Ultra-Slim Flat Plate Collector

Ultra-thin flat plate collectors - Re-defining the integration of solar energy and architecture

I. Product Overview

In today's pursuit of the perfect integration of architectural aesthetics and energy efficiency, the bulky and conspicuous appearance of traditional solar collectors has become a major bottleneck hindering their widespread application. The ultra-thin flat plate collector has emerged, combining efficient solar thermal utilization technology with modern industrial design in a 50mm ultra-thin body, opening up new possibilities for integrated solar energy applications in buildings.

II. Product Introduction

The ultra-thin flat plate collector is composed of a transparent cover plate, an absorber plate, an insulation layer, and an outer shell. The entire machine is only 50mm thick, far thinner than the 80mm thickness of traditional flat plate collectors. The appearance adopts modern minimalist industrial design, with smooth and flowing lines, and can perfectly blend into various building facades and roofs.

The standard appearance size of the product is 2021×1021×50mm, with a solar light area of 1.9㎡. The frame is made of high-strength aluminum alloy profiles, featuring lightweight and structural strength. The surface is treated with metal polishing technology, presenting an outstanding texture and strong weather resistance. The front of the collector is equipped with ultra-white low-iron tempered glass, with a light transmittance of up to 94% ± 2%, maximizing the intake of solar light.

III. Working Principle

The working principle of the ultra-thin flat plate collector is based on light-to-heat conversion. Sunlight passes through the highly transparent glass cover plate and is projected onto the absorber plate surface. The blue film selective absorption coating on the absorber plate efficiently absorbs solar radiation energy and converts it into heat. The heat is transferred through the flow channels to the internal heat transfer medium (water or antifreeze), causing the medium temperature to rise, and is then output through the collector outlet for end uses such as domestic hot water and heating.

The mesh flow channel structure inside the collector significantly increases the contact area between the medium and the absorber plate, significantly enhancing absorption and heat exchange efficiency. At the same time, the polyurethane insulation layer at the bottom effectively prevents heat from dissipating downward, and the low-iron glass at the top reduces convective and radiative heat loss, forming a complete insulation system, ensuring efficient collection and retention of heat, even in cold climates.

V. Technical Advantages

1. Ultra-thin design, significantly reducing logistics costs

Traditional collectors are generally over 80mm thick, while the ultra-thin flat plate collector is only 50mm thick. Calculated based on a 40HQ standard container, traditional collectors can fit approximately 270 units per container, while the ultra-thin model can fit 400 units, saving 38% of transportation space. For large-scale projects, this means a significant reduction in logistics costs and a significant improvement in supply chain efficiency.

2. High insulation performance, locking in every bit of heat

Using 35kg/m³ high-density polyurethane, formed by a one-time high-pressure foaming process. The closed-cell ratio is over 97%, and the thermal conductivity is as low as λ=0.023 W/(m·K). The one-time molding process ensures a uniform and seamless insulation layer, forming a continuous and complete insulation barrier, minimizing heat loss and maintaining excellent thermal performance even in cold climates.

3. Blue film coating, outstanding light-to-heat conversion efficiency

The absorber plate is coated with an advanced PVD physical vapor deposition technology for blue film selective absorption coating. Under AM1.5 standard light conditions, the solar absorption rate α=95% ± 2%, and the emissivity is only 4% ± 2%. High absorption rate means capturing more solar energy, while low emissivity effectively reduces heat loss through radiation. The coating maintains an absorption performance of over 95% of the initial state after 25 years of use, with an extremely long service life.

4. Modern design, perfectly matching architectural aesthetics

The ultra-thin body can be installed closely against the roof or wall, no longer protruding conspicuously. The standard matte black surface can match most architectural styles, and can be customized with any RAL color number as needed. The square and flat shape of the product can be flexibly hung on the roof, wall, under the window, and on the balcony, truly achieving the integration of solar energy equipment and the building.

VI. Factory Advantages

The factory has an internationally leading intelligent flat collector assembly line, which realizes highly automated production. Intelligent assembly robots precisely control the entire manufacturing process, with excellent production efficiency. From raw materials to finished products, each collector undergoes strict quality inspection procedures to ensure consistency and reliability of the product. Core components offer a 10-year warranty, and the entire machine is guaranteed a 25-year service life.

VII. Application Scenarios

Domestic hot water and heating: Provide stable domestic hot water and winter heating guarantee for 3-5 person households. It is an ideal choice for villas, self-built houses, etc. of residential buildings.

1. Hotels, hospitals, office buildings: These densely populated places have a large and concentrated demand for hot water, and ultra-thin collectors can be flexibly combined to form a large system, with quick installation and stable operation.

2. Swimming pool constant temperature: Maintain a comfortable water temperature of 26-28℃ for private swimming pools or small commercial swimming pools, adapting to humid environments.

3. Industrial preheating: Meet the preheating requirements of materials or media in industrial production, adapting to complex on-site environments.

4. Public buildings: Can replace traditional glass curtain walls and be applied to stations, museums, shopping malls, etc., achieving the dual value of architectural aesthetics and energy output.
