2results about How to "Short cooling path" patented technology

The application provides a bearing seat, an electric spindle assembly and a numerical control machine tool. The bearing seat comprises an outer seat body, an inner seat body, a damping structure and a cooling channel. The outer seat body forms an outer chamber, and the inner seat body is arranged in the outer chamber. A damping cavity is formed between the inner seat body and the outer seat body, and the damping structure is arranged in the damping cavity. The cooling channel is formed in the outer seat body, the inner seat body or the damping structure. The cooling effect and the damping effect are considered, the damping structure improves the support damping between the inner seat body and the outer seat body, and the vibration between the inner seat body and the outer seat body can be absorbed. The cooling liquid is introduced into the cooling channel, the heat generated by the high-speed rotation of the bearing can be taken away, the thermal deformation of the bearing and the bearing seat is prevented, the rotation accuracy of the electric spindle and the stability of the electric spindle operation are improved. The damping structure is formed by injecting a hot-melt glue type material into the damping cavity and solidifying, and the pressure of the damping cavity is not adjustable. The damping structure is formed by injecting metal powder, silicon oil or hydraulic oil into the damping cavity, and the pressure of the damping cavity is adjustable.

This invention relates to the field of temperature-controlled clothing technology, solving the problem in existing technologies where the lack of an effective linkage control mechanism between thermoelectric elements and cooling fans affects the overall cooling effect. It provides a protective suit with temperature regulation function and its temperature control method. The protective suit includes: a garment body comprising an inner layer facing the body and an outer layer away from the body; a semiconductor refrigeration component disposed on the garment body; a power module electrically connected to and supplying power to the semiconductor refrigeration component; a cooling fan disposed on the outer layer of the garment body and electrically connected to the power module; and a control module for controlling the start / stop and power adjustment of the semiconductor refrigeration component and the cooling fan to achieve an adjustable cooling effect on the body.
