HYDRAULIC TEMPERATURE ADJUSTMENT UNIT

PROBLEM TO BE SOLVED: To provide a hydraulic temperature adjustment unit for supplying hot or cold fluid to a plurality of temperature adjustment devices to absorb an increased amount of volume of fluid at a less-expensive cost.SOLUTION: A hydraulic temperature adjustment unit 10 comprises a heat exchanger 20, a first supply passage 31, a first recovering passage 32, a second supply passage 33, and a second recovering passage 34 for connecting the heat exchanger 20 to a first supply port 11, a first recovering port 12, a second supply port 13, and a second recovering port 14, respectively, a first pump 41 and an expansion tank 45 arranged at the first recovering passage 32, a second pump 42 arranged at the second recovering passage, and a communicating pipe 38 for guiding a part of fluid flowing at the second recovering passage to the expansion tank 45. The communicating pipe 38 induces a higher pressure loss than at either of the first supply passage 31, the first recovering passage 32, the second supply passage 33, of the second recovering passage 34.SELECTED DRAWING: Figure 2 【課題】複数の温度調節機器に温熱または冷熱を供給する流体式温度調節ユニットにおいて、流体の体積増加分を吸収する機構を安価に実現すること。【解決手段】流体式温度調節ユニット１０は、熱交換器２０と、熱交換器２０を第１供給ポート１１、第１回収ポート１２、第２供給ポート１３、および２回収ポート１４にそれぞれ接続する第１供給路３１、第１回収路３２、第２供給路３３、および第２回収路３４と、第１回収路３２に設けられた第１ポンプ４１とおよび膨張タンク４５と、第２回収路に設けられた第２ポンプ４２と、第２回収路を流れる流体の一部を膨張タンク４５へと導く連通管３８と、を備える。連通管３８は、第１供給路３１、第１回収路３２、第２供給路３３、および第２回収路３４のいずれよりも、大きい圧力損失を誘発する。【選択図】図２
