摘要： The invention relates to a cooling device for a machine tool (10) for cooling a heated fluid, for example a cooling lubricants, comprising at least one refrigerating unit (48) for a fluid which is filtered by a filtering unit (40) and is received form at least one storage tank (38) by means of a pumping unit provided with at least one hydraulic pump (P2), separated clean (22) and waste (36) tanks, wherein the refrigerating unit (48) returns the circulating cooled fluid to the clean tank (22). Since the hydraulic pump (P2) of the pumping unit supplies the fluid only filtered by the filtering unit (40) from the waste tank (36) to the clean tank (22) and another independent hydraulic pump (P5) continues to supply the fluid from the clean tank to the refrigerating unit (48) for a subsequent circulation, the base structure of a known refrigerating device can be preserved and possible pressure losses caused by the blinding of the filter of the filtering unit have no negative effects on the constantly maintained flow rates for the refrigerating unit.

摘要： The invention relates to a fluid cooling device embodied as a modular unit comprising a drive motor (10) driving a ventilation wheel (12) and a fluid pump (14) that supplies a first type of fluid into a fluid system, and leads to a heat exchanger (22) from which the fluid is redirected into the fluid system in a tempered manner. The inventive device also comprises a second fluid pump (32) which is used to extract a second type of fluid from the reservoir (30) and to supply the same to a second fluid system, from which the second type of liquid is redirected towards the reservoir (30) in a guiding manner via the first (22) and the second heat exchanger (24). Said second fluid pump enables different tempering operations to be carried out for separate fluid systems, using only one fluid cooling device.

摘要翻译：本发明涉及一种用于冷却加热流体（例如冷却润滑剂）的机床（10）的冷却装置，该冷却装置包括至少一个用于流体的冷却单元（48），该冷却单元由过滤单元（40）过滤并且通过设置有至少一个液压泵（P2），分离的清洁（22）和废物（36）罐的泵送单元从至少一个储罐（38）接收，其中所述制冷单元（48）使循环的冷却流体到清洁罐（22）。由于泵送单元的液压泵（P2）将仅由过滤单元（40）过滤的流体从废液箱（36）供应到清洁箱（22），并且另一独立液压泵（P5）继续供应流体从清洁罐到制冷单元（48）以进行后续循环，已知制冷设备的基础结构可以被保留，并且由过滤单元的过滤器的致盲所引起的可能的压力损失不会对持续维护产生负面影响制冷机组的流量。
