Description

Water cooler dual system dry type heat exchanger

Technical field

The present invention relates to technical field of central air more particularly to water cooler dual system dry type heat exchangers.

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 water cooler dual system dry type heat exchanger.

To achieve this purpose, the present invention adopts the following technical scheme:

Water cooler dual system dry type heat exchanger, including shell, copper pipe, drive end bearing bracket, rear end cap and spoiler；The shell is circle Column shell is provided with water inlet, water outlet, gas vent and drainage hole；The water inlet is described by being threadedly connected to water inlet pipe Water outlet is threaded with casing by being threadedly connected to outlet pipe, the gas vent, which installs exhaust valve again；The draining Hole is threaded with casing, which installs exhaust valve again；The copper pipe enters the shell by the lower half of the drive end bearing bracket It is interior, it is turned back again in the rear end for extending to the shell in the shell to the upper half of the drive end bearing bracket；The inner wall of the copper pipe Face and outside wall surface are screwed surface；The excircle of the drive end bearing bracket is connected to the front end of the shell, the front end Lid is provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at the upper half；It is described The middle of the inside of drive end bearing bracket is provided with the lagging and perpendicular baffle of right-angled intersection, thus by the inner space of the drive end bearing bracket It is divided into upper left quarter, lower left quarter, upper right quarter and right lower quadrant；The copper pipe is divided into two systems, a system as medium channel It is that medium from lower left quarter enters copper pipe, goes out copper pipe from upper left quarter, another system is that medium from right lower quadrant enters copper pipe, from the right side Top is gone out copper pipe；The rear end cap is welded in the rear end of the shell, and the rear end cap is welded by cylindrical shell and spherical calotte It connects, the cylindrical shell is connect with the rear end of the shell；The spoiler is the discount vibram outlet more than semicircle, and arrangement is portion Divide and arranged along the interior of shell proportional spacing, the discount vibram outlet of adjacent spoiler is located at vertical two sides up and down, makes institute State the channel that the runner in shell forms 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；Water inlet, water outlet, gas vent and drainage hole are all made of spiral shell Line connection, it is easy for installation, and it is easy Maintenance and Repair；Failure rate is lower for flanged joint.

Specific embodiment

To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.

Water cooler dual system dry type heat exchanger, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；Institute Stating shell 1 is cylindrical shell, is provided with water inlet 11, water outlet 12, gas vent 13 and drainage hole 14；The water inlet 11 by It is threadedly connected to water inlet pipe, the water outlet 12 is threaded with casing by being threadedly connected to outlet pipe, the gas vent 13, should Casing installs exhaust valve again；The drainage hole 14 is threaded with casing, which installs exhaust valve again；Shell 1 occupies whole All spaces of a evaporator, therefore preset water and the intake-outlet of medium on shell 1 and can save big quantity space, it is excellent The design of host is changed；Water inlet 11, water outlet 12, gas vent and drainage hole 14 are all made of threaded connection, easy for installation, and And it is easy Maintenance and Repair；Failure rate is lower for flanged joint.The copper pipe 2 by the drive end bearing bracket 3 lower half into Enter in the shell 1, is turned back again in the rear end for extending to the shell 1 in the shell 1 to the upper half of the drive end bearing bracket 3； The inner wall and outside wall surface of the copper pipe 2 are screwed surface；The inside and outside wall surface of copper pipe 2 is all that thread surface can increase Strong heat exchange area reduces energy consumption to improve heat exchange efficiency；Before the excircle of the drive end bearing bracket 3 is connected to the shell 1 End, the drive end bearing bracket 3 are provided with medium inlet 31 and media outlet 32, and the medium inlet 31 is located at lower half, the medium Outlet 32 is located at the upper half；The middle of the inside of the drive end bearing bracket 3 is provided with the lagging and perpendicular baffle of right-angled intersection, thus The inner space of the drive end bearing bracket 3 is divided into upper left quarter, lower left quarter, upper right quarter and right lower quadrant；The copper pipe 2 is logical as medium Road is divided into two systems, and a system is that medium from lower left quarter enters copper pipe 2, goes out copper pipe 2 from upper left quarter, another system is Medium enters copper pipe 2 from right lower quadrant, goes out copper pipe 2 from upper right quarter；When needing to increase the refrigeration work consumption of host, simple system Power has certain limiting value, cannot infinitely increase, therefore left and right two systems are arranged in same evaporator shell 1, thus Make that there is bigger refrigerating capacity in the volume of the same evaporator.

The rear end cap 4 is welded in the rear end of the shell 1, and the rear end cap 4 is welded by cylindrical shell and spherical calotte It forms, the cylindrical shell is connect with the rear end of the shell 1；

Welding back shroud 4 reduces manufacturing cost, while also ensuring the airtightness of container；

The spoiler 5 is the discount vibram outlet more than semicircle, and arrangement is that part is arranged along the 1 inside proportional spacing of shell Column, the discount vibram outlet of adjacent spoiler 5 are located at vertical two sides up and down, so that the runner formation in the shell 1 is teetered disorderly The channel of stream.

Snakelike flow-disturbing improves heat exchange efficiency, can increase the turbulence factor of water flow under upper and lower installation condition, and raising is changed The thermal efficiency；

It is bolted at least screw-in depth 60mm.

The thickness of copper pipe is not less than 0.6mm；The screw thread of the copper pipe of every 1cm is no less than 22 circles.

The width of the lagging and perpendicular baffle is not less than 8mm.
