Technical Field

[0001] This utility model belongs to the field of coating technology, specifically a nano-coating chamber for a pressure-stabilizing oil cooler. Background Technology

[0002] Oil coolers are cooling devices used in industrial, power systems, and transportation vehicles for various kinetic components, supplying cooling fluids such as lubricating oil, hydraulic oil, and brake fluid. Currently, most oil coolers are made of metals such as aluminum alloy, stainless steel, and copper, and require anti-corrosion coating during manufacturing.

[0003] The current approach involves immersing the entire oil cooler in a solution of corrosion-resistant nanomaterials, followed by heating and baking to solidify the nanomaterials and form an anti-corrosion coating. However, due to the narrow internal channels of the oil cooler, it is difficult to fully fill and drain the nanomaterial solution. This residual solution creates resistance within the channels, affecting the quality of the oil cooler's operation. Therefore, a nano-coating chamber for a pressure-stabilizing oil cooler is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide a nano-coating chamber for a pressure-stabilizing oil cooler in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: a nano-coating chamber for a pressure-stabilizing oil cooler, comprising a coating chamber body, wherein the coating chamber body has a sealable coating chamber, and the coating chamber body is provided with a control panel and a negative pressure mechanism, an atomizing mechanism and a pressure monitor connected to the coating chamber. The negative pressure mechanism, the atomizing mechanism and the pressure monitor are all controlled by the control panel and are used to form a positive pressure and / or negative pressure state inside the coating chamber.

[0008] In a preferred embodiment, the atomizing assembly includes a one-way valve, a rotary joint, and an atomizing disc, wherein the flow direction of the one-way valve is from the liquid outlet of the liquid pump to the coating chamber.

[0009] In a preferred embodiment, the fixed end of the rotary joint is disposed on the one-way valve, the rotating end of the rotary joint is connected to the atomizing disc, and a plurality of atomizing nozzles are arranged circumferentially on the outer wall surface of the atomizing disc, and a plurality of outwardly inclined atomizing nozzles are arranged along the length of the atomizing nozzles.

[0010] In a preferred embodiment, a placement platform is provided directly below the atomizing component within the coating chamber, and the bottom of the placement platform is supported on the bottom wall of the coating chamber by multiple support columns.

[0011] In a preferred embodiment, the bottom wall of the coating chamber is provided with a downwardly sloping guide slope with a slope of 5° to 10°.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] Reference Figure 1-3 A nano-coating chamber for a pressure-stabilized oil cooler includes a coating chamber body 100 with a sealable coating chamber 110. The coating chamber body 100 is equipped with a control panel 160 and a negative pressure mechanism, an atomizing mechanism, and a pressure monitor 500 connected to the coating chamber 110. The negative pressure mechanism, atomizing mechanism, and pressure monitor 500 are all controlled by the control panel 160 to create a positive and / or negative pressure state inside the coating chamber 110. A segmented negative and positive pressure atomization coating method is used to coat the oil cooler. During the coating process, negative pressure coating is performed first, followed by a period of pressure stabilization, and then positive pressure coating. This method atomizes the nano-coating liquid and evenly coats it onto the surface of the oil cooler, allowing for a more thorough and comprehensive coating of the dense inner cavity of the oil cooler, thereby improving the subsequent service quality of the oil cooler.

[0030] Furthermore, the negative pressure mechanism includes a vacuum pump 600 and a negative pressure pipeline 610 connected to the coating chamber 110. An electrically controlled valve is installed on the negative pressure pipeline 610. When drawing negative pressure, the vacuum pump 600 operates to create a negative pressure inside the coating chamber 110. When the pressure monitored by the pressure monitor 500 reaches the range set on the control panel 160, the electrically controlled valve closes. At this point, the coating chamber 110 is in a closed negative pressure environment, allowing for subsequent negative pressure atomization coating operations. The pressure monitor 500 is a pressure sensor or electronic pressure gauge that monitors the pressure changes inside the coating chamber 110 in real time to ensure a stable positive and / or negative pressure environment inside the coating chamber 110.

