図２〜図４に示すように、蓄冷材容器(15)は長手方向を上下方向に向けるとともに幅方向を通風方向に向けた略縦長方形の扁平中空状であり、蓄冷材容器(14)内に通風方向にのびる波頂部、通風方向にのびる波底部、および波頂部と波底部とを連結する連結部よりなるコルゲート状のアルミニウム製インナーフィン(18A)(18B)が配置されている。蓄冷材容器(15)は、両面にろう材層を有するアルミニウムブレージングシートにプレス加工が施されることにより形成され、かつ通風方向の両側縁部どうしが全長にわたってろう付された左右両構成板(19)と、両面にろう材層を有するアルミニウムブレージングシートにプレス加工が施されることにより形成され、かつ左右両構成板(19)の上下両端にろう付された両端閉鎖板(21)とよりなる。
As shown in FIGS. 2 to 4, the regenerator container (15) is a substantially vertical rectangular flat hollow shape whose longitudinal direction is directed in the vertical direction and the width direction is directed in the ventilation direction. Corrugated aluminum inner fins (18A) and (18B) each having a wave crest extending in the ventilation direction, a wave bottom extending in the ventilation direction, and a connecting portion connecting the wave crest and the wave bottom are disposed. The cold storage material container (15) is formed by pressing an aluminum brazing sheet having a brazing filler metal layer on both sides, and both right and left component plates in which both side edges in the ventilation direction are brazed over the entire length ( 19), and both end closing plates (21) formed by pressing an aluminum brazing sheet having a brazing material layer on both sides and brazed to both upper and lower ends of both left and right component plates (19). Become.
圧縮機の作動時には、冷媒流通管(12A)(12B)内を流れる冷媒の有する冷熱が、蓄冷材容器(15)の第１部分(22)の遮風凸部(29)の膨出端部、および第２部分(23)の凸部(32)の膨出端部を経て直接蓄冷材容器(15)内の蓄冷材に伝わるとともに、遮風凸部(29)および凸部(32)の膨出端部から第１部分(22)および第２部分(23)の左右両側壁とインナーフィン(18A)(18B)を経て蓄冷材容器(15)内の蓄冷材の全体に伝わって蓄冷材に冷熱が蓄えられる。さらに、圧縮機の作動時には、第１間隙(14A)に隣接する第２間隙(14B)の風上側を流れて冷却された後に第１間隙(14A)の第２通風路(27)内を流れる空気と、蓄冷材容器(15)の第２部分(23)内の蓄冷材との間で熱交換が行われるので、蓄冷性能および放冷性能を向上させることができる。
During the operation of the compressor, the cold heat of the refrigerant flowing in the refrigerant flow pipes (12A) (12B) is caused by the bulging end of the wind shield convex part (29) of the first part (22) of the cold storage material container (15). And is transmitted directly to the cold storage material in the cold storage material container (15) via the bulging end of the convex portion (32) of the second portion (23), and the wind shield convex portion (29) and the convex portion (32). The cold storage material is transmitted from the bulging end to the entire cold storage material in the cold storage material container (15) through the left and right side walls of the first portion (22) and the second portion (23) and the inner fins (18A) (18B). Cold energy is stored. Further, when the compressor is operated, it flows in the second ventilation path (27) of the first gap (14A) after cooling through the windward side of the second gap (14B) adjacent to the first gap (14A). Since heat exchange is performed between the air and the cool storage material in the second portion (23) of the cool storage material container (15), the cool storage performance and the cool discharge performance can be improved.
圧縮機の停止時には、蓄冷材容器(15)内の蓄冷材に蓄えられた冷熱が、蓄冷材容器(15)の第１部分(22)の遮風凸部(29)の膨出端部、および第２部分(23)の凸部(32)の膨出端部を経て冷媒流通管(12A)(12B)に伝わるとともに、インナーフィン(18A)(18B)と、第１部分(22)および第２部分(23)の左右両側壁と、遮風凸部(29)および凸部(32)の膨出端部を経て冷媒流通管(12A)(12B)に伝わり、さらに冷媒流通管(12A)(12B)を通過して第１間隙(14A)に隣接する第２間隙(14B)に配置されているアウターフィン(16)に伝わる。アウターフィン(16)に伝わった冷熱は、第２間隙(14B)を通過する空気に伝えられる。したがって、蓄冷機能付きエバポレータ(1)を通過した風の温度が上昇したとしても、当該風は冷却されるので、冷房能力の急激な低下が防止される。
When the compressor is stopped, the cold energy stored in the regenerator material in the regenerator container (15) is caused by the bulging end of the wind shield convex part (29) of the first part (22) of the regenerator container (15), And is transmitted to the refrigerant flow pipes (12A) and (12B) through the bulging end of the convex part (32) of the second part (23), the inner fins (18A) and (18B), and the first part (22) and It is transmitted to the refrigerant flow pipes (12A) and (12B) through the right and left side walls of the second portion (23) and the bulging end portions of the wind shield convex part (29) and the convex part (32), and further to the refrigerant flow pipe (12A ) (12B) is transmitted to the outer fin (16) disposed in the second gap (14B) adjacent to the first gap (14A). The cold heat transmitted to the outer fin (16) is transmitted to the air passing through the second gap (14B). Therefore, even if the temperature of the wind that has passed through the evaporator with a cold storage function (1) rises, the wind is cooled, so that a rapid decrease in cooling capacity is prevented.
