Problems solved by technology

Due to the large number of weld beads and dense distribution on the serpentine runner condensing plate, the welding heat input of the ordinary resistance welding method is relatively large, and because the linear expansion coefficient of stainless steel is large and the thermal conductivity is low (about 17w / m×kJ), resistance welding It is easy to generate large welding residual stress, which will lead to deformation and warping of the serpentine flow channel condensation plate after welding and subsequent use. The flow channel is easy to form dead angles, and the refrigerant and condensing oil are easy to accumulate.

Abstract

The invention discloses a stainless steel snakelike flow channel cold plate and a processing molding method thereof. The snakelike flow channel cold plate adopts a stainless steel plate and consists of a stainless steel upper plate, a stainless steel lower plate, an inlet pipe and an outlet pipe, wherein the two stainless steel plates are overlapped and connected by a water-cooling resistance welding method; the inlet pipe and the outlet pipe are inserted in the upper end and the lower end between the two stainless steel plates and are connected with the stainless steel snakelike flow channel cold plate by using an electric arc welding method; and then the snakelike flow channel cold plate is finally molded through a mould and high-pressure bulging technology.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a stainless steel serpentine flow channel condensation plate and a processing and forming method thereof. Background technique [0002] The stainless steel serpentine flow channel condensation plate is generally made of two 1-3mm thick 304 stainless steel plates with a length of 1.2-1.8m and a width of 0.5-1.2m through ordinary resistance welding to form a serpentine flow channel. The serpentine flow channel condensing plate is bulged to form a serpentine flow channel condensing plate, allowing the refrigerant (such as R-22 or ammonia) to flow in the hollow flow channel. Due to the large number of weld beads and dense distribution on the serpentine runner condensing plate, the welding heat input of the ordinary resistance welding method is relatively large, and because the stainless steel linear expansion coefficient is large and the thermal conductivity is low (about 17w / m×kJ),...
