Product Description

Product Description

U pipe solar collector is a kind of pressurized and efficient solar water heating device, heating flowing water or liquid in closed flow passage and U pipes with glass tubes, since the copper flow passage is welded with U pipe, water or liquid will never flow into glass tubes. U pipe collector is composed of three-target tubes, U pipe manifold and supporting bracket, and it is commonly used in active solar water heating system.
Working principle:

1. U pipe solar collector is special design to get higher efficiency than heat pipe solar collector .
2. U pipe welded together with main flow header. The fluid(water or anti-freezen liquid) is filled full inside U pipe and flow header. Directly nature circulation between U pipe and flow header enhance the efficiency largely.
3. Tubes absorb solar energy and transfer the heat energy directly by U pipe.

Types of system

How to choose the right system with the heat pipe solar collector?
There are two tyes of the system commonly.

The heat pipe  Solar Collector mainly works  wtih tank  for storage heating. There are two system: Passitive system   and Active system.
Passitive system we can call thermosyphone  hot water system,The heat pipe solar collector transfer the heat to tank by natural gravity. Fluid (water ,glycol ) from inlet is heated and become lighter density compare to non-heated fluid, this lighter density will go up to the outlet and heavier fluid will go down to inlet of collector . This thermosyphone priciple continue to happen until sun down . 

Our topic solar collector  thermosyphone  heater for your checking as below:


                                                                                                                                         


Active flat plate solar collector system : Differ from the termosphone system, the circulation is  not depends on nature gravity , it is actived by circulation pump . Pump works when the temperature difference achieve the setted valve, the heat will be exchanged between pressurized heat pipe  solar collector and storage tank . Tank can be with coil (one ,two or more coils)  as heat exchanger  for indirectly heat exchange or without coil for directly heat exchange.


Topic active flat plate solar collector system as below:
Split Pressurized heat pipe solar water heater system  with heat exchanger: Tank with copper coil(s) as heat exchanger ,system active with a workstation which combinated with circulation pump,controller, safety valve,pressure guage,expansion tank.


Split pressurized flat plate  solar heating system without heat exchanger: Tank designed without coil ,and no external heat exchanger is applied to system. System is drived by simple circulation pump and  a controller,if system is too big ,a expansion tank will be considered as pressure balance device.


Non-presurized heat pipe solar hot water system,compare to the pressurized system ,it is open loop system. Tank is non-pressurized with air vent ,so it is connected to the atmosphere. System runs without pressure. Because it is  economic , it is widely applied to big project. 

Our Advantages

Advantages of the heat pipe solar collector

1.heat pie solar collector devices can play as  high temerature source 
2.Heat pipe solar collector will be easy to maintain, even one tubes broken,it will not effect the whole system.
3.It is available for open and close loop freely.
4.Our manifold case can be aluminum and color or stainless steel ,can help customer to save the cost
