Air conditioner heat transfer water tank and manufacturing process thereof

Abstract

A heat transfer water tank adapted to an air conditioner and a manufacturing process thereof includes a cabinet containing a chamber; the cabinet includes a casing containing the chamber and provided on both sides each an opening; a sealing plate is fixed to seal up each opening; a sealing plate is disposed with a water inlet and a water outlet connecting through the chamber of the casing; the chamber is divided into multiple waterways by partitioning boards; on two opposite ends of any two abutted boards being each disposed with a water trough to permit waterways to be connected through one another; and a fin being provided in each waterway; the water upon entering from the water inlet passes each waterway before finally flowing out of the water outlet to enter into a next cycle; the water flow is given sufficient contact with the fin and the board to increase contact area and extend contact time for sufficient heat exchange to upgrade heat transfer efficiency.

1 . A heat transfer water tank adapted to an air conditioner comprising a cabinet containing a chamber; the cabinet including a casing; the casing containing the chamber; both sides of the casing being respectively provided with an opening; a sealing plate is fixed to seal up each opening; both ends of a sealing plate are disposed with a water inlet and a water outlet respectively connecting through the chamber of the casing; the chamber is divided into multiple waterways independent from one other by means of multiple partitioning boards; on two opposite ends of any two abutted partitioning boards being each disposed with a water trough to permit those waterways to be connected through one another by a head and a tail of each waterway; and a fin being provided in each waterway to stabilize water flow and disposed lengthwise along the waterway. 
   
   
       2 . The heat transfer water tank adapted to the air conditioner as claimed in  claim 1 , wherein each of those partitioning boards has its section indicating an arc; all partitioning boards are arranged in parallel with one another and secured at where between two opposite surfaces of the casing. 
   
   
       3 . The heat transfer water tank adapted to the air conditioner as claimed in  claim 1 , wherein each of those partitioning boards has its section indicating a “>” shape; all partitioning boards are arranged in parallel with one another and secured at where between two opposite surfaces of the casing 
   
   
       4 . The heat transfer water tank adapted to the air conditioner as claimed in  claim 1 , wherein each of those partitioning boards is inclined at a given angle; arranged in parallel with one another and secured at where between two opposite surfaces of the cabinet. 
   
   
       5 . The heat transfer water tank adapted to the air conditioner as claimed in  claim 1 , wherein an insulation heat transfer layer is formed on an outer surface of the cabinet. 
   
   
       6 . The heat transfer water tank adapted to the air conditioner as claimed in  claims 1  through  5 , wherein the fin is soldered and secured at where between two opposite surfaces of the cabinet. 
   
   
       7 . A process for manufacturing the heat transfer water tank adapted to the air conditioner comprising the following steps:
 (1) An aluminum ingot is molded by extrusion into an integrated structural form of a casing containing a chamber, having both sides respectively provided with an opening, and multiple partitioning boards to divide the chamber of the casing into multiple waterways independent from one another;   (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   (5) An insulation heat transfer layer is formed using a micro-arc oxidization (MAO) method on the outer surface of the cabinet of the heat transfer water tank.   
   
   
       8 . The process for manufacturing the heat transfer water tank adapted to the air conditioner as claimed in  claim 7 , wherein each of those partitioning boards has its section indicating a “>” shape; all partitioning boards are arranged in parallel with one another and secured at where between two opposite surfaces of the casing in Step (1). 
   
   
       9 . The process for manufacturing the heat transfer water tank adapted to the air conditioner as claimed in  claim 7 , wherein the soldering temperature falls within a range of 580° C.˜620° C. in Step (3). 
   
   
       10 . The process for manufacturing the heat transfer water tank adapted to the air conditioner as claimed in  claim 7 , wherein a distance between two surfaces of the structural form is narrowed down to a range within 0.1 mm˜0.3 mm in Step (3).
