  • Patent number: 10845130
    Abstract: A heat exchange system for commercial kitchen installations, having a dedicated plenum to receive combustion emissions separate from cooking emissions, where the plenum has a heat exchange structure that efficiently and directly draws heat from the combustion emissions. The plenum heat exchange structure reduces the air volume that a ventilation hood covering the kitchen appliances needs to process and filter, while concurrently obtaining heat from combustion emissions without interference from cooking emission effluents such as grease, smoke, or particulate matter. Heat drawn out of the combustion emissions can be stored in a thermal reservoir for powering other parts of the commercial kitchen or other uses. The diverted airstream from combustion emissions, once passed through the heat exchange structure, can further ventilate through an additional heat exchanger, to provide tempered air to an interior location, such as the commercial kitchen via an air supply duct in the cooking emission ventilation hood.

  • Patent number: 10782052
    Abstract: A micro environmental control system that can remove or add 30W from or to the near range personal microenvironment of a user. For cooling, the ?X uses a micro vapor compression system during the un-occupied period to freeze a phase-change-material in a thermal storage module. A fan then moves air over the phase-change-material to deliver cooled air. Heating is delivered by a small electric heater integrated into a condensing unit. The resulting system is inexpensive to build and uses a limited amount of energy.

    Abstract: Disclosed herein is a device for housing a plurality of electrochemical cells, wherein the housing provides stability, temperature control and maximum packing density. The battery module housing comprises a first semi-enclosure and a second semi-enclosure, wherein the first and second semi-enclosure are aligned to form compartments there between. Each compartment is designed to accommodate at least one electrochemical cell, such as a cylindrical battery or a prismatic battery. Each semi-enclosure comprises an interior wall and an exterior wall. The interior and exterior wall align together to form a flow path between the walls through which coolant or any other thermal management medium may flow. The coolant enters the semi-enclosure through a coolant inlet, flows between the interior and exterior walls; then flows out of the semi-enclosure through a coolant outlet.

  • Publication number: 20150136370
    Abstract: In a small-sized fluid heat exchanging apparatus that heats or cools a huge amount of gas or liquid, a structure makes fluid having a high flow speed impinge perpendicularly against a wall. A flow passage is divided into a high-speed flow passage and a low-speed flow passage, and the high-speed flow passage and the low-speed flow passage are arranged so as to intersect perpendicularly with each other, according to guidelines for the shape of the flow passage. A flow passage designed according to the guidelines provides highly-efficient heat exchange.

  • Patent number: 9033030
    Abstract: An apparatus and method for minimizing cold spots on plates of a plate-type fluid-to-fluid heat exchanger averages the plate temperature at a hot-fluid exit plane of the heat exchanger. The heat exchanger matrix is constructed to internally vary the flow patterns of opposing hot and cold fluid streams so that the heat transfer coefficient values of one or both fluid streams, designated as h, are optimized so the hot fluid value is a greater value than that of a cold fluid value. Plate variable flow structures are arranged in a manner that allows higher velocity hot fluid flow and possible lower velocity cold fluid flow in areas where the plate temperatures are coolest and the opposite configuration where plate temperatures are hottest.

  • Patent number: 8985192
    Abstract: A plate fin heat exchanger of the present invention includes a heat exchange part including a heat exchange part main body including layers of plural flow passages, and heat transfer members each of which is disposed within each flow passage of the heat exchange part main body to transfer the heat of fluid flowing in each of the flow passages to each partition walls opposed across the flow passage; and sensing parts connected to both the outsides of the heat exchange part respectively. Each of the sensing parts includes plural sealed spaces, and a sensor wall disposed to separate the outermost sealed space from the sealed space on the inner side thereof. The plate fin heat exchanger further includes a detection means for detecting damage of the sensor wall of the sensing part. According to such a structure, external leak of the fluid performing the heat exchange can be prevented while suppressing deterioration of performance or increase in size or weight.

  • Publication number: 20140345312
    Abstract: A heat exchanger includes a refrigerant tube through which a refrigerant for absorbing heat from air flows, and a defrosting medium tube through which a coolant for supplying heat for defrosting flows. Two fins disposed on both sides of the refrigerant tube include a protrusion protruding toward an upstream side of the flow of air with respect to the refrigerant tube. The protrusion is provided with a clearance that allows melt water generated in the defrosting to flow on the upstream side of the refrigerant tube. The refrigerant tubes and the defrosting medium tubes can be alternately arranged in the upstream line. The protrusion protrudes such that the air can be introduced into an air passage from the side portion of the protrusion even when an end facing the upstream side of the flow of the air is closed with the core of frost.

  • Patent number: 8844610
    Abstract: The present invention is a plate heat exchanger that allows refrigerant to enter the heat exchanger simultaneously from two sides. Allowing the refrigerant or other fluid to enter from two sides splits the flow and improves fluid velocities by presenting an optimized area to the fluid flow. This effect may be realized for both gases and liquids, and for example with respect to a liquid refrigerant, where it enters the heat exchanger simultaneously by splitting. According to the present invention the split liquid flow from the condenser feeds dual electronically controlled expansion valves before entering the heat exchanger. Fully evaporated gas leaves the heat exchanger through a single outlet, or through a dual outlet.
