The present invention provides wind guiding vane apparatus for mitigating a detrimental influence of cross winds flowing in the vicinity of an air-cooled condenser (ACC) and through one or more fans, positioned in lateral direction of the ACC, to which ambient air is directed and discharged to the atmosphere after cooling condenser tubes of the ACC, comprising one or more stationary wind guiding vanes positioned along at least a portion of an air flow streamline and below a plurality of condenser tubes of the ACC, wherein said one or more wind guiding vanes are configured to redirect air flow during windy conditions towards a portion of said plurality of condenser tubes and at least one of the fans at such an angle that significantly deviates from perpendicular, fairly horizontal inflow. The one or more wind guiding vanes are also suitable to maintain a nominal flow rate of air during quiescent wind conditions.

An adaptive condensing device for a dual-loop heat pipe air conditioner is presented. The adaptive condenser device may include a condenser body. A first electric shutter and a compressor condensing heat exchanger are disposed on one side of the condenser body, a second electric shutter and a heat pipe condensing heat exchange micro-channel are disposed on the other side of the condenser body, and a fan is disposed on the top of the condenser body. This may give rise to the compressor and the heat pipe being able to perform refrigeration under the working condition, and there may be no need to configure two condensers, thereby reducing installation space, facilitating installation and maintenance, and reducing costs.

The present invention is directed to a load bearing direct-drive system for driving a fan in a cooling system such as a wet-cooling tower, air-cooled heat exchanger, HVAC system, hybrid cooling tower, mechanical tower or chiller system. The present invention includes a variable process control system that is based on the integration of key features and characteristics such as tower thermal performance, fan speed and airflow, motor torque, fan pitch, fan speed, fan aerodynamic properties, and pump flow. The variable process control system processes feedback signals from multiple locations in order to control a high torque, low variable speed, load bearing motor to drive the fan.

An air-cooled condenser system for steam condensing applications in a power plant Rankine cycle includes an air cooled condenser having a plurality of interconnected modular cooling cells. Each cell comprises a frame-supported fan, inlet steam headers, outlet condensate headers, and tube bundle assemblies having extending between the headers. The tube bundle assemblies may be arranged in a V-shaped tube structure. A plurality of deflection limiter beams are arranged coplanar with the tube bundles. Top ends of each deflection limiter beam are slideably inserted in an associated floating end cap affixed to an upper tubesheet which moves vertically relative to the beams via thermal expansion/contraction concomitantly with the tubes. The deflection limiter beams provides guided restraint system for expansion/contraction of the tube bundles which prevents out of plane tube bowing.

A PCCS condenser may include a first and a second stage condenser. Each of the first and second stage condensers may include channels in fluid communication between an inlet and an outlet header. The inlet header of the first stage condenser may be configured to receive a fluid mixture through a first inlet opening. The channels may be configured to condense water from the fluid mixture flowing through the channels from the inlet header to the outlet header, respectively, of the first and second stage condenser. The PCCS condenser may include a catalyst in at least one of the outlet header of the first stage condenser or the inlet header of the second stage condenser. The catalyst may catalyze a reaction for forming water from hydrogen and oxygen in the fluid mixture. The outlet header of the second stage condenser may be in fluid communication with a combined vent-and-drain line.

A condenser includes heat transfer pipe groups, a main body and an intermediate body. The intermediate body has an inlet that opens in a horizontal direction, and an outlet that opens downward. The main body has an inlet that opens upward and is connected to the intermediate body outlet. The heat transfer pipe groups are arranged in the horizontal direction and disposed in the main body. A near-side outlet edge is an edge of the intermediate body outlet on a side near the intermediate body inlet in the horizontal direction and a far-side outlet edge is an edge of the intermediate body outlet on a side far from the intermediate body inlet. At least one part of the main body is located below an imaginary line that connects the near-side and far-side outlet edges and at least one part of the main body is located above the imaginary line.
