat sinks per unit length and improving the heat dissipation efficiency;

[0012] (3) When the arc-shaped heat sinks are overlapped and connected in sequence, a relatively closed space can be formed between the heat sinks. When the oil-filled radiator is heated, a chimney effect is formed, and obvious convection movement occurs in this closed space. The convection movement carries high-heat air through the clothes hanger above, which can greatly improve the drying efficiency.

[0013] (4) Fixing the legs of the clothes hanger on the main body of the heater can not only improve production efficiency, but also integrate the function of the clothes drying rack into the main body of the electric oil heater, thereby improving the versatility of the product.

[0021] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0022] According to the present application, an electric oil heater with an arc-shaped heat sink comprises a heat sink and an electric control component arranged at one end of the heat sink, wherein the electric control component is a prior art and is not shown in the drawings. Figure 1As shown, the heat sink of the present application includes a plurality of heat sink units connected in sequence, and each heat sink unit is formed by docking a first heat sink 1 and a second heat sink 2, and the second heat sink of each heat sink unit is connected to the first heat sink of the adjacent heat sink unit. The first heat sink 1 and the second heat sink 2 are respectively formed with protrusions in opposite protrusion directions at the upper and lower parts, so that oil bags 4 for containing heating oil are respectively formed at the upper and lower parts of the heat sink unit. The first heat sink 1 and the second heat sink 2 are respectively formed with oil holes at the positions of the oil bags 4 to connect the oil bags of adjacent heat sink units. The first heat sink 1 and the second heat sink 2 are also formed with oil ribs 3 arranged in the vertical direction. When the first heat sink 1 and the second heat sink 2 are docked and installed, the oil ribs 3 cooperate to form an oil guide cavity, and the oil guide cavity and the oil bag 4 are connected by a connecting part, thereby forming a channel for the circulation of heating oil.

[0023] like Figure 1-3 As shown, the electric oil heater of the present application is also provided with flared curved heat sinks 5, which are arranged on both sides of the heat sink, and are compactly arranged between two adjacent curved heat sinks. The compact arrangement described in the present application means that at least a portion of one of the curved heat sinks is wrapped by another curved heat sink, or that there is no gap between the two adjacent curved heat sinks along the length of the electric oil heater, and even a closed cavity can be formed. The gapless arrangement mentioned in the present application does not mean no gap in the absolute sense, but only means that the gap between the two adjacent curved heat sinks is very small and will not affect the vertical channel for hot air circulation formed between the two adjacent heat sinks.

[0024] Preferably, the curved heat sink may be an extension formed by a natural extension of at least one of the first heat sink 1 and the second heat sink 2. The curved heat sink may also be a separate component connected to at least one of the first heat sink 1 and the second heat sink 2. Figure 5 As shown, the present application sequentially connects the heat dissipation units with the above-mentioned heat sinks, and finally uses an adapter 6 to secure the heat insulating base sheet 7 to the heat sink, thereby forming an oil radiator body. Preferably, the heat insulating base sheet 7 is made of a heat insulating material. Since the heat insulating base sheet 7 is not connected to the heating oil channel on the heat sink, and is made of a heat insulating material, heat is not transferred to the heat insulating base sheet 7, thereby preventing burns to the human body.

[0025] like Figure 4As shown, the present application arranges the heat sink in a flared arc shape so that two adjacent heat sinks can be arranged closer together. That is, at least a portion of one heat sink can be wrapped inside the other heat sink, thereby increasing the number of heat sinks per unit length and improving heat dissipation efficiency. On the other hand, by wrapping at least a portion of one heat sink inside another heat sink, it is possible to arrange two adjacent heat sinks with no gap or a small gap. This not only improves the aesthetics of the product and reduces the defective rate, but also forms a vertical channel 14 for hot air circulation between adjacent heat sinks. This vertical channel 14 is particularly advantageous for situations where a clothes drying rack is arranged above the heater.

[0026] like Figure 6-7 As shown, the electric oil heater of the present application is provided with a mask assembly 10, a vertical bracket 11 is fixedly provided on the mask assembly 10, and a cross bar 12 is provided at the upper end of the vertical bracket 11. Preferably, a mounting portion for fixing the vertical bracket 11 can be integrally formed on the mask assembly 10, and the vertical bracket and the mounting portion can be connected in the form of plug-in connection, snap connection, or spiral connection. At least a part of the oil heater body is provided in the mask assembly 10, and the cross bar 12 is provided above the oil heater body, and clothes can be hung on the cross bar 12 to dry. Preferably, as Figure 6 As shown, the oil heater body is fixed to the right side of the mask assembly 10. The left and right hanger legs serve as vertical brackets, respectively fixed to the left and right sides of the mask assembly. The front and rear crossbars pass through the tops of the left and right hanger legs and are fixed above the oil heater body. A hanger net bag 13 can also be provided between the crossbar 12 and the oil heater body. The hanger net bag 13 can be installed on the vertical bracket 11, the oil heater body, or the mesh mask assembly.

[0027] By integrating the rack's bracket onto the oil-heating heater, this application creates a tighter connection between the rack and the oil-heating heater, more intuitively demonstrating the product's versatility and improving the speed and convenience of rack installation. Furthermore, the compact arrangement of the curved fins creates a flow channel for hot air to circulate upward and downward between the fins, enhancing the fluidity and circulation of the hot air. This allows clothes placed on the rack above the oil-heating heater to be dried more efficiently, shortening drying time and improving drying efficiency.

[0028] Although the embodiments disclosed in this application are as described above, the contents described are merely embodiments adopted to facilitate understanding of this application and are not intended to limit this application. Any person skilled in the art of the art to which this application belongs may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this application. However, the scope of patent protection of this application shall still be based on the scope defined by the attached claims.
