The present disclosure relates to a plate-type heat exchanger and a method for manufacturing same. A plate-type heat exchanger according to an embodiment of the present disclosure comprises a first plate and a second plate which have flange parts vertically adhered by an adhesive, respectively, wherein the flange parts are formed in a stepped shape and can thus increase the area adhered to the first plate and the second plate.

In one aspect, a tubular membrane assembly is provided for a heat exchanger. The tubular membrane assembly includes a header having a header body, a tubular membrane, and a fitting connecting the tubular membrane to the header body. The fitting is configured to form a fluid tight connection between the fitting and the tubular membrane. The tubular membrane assembly further includes potting of the header keeping the tubular membrane connected to the fitting.

Heat sinks containing polymeric protrusions on a base and optionally further including a foil or tape, as well as methods of making and using thereof, are described herein.

The invention relates to a manufacturing process for a heat dissipation heat sink composite having heat dissipation function and a manufacturing method for a finished product thereof. It comprises the steps of rolling a first heat conductive material and a substrate to adhere the first heat conductive material to the substrate for fixation; adhering a second heat conductive material to the substrate for combination; and rolling the second heat conductive material and the substrate for firmly combination and fixation to complete the manufacturing of a composite material.

A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels.

A heat spreading and insulating material using densified foam is provided that has a heat spreading layer that is adhered to an insulating layer. The material is designed to be used with mobile devices that generate heat adjacent to heat sensitive components. The insulating layer is formed from a compressed layer of polyimide foam to increase its density. The polyimide foam retains a significant amount of insulating properties through the densification process. In some embodiments, an EMI shielding layer is added to improve electrical properties of the device. The heat spreading layer may be a graphite material with heat conducting properties that preferentially conduct heat in-plane but can also be metal foil or other isotropic heat conducting material. The material may also include pressure sensitive layers to permanently apply the material to the mobile device.

A heat exchanger includes a roll-bond evaporator having a heatpipe channel network spanning a primary panel area and at least one secondary multiple panel area, and at least one plurality of fins joined to at least one secondary panel area. The primary panel area is configured to receive electronic circuitry, heat transfer fluid is evaporated in heatpipe channels of the primary panel area, the heat transfer fluid is condensed in heatpipe channels in the secondary panel area(s), and heat is dissipated by the fins into an ambient environment. Secondary panel areas may be bent to bound a cavity and/or assume a generally cylindrical shape. The heat exchanger may be incorporated into a small cell radio node for 5G telecommunications.

A cooling system for a photovoltaic panel including micro flat heat pipes (HP) integrated with thermoelectric generators (TEG) and a cooled water reservoir for cooling the working fluid in heat pipes. The cooled water in the reservoir is pumped from the condensate pan of an air conditioner. Experimental results show that cooling system reduced the average temperature of the panel by as much as 19 C. or 25%. Further, the output power of the photovoltaic panel increased by 44% when the photovoltaic panel was used in a very hot climate (30-40 C.). An additional two watts of power was generated by the TEGs.

A heat dissipation unit and a heat dissipation device using same are disclosed. The heat dissipation device includes a base and one or more heat dissipation units. The base has a first side and an opposite second side; and the heat dissipation units respectively include at least one radiation fin correspondingly provided on the first side of the base. The radiation fin is formed by correspondingly closing a first plate member and a second plate member to each other, such that a plurality of independent flow channels is defined between the closed first and second plate member. And, the independent flow channels respectively have an amount of working fluid filled therein.

In an embodiment, a cooling plate comprises a first substrate and a second substrate; wherein the first substrate and the second substrate are adhesively bonded via an adhesive layer; wherein a conduit is formed between the first substrate and the second substrate having an inlet and an outlet that forms a flow field for a coolant to flow through; wherein the adhesion layer forms a tight fluid seal to prevent leakage of the coolant from the conduit to a bonded region proximal to the conduit area between the first substrate and the second substrate.
