  太阳能集热器是太阳能热水器的主要工作部件。它吸收太阳光并将其转化为热能。真空管型太阳能集热器按真空太阳能集热管的排列方式不同,可分为竖(真空太阳能集热管竖直排列)单排、横(真空太阳能集热管水平排列)单排和横双排三类。
Solar collector is the main working part of solar water heater. It absorbs sunlight and converts it into heat. According to the arrangement of vacuum solar collector, the vacuum tube solar collector can be divided into three types: vertical (vertical arrangement of vacuum solar collector) single row, horizontal (horizontal arrangement of vacuum solar collector) single row and horizontal double row.
以下为真空管型太阳能集热器的分类及特点:
The following are the classification and characteristics of vacuum tube solar collectors:
全玻璃真空管型太阳能集热器
All glass vacuum tube solar collector
基本组件:联箱、进水管、出水管、全玻璃真空太阳能集热管、尾架。
Basic components: header, water inlet pipe, water outlet pipe, all glass vacuum solar collector pipe, tailstock.
特点:工质在真空管内直排加热,非承压,抗机械冲击性能差,集热效率较高,热损小,防冻性能好,造价低,不易与建筑结合;内外热冲击时,存在炸管泄露的可能;适于强制循环形式、直流式和自然循环式系统。
Features: the working medium is directly heated in the vacuum tube, non pressure bearing, poor mechanical impact resistance, high heat collection efficiency, small heat loss, good antifreeze performance, low cost, not easy to be combined with the building; when the internal and external heat shock, there is the possibility of tube explosion leakage; suitable for forced circulation, direct current and natural circulation systems.
