Description

Technical Field

[0001] The present invention belongs to the technical field of automotive air conditioning components, and particularly relates to an evaporator flange dip coating sealing device. Background Art

[0002] After the existing evaporator with a perforated flange structure is assembled into the air conditioning housing, the upper surface of the flange is exposed, so attention must be paid to the appearance quality of the upper surface of the flange. When the evaporator of this structure is subjected to surface dip coating treatment, it is necessary to prevent the dip coating solution from entering the interior of the evaporator core body, and it is not allowed for the dip coating solution to contact the upper surface of the flange. If conventional silicone plugs are used to block the pipe orifices and flange holes, on the one hand, four different specifications of plugs are required, which is not conducive to material management, and there are many plugging operations and a slow beat; on the other hand, the flange surface will still be contaminated by the dip coating solution. On the third hand, during the drying process after the evaporator is dip coated, the plugs will be extruded due to the internal air being heated, causing the plugs to fall inside the equipment. If an overall semi-wrapping is used and a radial sealing method is adopted inside, the dip coating layer around the inner seal ring of the cover will gradually solidify and accumulate during the drying process, affecting the installation and unloading of the cover and also affecting the sealing performance. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the above background art and provide an evaporator flange dip coating sealing device.

[0004] The technical solution adopted by the present invention is: an evaporator flange dip coating sealing device, including a protective pad on the flange surface, a protective cover, and a clamping component; one side of the protective pad is attached to the upper surface of the flange, and the other side is embedded in the protective cover, and the clamping component axially clamps the protective cover and the flange.

[0005] A further preferably structured, the protective pad is a silicone soft pad based on the outer contour of the upper surface of the flange.

[0006] A further preferably structured, the protective pad includes an upper surface of the protective pad and a lower surface of the protective pad. Among them, the lower surface of the protective pad fits with the upper flange holes of the flange; an avoidance hole is provided in the middle of the protective pad for the protruding pipe orifice on the flange to pass through.

[0007] A further preferably structured, further includes a wear-resistant piece, which is embedded in the protective cover.

[0008] A further preferably structured, one end face of the protective cover is provided with a first profiling structure that fits with the upper surface of the protective pad, and the other end face is provided with a second profiling structure for placing the wear-resistant piece.

[0009] A further preferred structure is that a pipe orifice profiling structure matching the protruding pipe orifice on the flange is provided in the middle of the protective cover to avoid the protruding pipe orifice on the flange.

[0010] The upper part of the protective cover uses a stainless steel sheet to avoid abrasion.

[0011] A further preferred structure is that the clamping component is a C-shaped clamp that clamps the flange, the protective pad, and the protective cover as a whole, and uses pressure to seal the upper surface of the flange and the pipe orifice to prevent the dipping solution from entering the interior of the new evaporator body.

Detailed implementation mode

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, which are convenient for clearly understanding the present invention, but they do not constitute a limitation to the present invention.

[0029] As Figure 1-2 shown, the present invention includes a protective pad 2, a protective cover 3 and a clamping component 5 on the surface of the flange 1.1; one side of the protective pad 2 is attached to the upper surface 1.2 of the flange, and the other side is embedded in the protective cover 3, and the clamping component 5 axially clamps the protective cover 3 and the flange 1.1.

[0030] As Figure 3 shown, the protective pad 2 is a silica gel soft pad based on the outer contour of the upper surface of the flange 1.1.

[0031] The protective pad 2 includes an upper surface 2.1 of the protective pad and a lower surface 2.2 of the protective pad. Among them, the lower surface 2.2 of the protective pad is attached to the flange hole 1.4 on the upper flange 1.1; a relief hole 2.3 is provided in the middle of the protective pad 2 for the protruding pipe orifice 1.5 on the flange 1.1 to pass through.

[0032] As Figure 6 shown, it further includes a wear-resistant sheet 4, which is embedded in the protective cover 3.

[0033] As Figure 4 , Figure 5 shown, one end surface of the protective cover 3 is provided with a first profiling structure 3.1 that fits with the upper surface 2.1 of the protective pad, and the other end surface is provided with a second profiling structure 3.3 for placing the wear-resistant sheet 4. The first profiling structure 3.1 matches the outer contour of the protective pad 2, and the second profiling structure 3.3 matches the outer contour of the wear-resistant sheet 4.

[0034] A pipe orifice profiling structure 3.2 that cooperates with the protruding pipe orifice 1.5 on the flange 1.1 is provided in the middle of the protective cover 3 to avoid the protruding pipe orifice on the flange.

[0035] Above the protective cover, stainless steel sheets are used to avoid abrasion.

[0036] As Figure 7 As shown, the clamping component 5 is a C-shaped clamp that clamps the flange 1.1, the protective pad 2, and the protective cover 3 as a whole, and uses pressure to seal the upper surface of the flange and the pipe orifice to prevent the dipping solution from entering the interior of the new evaporator body.

[0037] The clamping component 5 includes a first clamping surface 5.1 on the inner side below the C-shaped clamp and a second clamping surface 5.2 on the inner side above. The first clamping surface 5.1 fits with the lower surface 1.3 of the flange, and the second clamping surface 5.2 fits with the wear-resistant sheet 4.

[0038] A U-shaped avoidance groove 5.4 is formed on the first clamping surface 5.1 for the protruding pipe orifice 1.5 on the flange 1.1 to pass through.

[0039] The clamping component 5 is locked by a wing bolt 5.3, which is convenient for operation.

[0040] Combined Figure 8 As shown, the installation process of the present invention: The protective pad 2 is installed in the profiling of the protective cover 3 so that the upper surface 2.1 of the protective pad fits with the first profiling structure 3.1, and then the protective cover 3 is covered on the flange 1.1 of the evaporator so that the lower surface 2.2 of the protective pad fits with the upper surface 1.2 of the flange. The lower surface 2.2 of the protective pad seals the flange hole 1.4, and the protruding pipe orifice 1.5 on the flange 1.1 is just located in the pipe orifice profiling structure 3.2 of the protective cover 3. Then, the wear-resistant sheet 4 is placed in the second profiling structure 3.3 of the protective cover 3, and then the clamping component 5 clamps the flange 1.1 and the protective cover 3 so that the first clamping surface 5.1 fits with the lower surface 1.3 of the flange and the second clamping surface 5.2 fits with the wear-resistant sheet 4. Finally, the wing bolt 5.3 is locked, and the evaporator flange 1.1 is tightly pressed and sealed by the protective pad 2. Neither the upper surface 1.2 of the evaporator flange nor the interior of the core will come into contact with the dipping solution, achieving the purpose of protection.

[0041] The present invention can not only block the pipe orifice 1.5 of the evaporator assembly A, but also block the flange hole 1.4 and the flange surface, and can withstand a certain internal pressure. The loading and unloading actions are simple and the rhythm is relatively fast. Moreover, it can protect the appearance of the upper surface of the perforated flange. This device avoids the falling-off phenomenon during the drying process, and the loading and unloading actions are simple and the production rhythm is relatively fast.
