以下に、本発明の車両用放熱器の搭載構造を図１〜図４を参照して説明する。   Below, the mounting structure of the vehicle heat radiator of this invention is demonstrated with reference to FIGS.

図１に示すように、本発明の車両用放熱器の搭載構造１０は、冷却風の流れ２０に対して直列に（車両前後方向に直列に）放熱器１１、１２を配置した車両用放熱器の搭載構造である。放熱器１１が上流側放熱器であり、放熱器１２が、放熱器１１の下流に配置された下流側放熱器である。放熱器１１、１２は互いに並列配置である。   As shown in FIG. 1, a mounting structure 10 for a vehicle radiator according to the present invention includes a vehicle radiator in which radiators 11 and 12 are arranged in series with a cooling air flow 20 (in series in the vehicle longitudinal direction). This is a mounting structure. The radiator 11 is an upstream radiator, and the radiator 12 is a downstream radiator disposed downstream of the radiator 11. The radiators 11 and 12 are arranged in parallel with each other.

上流側の放熱器１１のうち一部の部分１１ａは、冷媒がバイパス可能に構成してある。放熱器１１の放熱部位を可変とするために、上流側の放熱器１１の冷媒配管１５に、バイパス配管１６とバルブ１７を設ける。バイパス配管１６は、冷媒配管１５の、冷媒流れ方向に放熱器１１より上流側の部分と放熱器１１自体の途中部分とを連通する。バルブ１７は、冷媒がバイパス配管１６を通って流れる場合と、バイパス配管１６を通らずに配管１８を通って直接放熱器１１に流入する場合とを、切り替える。バルブ１７は、冷媒配管１５を流れる冷媒の全量を切り替えるオンオフバルブであってもよいし、あるいは冷媒配管１５を流れる冷媒の一部を切り替える流量制御弁であってもよい。   A part 11a of the upstream radiator 11 is configured such that the refrigerant can be bypassed. In order to make the heat radiation part of the radiator 11 variable, a bypass pipe 16 and a valve 17 are provided in the refrigerant pipe 15 of the upstream radiator 11. The bypass pipe 16 communicates the part of the refrigerant pipe 15 upstream of the radiator 11 in the refrigerant flow direction and the middle part of the radiator 11 itself. The valve 17 switches between a case where the refrigerant flows through the bypass pipe 16 and a case where the refrigerant flows directly into the radiator 11 through the pipe 18 without passing through the bypass pipe 16. The valve 17 may be an on / off valve that switches the entire amount of the refrigerant flowing through the refrigerant pipe 15, or may be a flow rate control valve that switches a part of the refrigerant flowing through the refrigerant pipe 15.

下流側放熱器１２は互いに異なる複数の冷却システムの放熱器部分１３、１４を含んでいる。
図示例では放熱器部分１４が放熱器部分１３の下方に配置されているが、これとは逆に、放熱器部分１４が放熱器部分１３の上方に配置されてもよいし、あるいは、放熱器部分１４が放熱器部分１３の横に配置されてもよい。放熱器部分１３、１４は、冷却風流れ方向に見て、互いに重ならないように配置される。
上流側放熱器１１のうち冷媒がバイパス可能な部分１１ａと、下流側放熱器１２の複数の冷却システムの放熱器部分１３、１４のうち強い冷却が要求される冷却システムの放熱器部分１４とが、冷却風流れ方向に（車両前後方向に）対応している。 The downstream radiator 12 includes a plurality of cooling system radiator portions 13, 14 that are different from one another.
In the illustrated example, the radiator portion 14 is disposed below the radiator portion 13, but conversely, the radiator portion 14 may be disposed above the radiator portion 13, or alternatively, the radiator The portion 14 may be disposed beside the radiator portion 13. The radiator portions 13 and 14 are arranged so as not to overlap each other when viewed in the cooling air flow direction.
A portion 11a of the upstream radiator 11 through which the refrigerant can be bypassed and a radiator portion 14 of the cooling system that requires strong cooling among the radiator portions 13 and 14 of the plurality of cooling systems of the downstream radiator 12 This corresponds to the cooling air flow direction (vehicle longitudinal direction).

図示例では、車両がハイブリッド車であり、上流側の放熱器１１が空調装置用コンデンサであり、下流側放熱器１２の複数の冷却システムの放熱器部分１３、１４がエンジンラジエータ１３と電気機器ラジエータ（「ＨＶラジエータ」ともいう）１４であり、強い冷却が要求される冷却システムの放熱器部分１４が電気機器ラジエータ１４である。
エアコンコンデンサ１１のうちバイパス可能な部分１１ａと電気機器ラジエータ１４とが車両前後方向に互いに対応するように配置される。また、エアコンコンデンサ１１のうちバイパス可能な部分１１ａ以外の部分とエンジンラジエータ１３とが車両前後方向に互いに対応するように配置される。
ハイブリッド車の場合、コンデンサ１１とＨＶラジエータ１４が要求する最大能力は同期しない。また、ＨＶラジエータ１４が最大能力を要求する頻度は、少ない。 In the illustrated example, the vehicle is a hybrid vehicle, the upstream radiator 11 is an air conditioner condenser, and the radiator portions 13 and 14 of the plurality of cooling systems of the downstream radiator 12 are an engine radiator 13 and an electrical equipment radiator. (Also referred to as “HV radiator”) 14, and the radiator portion 14 of the cooling system that requires strong cooling is the electrical equipment radiator 14.
The bypassable portion 11a of the air conditioner capacitor 11 and the electric equipment radiator 14 are arranged so as to correspond to each other in the vehicle longitudinal direction. Further, parts of the air conditioner condenser 11 other than the bypassable part 11a and the engine radiator 13 are arranged so as to correspond to each other in the vehicle longitudinal direction.
In the case of a hybrid vehicle, the maximum capacity required by the capacitor 11 and the HV radiator 14 is not synchronized. The frequency with which the HV radiator 14 requests the maximum capacity is low.

