(b) Description of the Prior Art
Thermoelectric air conditioners generally available in the market are provided with a hollow cabinet containing a chamber, and a water inlet and a water outlet connecting through the chamber. Some manufacturers have added a fin in the chamber to stabilize water flow and thus to enlarge contact area between water and the water tank and to extend contact time. However, the water maintains higher flowing speed, i.e., the contact time between water flow and cabinet of the water tank becomes comparatively short. Consequently, the water upon entering from the water inlet fails to execute sufficient heat exchange with the cabinet of the water tank before directly flowing out of the water outlet in a shorter route. Therefore poor heat transfer compromises the general heat transfer efficiency of the water tank to lower the heat transfer efficiency of the air conditioner.

(2) A water trough is milled at each opposite ends of any two abutted partitioning boards in the structural form;
(3) Both of the upper and the lower surfaces of the fin are coated with a solder and place laterally in each waterway of the structural form, the structural form is then heated up to a temperature allowing soldering, a given pressure is applied on the surface of the structural form to narrow down a distance between two surfaces of the structural form thus to execute close contact with both of the upper and the lower surfaces of the fin, and the structural form is left cooling down for the fin to be soldered to where between both surfaces of the structural form;
(4) Two sealing plates are respectively soldered to both openings on two sides of the casing while a water inlet and a water outlet are disposed at both ends of either sealing plate to complete the manufacturing of a cabinet for the heat transfer water tank; and

Therefore, the water flow achieves sufficient contact with walls of the fin and the partitioning board to increase contact area between water and the heat transfer water tank, thus to extend contact time allowing sufficient heat exchange with the cabinet of the heat transfer water tank for upgrading heat transfer efficiency of the heat transfer water tank as a whole.
Referring to
The cabinet 1 contains a casing 2 and two sealing plates 7 respectively sealing up both ends of the casing 2; the casing 2 is provided with a chamber with both sides respectively disposed with an opening. Multiple partitioning boards 6 are disposed in the chamber of the casing 2; and they arranged in parallel with one another and secured at where between two opposite flat surfaces of the casing 2 to divide the chamber of the casing 2 into multiple waterways 8 independent from one another. Those partitioning boards and the casing 2 are related to an integrated part extruded from an aluminum ingot. On two opposite ends of each abutted two partitioning boards 6 are respectively disposed with a water trough 9. Those water troughs 9 allow those waterways 8 in the cabinet 1 to connect through one another in sequence by head and tail of each waterway 8. A fin 3 to stabilize water flow is disposed in each waterway 8 and the fin 3 is provided lengthwise along the waterway 8 in a size corresponding to that of the space of the waterway 8. In the preferred embodiment, the fin 3 is related to a serrated fin (similar to that disclosed in Chinese Patent Application No. 200520077600.4 titled “Heat Exchanger with Plate Fins), a straight fin or a porous fin (not illustrated). A water inlet 4 and a water outlet 5 are disposed on one side of the cabinet 1 (to facilitate converging of water route of the air conditioner). The heat transfer water tank in the structure described above allows water to flow from the water inlet 4 into the water tank; pass through each and all waterways 8 in an S-shaped route and flow out of the water outlet 5. Meanwhile, the water flow has sufficient contact with the fin 3 and the partitioning board 6 to enlarge contact area between the water and the water tank thus to extend contact time permitting sufficient heat exchange between water and the cabinet of the water tank in upgrading heat transfer efficiency of the water tank as a whole.
To manufacture the heat transfer water tank of the present invention, an aluminum ingot is extruded into an integrated structural form comprised of a casing containing a chamber with both sides respectively provided with an opening and multiple partitioning boards. Wherein, a cross section of each partitioning board 6 indicates a “>” shape; and those partitioning boards 6 are arranged in parallel with one another at where between two surfaces of a casing 2 to divide the chamber of the casing 2 into multiple waterways independent from one another. On opposite ends of any two abutted partitioning boards 6 are respectively a water trough 9 by milling, i.e., a water trough is milled on one tail of a partitioning board while another water trough is milled on a head of another partitioning board abutted. Both of an upper surface and a lower surface of the fin 3 are coated with solder and laterally placed in the waterway 8 of the structural form, which is then heated up to a melting temperature allowing a soldering process in a range of 580° C.˜620° C. when the structural form starts to get soft; a given pressure is applied to a surface of the structural form for a distance between two surfaces of the structural form to be narrowed down to 0.1 mm˜0.3 mm so to engage close contact with both of the upper and the lower surfaces of the fin 3; the structural form is left cooled to secured the fin 3 by soldering at where between two surfaces of the structural form. Two sealing plates 7 are respectively soldered to both side openings of the casing 2, the water inlet 4 and the water outlet are disposed on both ends of either sealing plate 7 to complete the manufacturing of the cabinet 1. Finally, the cabinet 1 is formed on its outer surface an insulation heat transfer layer by using the micro-arc oxidization (MAO) method. Alternatively, the MAO method may be applied before soldering the sealing plates.
The section of the partitioning board 6 as indicating the “>” shape in the preferred embodiment as described above may be made an arc; or those erected partitioning boards 6 are each inclined for a given angle; arranged in parallel with one another, and fixed at where between two surfaces of the casing 2 to reduce resistance from the partitioning board 6 against both opposite surfaces of the cabinet 1 when getting closer to each other under pressure.
