Abstract: The present disclosure provides a plate heat exchanger comprising: a plurality of heat transfer plates stacked in a first direction, wherein the heat transfer plate is configured to have a heat transfer plate edge on its side in a second direction perpendicular to the first direction; first and second fluid channels formed between adjacent heat transfer plates and fluidly isolated from each other; two first ports formed in the heat transfer plate on the side and an opposite other side of the heat transfer plate in the second direction, respectively, and fluidly communicated to the first fluid channel; and a hole formed in the heat transfer plate between one of the two first ports located on the side and the heat transfer plate edge in a second direction, which is fluidly communicated to the first fluid channel and fluidly isolated from the second fluid channel. By disposing the hole in a bottom area of the plate heat exchanger, excessive water remained in the plate heat exchanger when it is not in use is avoided, so as to prevent freezing in the plate heat exchanger.

Abstract: A plate heat exchanger comprises a heat exchanger plate having a quadrilateral shape with two opposite primary sides and two opposite secondary sides, and a longitudinal central axis being parallel with the primary sides. The heat exchanger plate comprises a heat exchanger area having a corrugation of ridges and valleys. Four porthole areas are located at a respective corner of the heat exchanger plate and each comprises a respective porthole extending through the heat exchanger plate. An edge area extends around and adjoins the heat exchanger area and the porthole areas. The heat exchanger area comprises a main area and a local part area extending along one of the primary sides and adjoining the edge area and one of the porthole areas. The valleys of the local part area are tapering towards the longitudinal central axis.

Abstract: The present invention introduces a heat exchanger including a stack of heat transfer plates positioned between two end plates in which recesses formed in edge regions are adapted to accommodate bolts reaching from a first to a second of said two end plates, said at least one of said recesses formed with locking features adapted to engage with a locking device including an opening, where the locking device is to be positioned on the respective end plate with the opening aligned with the recess in such a manner that a bolt positioned in the recess also can project through said opening. This prevents the bold from falling out of the recesses.

Abstract: A heat exchanger is disclosed. The heat exchanger includes a stack of plates extending between an upper end plate and a lower end plate. The lower end plate includes four lateral walls extending in the direction of the stack. The stack of plates forms an alternation of first canals for the first fluid and of second canals for the second fluid. The heat exchanger includes a first inlet and at least two first outlets which are fluidically connected to the first canals. The upper end plate includes the first inlet. At least one of the lateral walls includes the at least two first outlets.

Abstract: Display assemblies with thermal management features are provided. The display assemblies include an image assembly, a housing for the image assembly having an intake and exhaust. A first, continuous airflow pathway is located within the housing, and includes a first portion located forward of the image assembly and a second portion located rearward of the image assembly. A second airflow pathway extends within the housing between the intake and the exhaust. A heat exchanger located within the housing and rearward of the image assembly includes a first set of ducted passageways forming part of the first airflow pathway and a second set of ducted passageways forming part of the second airflow pathway. The first set of ducted passageways extend alongside, in an alternating fashion with, the second set of ducted passageways.

Abstract: An electronic display assembly includes an electronic display located within a housing. A first airflow pathway fluidly connected to an ambient environment extends through at least a portion of the housing. A second airflow pathway, separated from the first airflow pathway, forms a closed loop within the housing. Some or all electronic components for operating the electronic display assembly are located within the second airflow pathway, such as to at least partially isolate such electronics from dust or other containments in ambient air.

Abstract: The invention relates to a heat exchanger that is configured to permit an exchange of heat between a first fluid and a second fluid that circulate in passage paths formed by plates (14a, 14b) and fins (16a, 16b) of the heat exchanger, the fluids flowing in a multitude of passage channels (10) each consisting of a closed space (12) delimited by two adjacent plates and two adjacent fins, characterized in that each plate extends along a non-planar surface following at least a first oscillating curve, and each fin further following at least one second oscillating curve along at least one second main direction, in such a way that each passage path allows the fluid to flow in the closed space along a fluid direction defined by a generatrix that is a combination at least of the first oscillating curve and the second oscillating curve.