つぎに、本発明の車両用放熱器の搭載構造１０の作用・効果を説明する。   Next, functions and effects of the vehicle radiator mounting structure 10 of the present invention will be described.

ＨＶラジエータ１４の冷却条件が厳しい時（電気機器が強い冷却を要求している時）には、図２に示すように、バルブ１７を、エアコン冷媒がバイパス配管１６を通ってコンデンサ１１の途中部位からコンデンサ１１に流入するように切替え、放熱器１１のうち一部の部分１１ａにはエアコン冷媒が流れないようにする。これによって、冷却風が放熱器１１の一部の部分１１ａで温められずに、冷風のまま、強い冷却が要求される冷却システムの放熱器部分１４であるＨＶラジエータ１４に流れ、ＨＶ水温を効果的に低下させ、ＨＶ冷却システムを強く冷却することができる。この時は、エアコンの冷房能力は、部分１１ａを流れない分、低下し、かつ、コンプレッサの動力は多く必要であるが、電気機器が強い冷却を要求する頻度は少なく、かつコンデンサの最大能力時と同期しないので、冷房上、とくに問題となることはない。   When the cooling conditions of the HV radiator 14 are severe (when the electric equipment requires strong cooling), as shown in FIG. 2, the air conditioner refrigerant passes through the bypass pipe 16 and the intermediate portion of the capacitor 11 as shown in FIG. So that the air conditioner refrigerant does not flow through a part 11a of the radiator 11. As a result, the cooling air is not heated by the partial portion 11a of the radiator 11, but flows into the HV radiator 14, which is the radiator portion 14 of the cooling system that requires strong cooling, as the cold air, and the HV water temperature is effective. The HV cooling system can be cooled strongly. At this time, the cooling capacity of the air conditioner is reduced by the amount that does not flow through the portion 11a, and more power is required for the compressor, but the electric equipment is less frequently required for strong cooling, and the maximum capacity of the condenser. Because it does not synchronize with the air conditioning, there is no particular problem in cooling.

ＨＶラジエータ１４の冷却条件が厳しくない時（電気機器が強い冷却を要求しない時）には、図３に示すように、バルブ１７を、エアコン冷媒が配管１８を通ってコンデンサ１１の上流側端部から流入するように切替え、エアコン冷媒の全量が部分１１ａにも流れるようにする。これによって、冷却風は放熱器１１の一部の部分１１ａを冷却し冷却風自身は温度が上がって（約１０〜１５℃上がる）ＨＶラジエータ１４に流れる。このため、エアコンの冷房能力は上がり、かつ、エアコンコンプレッサの動力増加が抑制される。冷風温度の上昇分、ＨＶラジエータ１４での冷却性能は低下するが、ＨＶラジエータ１４の冷却条件が厳しくない時であるので、電気機器冷却上、問題となることはない。   When the cooling condition of the HV radiator 14 is not strict (when the electric equipment does not require strong cooling), as shown in FIG. So that the entire amount of the air-conditioning refrigerant flows also to the portion 11a. As a result, the cooling air cools a portion 11a of the radiator 11, and the cooling air itself rises in temperature (by about 10 to 15 ° C.) and flows to the HV radiator 14. For this reason, the cooling capacity of the air conditioner is increased, and an increase in power of the air conditioner compressor is suppressed. Although the cooling performance of the HV radiator 14 decreases due to the increase in the cold air temperature, there is no problem in cooling the electrical equipment because the cooling conditions of the HV radiator 14 are not severe.

ＨＶ水温とエアコン冷媒の流れの関係は図４に示す通りである。図４の（ｉ）がエアコン冷媒がバイパス配管１６を流れる場合であり、図４の（ii）がエアコン冷媒が配管１８を流れる場合である。バルブ１７の切替え水温は、（ｉ）から（ii）と、（ii）から（ｉ）への切替え温度を異ならせて、制御におけるハンチングを避けるようにする。
頻度は少ないが、ＨＶ水温（電気機器冷却システムの冷却水温）が上昇した場合は、エアコン冷媒はバイパス配管１６に流れ、ＨＶラジエータ１４には冷たい冷却風が導入され、ＨＶ水温を低下させる。
頻度の多いＨＶ水温低下中は、エアコン冷媒は配管１８に流れ、コンデンサ１１の放熱部位１１ａを利用し冷媒を冷却する。
その結果、コンデンサ１１の面積を縮小することなく、ＨＶ冷却性能が確保されるため、冷房性能を確保でき、コンプレッサの消費動力を低減し燃費向上をはかることができる。 The relationship between the HV water temperature and the flow of the air conditioner refrigerant is as shown in FIG. 4 (i) shows the case where the air conditioner refrigerant flows through the bypass pipe 16, and FIG. 4 (ii) shows the case where the air conditioner refrigerant flows through the pipe 18. The switching water temperature of the valve 17 is made different from the switching temperature from (i) to (ii) and from (ii) to (i) to avoid hunting in the control.
Although the frequency is low, when the HV water temperature (cooling water temperature of the electrical equipment cooling system) rises, the air-conditioner refrigerant flows into the bypass pipe 16 and cold cooling air is introduced into the HV radiator 14 to lower the HV water temperature.
During frequent HV water temperature decrease, the air conditioner refrigerant flows into the pipe 18 and cools the refrigerant using the heat radiation part 11a of the capacitor 11.
As a result, since the HV cooling performance is ensured without reducing the area of the capacitor 11, the cooling performance can be secured, the power consumption of the compressor can be reduced, and the fuel consumption can be improved.
