Abstract: A housing device for a traction battery with fluid-based cooling in a vehicle. The traction battery has a plurality of a battery cells. The housing device includes a housing body, which forms an enclosed interior with a plurality of receiving positions for receiving the plurality of battery cells and a bottom region of which is designed to receive liquid fluid. An evaporation device is included for evaporating the liquid fluid. The evaporation device has a plurality of microchannel structures for forming microchannels. The microchannel structures extend in a vertical direction in the assembled state and have, in their lower region with respect to the vertical direction, at least one inlet opening for receiving liquid fluid from the bottom region of the housing body. During operation, liquid fluid enters the microchannels through the at least one inlet opening and heat is transferred from the battery cells to the liquid fluid in the microchannels. The liquid fluid evaporates in the evaporation device.

Abstract: A cooling device for cooling a traction battery of a vehicle by means of a fluid. The device includes an evaporation device for installing in a housing body of the traction body, at least one condensation device for installing on the vehicle outside of the housing body of the traction battery, and connection lines which conduct fluid evaporated in the evaporation device to the at least one condensation device and condensed fluid from the at least one condensation device back to the evaporation device. The evaporation device, the at least one condensation device, and the connection lines form a first cooling circuit. The first cooling circuit is designed in the form of a natural circulation.

Abstract: A coated spherical capsule that comprises a seamless capsule and an edible coating is disclosed. The seamless capsule includes a seamless solid shell surrounding a mononuclear liquid or viscous core and the edible coating surrounding the seamless capsule. The edible coating can include at least one dietary supplement and at least one sugar or sugar alcohol. The liquid or viscous core can include 1-100% of a flavoring, based on total weight of the liquid or viscous core. The edible coating can include an effective amount of the at least one dietary supplement based on the weight of the edible coating. Also disclosed is a method of administering an effective amount of a dietary supplement. The method includes providing a plurality of coated spherical capsule and ingesting at least one coated spherical capsule for two or more days in order to deliver an effective amount of a dietary supplement.
