Abstract(J)	バッテリー電気自動車は航続距離を確保するためにバッテリー消費量を減らす必要がある．冬季は，外気から熱を吸収するヒートポンプシステムを使用し，暖房時の電池消費を抑えているが，外気の熱を吸収する際、熱交換器に発生する霜による効率低下の問題がある．今回，車両の排熱を利用した除霜を実現する熱輸送・除霜排水機能を有する熱交換器を開発したため，紹介する． Translation
Abstract(E)	Battery Electric Vehicle needs to reduce battery consumption to secure driving range. In winter, a Heat pump system which absorb heat from ambient air is used for reducing battery consumption in the cabin heating. However, it 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.

About search

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
