And an evaporation section having a plurality of flat refrigerant flow pipe sections whose both ends are respectively connected to both refrigerant header sections, and fixedly provided on one surface of the refrigerant flow pipe section of the evaporation section. And a hollow regenerator in which a regenerator material is enclosed, and a set of a refrigerant circulation pipe part and a regenerator is provided at intervals in the length direction of the header part and adjacent to each other.

蓄冷機能付きエバポレータ(1)は、コンプレッサおよび冷媒冷却器としてのコンデンサとともに、フロン系冷媒を使用する冷凍サイクルを構成し、カーエアコンとして車両、たとえば自動車に搭載される。 The evaporator (1) with a cold storage function constitutes a refrigeration cycle using a chlorofluorocarbon refrigerant together with a compressor and a condenser as a refrigerant cooler, and is mounted on a vehicle, for example, an automobile, as a car air conditioner.
上述した蓄冷機能付きエバポレータ(1)においては、コンプレッサのオン時には、図６に示すように、コンプレッサ、コンデンサおよび膨張弁を通過した気液混相の２相冷媒が、冷媒入口(12)から第１タンク(2)の冷媒用ヘッダ部(7)の入口部(7a)内に入り、分流して右側の扁平中空体(4)の冷媒流通管部(23)内に流入し、冷媒流通管部(23)内を下方に流れて第２タンク(3)の冷媒用ヘッダ部(14)内に入る。第２タンク(3)の冷媒用ヘッダ部(14)内に入った冷媒は、左方に流れ、分流して左側の扁平中空体(4)の冷媒流通管部(23)内に流入し、冷媒流通管部(23)内を上方に流れて第１タンク(2)の冷媒用ヘッダ部(7)の出口部(7b)内に入り、冷媒出口(13)を通って流出する。 In the evaporator (1) with the cold storage function described above, when the compressor is turned on, as shown in FIG. 6, the gas-liquid mixed phase two-phase refrigerant that has passed through the compressor, the condenser, and the expansion valve is supplied from the refrigerant inlet (12) to the first phase. The refrigerant flows into the inlet (7a) of the refrigerant header (7) of the tank (2), flows into the refrigerant distribution pipe (23) of the right flat hollow body (4), and flows into the refrigerant distribution pipe. (23) Flows downward through the refrigerant header portion (14) of the second tank (3). The refrigerant that has entered the refrigerant header section (14) of the second tank (3) flows to the left, divides and flows into the refrigerant distribution pipe section (23) of the left flat hollow body (4), The refrigerant flows through the refrigerant flow pipe part (23) upward, enters the outlet part (7b) of the refrigerant header part (7) of the first tank (2), and flows out through the refrigerant outlet (13).
そして、冷媒が扁平中空体(4)の冷媒流通管部(23)内を流れる間に、隣り合う扁平中空体(4)間の通風間隙を通過する空気と熱交換をし、冷媒は気相となって流出する。 While the refrigerant flows in the refrigerant flow pipe portion (23) of the flat hollow body (4), heat exchange is performed with the air passing through the ventilation gap between the adjacent flat hollow bodies (4). And leaked.
このとき、扁平中空体(4)の冷媒流通管部(23)を流れる低温の冷媒の有する冷熱が、仕切板(29)およびアウターフィン(5)を介して蓄冷材封入管部(24)内に封入された蓄冷材に伝えられ、その結果蓄冷材が冷却されて凝固し、冷熱が蓄えられる。 At this time, the cold heat of the low-temperature refrigerant flowing through the refrigerant flow pipe part (23) of the flat hollow body (4) is transferred to the regenerator material-filled pipe part (24) via the partition plate (29) and the outer fin (5). Is transmitted to the regenerator material enclosed in the refrigeration material. As a result, the regenerator material is cooled and solidified, and cold energy is stored.
圧縮機が停止した場合には、蓄冷材封入管部(24)内の蓄冷材の有する冷熱が、アウターフィン(5)を介して隣り合う扁平中空体(4)間を通過する風に伝えられる。したがって、圧縮機が停止した場合においても、冷房能力の急激な低下が防止される。 When the compressor stops, the cold heat of the regenerator material in the regenerator material enclosing tube (24) is transmitted to the wind passing between the adjacent flat hollow bodies (4) via the outer fin (5). . Therefore, even when the compressor is stopped, a rapid decrease in the cooling capacity is prevented.

