  • Space Heater Guide
    ENERGY SAVINGTIPS SPACE HEATER GUIDE Heating your home with electric space heaters can easily double or triple your electric bill if you are not careful. Even though they are typically small in size, and often touted as 100% efficient, electric space heaters use a lot of electricity. Most space heaters use on average 1,500 Watts of electricity and cost about 15¢ an hour to operate. While that may not sound like much, it can add up quickly if heaters are left on for several hours a day. Leaving one space heater on for 8 hours a day for a period of one month could easily add an additional $30-$40 to your monthly electric bill. Following are some good tips to help manage your electric bill if you use electric space heaters in your home. Do not heat rooms that are not in use Space heaters should only be used in rooms you are occupying and should never be left unattended. Remembering to turn off heaters when you leave a room can help you save money on your electric bill. Use a thermometer to monitor room temperature Most space heaters do not have individual thermostats or temperature controls, and those that do are often inaccurate or hard to read. Use a separate room thermometer to accurately monitor room temperature and avoid overheating. Your central heating system may be a better choice If you are using multiple space heaters in your home for more than a few hours a day, it may be more efficient to use your central furnace for heating.

  • 3D Printed Aluminum Flat Heat Pipes with Micro Grooves for Efficient Thermal Management of High Power Leds
    www.nature.com/scientificreports OPEN 3D printed aluminum fat heat pipes with micro grooves for efcient thermal management of high power LEDs Chao Chang*, Zhaoyang Han, Xiaoyu He, Zongyu Wang & Yulong Ji* As the electronic technology becomes increasingly integrated and miniaturized, thermal management has become a major challenge for electronic device applications. A heat pipe is a highly efcient two-phase heat transfer device. Due to its simple structure, high thermal conductivity and good temperature uniformity, it has been used in many diferent industrial felds. A novel aluminum fat heat pipe, with micro-grooves, has in the present work been designed and fabricated by using a 3D printing technology. Aluminum powder was used as a raw material, which was selectively melted and solidifed to form the shape of the heat pipe. The sintered aluminum powder increased the roughness of the inner surface of the heat pipe, and the designed micro-grooves further enhanced the capillary forces induced by the wick structure. The wettability, for the working fuid (acetone), was excellent and the capillary forces were sufcient for the working fuid to fow back in the pipe. The efects of working fuid flling ratio, on the heat transfer performance of the heat pipe, was also investigated. It was shown that a flling ratio of 10% gave the best heat transfer performance with the lowest thermal resistance. The 3D-printed fat heat pipe was, therefore, also tested for the thermal management of a LED. The temperature of the LED could be kept within 40 °C and its service life became prolonged. With the rapid development of the microelectronic technology, and the growing need by the information indus- tries, the integration and miniaturization of electronic equipment have become a new development trend 1,2.

  • Putting It All Together: Infrared Heat and Ceramicx ENGINEERING COMPETENCIES PRODUCT GUIDE TYPES of HEATERS NEW BUILDING CERAMICX INFRARED for INDUSTRY
    HeatWorksHeatWorks 20 │ www.ceramicx.com Putting it all together: Infrared Heat and Ceramicx ENGINEERING COMPETENCIES PRODUCT GUIDE TYPES OF HEATERS NEW BUILDING CERAMICX INFRARED FOR INDUSTRY Welcome A fresh look at a new science A new factory certainly gives inspiration to take a fresh look at all manner of things. Such is the case here at Ceramicx and especially with regard to this the 20th issue of our in-house magazine – HeatWorks. We have chosen to celebrate our newly constructed facilities with a companion issue of the magazine – one that reminds, re-iterates and underscores the fundamentals of the science of Infrared heating. It is my hope that the reader retains this magazine issue as a regular primer and refresher on these IR heating matters. Four sections cover the ground; Principal types of IR heaters Primary Industrial Applications for IR heating Energy and radiation fundamentals Control and measurement of IR energy and heating. Make no mistake, Ceramicx is at the forefront of the scientific advancement of Infrared heating: Our commercial successes on five continents simply attest to the superior technical and scientific nature of our manufacturing and our resulting products and heaters. Empirical scientific research backs everything we do. And - as this magazine issue clearly shows - such IR science is not approximate. No ‘black art’ skills are required here. Instead, the clean, green and cost-effective energy solution for the C21 is becoming better understood and applied with every passing year. The new Ceramicx factory and enterprise remains at the cutting edge of that advancement. Frank Wilson Managing Director, Ceramicx Ltd.

It's shown that they're going to include the PDV. The mode of delivery may be in the place where the vibrating point is recognized as the mode of delivery. The best thing about the winter season is sipping a cup of hot coffee in the heat of your home. No? In this case, you pretty much need to consider having a portable heater or heater in the house. Why? Here are the reasons why portable heaters are a good choice to have in winter: When the central heating system is not enough to bite through the cooling weather. When you need to heat a room in a short period, when you only need a certain part of the house or room to heat up When you need to move the heater from one place to anotherFor all the reasons mentioned above, and many other, portable heaters are good to have. Decorate the heat around you while at home watching TV or in the office, with a portable heater. Depending on your specific needs and space constraints, you can choose among the many portable heaters available. In addition, a good portable heater will be powerful, but not noisy while working. Another important issue when choosing portable heaters is safety. We have compiled a list of the best portable heaters (compared to the aforementioned qualities). In addition, heaters are classified by different types, making it easy for you to choose the most suitable one.
