It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0035] The utility model provides a kind of electric oil heater, please refer to Figures 1 to 6 Electric oil heater includes multiple groups of pieces 10 connected in sequence;Each group of pieces 10 includes two pieces 11, and the two pieces 11 of each group of pieces 10 enclose oil guide channel and oil bag.

[0036] The inside of group of pieces 10 is filled with heat-conducting oil, which is filled in the inside of the body 1 of electric oil heater. When electric oil heater is powered on, the heating body 20 of electric oil heater generates heat, transfers heat to heat-conducting oil, and heat-conducting oil transfers heat to the body 1, exchanges heat with surrounding cold air through the structure of the body, and realizes heating.

[0037] Specifically, multiple groups of pieces 10 of electric oil heater are sequentially welded to form the body 1 of electric oil heater;The two pieces 11 of each group of pieces 10 are welded.

[0038] Specifically, the two pieces 11 of each group of pieces 10 enclose two oil bags, i.e. upper oil bag and lower oil bag.

[0039] Specifically, the piece 11 includes a protruding part 101 enclosing an oil bag;That is, the piece 11 includes two protruding parts 101, and the two protruding parts 101 of the piece 11 are an upper protruding part 1011 and a lower protruding part 1012 respectively;The upper protruding part 1011 of the piece 11 is used to enclose the upper oil bag, and the lower protruding part 1012 of the piece 11 is used to enclose the lower oil bag.

[0040] Specifically, the protruding part 101 has a protruding side surface 102 and a protruding end surface 103, and a round chamfer 104 is arranged between the protruding side surface 102 and the protruding end surface 103 of the protruding part 101;The radius of the round chamfer 104 is less than or equal to 4mm.

[0041] Specifically, the radius of the round chamfer 104 of the upper protruding part 1011 and the round chamfer 104 of the lower protruding part 1012 of the piece 11 are equal.

[0042] Optionally, the radius of the round chamfer 104 is greater than or equal to 1 mm and less than or equal to 4 mm.

[0043] Optionally, the radius of the round chamfer 104 is greater than or equal to 1 mm and less than or equal to 3 mm.

[0044] Optionally, the radius of the round chamfer 104 is 2 mm.

[0045] In the present application, the two Ding pieces 11 of the Ding piece group 10 are respectively a first Ding piece 111 and a second Ding piece 112; the protruding height of the protruding part 101 of the first Ding piece 111 is greater than the protruding height of the protruding part 101 of the second Ding piece 112.

[0046] Specifically, the first Ding piece 111 is also called a large Ding piece, and the second Ding piece 112 is also called a small Ding piece.

[0047] Specifically, the protruding height of the protruding part 101 of the first Ding piece 111 is 18 mm.

[0048] Specifically, the protruding height of the protruding part 101 of the second Ding piece 112 is greater than or equal to 12 mm and less than or equal to 17 mm. That is, the oil package height of the Ding piece group 10 is greater than or equal to 30 mm and less than or equal to 35 mm.

[0049] Optionally, the protruding height of the protruding part 101 of the second Ding piece 112 is 13.5 mm. That is, the oil package height of the Ding piece group 10 is 31.5 mm.

[0050] By reducing the protruding height of the protruding part 101 of the second Ding piece 112, the oil package height of the Ding piece group 10 is reduced, so that the total length of the Ding body 1 of the electric oil heater is reduced, the volume is reduced, the structure is compact, the amount of heat conducting oil is reduced, the floor area of the electric oil heater is reduced, and the cost is reduced.

[0051] For example, the electric oil heater includes 13 Ding piece groups 10, which can shorten the total length of the Ding body 1 by about 50 mm, reduce the volume by about 14%, and reduce the amount of heat conducting oil by about 10.5%.

[0052] Specifically, in each Ding piece 11, the protruding heights of the two protruding parts 101 are equal, that is, the protruding height of the upper protruding part 1011 is equal to the protruding height of the lower protruding part 1012.

[0053] In the present application, in any two adjacent said group of plates 10, the protruding part 101 of the second plate 112 of the former said group of plates 10 is connected with the protruding part 101 of the first plate 111 of the latter said group of plates 10, so that a welding gap 105 is formed at the round chamfer 104 of the two adjacent and connected protruding parts 101.

[0054] If the radius of the round chamfer 104 is large, the welding gap 105 at the round chamfer 104 will be large, and it is difficult to completely fill the welding gap 105 by one spraying. In order to solve the spraying appearance quality and spraying breakage problems at the welding gap 105, secondary supplementary spraying is needed, which leads to long spraying time, large spraying powder consumption and increased spraying cost. If the secondary supplementary spraying is not performed, the bottom of the welding gap 105 will be exposed and rusted, which affects the service life and experience of the product.

[0055] The radius of the round chamfer 104 in the present application is small, so that the welding gap 105 formed at the round chamfer 104 of the two adjacent and connected protruding parts 101 is small. Therefore, when spraying is performed at the welding gap 105, the spraying can be completed at one time without the need for secondary supplementary spraying. The oil package will not have the problems of spraying bottom exposure and breakage, the appearance quality of the electric oil heater is ensured, the spraying time and spraying powder consumption are reduced, and the spraying cost is reduced and the spraying efficiency is improved.

[0056] For example, the spraying time can be reduced by 10%, and the spraying powder consumption can be reduced by 30%.

[0057] Specifically, the plate 11 is formed by die stamping and stretching, the protruding height of the protruding part 101 is reduced, so that the radius of the round chamfer 104 is reduced, and the problem of cracking during die stamping and stretching is avoided.

[0058] In the present application, in each said group of plates 10, the second plate 112 is located on the side close to the tail end of the electric oil heater of the first plate 111.

[0059] In the present application, in the direction from the protruding bottom end to the protruding top end of the protruding part 101, the cross section of the protruding part 101 perpendicular to the protruding direction gradually decreases; wherein the protruding end face of the protruding part 101 is the end face of the protruding top end of the protruding part 101.

[0062] The protruding part 101 of the tontine sheet 11 comprises a protruding side surface 102 and a protruding end surface 103, and a round chamfer 104 is arranged between the protruding side surface 102 and the protruding end surface 103, and the radius of the round chamfer 104 is less than or equal to 4 mm.

[0063] The two tontine sheets 11 are respectively a first tontine sheet 111 and a second tontine sheet 112, and the protruding height of the protruding part 101 of the first tontine sheet 111 is greater than the protruding height of the protruding part 101 of the second tontine sheet 112.

[0064] In any two adjacent tontine sheet groups 10, the protruding part 101 of the second tontine sheet 112 of the former tontine sheet group 10 is connected with the protruding part 101 of the first tontine sheet 111 of the latter tontine sheet group 10, so that a welding gap 105 is formed at the round chamfers 104 of the two adjacent and connected protruding parts 101.

[0065] The radius of the round chamfer 104 of the present application is small, so that the welding gap 105 formed at the round chamfers 104 of the two adjacent and connected protruding parts 101 is small, and thus the spraying can be completed at one time without the need for secondary supplementary spraying; the spraying bottom exposure and wire breaking problems do not occur at the oil pocket, the appearance quality of the electric oil tontine is ensured, the spraying time and the amount of spraying powder are reduced, and thus the spraying cost is reduced and the spraying efficiency is improved.
