Aluminium Brazing Furnace

Aluminum Brazing Furnace: it is used for brazing of air conditioners, oil coolers, radiators, air conditioner evaporators, condensers, radar network antennas, waveguides, and various plate-warped or tube-fin heat exchangers for automotive environmental protection products. It can also vacuum braze aluminum water-cooled plates and air-cooled boxes for electrical components in industries such as high-speed rail and new energy vehicles.

The equipment size can be customized according to customer needs; detailed solutions are provided according to different product specifications, and high-precision equipment is designed.

Liquid Cold Plate

A liquid cold plat is a heat exchanger that transfers heat from electronic components or batteries to a liquid coolant. It consists of a thermally conductive plate (aluminum or copper) with internal flow channels. Heat conducts from the heat source into the plate, then convects to the flowing coolant, which carries heat away to a remote radiator or heat exchanger. Cold plates achieve 10-50x better heat transfer than air cooling, enabling higher power densities and precise temperature control.

We can customize the liquid cold plat to your required specifications. Your custom labels can be printed on the liquid cold plat. Worldwide shipping, affordable prices. Send us your inquiry today!

Aluminum Brazing Flux

Aluminum Brazing Flux is a chemical aid specially formulated for the brazing of aluminum alloys. Its essential functions are to remove the tenacious surface oxide film on aluminum, prevent re-oxidation during brazing, and reduce the interfacial tension between the filler metal and the base material, thereby enabling the filler to spread and wet the surface so that a strong, sound joint can be formed.

We offer a high-tech potassium fluoroaluminate brazing additive, formulated with a variety of high-molecular surfactants in scientific proportions. It helps improve the appearance and color of brazed products and enhances their quality. Worldwide shipping, affordable prices!

Aluminum Microchannel Flat Tube

Microchannel aluminum flat tube (also known as “parallel flow aluminum flat tube or porous extruded tube”) is a thin-walled porous flat tubular material made of refined aluminum rods, through hot extrusion, and surface zinc spraying anti-corrosion treatment. Microchannel tubes are flat, rectangular and contain multiple channels. Since these channels have a higher surface area to volume ratio, they increase the heat transfer rate. Microchannel tubes are made in various sizes and aluminum alloys to ensure that they have the right characteristics for the application.

We have a large inventory of different types of microchannel tubes, including aluminum flat tubes for radiators, aluminum flat tubes for microchannel parallel flow, microchannel tubes for heat exchangers, aluminum flat tubes for microchannel condensers, and more. Worldwide shipping, affordable prices!

Radiator Header Plate

Widely used in automotive heat exchanger fins and top plates, they offer excellent characteristics such as lightweight, good thermal and electrical conductivity, and low cost. Worldwide shipping, affordable prices!

Radiator Stamping Die

We offer aluminum radiator header plate stamping dies achieving ±0.01mm precision with 300,000 to 1,000,000 cycle lifespan. Specifically designed for processing 4343/3003/7072 aluminum alloys (1.4-1.5mm thickness), ensuring leak-free performance under pressures exceeding 2.5 bar.

Ideal for Tier 1 automotive radiator manufacturers, heat exchanger producers, and aftermarket cooling system suppliers requiring IATF 16949 certified tooling solutions.

Radiator Plastic Tank

Plastic tank for auto radiator is a lightweight and durable water storage container used to hold coolant as it flows through the radiator. It usually adopts a “top-in, bottom-out” structure, which is responsible for the input and output of the coolant respectively. The water inlet chamber receives the high-temperature coolant, and the water outlet chamber guides the cooled coolant back to the engine circulation to regulate the engine temperature. Unlike traditional metal tanks, plastic tanks are widely used due to their cost-effectiveness, corrosion resistance, and ability to withstand high temperatures.

Our company has the ability to provide drawings, samples, design, and manufacturing. We welcome manufacturers and customers to customize based on samples.We welcome manufacturers and customers to customize based on samples.
