  • Patent number: 10837348
    Abstract: A thermal management device for a vehicle includes heat medium circuits, a reserve tank, and a connector. The heat medium circulates through the heat medium circuits separately. The reserve tank is configured to separate an air bubble contained in the heat medium from the heat medium. The connector allows the reserve tank to come in communication with the heat medium circuits selectively. As such, an occurrence of the heat loss in the degassing performed in the reserve tank can be suppressed with the thermal management device for a vehicle including the heat medium circuits.

  • Patent number: 10152096
    Abstract: A cooling liquid distribution device includes a storage tank, a liquid level detector and a liquid level displaying structure. The storage tank includes a first chamber for storing a cooling liquid. When a liquid level of the cooling liquid in the first chamber is detected by the liquid level detector, a liquid level detection result is generated. The liquid level displaying structure includes a second chamber, which is in fluid communication with the first chamber. Consequently, a liquid level of the cooling liquid in the second chamber is equal to the liquid level of the cooling liquid in the first chamber. The liquid level displaying structure is optically transmissible, and thus the liquid level of the cooling liquid in the second chamber is visible through the liquid level displaying structure. The storage amount of the cooling liquid can be realized by the user more easily.

  • Patent number: 9702633
    Abstract: An entrochemical energy transfer system and a related process for obtaining work from environmental thermal energy are disclosed. In one example, a plurality of linked entrochemical cells with nested chambers provides an aggregate thermal gradient of each entrochemical cell by transferring environmental thermal energy in and/or out of the plurality of linked entrochemical cells. The aggregate thermal gradient generated from the plurality of linked entrochemical cells can be utilized as an environmentally-friendly energy source for human needs. The entrochemical energy transfer system and the related process for obtaining work from environmental thermal energy utilize a set of entropy transfers from Earth's day and night thermal energy inflows and outflows. Furthermore, in one example, the process for obtaining work from environmental thermal energy involves two steps, each step resulting in entropic increases and transfers.
