Abstract
An heat exchange coiled pipe for an evaporative cooler comprises an inlet pipe, snake-shaped heat exchange pipes and an outlet pipe, wherein the inlet pipe and the outlet pipe are connected with the snake-shaped heat exchange pipes respectively through collecting pipes; the two ends of the collecting pipes are sealed by collecting pipe seals; the snake-shaped heat exchange pipes are arranged in a zigzag shape; the included angle formed by the two adjacent layers of heat exchange pipes is 1 to 3 DEG; nickel phosphorus coating with the thickness of 30 to 70 microns is formed on the inner walls of the snake-shaped heat exchange pipes; and the snake-shaped heat exchange pipes are fixed and supported by a frame. The nickel phosphorus coating is formed on the inner walls of the snake-shaped heat exchange pipes, so corrosion and erosion of corrosive gas and heat-transfer mediums on the heat exchange pipes can be avoided effectively and the service life of the heat exchange bundle is prolonged greatly; the nickel phosphorus coating has the thickness of 30 to 70 microns, so the thickness of the coating is reduced as much as possible on the premise of achieving the protective effect, and the problems of high cost, long production time and reduced heat exchange efficiency caused by over thickness of the coating are avoided.
Description
Technical field
The utility model relates to the heat exchange field of heat transfer, specifically the heat exchange coil used of a kind of evaporative type cooler.
Background technology
In the system of petrochemical refining, contain acrid H in a lot of media
2The S composition, serious to equipment harm, particularly when heat exchange is conducted heat, if contain H in the heat transfer medium
2S, the exchange heat pipe can cause serious burn into souring under the situation of high temperature and media flow, greatly reduces the service life of heat exchanger tube.
The utility model content
For solving in the prior art heat exchanger tube at high-temperature corrosion environment low problem in following service life, the heat exchange coil that the utility model provides a kind of evaporative type cooler to use.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: the heat exchange coil that a kind of evaporative type cooler is used, comprise inlet tube, snakelike heat exchange tube and outlet, wherein, described inlet tube is connected with snakelike heat exchange tube by collector respectively with outlet, the two ends of collector are by the sealing of collector end socket, described snakelike heat exchange tube is in a zigzag arranges, the angle that the adjacent two layers heat exchanger tube becomes is 1-3 °, the inwall of snakelike heat exchange tube is provided with the nickel phosphor plating rete that thickness is the 30-70 micron, and snakelike heat exchange tube supports by frame fixation.
In the utility model, for preventing that the heat exchanger tube outside from being corroded, be provided with nickel phosphor plating rete or galvanizing layer at the outer wall of described snakelike heat exchange tube.
In the utility model, the flatness when guaranteeing that heat transferring medium flows in heat exchanger tube connects by return bend between the adjacent two-layer heat exchanger tube in snakelike heat exchange tube.
In the utility model, described collector is provided with two rows' snakelike heat exchange tube, cross arrangement between the snakelike heat exchange tube.
Beneficial effect: the utility model arranges the nickel phosphor plating rete by the inwall at heat exchanger tube, the corrosion that can effectively prevent etchant gas and heat transfer medium exchange heat pipe is washed away, improved the service life of heat-exchanging tube bundle greatly, the thickness of nickel phosphor plating rete is the 30-70 micron, possessing the thickness that has reduced coating under the prerequisite of protective effect as much as possible, preventing the blocked up cost height that causes of thickness of coating, the long problem that has reduced heat exchange efficiency of production time; The angle that while adjacent two layers heat exchanger tube becomes is 1-3 °, can increase the flowing velocity of heat transfer medium in heat exchanger tube, has reduced the time of heat transferring medium in pipe.
