What is heat pipe solar collector?
The heat pipe solar collector always connected with existing water heating device. The selective absorber coating on the inner cover of vacuum tubes absorb solar energy, then convert solar energy into thermal energy and transfer thermal energy to heat pipe by aluminum fin. The heated liquid inside heat pipe change into vapor which rises to the top condenser, then thermal energy heat transfer liquid pass through heat exchanger and the cooled vapor becomes liquid, returning to the base of heat pipe.
The thermal energy conducts to transfer liquid via a copper pipe. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.
Introduction to Vacuum Tube/Heat Pipe Solar Collector, Evacuated Tube Collectors
Vacuum Tube/Heat Pipe Solar Collector, Evacuated Tube Collectors works similar in design to a thermos. It consists of a two layers of glass with a vacuum in between the layers. The outer layer of the solar tube is Borosilicate glass which is very low in iron and allows 98% of light energy to pass through. The 2nd inner layer has very special coatings applied to it.
The Evacuated tube/Heat pipe solar collector consists of a number of rows of parallel transparent glass tubes connected to a header pipe and where the heat transfer fluid (usually 50% Propylene Glycol) circulates and absorb heat generated by tubes. These glass tubes are cylindrical in shape. Therefore, the angle of the sunlight is always perpendicular to the heat absorbing tubes which enables these collectors to perform well even when sunlight is low such as when it is early in the morning or late in the afternoon, or when shaded by clouds. Evacuated tube solar collector are particularly useful in areas with cold, cloudy wintry weathers (most of the northern part of the Europe).
Vacuum Tube/Evacuated Tube, Heat Pipe Solar Hot Water System
Vacuum Tube/Evacuated Tube/Heat Pipe Solar Collector Hot Water Systems are more efficient than flat-plate systems, particularly in the cooler months and on cloudy days. This is due partly to the vacuum insulation (which minimises heat loss) and partly to the fact that the curved surface of the tubes allows the sun’s rays to strike perpendicular to the water for a greater part of the day. Evacuated tube systems weigh much less than flat-plate systems but cost significantly more. Individual tubes can be replaced in the event of damage, making long term maintenance potentially less costly.. Properly maintained solar thermal collectors should outlast the life of the storage tank. When the tank needs replacing, the existing collectors can be connected to the new tank.
Temperature control heat pipe Solar collector
ONOSI Solar combines the patented five-dimensional heat transfer technology, uses self-developed working fluids and innovative technology, uses aerospace rare earth aluminum alloy materials as structural parts, and breakthroughs in the development of a new temperature-controlled heat pipe solar collector with super copper water heat pipes. The large-scale promotion of metal heat pipe vacuum tube solar collectors provides a revolutionary solution.
The most new innovation from ONOSI Solar is at the heart of the Heat pipe, we call it the Thermo Controlled Heat pipe. As the name suggests, a thermal temperature protection is integrated here. Unlike other mechanical protections, our protection is in the fluid that moves (flows) in the Heat pipe.
While the temperature in the traditional Heatpipe can easily rise to 250°C, the renewed Thermo Controlled Heatpipe stops at 110°C. As soon as this temperature is reached, the inside of the Heatpipe boils dry, so that the operation stops. In short, no protection in mechanical parts, but thermal in the core of the Heat pipe.

Intelligent temperature control
The ONOSI temperature control solar heat pipe has an intelligent temperature control function. The product intelligently senses the temperature change. The system stops immediately when the heat is excessive or gradually stops the heat transfer 110°C, and restores the performance immediately when the heat is not excessive. It fully meets the ideal temperature control requirements and realizes Precise temperature control; at the same time, the function of blocking at high temperature does not affect the heat transfer performance under normal working conditions. The maximum temperature of hot water in the solar system water tank can be controlled at 85°C.
Since 2001, 20+ Years Experience
ONOSI solar focus on the research and manufacturing of solar thermal products and is the founder of “intelligent temperature controlled heat pipe solar collectors”. The main products include: intelligent temperature controlled heat pipe solar collectors, intelligent temperature controlled solar water heaters, solar pool ionizers, etc.
The company fully implement ISO9001 international quality system authentication through on-site certification by authoritative organizations such as TUV , won the certification of SOLAR KEYMARK, SRCC, CE, ROHS，etc.
The company focus on product research and innovation, and has multiple patents. “Intelligent temperature control technology” is our core patented technology, industry initiate. It has a huge competitive advantage in the market where conventional heat pipe solar collectors are highly homogenized!
