Description

Technical Field

[0001] The utility model relates to the technical field of processing alternative composite plate pipeline joints, in particular to a double-layer powder-sprayed dust cap. Background Art

[0002] In the related technology, the battery pack uses a cold plate heat exchanger for cooling. The cold plate heat exchanger is formed by welding two aluminum plates. One plate is a stamped plate with a flow channel, and the other plate is a flat plate. A cooling flow channel is defined between the stamped plate and the flat plate, and the welded joint on the flat plate is connected to the cooling flow channel. The refrigerant enters the heat exchanger through the joint inlet, circulates in the cooling flow channel, and finally converges and flows out of the joint outlet, completing the circulation of the refrigerant in the cooling flow channel. This type of heat exchanger uses the refrigerant's evaporation and heat absorption characteristics to exchange heat with the power battery, thereby achieving the purpose of cooling the power battery.

[0003] In existing cold plate heat exchangers, pipe fittings and joints usually use single-layer dust caps. During the processing, the dust caps need to be put into the furnace after powder spraying. After the dust caps are solidified, the powder on the dust caps falls onto the product when they are pulled out, causing product contamination. Utility Model Content

[0004] The utility model aims to provide a double-layer powder spraying dustproof cap to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-layer powder spray dust cap, including a pipe joint body, the pipe joint body is composed of a first connecting pipe at the upper end, a second connecting pipe on the side and a three-way joint, and the first connecting pipe and the second connecting pipe are both provided with at least two layers of dust caps.

[0006] Further optimized, the two layers of dust caps include a first dust cap, a second dust cap, a third dust cap and a fourth dust cap which are mounted on the first connecting tube and the second connecting tube.

[0007] Further optimized, the first dust cap and the second dust cap are mounted on a third dust cap and a fourth dust cap.

[0008] Further optimized, the other ends of the first dust cap and the second dust cap away from the three-way joint are each provided with a first protrusion and a second protrusion that are clip-connected to the third dust cap and the fourth dust cap.

[0009] For further optimization, a rectangular snap-in groove is provided at one end of the fourth dust cap close to the three-way joint.

[0010] Further optimized, the other end of the third dust cap close to the three-way joint is provided with an arc-shaped snap-in groove, and the rectangular snap-in groove is arranged inside the arc-shaped snap-in groove.

[0011] Beneficial Effects

[0012] The double-layer powder spray dust cap provided by the utility model can replace the problems of large pollution and large consumption in the traditional single-layer dust cap by adding a dust cap, while avoiding environmental pollution caused by the product during the process of manufacturing, packaging and transportation, and effectively preventing the product from being contaminated by dust falling on the surface of the product.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1-5 As shown, a double-layer powder spray dust cap includes a pipe joint body 1, which is composed of a first connecting pipe 10 at the upper end, a second connecting pipe 11 at the side, and a three-way joint 12. The first connecting pipe 10 and the second connecting pipe 11 are both sleeved with at least two layers of dust caps.

[0021] In this embodiment, the two-layer dust cap includes a first dust cap 5, a second dust cap 6, a third dust cap 3 and a fourth dust cap 4 which are mounted on the first connecting tube 10 and the second connecting tube 11. The third dust cap 3 and the fourth dust cap 4 are mounted on the first dust cap 5 and the second dust cap 6. The setting of the two-layer dust cap avoids the problem of product contamination caused during the transportation and manufacturing process of the entire product.

[0022] The other ends of the first dust cap 5 and the second dust cap 6 away from the three-way joint 12 are provided with a first protrusion 8 and a second protrusion 9 which are clamped and connected with the third dust cap 3 and the fourth dust cap 4. The provision of the protrusions ensures that the first dust cap 5 and the second dust cap 6 will not fall off during transportation and the manufacturing process, and the clamping is more stable.

[0023] A rectangular snap-in groove 13 is provided at one end of the fourth dust cap 4 close to the three-way joint 12 . The rectangular snap-in groove 13 is provided to snap-in with the three-way joint 12 more firmly.

[0024] The other end of the third dust cap 3 close to the three-way joint 12 is provided with an arc-shaped snap-in groove 14 , which is snap-fitted to the upper end of the rectangular snap-in groove 13 and fixedly snap-fitted to the three-way joint 12 to ensure that it does not fall off, and the rectangular snap-in groove 13 is arranged inside the arc-shaped snap-in groove 14 .

[0025] It replaces the traditional single-layer dust cap which is highly polluting and consuming. It will not pollute the environment during the manufacturing process, packaging and transportation, and effectively prevents customer complaints caused by dust falling on the product surface.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
