AI Technical Summary
The existing flow channel structure of thick film water heaters for new energy vehicles results in low heat exchange efficiency, long flow channels, and high water resistance, leading to excessively large heater size and difficulty in meeting lightweight requirements.
The system employs an inlet and outlet groove within the fluid cavity of the heater housing, with turbulence-inducing columns arranged between them to form a "U"-shaped waterway. The turbulence-inducing columns promote fluid turbulence, thereby improving heat exchange efficiency, and stainless steel or aluminum alloy materials are used to reduce flow resistance.
It improves heat exchange efficiency, reduces flow resistance, and enables the miniaturization of the heater, meeting the requirements for automotive lightweighting.

TECHNICAL FIELD
[0001] The utility model relates to a new energy automobile vehicle wind, water heating heater, concretely relates to a high pressure water heating thick film heater flow channel structure. BACKGROUND
[0002] The thick film water heating heater commonly used in new energy automobile mainly adopts the ''M'' type flow channel structure as shown in the figure, the thick film water heating heater flow channel of this single way ''M'' type structure makes liquid mainly rely on the surface flow of specific pipe type, the appearance of this pipe type structure itself leads to its heat exchange efficiency low, flow channel long, water resistance big, and the single flow channel is affected by structure (has greater thickness), leads to thick film board design too big, then leads to the volume of heater assembly becomes big. Figure 1 SUMMARY
[0003] The utility model provides a structure design simple, flow resistance small, heat exchange fast and can make the volume of whole heater reduce high pressure water heating thick film heater flow channel structure.
[0004] In order to solve above-mentioned technical problem, the high pressure water heating thick film heater flow channel of the utility model, including the heater shell with water inlet and water outlet and the heating thick film board for closing in the fluid cavity top of heater shell, the edge of the fluid cavity of heater shell has a water inlet recess through with water inlet and a water outlet recess through with water outlet, still arrange multiple protruding turbulence column between water inlet recess and water outlet recess in the fluid cavity, the liquid that enters into water inlet recess through water inlet can be after turbulence column turbulence and then enter into water outlet recess and then discharge through water outlet.
[0005] The edge of the heater shell is provided with the ring groove located in the periphery of the fluid cavity, and the ring groove is provided with the sealing ring pressed between the heater shell and the heating thick film board.
[0006] The turbulence column is a cylindrical structure, a frustum type structure, an S type structure or a long strip type structure.
[0007] The heating thick film board is provided with a heating layer and a ceramic insulation layer printed thereon.
[0008] The base material of the heater shell is stainless steel, steel or aluminum alloy.
[0009] The height of the turbulence column is 10-50mm.
[0010] The turbulence column is directly formed on the inner surface of the base material in the flow cavity.
[0011] After the structure is used, the water inlet groove and the water outlet groove arranged at the edge of the fluid cavity of the heater shell and the plurality of turbulence columns arranged between the water inlet groove and the water outlet groove in the fluid cavity, thereby forming a "U" water channel through the water inlet groove and the water outlet groove, in use, the fluid can form turbulent flow through the turbulence columns, the fluid flow rate is increased, the thermal resistance is reduced, the water and the heating thick film plate are in contact through the flow, the heat exchange efficiency of the thick film heater and the fluid is improved, the heat exchange effect is fully achieved, the structure design is very simple, the manufacturing cost is low, the flow resistance is small, the heat exchange is fast, the overall volume can be reduced, and the light weight requirement of the automobile is met. BRIEF DESCRIPTION OF DRAWINGS
[0012] Figure 1 It is a flow channel schematic view of an existing conventional M-shaped thick film water heating heater;
[0013] Figure 2 It is a schematic view of the flow channel structure of the high-pressure water heating thick film heater.
[0014] Figure 3 It is a structural schematic view of the heater shell in the utility model. DETAILED DESCRIPTION
[0015] The flow channel structure of the high-pressure water heating thick film heater of the utility model will be further described in detail in combination with the drawings and the specific embodiments.
[0016] As shown in the drawings, the flow channel structure of the high-pressure water heating thick film heater of the utility model comprises a heater shell 3 with a water inlet 1 and a water outlet 2 and a heating thick film plate 5 used for closing the fluid cavity 4 top of the heater shell, the base material of the heater shell 3 is a metal material such as stainless steel, steel or aluminum alloy, the heating thick film plate 5 is provided with a heating layer and a ceramic insulation layer printed thereon, the edge of the heater shell 3 is provided with a ring groove 9 located at the periphery of the fluid cavity, the ring groove 9 is arranged with a sealing ring 10 pressed between the heater shell and the heating thick film plate, the left side of the fluid cavity of the heater shell 3 is provided with a water inlet groove 6 and the right side of the fluid cavity is provided with a water outlet groove 7, the water inlet groove 6 and the water outlet groove 7 are arranged with a plurality of turbulence columns 8 between the water inlet groove 6 and the water outlet groove 7 in the fluid cavity. Figure 2The right side edge of the fluid cavity of the heater shell 3 has a water outlet groove 7 through the water outlet, and the fluid cavity 4 is also arranged with multiple protruding spoiler columns 8 between the water inlet groove and the water outlet groove, wherein the spoiler columns 8 can be cylindrical structure, frustum structure, S-shaped structure or strip-shaped structure, etc., and the embodiment does not make strict limitation, and the new protrusion increases the heat dissipation area by 60%, since the cross-sectional shape of the water inlet groove 6 and the water outlet groove 7 is a semicircular groove structure, therefore the plane formed between the water inlet groove 6 and the water outlet groove 7 is the forming surface of the spoiler column 8, that is, the spoiler column 8 is directly formed on the inner surface of the base material in the flow cavity, and this structure can form two parallel flow channels by the water inlet groove 6 and the water outlet groove 7, meet the flow demand, and the liquid entering the water inlet groove through the water inlet can be disturbed by the spoiler column and then enter the water outlet groove and then be discharged through the water outlet.
[0017] Further, the height of the spoiler column 8 is 10-50mm, the height of the spoiler column 8 is lower than the height of the top surface of the flow cavity and has a height capable of forming turbulent flow from the heating thick film plate 5, so that the effect is optimal.
[0018] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples, and the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the present application should also belong to the protection scope of the present application.
