When the number of the oil chambers 30 is two, both ends of the main heat dissipation channel 11 are respectively communicated with one oil chamber 30, both ends of the auxiliary heat dissipation channel 13 are respectively communicated with one oil chamber 30, one end of the connection channel 15 is connected to the main heat dissipation channel 11, and the other end is connected to the auxiliary heat dissipation channel 13. When the oil chamber is set to one, one end of the main heat dissipation passage 11 communicates with the oil chamber 30, and one end of the auxiliary heat dissipation passage 13 communicates with the oil chamber 30.
The oil chamber 30 and the radiator 10 may be an integral structure or a separate assembly structure. The shape of the heat radiator 10 may take a plate shape, a column shape, or other shapes. In one embodiment, the heat sink 10 is a fin, and a plurality of fins are welded together. Cavities are formed in the upper end and the lower end of each fin, and the cavities of the fins are communicated to form the oil cavity 30.
The main heat dissipation channel 11 may be provided by opening a channel inside the heat sink 10.

Can also be fixedly connected as a whole so as to facilitate processing. The heat sink 10 may be made of a metal material, such as copper, aluminum or a metal alloy material. The body part and the radiating pipe can be made of the same material or different materials. The communication between the heat dissipation channel and the oil chamber 30 may be smooth to facilitate the circulation of the heat transfer oil.

In the technical scheme of the invention, the heat conducting oil in the oil cavity 30 enters the main heat dissipation channel 11 after being heated and then flows back from the auxiliary heat dissipation channel 13. In the process of circulation of the main heat dissipation channel 11, auxiliary circulation of the oil circuit is realized through the connecting channel 15 between the main heat dissipation channel 11 and the auxiliary heat dissipation channel 13. For example, the auxiliary circulation oil passage is: the oil chamber 30 is connected with the main heat dissipation channel 11, enters the auxiliary heat dissipation channel 13 through the connecting channel, and then flows back to the original oil chamber 30. That is, the auxiliary heat dissipation channel 13 and the connection channel 15 are arranged to increase the area of oil circuit circulation, so that the internal circulation of the heat conduction oil of the heat dissipation body 10 can be promoted, and the continuous development of the boundary layer of the air side of the heat dissipation body can be destroyed and cut off, thereby shortening the heating time, improving the heating efficiency and realizing the rapid temperature rise of the oil heater 100.
When two oil chambers are provided, the heat transfer oil in the oil chamber 30 is heated, enters the main heat dissipation channel 11, flows into another oil chamber 30, and then flows back from the auxiliary heat dissipation channel 13. Therefore, the circulation effect of the oil way can be enhanced, the oil cavities 30 are arranged at two ends of the heat radiation body, and the oil cavity 30 at the lower end flows to the oil cavity 30 at the upper end after being heated, so that the upper end of the heat radiation body 10 can achieve a good heating effect.
With further reference to fig. 3 to 5, in an embodiment of the present invention, the port area of the connecting channel 15 communicating with the main heat dissipating channel 11 is defined as S1, the port area of the connecting channel 15 communicating with the auxiliary heat dissipating channel 13 is defined as S2, and S1 > S2.
The connection port of the connection channel 15 to the main heat dissipation channel 11 is set to be large, and the connection port of the connection channel 15 to the auxiliary heat dissipation channel 13 is set to be small. Therefore, the heat conducting oil in the main heat dissipation channel 11 can be guided to the auxiliary heat dissipation channel 13 more smoothly. When the heat conduction oil of the main heat dissipation channel 11 passes through the connecting channel 15, an effect of accelerating circulation can be generated, and the circulation efficiency of the heat conduction oil is improved.
Further, the channel cross-sectional area of the connecting channel 15 gradually decreases from one end of the primary heat dissipation channel 11 to one end of the secondary heat dissipation channel 13.
The cross-sectional area of connecting channel 15 sets up to reduce gradually, is the shape that reduces gradually for the conduction oil can obtain lasting intraductal pressure and accelerated, further promotes the circulation efficiency of conduction oil in connecting channel 15.
In an embodiment of the present invention, the height of the port of the connecting channel 15 communicating with the main heat dissipating channel 11 is defined as H1, the height of the port of the connecting channel 15 communicating with the auxiliary heat dissipating channel 13 is defined as H2, and H1 > H2.
