Solar Heat Pipe Collector

Are you facing no hot water in frigid winter? Or perhaps sky-high energy bills in summer? It may be time to rethink your solar heat-collection system. In sub-arctic zones, traditional vacuum-tube collectors often freeze or crack below –10 °C and cease to operate. Commercial users—hotels or educational campuses—experience surges in hot-water demand that surpass what conventional systems can deliver. Maintenance is another recurring challenge: leaks lead to system downtime and can cost upward of ¥10,000 per annum in losses.

The Heat Pipe Solar Collector addresses these issues with advanced solar-thermal engineering. At the heart of the system is a sealed heat pipe filled with a specially formulated fluid. Sunlight passes through the vacuum tube’s selective absorber coating, converting into heat. That heat vaporizes the fluid inside the heat pipe; vapor rises to the top condenser, transfers heat to the storage-tank water, condenses back into liquid, and returns to restart the cycle. This rapid, repeating loop enables quick startup, substantial heat yields, and dependable operation—even when one tube becomes non-functional, the overall system keeps running. This makes the heat-pipe collector ideal for hot-water systems, space-heating, and industrial pre-heating in both residential and commercial contexts.

Product Strengths at a Glance

• High Extraction of Solar Heat

Featuring a D-DOS selective absorption coating with solar absorbance of at least 95% and infra-red emission at or below 5%.

• Superior Heat Pipe Performance

Incorporates working fluid that vaporizes almost instantly under heat, climbs the pipe, and releases heat vigorously at the condenser. Startup is rapid and energy losses are extremely small—thus the system collects even weak sunlight effectively.

• Built for Extreme Climates

Designed to thrive in ultra-cold conditions: the heat pipe starts at temperatures ≤ 30 °C, sustains operation at –25 °C with no freeze damage, and remains viable down to –50 °C. On overcast days it still captures diffuse solar energy reliably—avoiding the typical “shutdown” risk of older solar-thermal units.

• Robust Mechanical Design

Durable glass tubes withstand hail up to 25 mm in diameter; structural elements reduce wind-load impact and enhance system integrity.

• Safety & Maintenance Advantage

No direct contact between collector tubes and manifold eliminates leakage risk; replacement of a single tube doesn’t stop the system. The condenser end avoids scaling, extending lifespan and reducing maintenance cost.

• Flexible Mounting for Modern Buildings

Installation is unrestricted by tilt angle; tubes can be mounted horizontally, vertically or tilted, adapting seamlessly to diverse roof types and architectural façades for integrated aesthetics.

How It Works

• Light to Heat – Solar rays enter the high-transmittance glass (≥ 0.89) and are absorbed by the selective layer, turning into thermal energy.

• Phase-Change Transfer – Heat transfers via aluminium fins to the heat-pipe evaporator; the working fluid vaporizes and ascends.

• Heat Exchange – At the condenser, the vapor releases heat through a conductive block into the connected heating medium (water, oil, etc.).

• Cycle Reset – The fluid condenses and returns by gravity to the evaporator, enabling the loop to resume and transmit heat continuously.

Where It’s Used

• Residential hot-water and swimming-pool heating installations

• Space-heating systems for homes, hotels, hospitals and schools

• Industrial hot-water usage, pre-heating for processes, agricultural heating for farms and livestock
