According to one embodiment, a heat exchanger includes a pipe through which a fluid flows, and a supply device that supplies the fluid to the pipe. The pipe includes a flexible part deformed by flowing of the fluid, and a constricted part located at a downstream side of the flexible part along a flow direction of the fluid.

A heat exchanger includes an outer packaging member. The outer packaging member is configured to allow a heat transfer medium flowed to an inside of the outer packaging member from a heat transfer medium inlet to pass through the inside and flow out from a heat transfer medium outlet. The outer packaging member is made of outer packaging laminate materials each including a metal heat transfer layer and a resin thermal fusion layer provided on one surface of the heat transfer layer. The outer packaging laminate materials are superimposed one on the other. The thermal fusion layers are integrally bonded along peripheral edge portions of the outer packaging laminate materials. The heat transfer layer and the thermal fusion layer of the outer packaging laminate material are laminated via an inner adhesive agent layer made of an acid-modified polyolefin-based adhesive agent containing an acid-modified polyolefin-based resin.

A heat pipe structure includes a first plate, a second plate and a plurality of wick structures. The second plate is connected to the first plate to form a chamber. The wick structures are disposed in the chamber, and the distribution shape of the wick structures is approximately the same as the shape of a portion of the chamber. The chamber is formed by at least one coupling portion and three or more extending portions. The coupling portion communicates with the extending portions, and the contour of the connected first and second plates is different from that of the chamber.

A method for closing a fillable collecting tank, in particular a fillable collecting tank of a heat exchanger for storing a fluid, having walls forming the collecting tank, wherein one of the walls is formed as a baseplate having openings for receiving pipes, wherein a filling opening for adding the fluid is provided in one of the walls, wherein the filling opening can be closed by the provision of a closure element that can be inserted into the filling opening or can be placed onto the filling opening after the fluid has been added to the collecting tank. A heat exchanger is also provided.

Apparatuses and methods associated with heat exchanger puck design are disclosed herein. In embodiments, a heat exchanger puck may include a first plate with a cavity that extends into the first plate from a side of the first plate and a second plate. The second plate may be coupled to the side of the first plate, with the cavity located between the first plate and the second plate. The heat exchanger puck may further include a tube of a liquid coolant system located, at least partially, within the cavity, the tube formed to fit the cavity created by the first plate and the second plate. Other embodiments may be described and/or claimed.

Provided is a heat exchange element that suppresses an increase in air-flow resistance by suppressing deflection of a partition member caused by a change in temperature and humidity. The unit constituent members are stacked, each of which is formed of partition members that have heat-transfer properties and moisture permeability, and spacing members that hold the partition members. A primary air flow that passes along an upper-surface side of the partition member and a secondary air flow that passes along an undersurface side of the partition member cross each other so as to exchange heat and moisture via the partition member. The spacing member includes: spacing ribs that maintain the spacing between the partition members; and deflection suppressing ribs that have a height smaller than the spacing ribs so as to suppress deflection of the partition members.

A cooling plate design for cooling a battery cell is provided that employs a plastic plate having cutouts for coolant flow paths. The plastic plate has a layer of adhesive film on each side to maintain coolant in the channels. Compression within an alternating battery cell and coolant plate stack provides pressure that minimizes coolant load on the film. Methods to manufacture the cooling plate are also provided.

A heater device includes a flexible heat generating portion, a surface layer that covers a front side of the heat generating portion, and a heat insulating portion that covers a back side of the heat generating portion and blocks heat generated by the heat generating portion. The heat generating portion, the surface layer, and the heat insulating portion are configured as a laminate in which the surface layer, the heat generating portion, and the heat insulating portion are laminated in this order via an adhesive. The laminate has a plurality of slits for suppressing deformation due to differences in the linear expansion coefficients of the heat generating portion, the surface layer and the heat insulating portion.

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 fluid heating system assembly including: a first tube sheet; a second tube sheet opposite the first sheet; a heat exchanger tube, which connects the first tube sheet and the second tube sheet; a baffle such as a plate baffle and/or an annular baffle disposed between the first tube sheet and the second tube sheet, wherein the heat exchanger tube passes through the baffle.
