[Embodiments of the Invention]
Next, an embodiment of the subcooling system condenser according to the present invention will be described in detail with reference to the drawings. Fig. 1 is a front view of the condenser, Fig. 2 is a plan view of the same, Fig. 3(A) is a vertical cross-sectional view taken along line A-A in Fig. 1, Fig. 3(B) is a horizontal cross-sectional view taken along line L-L in Fig. 1, and Fig. 4 is a principle diagram showing the first and second condensers of the condenser in an expanded state.

このサブクールシステムコンデンサは、図１及び図２に示すように、共にマルチフロータイプである第一コンデンサ（１Ａ）と第二コンデンサ（１Ｂ）とを、互いの両側ヘッダーが垂直方向に沿う配置状態において、前後に重なった形で一体化したものである。
As shown in Figures 1 and 2, this subcooling system condenser is an integrated structure in which a first condenser (1A) and a second condenser (1B), both of which are multi-flow types, are stacked front to back with their headers aligned vertically.

しかして、第一コンデンサ（１Ａ）と第二コンデンサ（１Ｂ）の右側ヘッダー（12）（22）同士は、前後に重なって一体化した状態において、図３及び図４に示すように前者の流出口（８ａ）と後者の流入口（８ｂ）とが合致し、通孔（８）として連通している。これにより、第一コンデンサ（１Ａ）は全体が凝縮部（Ｃ）、第二コンデンサ（１Ｂ）の右側ヘッダー（22）がタンク部（Ｔ）、第二コンデンサ（１Ｂ）のコア部（10）がサブクール部（Ｓ）を構成している。
When the right-side headers (12) and (22) of the first condenser (1A) and the second condenser (1B) are stacked one on top of the other and integrated, the outlet (8a) of the former and the inlet (8b) of the latter coincide with each other and communicate with each other as the through-hole (8), as shown in Figures 3 and 4. As a result, the entire first condenser (1A) constitutes the condensation section (C), the right-side header (22) of the second condenser (1B) constitutes the tank section (T), and the core section (10) of the second condenser (1B) constitutes the subcooling section (S).

上記構成のサブクールシステムコンデンサにおいては、コンプレッサ（図示省略）より圧送される高温・高圧のガス冷媒は、第一コンデンサ（１Ａ）の冷媒入口（６ａ）から流入して凝縮部（Ｃ）をなすコア部（10）を複数本のチューブ（２）…を通して蛇行状に上方へ流れる過程で、該コア部（10）を紙面に垂直方向に流通する外気との熱交換によって効率く冷却・凝縮し、右側ヘッダー（12）の下部より通孔（８）を通ってタンク部（Ｔ）である第二コンデンサ（１Ｂ）の右側ヘッダー（22）内に気液混合状態で流入する。そして、該タンク部（Ｔ）では、未凝縮のガス冷媒が上部に溜まり、下部に溜まった液冷媒のみがサブクール部（Ｓ）をなすコア部（10）へ流入し、このサブクール部（Ｓ）を通過する過程で前記同様の外気との熱交換によって過冷却され、冷媒出口（６ｂ）から安定した低温の液冷媒として流出し、エバポレータ（図示省略）側へ導かれる。 In the subcooling system condenser of the above configuration, high-temperature, high-pressure gas refrigerant pumped by a compressor (not shown) flows through the refrigerant inlet (6a) of the first condenser (1A) and flows upward in a serpentine pattern through the core section (10) constituting the condenser section (C) through the multiple tubes (2). As the refrigerant flows upward, it is cooled and condensed efficiently by heat exchange with outside air flowing perpendicular to the plane of the drawing. The refrigerant then flows from the bottom of the right header (12) through the through-holes (8) into the right header (22) of the second condenser (1B), which serves as the tank section (T), in a gas-liquid mixed state. In the tank section (T), uncondensed gas refrigerant accumulates at the top, while only the liquid refrigerant accumulated at the bottom flows into the core section (10) constituting the subcooling section (S). As it passes through the subcooling section (S), it is subcooled by heat exchange with outside air in the same manner as described above, and flows out of the refrigerant outlet (6b) as a stable, low-temperature liquid refrigerant and directed to the evaporator (not shown).

Claims
