Disclosed in the present invention are a distributor for a plate heat exchanger, and a plate heat exchanger. The distributor includes; a tube part having a tube wall and having a first end and a second end; a first flange formed at the first end; and a connecting protrusion. The connecting protrusion projects from the tube wall of the tube part in a direction away from an axis of the tube part, and projects from the first flange at the inside of the outer edge of the first flange in a direction towards the second end of the tube part; the connecting protrusion has a connecting protrusion wall, which has an axial connecting protrusion wall that faces in the axial direction of the tube part and is remote from the first flange, the axial connecting protrusion wall being between the first end and the second end of the tube part, and having at least one through-hole. The distributor and plate heat exchanger according to embodiments of the present invention may reduce the manufacturing difficulty, and not only ensure excellent distribution, but may also avoid the risk of the through-hole being blocked by solder during brazing.

Various embodiments include heat exchangers and methods of making heat exchangers from a series of stacked plates each made of two foil sheets bonded together in bonding locations forming fluid flow passages between the foil sheets in regions where the foil sheets are not bonded. An inlet port and an outlet port located at opposite ends of the planar extent of the two foil sheets extend through the foil sheets perpendicular to the planar extent of the foil sheets. The inlet and outlet ports provide access for a first fluid to flow into or out of the internal plate passages formed between the two foil sheets. Interstitial channels are formed between the series of plates and configured to allow the flow of a second fluid between the series of plates, allowing heat to be transferred between the two fluids while isolating the two fluids from one another.

A brazed plate heat exchanger (100) for exchanging heat between at least two fluids comprises several elongate heat exchanger plates (110) provided with a pressed pattern comprising depressions and elevations adapted to keep the plates on a distance from one another by contact points between the elevations and depressions of neighboring plates under formation of interplate flow channels for media to exchange heat. At least four port openings are placed in corner regions of the elongate heat exchanger plates and have selective fluid communication with the interplate flow channels such that the fluids to exchange heat will flow between port openings parallel to long sides of the elongate heat exchanger plates. A circumferential seal sealing off the interplate flow channels from communication with the surroundings is provided, and the heat exchanger plates are joined by brazing. The circumferential seal results partly from contact between skirts of neighboring plates contacting one another, said skirts extending at least partly along two sides of each heat exchanger plates, and partly from contact between flat areas extending along two other sides of the heat exchanger plates.

A heat transfer plate and/or a plate heat exchanger including the heat transfer plate includes a plate body forming a patterned section and having a first side and a second side opposite to the first side; a gasket groove formed depressed from the plate body in a direction from the first side towards the second side, and having a bottom wall, the bottom wall having a bottom wall body; and where the gasket groove includes at least a first section with a first recess formed on the bottom wall body, depressed from the bottom wall body in the direction from the first side towards the second side, and a second section with a second recess formed on the bottom wall body, depressed from the bottom wall body in the direction from the second side towards the first side, wherein the second section is adapted to accommodate a gasket.

A liquid panel assembly configured to be used with an energy exchanger may include a support frame having one or more fluid circuits and at least one membrane secured to the support frame. Each of the fluid circuits may include an inlet channel connected to an outlet channel through one or more flow passages. A liquid is configured to flow through the fluid circuits and contact interior surfaces of the membrane(s). The fluid circuits are configured to at least partially offset liquid hydrostatic pressure with friction loss of the liquid flowing within the fluid circuits to minimize, eliminate, or otherwise reduce pressure within the liquid panel assembly.

Proposed is a thermoelement heat exchange module including a body and a thermoelement. The body has a cooling water flow path through which cooling water flows and has an opening which communicates with the cooling water flow path, and has an inlet which is formed at a first side thereof to communicate with the cooling water flow path and through which cooling water is introduced and has an outlet which is formed at a second side thereof to communicate with the cooling water flow path and through which cooling water is discharged. The thermoelement has a first surface thereof coupled to a portion where the opening of the body is formed such that the first surface is exposed on the cooling water flow path. The cooling water flow path has a portion having a relatively small hydraulic diameter in a flow direction of cooling water.
