Abstract
Description
本願は、2021年1月25日に日本に出願された特願2021-009669号について優先権を主張し、その内容をここに援用する。
車両用空調装置100は、車両の内部(居室)に温度調節された送風を行うための装置である。図1に示すように、車両用空調装置100は、ファン1と、ファンケース2と、ダクト3と、エバポレータ4と、を備えている。
光照射ユニット90は、ダクト3内を流れる送風そのものや、ファン1、及びエバポレータ4に対して防カビ・防蝕を主な目的として殺菌処理を施すために設けられている。図2に示すように、光照射ユニット90は、ヒートシンク6と、電子基板5と、光照射素子7A,7Bと、パワー素子8と、を有している。
ヒートシンク6は、ヒートシンク本体61と、複数のフィン62と、を有している。ヒートシンク本体61は、ダクト3の内壁3Aに沿って広がる厚肉板状をなしている。ヒートシンク本体61はダクト3の内壁3Aに形成された開口部を介してダクト3の外部に一部が露出している。ヒートシンク本体61の厚さ方向における両面のうち、ダクト3の内部を臨む側の面は第一主面6Aとされている。この第一主面6A上には複数のフィン62が設けられている。フィン62は、第一主面6Aから当該第一主面6Aに直交する方向に突出するとともに、ダクト3内における送風の流れ方向(以下、第一方向Fとする。)に沿って延びる板状をなしている。また、これらフィン62は、第一方向Fに直交する方向に間隔をあけて配列されている。
上記した第一面5Aの両端部には、それぞれ光照射素子7A,7Bが設けられている。光照射素子7Aは、第一方向Fにおけるファン1側に位置している。光照射素子7Bは、第一方向Fにおけるエバポレータ4側に位置している。光照射素子7A,7Bは、それぞれ第一面5Aから突出する板状の支持板71と、この支持板71の表面に取り付けられた複数の素子本体72と、を有している。図2又は図3に示すように、支持板71の突出高さは、ヒートシンク6のフィン62の突出高さよりも低く設定されている。つまり、第一方向Fから見て、フィン62の先端部は支持板71の上方に突出している。これにより、フィン62における支持板71に遮られる面積が減少するため、ヒートシンク6としてより効率的に放熱を行うことが可能とされている。また、支持板71は、第一方向Fの両側からヒートシンク本体61に当接している。つまり、支持板71とヒートシンク本体61とは熱的に接続されている。なお、両者が熱的に接続されている限りにおいて、支持板71とヒートシンク本体61との間にわずかな隙間が形成されていてもよい。この場合、電子基板5を介して支持板71とヒートシンク本体61とが熱的に接続される。
次に、本実施形態に係る車両用空調装置100、及び光照射ユニット90の動作について説明する。車両用空調装置100を運転するに当たっては、まずファン1を駆動する。また、不図示のコンプレッサを駆動することで、エバポレータ4を含む冷媒回路を動作させる。これにより、ファン1からダクト3を経て導かれた外部の空気がエバポレータ4に接触して冷媒と熱交換を行う。その結果、温度調節された送風が車内に供給される。
