Laser Welded Leak Proof Connection Heater Core Tubing relies on precision laser welding, with dense welds, resistance to pressure, cold and hot alternation, and low leakage risk. It is the core pipe fitting of building HVAC heat exchange equipment, and its main application scenarios are as follows:
1. Central air conditioning fresh air and air handling unit (AHU)
Heating coils used in air handling units of large public buildings such as office buildings, shopping malls, hotels, hospitals, etc., to preheat and reheat winter fresh air. The building ventilation system has frequent cold and hot cycles, with repeated changes in pipeline temperature and pressure. Laser welding joints have strong stability, reducing the risk of ceiling water immersion and equipment damage caused by weld leakage, and ensuring the stable operation of fresh air heating in the building throughout the year.
2. Fan coil unit (FCU) heat exchange core
Internal heat exchange core tubes for indoor fan coil units in hotel rooms, office buildings, and apartments. These types of devices are scattered and installed in the ceiling of the room, and once they leak, it is easy to cause damage to the decoration and circuits. The connection position of laser welding has good sealing performance, and is less prone to medium leakage under long-term start stop conditions, reducing later maintenance and customer complaints.
3. Building centralized heating, plate radiator matching heat exchange pipe fittings
The internal core pipe of the centralized heating radiator in residential communities and commercial complexes is compatible with hot water heating medium. The heating system undergoes thermal expansion and contraction during heating and cooling every year, and ordinary welded joints are prone to micro cracks. This pipe fitting has high weld strength and can withstand periodic temperature shocks, making it suitable for buried and concealed heating equipment and reducing the workload of later maintenance.
4. Floor heating auxiliary heating and low-temperature radiation heating heat exchange components
Low temperature radiation heating supporting heat exchange units for large buildings and northern residential buildings, with some projects using heat pump systems. Most underfloor heating pipelines are buried in the ground structural layer, making maintenance difficult. The leak proof feature can prevent water seepage at the buried location and protect the ground decorative layer and civil structure.
5. Building waste heat recovery and ventilation energy recovery device
Core pipes for exhaust waste heat recovery equipment in large venues, underground garages, and large factories. Recovering indoor exhaust heat and preheating outdoor fresh air to achieve building energy efficiency. The equipment operates continuously throughout the year, and the pipe fittings are temperature and pressure resistant. The welds are not easy to fail, which helps to save energy and reduce consumption in buildings, and meets the energy-saving indicators of green buildings.
6. Integrated heating and heat exchange system for solar powered buildings
The solar energy collection system on building roofs is equipped with heat exchange core tubes, and the temperature difference of the solar energy system fluctuates greatly, resulting in unstable medium circulation pressure. Laser welding joints can withstand frequent hot and cold alternation, ensuring stable delivery of solar heat sources to the indoor heating end.
7. Temperature controlled dehumidification equipment for underground buildings and civil air defense projects
Constant temperature dehumidification units for underground garages, civil air defense basements, and underground utility tunnels. The underground environment has high humidity, and the pipe joints are corrosion-resistant and have reliable sealing to prevent leakage of heat exchange medium and corrosion of civil structures, maintaining stable temperature and humidity in the underground space.
8. HVAC renovation project for old buildings
Upgrade and replace HVAC systems in old residential areas and office buildings. The original old heat exchange pipe fittings have aging welds that are prone to leakage. After replacing this core tube, it is adapted to the original pipeline conditions, reducing the risk of water leakage after renovation and lowering maintenance costs in the later stage.
