The heat exchanger consists of a number of stainless steel tubes (greater than two) each having the same diameter and gently twisted together to form a single heat exchanger. The spigots located at each end of the outer tube thus form manifolds for the tubes of the heat exchanger. A heat exchanger fluid is introduced in the space between the outer tube and the heat exchanger to provide the necessary exchange of heat in the device. Because the heat exchanger is connected by manifolds of the same end spigot, each tube of the heat exchanger carries the same product.

A condenser with capillarity cooling devices provides a condenser that has a plurality of cooling fins with a wick structure and a plurality of capillary water absorption layers of which the lower section is submerged in the water of a water reservoir provided underneath. Through capillarity and the characteristic of the capillary water absorption layers, water will be brought upward to moisturize the fins. When the water evaporates, a great amount of heat will be extracted from the fins, so as to increase the thermal efficiency of the condenser. Further, a pre-wetting water pipe is included, so that when an air conditioner is switched on and the condenser is started, the pre-wetting water pipe moisturizes the capillary water absorption layers immediately, and such moisture extends to the overall wick structures of fins. This will make evaporation take place instantly and thermal efficiency of condenser is increased.

A heat sink with a built-in fan includes a heat radiation base, a heat radiation fin module and a fan. The heat radiation base has a plurality of spaced grooves formed on an inner side thereof for engagement of heat radiation fins of the heat radiation fin module. The heat radiation fins are respectively inserted in the grooves of the heat radiation base and compressed in the grooves by stamping so that the heat radiation fins are connected to the heat radiation base. The fan is located inside the heat radiation fin module and surrounded by the plurality of heat radiation fins. When the heat radiation base absorbs heat, the fan is started to dissipate heat quickly. At least one heat conduction pipe is connected between the heat radiation base and the heat radiation fin module to enhance the heat dissipation efficiency of the heat sink.

The basic principle is applicable to cooling, heating or a combination of both. The definition of the TMZ is Key to this patent application! It is a volumetric space described as (L×W×D), length×width×depth, through which the air passes to be cooled or heated. Traditional AC units move air through the TMZ horizontally a distance of “D,” the depth of the core unit. Using the same configuration for the core unit with the same TMZ volume, the difference is airflow direction and temperature transfer duration. The proposed Patent Design moves air through the TMZ longitudinally a distance of “L,” the length of the core unit, allowing more time to heat or cool the air. If the air is colder or warmer as it leaves the TMZ it will stay cold or warm longer as it modifies the room air temperature, conserving energy!
