Background technique
Central air-conditioning provides cold water using the form of centralized cooling supply for whole building, is then changed again by fan coil etc. Cooling capacity is sent to each room by hot component step by step.Although building structure has generally reserved certain space to central air conditioning Group, but the form of the evaporator of the water cooler of central air-conditioning is varied, including the knot such as shell-and-tube heat exchanger, plate heat exchanger Structure requires to occupy very large space.When especially refrigeration requirement is especially huge, multiple water coolers is needed to work at the same time When being just able to satisfy cooling capacity requirement, need to arrange enough evaporators in the same space as far as possible.
Dry evaporator refers in the coolant channel of evaporator, and refrigerant is in exit evaporating completely, no There are liquid refrigerant, such evaporator is exclusively used in air-cooled water cooler, is not suitable for cooling tower, therefore in condenser end segment Space is saved.But evaporator end also needs to save space, and more meticulous structure is needed to design.
Summary of the invention
It is an object of the invention to propose a kind of central air-conditioning flow-disturbing shell dry type heat exchanger.
To achieve this purpose, the present invention adopts the following technical scheme:
Central air-conditioning flow-disturbing shell dry type heat exchanger, including shell, copper pipe, drive end bearing bracket, rear end cap and spoiler;The shell is Cylindrical shell is provided with water inlet, water outlet, gas vent and drainage hole;The water inlet is by flanged joint in water inlet pipe, institute Water outlet is stated by flanged joint in outlet pipe, the gas vent is welded with casing, which installs exhaust valve again;The drainage hole It is welded with casing, which installs exhaust valve again;The copper pipe is entered in the shell by the lower half of the drive end bearing bracket, in institute It states and extends to the rear end of the shell in shell and turned back again to the upper half of the drive end bearing bracket;The inner wall of the copper pipe is smooth , outside wall surface is screw thread;For the excircle of the drive end bearing bracket by being bolted in the shell, the drive end bearing bracket is provided with medium Entrance and media outlet, the medium inlet are located at lower half, and the media outlet is located at the upper half;The medium inlet and Jie Matter outlet is welded with casing, which is provided with sinking step, the sinking step welding medium tube channel;It is given an account of The top of matter outlet is provided with venting plug;The excircle of the rear end cap is plugged in the rear end of the shell by bolt installation, Gasket is provided between the rear end cap and shell;The spoiler be more than semicircle discount vibram outlet, arrangement be part along It arranges to the interior of shell proportional spacing, the discount vibram outlet of adjacent spoiler is located at vertical two sides up and down, makes the shell Interior runner forms the channel for the turbulent flow that teeters.
Shell of the present invention occupies all spaces of entire evaporator, thus preset on the shell water and medium into Water outlet can save big quantity space, optimize the design of host;Inlet and outlet are easy for installation using flanged joint, hold Maintenance easy to maintain;The frequency of use of gas vent and drainage hole is not high, and failure rate is very low, lets out so can be reduced using welding method Dew.
