A heat exchanger and an antenna assembly having the same are described herein that enable a compact antenna design with good thermal management. In one example, a heat exchanger is provided that includes tube-shaped body. A main cooling volume is formed between the top and bottom surfaces proximate to the outside wall. The main cooling volume has an inlet formed through the top surface and an outlet formed through the bottom surface. A return volume is formed adjacent the inside diameter wall and is circumscribed by the main cooling volume. The return volume has an outlet formed through the top surface and an inlet formed through the bottom surface. One or more exterior fins are coupled to an exterior side of the outside wall. A plurality of fins extend into the main cooling volume. A plurality of inner fins extend into a passage from the inside diameter wall.

The present disclosure discloses a heat exchanger including a group of collecting pipes and a number of heat exchange assemblies. Each heat exchange assembly includes a fin plate and at least one heat exchange tube. The heat exchange assembly includes a main heat exchange area. The heat exchange tube is connected with the fin plate. The heat exchange tube at least partially protrudes from at least one side of the fin plate. In addition, in the main heat exchange area corresponding to two adjacent heat exchange assemblies, at least two adjacent heat exchange tubes are staggered along an array direction of the heat exchange assemblies. The two heat exchange tubes respectively belong to the two adjacent heat exchange assemblies. The present disclosure is beneficial to improve the performance of the heat exchanger.

A heat exchanger includes a heat exchanger core. The heat exchanger core includes a plurality of tubes. Each tube of the plurality of tubes includes a first end and a second end and extends from the first end to the second end in a lengthwise direction. Each tube of the plurality of tubes is spaced from adjacent tubes in a height-wise direction and a widthwise direction. The plurality of tubes is stacked to create a concave profile in the height-wise direction and widthwise direction. The concave profile extends in the lengthwise direction.

A honey processing apparatus that is configured to provide processing of a wax/honey emulsion so as to separate the honey from the wax and provide separate collection thereof. The present invention includes a vessel having a first chamber and a second chamber. The first chamber includes an interior volume having a heating fluid disposed therein. The second chamber is also disposed within the interior volume of the first chamber and wherein the heating fluid is surroundably present thereto. A coil is present within the second chamber and the coil is fluidly coupled with the heating fluid. A pump is operably coupled to the coil and is configured to provide closed-loop recirculation of the heating fluid within the coil so as to provide heating of the wax/honey emulsion in order to facilitate the separation thereof. A honey extraction tube coupled with the second chamber provides extraction of the honey.

A plate heat exchanger includes a plurality of heat transfer plates stacked together and each having openings at four corners thereof. The heat transfer plates are partially brazed together such that a first flow passage through which first fluid flows and a second flow passage through which second fluid flows are alternately arranged with one of the heat transfer plates disposed therebetween, openings at the four corners being connected forming first headers through which the first fluid enters and is discharged and second headers through which the second fluid enters and is discharged. At least one of two heat transfer plates between which the first flow passage or the second flow passage is disposed is formed by a pair of metal plates stacked together. The metal plate adjacent to the second flow passage is thinner than the metal plate adjacent to the first flow passage.

A heat exchanger includes a first manifold having an inlet opening and a second manifold having an outlet opening. A group of conduits fluidly connect the first manifold and the second manifold to one another such that a flow path is established for liquid to flow from the inlet opening to the outlet opening. The flow path includes a select portion that extends through all conduits within the group of conduits. Valves are located in the first manifold and the second manifold. The valves are operable to change the select portion of the flow path from between a first state, wherein the conduits within group of conduits are fluidly connected in parallel with one another, and a second state, wherein the conduits within the group of conduits are fluidly connected in series with one another.
