PROBLEM TO BE SOLVED: To provide a coolant cooling device that prevents sludge from being deposited on a heat exchanger of a coolant chiller and can save the time and effort for cleaning the heat exchanger.SOLUTION: A coolant cooling device 1 comprises a coolant liquid tank 31 that stores coolant liquid L, a coolant chiller 10 that comprises a heat exchanger 20 storing a cooler 15 that cools the coolant liquid L by a refrigeration cycle C, and a circulation pump 34, by which the coolant liquid L is supplied to the heat exchanger 20 to cool the coolant liquid L. In the coolant cooling device 1, an opening face 36e of a return pipe 36 for returning the coolant liquid L cooled by the heat exchanger 20 to the coolant liquid tank 31 is provided laterally. 【課題】クーラントチラーの熱交換器にスラッジが堆積することを防ぎ、熱交換器の洗浄の手間を減らすことができるクーラント冷却装置を提供する。【解決手段】クーラント液Ｌを貯留するクーラント液タンク３１と、冷凍サイクルＣによりクーラント液Ｌを冷却する冷却器１５を収納した熱交換器２０を備えるクーラントチラー１０と、循環ポンプ３４によってクーラント液Ｌを熱交換器２０に供給してクーラント液Ｌを冷却させるクーラント冷却装置１において、熱交換器２０によって冷却されたクーラント液Ｌをクーラント液タンク３１に戻す戻し管３６の開口面３６ｅを横向きに設けている。【選択図】図１