It is to be understood that the height value may refer to a height from the placement surface when the heating body 10 is vertically placed. The height value of the port of the connecting channel 15 communicated with the main heat dissipation channel 11 is higher than that of the auxiliary heat dissipation channel 13, and the heat conduction in the connecting channel 15 can be accelerated by utilizing the gravitational potential energy of the heat conduction oil, so that the circulation efficiency of the heat conduction oil is further improved. It will be appreciated that the above-described port size setting of the connecting passage 15, the tapering setting of the connecting passage 15, and the height value setting herein may be combined, and that the combination of the three may achieve a more optimal oil circulation effect. Of course, the scheme can be independently arranged, and the effect of accelerating circulation of the oil path can be achieved.
Referring to fig. 3 to 5 in combination, when the auxiliary heat dissipation channels 13 are provided, the number of the auxiliary heat dissipation channels 13 may be set to one, or may be set to two or more. In an embodiment, the number of the auxiliary heat dissipating channels 13 is at least two, and at least two auxiliary heat dissipating channels 13 are disposed on two opposite sides of the main heat dissipating channel 11.
The internal volume of the main heat dissipation channel 11 is larger than that of the auxiliary heat dissipation channel 13, and the number of the auxiliary heat dissipation channels 13 is at least two, so that the circulation of an oil circuit can be facilitated. It is further possible to set the total volume of the plurality of auxiliary heat dissipation channels 13 to be the same as the internal volume of the main heat dissipation channel 11.
Further, when the connection passage 15 is provided, the number of the connection passage 15 may be one, or two or more. Referring to fig. 3 to 5, the number of the connecting channels 15 is at least two, and the at least two connecting channels 15 are symmetrically disposed on two opposite sides of the main heat dissipation channel 11. The two connecting channels 15 are symmetrically arranged, so that the processing and the arrangement of the connecting channels 15 can be facilitated, and the processing technology of the connecting channels 15 is simplified.
Alternatively, the number of the connecting channels 15 is at least two, and the at least two connecting channels 15 are arranged in a staggered manner along the extending direction of the main heat dissipation channel 11. The connecting channels 15 are arranged in a staggered mode, so that the heat dissipation circulation area of the oil way can be increased relatively, and meanwhile, the circulation of the oil way can be facilitated.
With combined reference to fig. 3, 6 and 7, in an embodiment of the present invention, the main heat dissipation channel 11 includes a first port 111 and a second port 113 that are communicated with each other, and the first port 111 and the second port 113, and a port area of the first port 111 is larger than a port area of the second port 113.
Set up the first port 111 of the main heat dissipation passageway 11 of radiator 10 and the port area of second port 113 to different, the area of first port 111 is greater than the area of second port 113, thereby make the conduction oil enter into main heat dissipation passageway 11 back from first port 111, can make the velocity of flow of conduction oil increase when flowing out via second port 113, be seal structure because of the inside whole of oil spit of fland room heater 100, therefore, the increase of the conduction oil velocity of flow of second port 113 department, can drive the increase of whole conduction oil fluid speed, under the prerequisite that does not change oil spit of fland room heater 100 heat-generating body power, just can realize promoting the inner loop of the conduction oil of radiator 10, shorten the heat time, promote heating efficiency, realize the rapid heating up of oil spit of fland room heater 100. The circulation efficiency of the conduction oil of whole oil circuit is promoted, also makes the circulation efficiency who is in the conduction oil of connecting channel 15 promote, and the heating time can further be shortened in the two combination, promotes heating efficiency.
Further, the cross-sectional area of the main heat dissipation channel 11 in the pipe is gradually reduced from the first port 111 to the second port 113. That is, the cross-sectional area of the internal flow path of the heat dissipation channel is gradually reduced, so that the heat conduction oil can smoothly circulate in the heat dissipation channel, and the circulation of the heat conduction oil is promoted to be improved.
The ratio of the port area S3 of the first port 111 to the port area S4 of the second port 113 is: 2.8 is less than or equal to S3/S4 is less than or equal to 4.1.
