2results about How to "Heat transfer" patented technology

This utility model relates to an energy storage battery pack optimized based on a battery management system, belonging to the technical field of energy storage battery packs. It includes a housing and a battery pack body disposed inside the housing. The inner side of the housing is provided with a heat dissipation assembly for cooling the battery pack. The heat dissipation assembly includes a partition fixedly connected between the top and bottom walls of the housing. A copper plate is fixedly connected to the left side of the partition, and heat dissipation fins are fixedly connected to the top of the copper plate. A water outlet valve is fixedly connected to the right side of the partition, and a water pump is fixedly connected to the right end of the water outlet valve. A spiral coil is fixedly connected to the outlet end of the water pump, and a connecting valve is fixedly connected to the outlet end of the spiral coil. This energy storage battery pack optimized based on a battery management system maximizes the contact area with the battery pack body by setting a spiral coil surrounding the battery pack body, with the spiral coil wall in contact with the battery pack body.

The utility model belongs to the technical field of building external wall panels, and particularly relates to a building external wall panel thermal insulation performance detection device. Comprising a bottom plate; the supporting plate is arranged around the top of the bottom plate; the top plate is arranged among the four supporting plates; the shell covers the top plate and other parts in the top plate; the protective door is arranged on the front side of the shell; the clamping plate assembly is used for clamping a wallboard on the heating unit; the clamping plate assembly comprises a guide rod arranged between two supporting plates on the same side; the sliding sleeves are slidably arranged at two ends of the guide rod; the connecting plate is arranged between the tops of the two transverse sliding sleeves; the supporting rods are arranged on the left and right sides of the connecting plate; the positioning plate is arranged between the two supporting rods on the same side; the power part is used for providing power to drive the connecting plates on the two sides to be close to or away from each other, so that the positioning plates clamp or loosen the wallboards. The utility model provides a device for detecting the thermal insulation performance of a building external wall panel, which can clamp and fix a wall panel so as to improve the accuracy of detection data.
