Abstract(J)BEVは航続距離確保の為バッテリー消費抑制が必要.冬季車内暖房の省エネの為に少ない電力で大気熱をくみ上げるHPシステムが採用されている.HPシステムの課題として,大気から吸熱する熱交換器の着霜による効率悪化がある.今回,走行廃熱の除霜活用を実現する,熱輸送及び除霜・排水機能をもつ熱交換器を開発した.

Translation

Abstract(E)BEV needs to reduce battery consumption to secure driving range. in winter, an HP system which absorb heat from ambient air is used for reduce battery consumption in the cabin heating. However, HP has a problem of reduce efficiency due to frost formation of the heat exchanger that absorbs the heat of the ambient air. This time, we have developed a heat exchanger with heat transport and defrost drainage functions that realizes defrosting utilize waste heat of the vehicle.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
