In various embodiments, the present invention relates to heat dissipation systems including a hygroscopic working fluid integrating waste water as makeup water. The present invention also relates to methods of using the same. The present invention also relates to hygroscopic cooling systems adapted to dispose of waste water by combining the waste water with a hygroscopic working fluid, precipitating impurities and evaporating the remaining water.

Trickle bodies for the air conditioning of, in particular, animal housings, that possess only partially latticed layer elements. Trickle bodies are formed of a plurality of sandwiched layer elements that, in known trickle bodies, are formed of corrugated and completely latticed plastics foil. The trickle bodies formed of such layer elements possess a relatively low stability and a limited evaporation capacity. The plastics-formed layer elements of the instant invention are produced by injection molding, allowing layer elements having corrugation heights of more than 12 mm to be formed. Such trickle bodies are more stable, enable a high evaporation capacity and are, moreover, also less permeable to light.

The invention relates to a heat exchanger device with at least one heat exchanger (1) which is flowed through by a fluid, at least one fan (11) and at least one adiabatic air cooler (2) for cooling air which is drawn in from the surroundings by the fan (11), wherein the air that has been drawn in is conducted firstly through the air cooler (2) and subsequently through the heat exchanger (1) and the adiabatic air cooler (2) has at least one humidification means (3), which is arranged in the air cooler (2) and which is composed of a moisture-absorbing material and a liquid feed (4), which feeds a liquid to the humidification means (3) in order to keep the humidification means (3) moist. In order that the most uniform possible wetting of the humidification means and higher heat exchange performance can be made possible without an impairment of the stability and the handleability of the humidification means and without oversaturation of the humidification means in the upper region with the liquid, provision is made whereby the humidification means (3) comprises at least two mats (3a, 3b) arranged one above the other and whereby the liquid feed (4) has a distributor device (4a, 4b) which is arranged above each mat (3a, 3b) and which serves for uniformly distributing the liquid onto the mats (3a, 3b), wherein each distributor device (4a, 4b) is connected to a feed line (5) via which the distributor devices (4a, 4b) can be charged with the liquid.

A friction welding machine for radiating fins is disclosed, which mainly uses a moving unit to drive a friction joint unit to approach the plurality of radiating fins, and a friction rod provided in the moving unit rotates at a high speed to penetrate the radiating fins. The radiating fins are then welded together through the heat generated by high-speed rotation friction to achieve the purpose of improving the welding quality of the radiating fins and reducing the cost.

A hybrid wet/dry cooling tower and novel splash fill material are provided. In one embodiment, the cooling tower includes a wet cooling section having a draft fan disposed above the wet section for drawing air through the wet section to cool liquid traversing the wet section. The cooling tower also includes a dry cooling section disposed laterally adjacent the wet section and configured to enable the draft fan to draw air through the dry section. In another embodiment, the dry cooling section has one or more added draft fan(s) for drawing air through the dry section with or without operation of the draft fan disposed above the wet section. In other embodiments, different structures and configurations of plastic splash fill material are described.