Based on the existing oil heater 100, when the proportional range of the first port 111 and the second port 113 is set, the area of the first port 111 cannot exceed the area of the second port 113 to be too large, and the area of the first port 111 is 4.1 times larger than the area of the second port 113, so that the whole assembly is not convenient. The area of the first port 111 cannot exceed the area of the second port 113 too small, and the area of the first port 111 is 2.8 times smaller than the area of the second port 113, which may affect the flow rate of the liquid. Thus, the present application sets the ratio of the first port 111 and the second port 113 to range from 2.8 to 4.1, for example to 2.8, 3.0, 3.1, 3.5, 3.8, 4.0, 4.1.
Further, the following range values may be used alone in combination with the above-mentioned ratio parameters. For example, the port area S3 of the first port 111 has a value in the range of 1.17 x 10-4m2≤S3≤1.53*10-4m2The port area S4 of the second port 113 has a value in the range of 2.87 x 10-5m2≤S4≤5.46*10-5m2. The range of the port area of the first port 111 is 1.17 x 10-4m2To 1.53 x 10-4m2The port area of the second port 113 has a value in the range of 2.87 x 10-5m2To 5.46 x 10-5m2Also in view of the overall assembly effect and flow rate settings. For example, the following settings may be adopted: (S1 ═ 1.17 × 10-4m2，S2＝2.87*10- 5m2)，(S1＝1.5*10-4m2，S2＝3.1*10-5m2)，(S1＝1.53*10-4m2，S2＝5.46*10-5m2)。
In an embodiment of the present invention, the main heat dissipation channel 11 is a straight tube; alternatively, the main heat dissipation channel 11 is a helical tubular arrangement.
The straight tubular main heat dissipation channel 11 is adopted, the circulation speed of heat conduction oil is high, and the heat conduction oil can flow from one oil cavity 30 to the other oil cavity 30 quickly. The spiral tubular arrangement can increase the contact heat dissipation area. The arrangement of the auxiliary heat dissipation channel 13 may be similar to that of the main heat dissipation channel 11, and will not be described herein.
The port area of both ends of the secondary heat dissipation channel 13 may be set smaller than the port area of the second port 113.
The port areas of both ends of the auxiliary heat dissipation channel 13 are set smaller than the port area of the second port 113, because the port area of the second port 113 is smaller than the port area of the first port 111. That is, the port areas of both ends of the auxiliary heat dissipation channel 13 are smaller than the port areas of the first port 111 and the second port 113 of the heat dissipation channel. The heat conducting oil passes through the first port 111 with smaller resistance after being heated and expanded, then flows into the other oil cavity 30 in the heat dissipation channel, and then is cooled and flows back through the auxiliary heat dissipation channel 13. This results in effective circulation of the oil path.
And/or the port areas at the two ends of the auxiliary heat dissipation channel 13 are equal. The areas of the ports at the two ends of the auxiliary heat dissipation channel 13 are set to be equal, so that the auxiliary heat dissipation channel 13 can be conveniently machined.
With reference to fig. 4 and 5, when the heat sink is provided, an integrally formed heat sink may be provided, or two separate heat sink fins 10a may be provided, and the two heat sink fins 10a are fastened and connected to form one heat sink. For example, in one embodiment: the heat radiator 10 comprises two heat radiating fins 10a, each heat radiating fin is provided with a main heat radiating cavity 11a, an auxiliary heat radiating cavity 13a and a connecting cavity 15a, and the two heat radiating fins are buckled and connected to enable the main heat radiating cavities 11a of the two heat radiating fins 10a to form a main heat radiating channel 11 and two auxiliary heat radiating cavities 13a of the two heat radiating fins to form an auxiliary heat radiating channel 13 and two connecting cavities 15a of the two heat radiating fins to form a connecting channel 15.
Two radiating fins 10a are connected to form a radiator 10, so that the processing and the arrangement of an internal pipeline are facilitated, and meanwhile, the replacement and the maintenance are also facilitated.