[0031] It should be noted that controlling the coordinated operation of electronic components through the control panel 160 is a technology that has been implemented and is well known in the prior art, and its principle will not be elaborated here.

[0032] Furthermore, the atomizing mechanism includes a liquid pump 300 and an atomizing assembly 800. The inlet end of the liquid pump 300 is connected to an external liquid supply system, and the outlet end of the liquid pump 300 is connected to the atomizing assembly 800 through a pipeline. The atomizing assembly 800 includes a one-way valve 810, a rotary joint 830, and an atomizing disc. The flow direction of the one-way valve 810 is from the outlet end of the liquid pump 300 to the coating chamber 110. The fixed end of the rotary joint 830 is disposed on the one-way valve 810, and the rotating end of the rotary joint 830 is connected to the atomizing disc. Multiple atomizing nozzles 820 are arranged circumferentially on the outer wall of the atomizing disc, and multiple sets of outwardly inclined atomizing nozzles 820 are arranged along their length. During subsequent pressurized coating operations, the nano-anti-corrosion coating is drawn into the atomizing component 800 by the pump 300 and then sprayed out through multiple atomizing nozzles 840 on the atomizing nozzle pipe 820. During spraying, the reaction force causes the atomizing nozzle pipe 820 and the atomizing disc to rotate, creating turbulence and allowing the atomized coating to diffuse quickly and fully into the coating chamber 110. The interior is under pressurized during coating discharge. Thanks to the one-way valve 810, leakage is prevented during atomization. The tilt angle of the atomizing nozzles 840 is 35°~55°. The pump 300 can be an industrial pump body.

[0033] It should be noted that the external liquid supply system (not shown in the figure) includes a nano-anti-corrosion coating storage tank, pipelines, flow meters, etc.

[0034] Furthermore, a placement platform 130 is provided directly below the atomizing component 800 within the coating chamber 110. The bottom of the placement platform 130 is supported on the bottom wall of the coating chamber 110 by multiple support columns. The bottom wall of the coating chamber 110 is provided with a downward-sloping guide slope 120 with a slope of 5°~10°. A waste discharge port 140 extending out of the coating chamber 100 is provided at the bottom of the guide slope 120. A second electrically controlled valve is provided on the waste discharge port 140. During the coating operation, the condensed droplets will drip downwards under their own weight and then flow down the slope of the guide slope 120 into the waste discharge port 140, and then be discharged through the waste discharge port 140.

[0035] In other embodiments, the placement stage 130 can also be designed as a rotatable structure, that is, an additional electric rotating seat is added to the bottom. At the same time, the placement stage 130 is designed with a tool for clamping the oil cooler, which can be centrifuged after coating, so that the internal nano coating can be more uniform and avoid the problems of microchannel blockage and local dripping caused by nano coating dipping.

[0036] Furthermore, the top of the coating chamber 100 is equipped with an electric pressure relief valve 200 that communicates with the coating chamber 110. One side of the coating chamber 110 is equipped with an openable door 150 on the coating chamber 100. When the coated oil cooler is removed later, the pressure can be relieved by the electric pressure relief valve 200 to restore the pressure inside the chamber to normal, ensuring the safety when taking out and putting in the oil cooler.

[0037] Furthermore, the coating chamber 100 is equipped with a cooling component 700 and a temperature sensor 400 extending into the coating chamber 110. The cooling component 700 is located on the side of the coating chamber 110. Both the cooling component 700 and the temperature sensor 400 are controlled by the control panel 160. After negative pressure coating and before positive pressure coating, the cooling component 700 is used to cool the coating chamber 110, thereby allowing the atomized nanomaterials filling the entire oil cooler to quickly condense and adhere to the surfaces of various internal components of the oil cooler. The cooling component 700 is either a semiconductor cooling chip (with a cooling fan added to the hot end) or uses a compressor for cooling.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
