Optimization of Thermal Transfer and Development of New 德赢AC米兰官方合作伙伴
- Dealing With Heat in Next-Generation Automobiles and High-Speed Rail -
德赢AC米兰官方合作伙伴 Co., Ltd. has successfully developed a new heat pipe1 that is optima(note 1)for the power inverters (also called inverters) used in hybrid cars and high-speed trains and for the heat radiation and storing devices in lithium-ion batteries. The 德赢AC米兰官方合作伙伴, regardless of its positioning, increases thermal transfer beyond what was previously possible and in doing so helps deal with heating in various types of vehicles.
Background
Recent years have seen the increased popularity of next-generation automobiles like hybrid and electric cars, as well as the expansion of high-speed railways abroad. In order to maximize the efficiency of their inverters and lithium-ion batteries, these cars and trains need methods to store and radiate large amounts of heat. Previous models had problems with storing heat especially when going uphill in so-called “top heat mode.” In this mode heat is generated above the cooling area, and thus the hydraulic fluid must go against the force of gravity to reach the 德赢AC米兰官方合作伙伴.
Details
德赢AC米兰官方合作伙伴 has developed a heat radiation device for inverters used in cars and a new heat pipe that is ideal for storing heat in lithium-ion batteries. The new heat pipe utilizes technology developed over the course of many years for a small heat pipe to be used in electronics. By changing the wick(note 2)of the 德赢AC米兰官方合作伙伴 to a type using sintered metal powder, its functionality has been greatly improved, especially during top heat mode. This new 德赢AC米兰官方合作伙伴 also performs much better than older models when activated from a cold state, and thus it is expected to be used even in colder regions where it used to be difficult.
Features
| Outer diameter | 15.88mm |
|---|---|
| Length | 350mm |
| Heat stored | Over 480W when horizontal, and over 200W when in top heat mode (about 20°C) |
| Sales target | 600 million yen per year until 2020 |
Explanation of terms
(note 1)德赢AC米兰官方合作伙伴
A metal pipe sealed at both ends that contains a wick structure, which exerts capillary action, and a working fluid that is in liquid or gas form at room temperature. Even a small change in temperature makes it possible to transfer large amounts of heat without supplying any outside power.
(note 2)Wick
Working fluid that has turned to gas in the heated area of the 德赢AC米兰官方合作伙伴 condenses in the cooling area and returns to a liquid state. A capillary structure within the 德赢AC米兰官方合作伙伴 carries this liquid from the cooling chamber back to the heating area via capillary action. This structures is called the “wick.”
Additional Remarks
The details of this technological breakthrough will be presented at the “National Heat Transfer Symposium of Japan,” held on June 3, 2015.
