Example 1
The utility model provides an electric oil-filled radiator, as shown in figure 1, include: the electric heating device comprises a plurality of electric heating piece pieces 1, a heating part and a heating part, wherein the electric heating piece 1 comprises an upper oil pocket 11 and a lower oil pocket 12 which are arranged on the electric heating piece 1, and a heating part 13 is arranged in the lower oil pocket 12; the oil-way passages 5 are distributed on the heater sheet 1 and are used for communicating the upper oil pocket 11 with the lower oil pocket 12, the number of the oil-way passages 5 is different, and the number of the oil-way passages 5 corresponding to the part close to the upper oil pocket 11 in the height direction is relatively small; and/or in the height direction of the heater sheet 1, the distance M between the oil passage channel 5 close to the edge 2 of the heater sheet 1 and the edge 2 is different, and the M corresponding to the oil passage channel 5 close to the oil feeding pocket 11 is relatively larger. When the electric oil heater works, the heat conducting oil is distributed in the lower oil pocket 12 and the oil path channel 5, and a small amount of heat conducting oil is arranged in the upper oil pocket 11 or the liquid level of the heat conducting oil does not enter the upper oil pocket 11. When the heating part 13 in the lower oil pocket 12 heats, the heat conducting oil in the lower oil pocket 12 is heated, the heat conducting oil transfers the heat to the oil path channel 5, and the liquid level of the heat conducting oil in the upper oil pocket 11 is boiled. During boiling, more hot bubbles move from bottom to top into the oil pocket 11. Therefore, heat is transferred to the whole range of the radiator sheet 1 through the oil feeding pocket 11 and the oil passage 5. When the value of M is increased, namely the distance between the oil path channel 5 close to the edge 2 and the edge 2 is increased, the heat transfer distance from the oil path channel 5 to the edge 2 is increased, the heat transfer efficiency to the edge 2 is reduced, and the temperature rise of the edge 2 is reduced, so that the temperature of the edge 2 is reduced in use. When the number of the oil channels 5 is reduced, the heat transferred from the oil channels 5 to the heater sheet 1 in unit time under the same environment is reduced, the heat transfer efficiency is reduced, the temperature rise of the edge 2 is reduced, and the temperature of the edge 2 is reduced during use.
The distribution structure of the oil channels 5 is not particularly limited, in this embodiment, as shown in fig. 2, the oil channels 5 sequentially form at least a first part 3 and a second part 4 of the heater sheet 1 along the direction from the upper oil pocket 11 to the lower oil pocket 12. When the heater sheet 1 works, the temperature of the part of the heater sheet 1 close to the upper oil pocket 11 is relatively high because the hot bubbles move towards the upper oil pocket 11. Therefore, the oil passage 5 is divided into a first part 3 and a second part 4 from top to bottom in the present embodiment. The first part 3, which is at a relatively high temperature, can be modified in order to achieve the effect of reducing the temperature of the edge 2. As an alternative embodiment, the direction from the upper oil pocket 11 to the lower oil pocket 12 of the heater sheet 1, i.e. the direction from top to bottom in the figure, is divided into the first part 3, the second part 4 and the third part.
As shown in fig. 2 and 3, the number of the oil passages 5 corresponding to the first portion 3 is smaller than that of the second portion 4. By reducing the number of the oil-way channels 5 above, the problem of overhigh temperature rise of the edge 2 is solved, and the second part 4 is kept to be provided with more oil-way channels 5, so that the heat dissipation performance of the heater sheet 1 is kept. Namely, the temperature of the edge 2 is reduced on the premise of not influencing the heating effect.
The number of the oil passages 5 is not particularly limited, and in this embodiment, as shown in fig. 2, one oil passage 5 of the first portion 3 is provided to ensure that the oil outlet packet 12 is communicated with the oil outlet packet 11. As an alternative embodiment, the oil passage 5 of the first portion 3 is two. In this embodiment, as shown in fig. 2 and 3, the number of the oil passages 5 of the second portion 4 is three. As an alternative embodiment, the number of oil passages 5 of the second portion 4 is two or four.
In this embodiment, as shown in fig. 3, an average distance between adjacent oil passages 5 in the first portion 3 is smaller than an average distance between adjacent oil passages 5 in the second portion 4. The average distance between the adjacent oil channels 5 in the first part 3 is smaller than the average distance between the adjacent oil channels 5 in the second part 4. I.e. the oil passage 5 of the first part 3 is relatively more compact, so that the distance from the oil passage 5 near the edge 2 to the edge 2 is increased, i.e. the value of M is increased. As shown in fig. 1, when there is one oil passage 5 in the first part 3, the average distance between the oil passages 5 corresponding to the first part 3 is zero.
Wherein, in the embodiment, the lengths of the oil passage 5 in the first part 3 and the second part 4 are the same. The adjacent oil channels 5 are parallel to each other. The M value is [20mm, 60mm ].
In this embodiment, a comparative experiment is performed on the reduction of the number of oil passages and the influence of the change of the M value on the temperature rise of the edge, and the results refer to the following table:
wherein:
in the experiment process, the same temperature starting point is adopted in the experiment environment, and the environment temperature is increased to the same temperature value when the oil heater of each group of experiments is used. And (4) the temperature rise of the edge is calculated by subtracting the ambient temperature from the temperature of the edge. Namely, the edge temperature rise represents the temperature of the edge when the electric oil heater heats the environment to the same temperature. I.e. representing the temperature of the edge in the case of the same actual heating effect.
1) Compared with the scheme two, the number of oil channels is the same, the M value is increased, and the temperature rise of the seamed edge is reduced by 2K;
2) compared with the third scheme, the first scheme has the same M value, reduces the number of oil channels and reduces the temperature rise of the seamed edge by 4K;
3) compared with the scheme I, the M value is increased, the number of oil channels is reduced, and the temperature rise of the seamed edge is reduced by 10K;
4) compared with the scheme II, the scheme IV reduces the number of oil-way channels, and compared with the scheme I, the scheme I reduces two oil-way channels, but the increase of the M value is relatively less, and the temperature rise of the seamed edge is reduced by 8K.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