蓄冷機能付きエバポレータ(50)は、コンプレッサおよび冷媒冷却器としてのコンデンサとともに、フロン系冷媒を使用する冷凍サイクルを構成し、カーエアコンとして車両、たとえば自動車に搭載される。 The evaporator (50) with a cold storage function constitutes a refrigeration cycle using a chlorofluorocarbon refrigerant together with a compressor and a condenser as a refrigerant cooler, and is mounted on a vehicle, for example, an automobile, as a car air conditioner.
上述したエバポレータ(50)においては、コンプレッサのオン時には、実施形態１の蓄冷機能付きエバポレータ(1)の場合と同様に、コンプレッサ、コンデンサおよび膨張弁を通過した気液混相の２相冷媒が、冷媒入口(57)から上側冷媒用ヘッダ部(51)の入口部(51a)内に入り、分流して右側の扁平中空体(55)の冷媒流通管部(61)内に流入し、冷媒流通管部(61)内を下方に流れて下側冷媒用ヘッダ部(53)内に入る。下側冷媒用ヘッダ部(53)内に入った冷媒は、左方に流れ、分流して左側の扁平中空体(55)の冷媒流通管部(61)内に流入し、冷媒流通管部(61)内を上方に流れて上側冷媒用ヘッダ部(51)の出口部(51b)内に入り、冷媒出口(58)を通って流出する。 In the evaporator (50) described above, when the compressor is turned on, the gas-liquid mixed phase two-phase refrigerant that has passed through the compressor, the condenser, and the expansion valve is the refrigerant as in the case of the evaporator (1) with a cold storage function of the first embodiment. From the inlet (57), the refrigerant enters the inlet part (51a) of the upper refrigerant header part (51), flows into the refrigerant distribution pipe part (61) of the right flat hollow body (55), and flows into the refrigerant distribution pipe. It flows downward in the part (61) and enters the lower refrigerant header part (53). The refrigerant that has entered the lower refrigerant header section (53) flows to the left, splits, flows into the refrigerant distribution pipe section (61) of the left flat hollow body (55), and flows into the refrigerant distribution pipe section ( 61) flows upward in the upper refrigerant header portion (51), enters the outlet portion (51b), and flows out through the refrigerant outlet (58).
そして、冷媒が扁平中空体(55)の冷媒流通管部(61)内を流れる間に、隣り合う扁平中空体(55)間の通風間隙を通過する空気と熱交換をし、冷媒は気相となって流出する。 While the refrigerant flows in the refrigerant flow pipe portion (61) of the flat hollow body (55), heat exchange is performed with the air passing through the ventilation gap between the adjacent flat hollow bodies (55), and the refrigerant is in the gas phase. And leaked.
このとき、扁平中空体(55)の冷媒流通管部(61)を流れる低温の冷媒の有する冷熱が、仕切板(76)およびアウターフィン(92)を介して蓄冷材封入管部(62)内に封入された蓄冷材に伝えられ、その結果蓄冷材が冷却されて凝固し、冷熱が蓄えられる。 At this time, the cold heat of the low-temperature refrigerant flowing through the refrigerant flow pipe portion (61) of the flat hollow body (55) is transferred into the regenerator material enclosed pipe portion (62) via the partition plate (76) and the outer fin (92). Is transmitted to the regenerator material enclosed in the refrigeration material. As a result, the regenerator material is cooled and solidified, and cold energy is stored.
圧縮機が停止した場合には、蓄冷材封入管部(62)内の蓄冷材の有する冷熱が、アウターフィン(92)を介して隣り合う扁平中空体(55)間を通過する風に伝えられる。したがって、圧縮機が停止した場合においても、冷房能力の急激な低下が防止される。 When the compressor is stopped, the cold heat of the regenerator material in the regenerator material enclosing tube part (62) is transmitted to the wind passing between the adjacent flat hollow bodies (55) via the outer fins (92). . Therefore, even when the compressor is stopped, a rapid decrease in the cooling capacity is prevented.
上記２つの実施形態においては、上側の冷媒用ヘッダ部が後側に設けられるとともに下側の冷媒用ヘッダ部が前側に設けられ、さらに上側の蓄冷材用ヘッダ部が前側に設けられるとともに下側の蓄冷材用ヘッダ部が後側に設けられているが、これに限定されるものではなく、たとえば上下両冷媒用ヘッダ部が後側に設けられるとともに、上下両蓄冷材用ヘッダ部が前側に設けられていてもよい。 In the above two embodiments, the upper refrigerant header portion is provided on the rear side, the lower refrigerant header portion is provided on the front side, and the upper cool storage material header portion is provided on the front side and the lower side. However, the present invention is not limited to this. For example, the upper and lower refrigerant header portions are provided on the rear side, and the upper and lower regenerator header portions are provided on the front side. It may be provided.
