  • Patent number: 11493283
    Abstract: A tube for use in a heat exchanger includes an upper portion, a base portion spaced from the upper portion, and a partitioning wall depending from the upper portion. The partitioning wall is bent away and spaced from the base portion in a first section of the tube to form a single flow channel within the tube along the first section. The partitioning wall contacts the base portion in a second section of the tube to form a partition separating a first flow channel from a second flow channel along the second section. The first section of the tube is configured for reception into an opening of a header tank of the heat exchanger.

  • Patent number: 11481851
    Abstract: A system for generating and applying a secure token in a resource distribution network is provided. For example, a headend system generates a time-based token based on a time duration specified for a meter. The time-based token indicates the time duration for the meter. The time-based token is further generated based on an identifier of the meter. The headend system transmits the time-based token to the meter via at least a mesh network. After receiving the time-based token, the meter validates the time-based token to determine that the time-based token is generated for the meter based on information related to the identifier of the meter. If the meter determines that the time-based token is valid, the meter connects premises associated with the meter to a resource distribution network for at least the time duration specified in the time-based token.

  • Patent number: 10371464
    Abstract: A tube header for a heat exchanger includes a header plate having two major dimensions defining a header plane. The header plate has a row of oblong passages extending through the header plate. Each passage is bordered by a ferrule monolithically formed with the header plate. The ferrule has a surrounding wall extending perpendicular to the header plane. A transitional area between the ferrule and the header plate has a reduced thickness that is smaller than the wall thickness of the ferrule. This transitional area provides a flexible hinge-like function for compensating dimensional changes during thermal cycles of a heat exchanger.

  • Patent number: 10317148
    Abstract: The heat exchanger has tubes and a header tank that is located at an end of the tubes in a longitudinal direction and communicates with the tubes. The header tank has a core plate that connects to the tubes and a tank body that is fixed to the core plate. The core plate has a tube connection surface, a sealing surface, and an inclined surface that connects the tube connection surface and the sealing surface with each other. A distance between the tube connection surface and an end surface of the tubes in the longitudinal direction is different from a distance between the sealing surface and the end surface in the longitudinal direction by disposing the inclined surface to incline with respect to the longitudinal direction. The tubes connect to the tube connection surface and the inclined surface in a condition of being inserted to the tube connection surface and the inclined surface.

  • Patent number: 10295167
    Abstract: Novel 3-D super-thermal conducting heat management design and delayed cooling using phase change materials are adopted to lower the temperature inside LEDs and other devices. The cooling mechanism uses a fin structure with hollow fins to dissipate heat to the environment. The hollow space inside the fins is connected to an interior chamber, where a liquid to vapor phase change material (L-V PCM) is provided to transfer heat from the LED chips to the surface of the hollow fins. The LED chips are mounted on an evaporator located at the bottom of the chamber. A liquid reservoir is provided, and the evaporator surface is hydrophilic with an additional wick structure to transport the L-V PCM liquid to the evaporator surface. The fins are parallel to each other and are either parallel or perpendicular to the evaporator surface. This structure has superior performance and is inexpensive to manufacture.
