Abstract
Description
Technical Field
[0001] The utility model relates to an aluminum flat tube, in particular to a full-automatic wide-width multi-row heat exchange aluminum flat tube for a new energy battery pack, belonging to the technical field of heat exchange aluminum flat tubes for new energy battery packs. Background Technique
[0002] The microchannel aluminum flat tube (also known as "parallel flow aluminum flat tube") is a thin-walled, porous flat tube material made of refined aluminum rods, through hot extrusion and surface zinc spraying anti-corrosion treatment. It is mainly used in air-conditioning systems of various refrigerants as pipeline components for carrying new environmentally friendly refrigerants. Using new environmentally friendly refrigerants is the key material for a new generation of parallel flow microchannel air-conditioning heat exchangers, including heat exchange aluminum flat tubes for new energy batteries.
[0003] The Chinese published patent (publication number: CN 218123530 U) discloses a direct cooling and direct heating heat exchanger stamping plate and flat tube structure for a new energy battery pack, including a heat exchanger composed of a flow channel plate, an equalizing plate, a flat tube, a reinforcing strip, and a water cooling joint. The water cooling joint is arranged at one end of the flow channel plate and the equalizing plate, the flat tube is arranged between the flow channel plate and the equalizing plate, and the flow channel plate is arranged above the equalizing plate away from the battery pack. The beneficial effects of the utility model are as follows: The main structure of the heat exchanger is composed of an equalizing plate, a flow channel plate, and a flat tube after brazing, forming a through flow channel in the middle. After the refrigerant passes through the flow channel, the battery pack heat exchange and temperature equalization effect are realized through the equalizing plate and the flat tube, ensuring the heat exchange capacity and temperature equalization performance of the heat exchanger (temperature difference < 5°C). Through the flow channel plate shunt design of the flat tube (the flat tube is divided into 1-3-5-7), the flow rate of each flow path is ensured to be uniform, ensuring the direct cooling and direct heating function.
[0004] During the use of the aluminum flat tube, since the aluminum flat tube is in a new energy battery, the battery will heat up when the vehicle is running, and then the working environment of the aluminum flat tube is relatively harsh. When the aluminum flat tube does not have the abilities of wear resistance, corrosion resistance, and high temperature resistance, the service life of the aluminum flat tube may be shortened due to the harsh working environment, resulting in the aluminum flat tube being unable to perform heat exchange work on the new energy battery. At this time, due to the too high battery temperature, it may also cause the battery to catch fire, reducing the safety of the vehicle during driving. Therefore, a full-automatic wide-width multi-row heat exchange aluminum flat tube for a new energy battery pack is proposed. Content of the Utility Model
[0005] In view of this, the utility model provides a full-automatic wide-width multi-row heat exchange aluminum flat tube for a new energy battery pack to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.
[0006] The technical solution of the utility model is realized as follows: It includes an aluminum flat tube body, a high-temperature resistant mechanism, a wear-resistant mechanism, and a corrosion-resistant mechanism. Through holes are provided at both the top and bottom of the aluminum flat tube body. A high-temperature resistant mechanism is arranged on the surface of the aluminum flat tube body. A wear-resistant mechanism is arranged on the surface of the high-temperature resistant mechanism. A corrosion-resistant mechanism is arranged on the surface of the wear-resistant mechanism.
[0007] Further preferably, the high-temperature resistant mechanism includes an epoxy resin coating, which is coated on the surface of the aluminum flat tube body. A phosphate lead powder coating is coated on the side of the epoxy resin coating away from the aluminum flat tube body. A polyvinyl chloride resin coating is coated on the side of the phosphate lead powder coating away from the epoxy resin coating.
[0008] Further preferably, the wear-resistant mechanism includes high-density polyethylene, which is coated on the side of the polyvinyl chloride resin coating away from the phosphate lead powder coating. A high-strength nano-coating is coated on the side of the high-density polyethylene away from the polyvinyl chloride resin coating. A chromium carbide coating is coated on the side of the high-strength nano-coating away from the high-density polyethylene.
[0009] Further preferably, the corrosion-resistant mechanism includes a polyurethane waterproof coating, which is coated on the side of the chromium carbide coating away from the high-strength nano-coating. A nano waterproof coating is coated on the side of the polyurethane waterproof coating away from the chromium carbide coating. Zinc is coated on the side of the nano waterproof coating away from the polyurethane waterproof coating.
[0010] Further preferably, a heat-conducting gasket is adhesively bonded to the front side of the aluminum flat tube body through PP glue, and the material of the heat-conducting gasket is silica gel.
[0011] Further preferably, a wireless temperature sensing device is fixedly installed at the top of the front side of the aluminum flat tube body, and the wireless temperature sensing device is wirelessly connected to an in-vehicle computer.
[0012] Further preferably, heat exchange fin tubes are communicated with both the left and right sides of the top of the aluminum flat tube body, and fin tube interfaces are fixedly installed at the ends of the heat exchange fin tubes away from the aluminum flat tube body.
[0013] Due to the adoption of the above technical solutions in the embodiments of the utility model, it has the following advantages:
[0014] 1. By setting the high-temperature resistant mechanism, the wear-resistant mechanism, and the corrosion-resistant mechanism, the utility model can protect the aluminum flat tube, reduce the problem that the aluminum flat tube may be damaged under harsh working conditions, thereby extending the service life of the aluminum flat tube, avoiding the problem of deformation of the aluminum flat tube due to corrosion, friction, or high temperature, improving the use quality of the aluminum flat tube, ensuring the normal heat exchange function of the battery, and avoiding the situation of spontaneous combustion of the battery due to the inability of the aluminum flat tube to exchange heat due to damage.
[0015] Second, the utility model can achieve the effect of high temperature resistance on the aluminum flat tube body by setting a high temperature resistant mechanism, avoiding the situation that when it contacts the battery, the battery is damaged due to the too high temperature during the working state. By setting a wear-resistant mechanism, the wear resistance of the aluminum flat tube body can be improved, thereby reducing the damage of the aluminum flat tube body caused by external friction and preventing the situation that the aluminum flat tube body cannot perform heat exchange work due to damage.