Further, referring to fig. 4, the position of the connection cavity 15a of one of the heat dissipation fins 10a is opposite to the position of the connection cavity 15a of the other heat dissipation fin 10 a. That is, the two heat dissipating fins 10a may be provided to the same specification. The positions of the connecting cavities 15a are arranged oppositely, which means that the connecting cavities 15a of one radiating fin 10a and the connecting cavities of the other radiating fin 10a can be superposed with each other by projection on the same plane. Mutually coincident means that they may be completely coincident or partially coincident, and are not limited thereto.
During processing, one heat dissipation fin 10a can be aligned with the connection cavity 15a of another heat dissipation fin 10a, and the heat dissipation body 10 can be directly formed by buckling connection. Therefore, the processing of the heat radiator 10 is facilitated, and the heat radiating fins 10a are made into a uniform specification, so that the assembly of the heat radiating fins 10a is facilitated. The two connecting cavities 15a are arranged opposite to each other, so that the overall flow of the connecting channel 15 can be increased, and the heat conduction oil passing through the connecting channel 15 is smoother.
Alternatively, referring to fig. 5, the connection cavity 15a of one of the heat dissipating fins 10a is offset from the connection cavity 15a of the other heat dissipating fin 10 a.
The connection cavities 15a are arranged in a staggered manner, which means that the connection cavities 15a of one cooling fin 10a and the connection cavities 15a of another cooling fin 10a can be staggered with respect to each other in a projection onto the same plane. The mutually offset connection cavities 15a are not overlapped at all, and the surface area of the radiating fin 10a can be utilized with maximum efficiency. During assembly, the staggered connecting cavities 15a can increase the heat dissipation area and improve the heat utilization efficiency of the oil heater 100.
With reference to fig. 1 and fig. 2, the present invention further provides an oil-filled warmer 100, where the oil-filled warmer 100 includes a heat dissipation body 10, and the specific structure of the heat dissipation body 10 refers to the above embodiments, and since the oil-filled warmer 100 adopts all technical solutions of all the above embodiments, at least all beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is provided herein. The oil heater 100 further includes a heating element 50, and the heating element 50 is disposed in an oil chamber 30.
Referring to fig. 2 and fig. 3 again, in an embodiment of the present invention, the number of the heat sinks 10 is at least two, and at least two heat sinks 10 are arranged at intervals along the extending direction of the heating element 50.
The two heat sinks 10 and the main heat dissipation channels 11 of the two heat sinks can also form an integral circulation loop of heat conduction oil. During heating, the flow rate of the heat conduction oil is increased after the heat conduction oil enters from the first port 111 of one heat radiation body 10 and flows out through the second port 113, then the heat conduction oil flows into the second port 113 adjacent to the heat radiation body 10, and the flow rate of the heat conduction oil can be increased when the heat conduction oil flows into the first port 111 of the heat radiation body 10 from the second port 113 of the heat radiation body 10, so that the circulation of the heat conduction oil in the two heat radiation bodies 10 is realized.
Referring to fig. 2 and 3 again, in an embodiment of the present invention, an oil chamber 30 in which the heating member 50 is disposed is defined as a heating oil chamber, the heating member 50 extends along an extending direction of the heating oil chamber, a portion of the heating oil chamber not covered by the heating member 50 is a cold section, and a portion of the heating oil chamber covered by the heating member 50 is a hot section; the heat radiator 10 in the hot section is communicated with the heating oil chamber 30 through a first port 111 of the main heat dissipation channel 11, and the heat radiator 10 in the cold section is communicated with the heating oil chamber through a second port 113 of the main heat dissipation channel 11.
The heat dissipation channels between the heat dissipation body 10 at the cold section position and the heat dissipation body 10 at the hot section position can also form an integral circulation loop of heat conduction oil. During heating, the temperature of the heat conducting oil at the hot section is increased rapidly, and the heat conducting oil can enter the first port 111 of the heating body 10 rapidly and flow out from the second port 113 at a higher speed. Then flows into the second port 113 of the heating body 10 at the cold section position, and flows into the first port 111 of the heating body 10 from the second port 113 of the heating body 10, thereby realizing the circulation of the heat conducting oil in the two heating bodies 10. On the basis of considering the uneven heating of the main heat dissipation channel 11, the internal channel of the main heat dissipation body 10 is asymmetrically arranged, so that the internal overall circulation flows from a hot section to a cold section, and the accelerated heat dissipation is facilitated.
