HIGH PERFORMANCE EVAPORATIVE BEAT EXCHANGE DEVICE BACKGROUND OF THE INVENTION
The present invention relates to a high performance evaporative heat exchange device for use in an air conditioner or refrigerator, and more particularly to such a high performance evaporative heat exchange device which comprises absorptive covering means covered on evaporator tubes to absorb cooling water and heat, enabling heat to be quickly carried away by evaporation.
The cooling of a regular condenser may be done by water or air. The air cooling method is to cool down the condenser by means of convection.However, this cooling method is less C C, C efficient, and suitable only for a small scale equipment. For a big scale air conditioning system, a big scale cooling fan shall be used with big condenser coils filled with Freon. This arrangement is expensive. Further, it consumes much energy and produces high noises during operatioh. The water cooling method is to cool down the condenser by cooling water. This method produces better effect, however it must be used with a cooling tower. When a cooling tower is built up, a piping system must be arranged between the cooling tower and the air conditioning system. It is complicated and dangerous to construct the cooling tower and the piping system.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a high performance evaporative heat exchange device for an air conditioning system which greatly improves the performance of the air conditioning system. It is another object of the present invention to provide a high performance evaporative heat exchange device for an air conditioning system which eliminates the ,CC'rO' installation of a cooling water tower and the related piping system.
C 00 COCI It is still another object of the present invention to provide a high performance evaporative heat exchange device which is inexpensive to manufacture. According to the present invention, the A high 00 0 00 performance evaporative heat exchange device comprises a casing, 0 C at least one evaporator tube respectively mounted in the casing, the at least one evaporator tube each comprising a heat conductive tube and an absorptive covering covered around the heat conductive tube, at least one water sprinkler respectively mounted in the casing to receive cooling water from a cooling water supply pipe and to sprinkle received cooling water on the at least one evaporator tube, and front and rear ventilation guard boards respectively covered on front and rear sides of the casing. Because cooling water is absorbed by the absorptive coverings of the at least one evaporator 2 tube, no water is wasted, and no water recycling system is needed. Because heat exchange is achieved by means of evaporation, the working pressure and temperature of the matter being cooled can be greatly lowered.

Referring to Figures I and 2, a high performance evaporative heat exchange device 1 can be designed of vertical type, L- shaped type, or U-shaped type.
Referring to Figure 3, the high performance evaporative heat exchange device 1 is comprised of a casing 2, a plurality of evaporator tubes 3, a plurality of water sprinklers 4, front and rear ventilation guard boards 5. Each evaporator tube 3 is comprised of a h eat conductive round tube 8 (see Figure 4A) or flat tube 9 (see Figure 413), and an absorptive covering 10 covered around the heat 4 conductive tube 8 or 9. The water sprinklers 4 receive cooling water from a water supply pipe (not shown), and sprinkle water on the evaporator tubes 3. The front and rear ventilation guard boards 5 keep sprinkled water from going in different directions out of the casing 2, so that supplied water can be fully utilized. When the heat exchange device is used in an air conditioner or industrial condenser, cooling water of the air conditioner or industrial condenser is guided to the water sprinklers 4, and then sprinkled by the water sprinklers 4 on the' absorptive coverings 10 of the evaporator tubes 3, enabling inside heat of the evaporator tubes 3 to be absorbed by the absorptive coverings 10 and then evaporated.
VOC Figure 5 shows a high performance evaporative heat exchange device according to a second embodiment of the present invention. According to this embodiment, the high performance evaporative heat exchange device is comprised of a casing 2, a plurality of evaporator boxes 6 mounted in the casing 2, front and rear ventilation guard boards 5 covered on front and rear sides of the casing 2.
Referring to Figures 6, 7 and 8, an evaporator box 6 is comprised of a shield 7, and a plurality of evaporator tubes 3 mounted in the shield 7 and arranged in parallel, each evaporator tube 3 being comprised of a heat conductive round tube 8 and an absorptive covering 10 covered around the heat conductive round tube 8.
Referring to Figures 9 and 10, when the high performance evaporative heat exchange device I is installed in an air conditioner or refrigerator, a fan 11 is turned by a fan motor 12 to cause currents of air, enabling water to be quickly evaporated from the heat exchange device 1 and then carried away from the heat exchange device 1.
Referring to Figure 11, two high performance evaporative C C, heat exchange device I may be arranged inside an air conditioner or refrigerator, and connected in parallel.
C 0 0 It is to be understood that the drawings are designed for purposes of illustration only, and are not intended as a definition of the limits and scope of the invention disclosed.
