The arrangement is made up in part of nodes, each individually simulated, and at least some of the nodes communicate with each other by means of values which within the domain of the simulator are understood as currents but which may have real-world significance for some value that is not a current at all. The currents are passed on a (simulated) analog bus. Some lines on the analog bus, while understood as “currents” in the domain of the simulator, are actually values that merely pass messages between modeling elements, the “current” values not necessarily representing any real-life measurable such as the aforementioned temperature value.

The battery module has a first battery cell, a housing, and a first solid cooling fin. A first panel portion of the first solid cooling fin is disposed against the first battery cell. A second panel portion of the first solid cooling fin is disposed on an outer surface of the housing and is coupled to an end portion of the first panel portion. A first side of the thermoelectric heat pump is disposed against the second panel portion, and a second side of the thermoelectric heat pump is disposed against the cooling manifold. The thermoelectric heat pump transfers heat energy from the first solid cooling fin to the cooling manifold in response to a first electrical current flowing through the thermoelectric heat pump in a first direction, to reduce a temperature level of the first battery cell.

  • Patent number: 9553249
    Abstract: The invention relates to a method for producing a thermoelectric component or at least one semi-finished product of same, in which a multiplicity of thermolegs made of a thermoelectrically active material are introduced into an essentially planar substrate made of an electrically and thermally insulating substrate material such that the thermolegs extend through the substrate essentially perpendicular to the substrate plane, and in which the active material is provided in pulverulent form, is pressed to give green bodies and is then sintered within the substrate to give thermolegs. It is based on the object of refining the method of the generic type mentioned in the introduction so as to increase the freedom of choice of the thermally and electrically insulating substrate material.

  • Patent number: 9553158
    Abstract: Embodiments of the invention provide a conductive structure, a thin film transistor, an array substrate, and a display device. The conductive structure comprises a copper layer formed of copper or copper alloy; a blocking layer for preventing copper ions of the copper layer from diffusing outward; and a diffusion prevention layer for preventing exterior ions from diffusing to the copper layer and disposed between the copper layer and the blocking layer. The multilayer conductive structure according to an embodiment of the invention can prevent exterior ions from diffusing into a copper layer and prevent copper ions from diffusing outward to reduce ions diffusion that adversely impacts the electricity performance and chemical corrosion resistance of the copper metal layer, and meanwhile can enhance adhesiveness of the conductive structure, which may be helpful for etching/patterning of the multilayer conductive structure.

  • Patent number: 9537077
    Abstract: A thermoelectric device and method based on creating a structure of nanoclusters in a composite metal and insulator material by co-depositing the metal and insulator material and irradiating the composite material to create nanoclusters of metal within the composite material. In one variation, the composite material may be continuously deposited and concurrently irradiated. A further variation based on a multilayer structure having alternate layers of metal/material mixture. The alternate layers have differing metal content. The layer structure is irradiated with ionizing radiation to produce nanoclusters in the layers. The differing metal content serves to quench the nanoclusters to isolate nanoclusters along the radiation track. The result is a thermoelectric device with a high figure of merit. In one embodiment, the multilayer structure is fabricated and then irradiated with high energy radiation penetrating the entire layer structure.

  • Patent number: 9400127
    Abstract: Cryogenic electronics based upon semiconductive devices, superconductive devices, or a combination of the two present opportunities for a wide variety of novel, fast, and low power devices. However, such cryogenic electronics require cooling which is typically achieved through fluid refrigerants such as liquid nitrogen or liquid helium. Solid state refrigeration based upon adiabatic demagnetization in paramagnetic salts offers one alternative but requires that the solid state cooler and cryogenic electronic circuits be different physical elements. The inventors present solid state cooling for semiconductor materials including but not limited to silicon. Beneficially active electronic devices can be integrated monolithically with solid state semiconductor coolers exhibiting magnetic cooling within the whole substrate or predetermined regions of the substrate. Alternatively, active devices may be formed with semiconductor layers integral to them that exhibit magnetic cooling.
