Detailed Product Description

1.The above mentioned parameters are allowed to vary with the customer's demand.2.If there are some changes of the specifications or designs, no note will be given.There may be some differences between the picture and the material objective, and please take the material objective as.2) Major advantagesa) Simple structure:a heat collecting and conducting system could be formed just by aluminium swings, vacuum tube and a single heat pipe.b) High heat conducting efficiency: the diameter-altered cooling end is able to increase the heat loss area and heat conducting efficiency.c) No efficiency loss to heat transferring media, long service life: No cracks occur, because no non-condensate gas produced.d) Suitable for areas with a rather low temperature, for cracks could be avoided.
