Description

Prevent flying water evaporimeter heat-dissipating band structure

Technical Field

The invention belongs to the technical field of air conditioner evaporators, and particularly relates to a heat dissipation belt structure of a water splashing prevention evaporator.

Background

The existing air conditioner evaporator has certain problems, such as the problem of generating water flying under specific environment and special working conditions.

When the air conditioner starts to refrigerate, the refrigerant in the evaporator begins to change phase, the refrigerant absorbs a large amount of heat when changing from liquid state to gas state, so that the ambient environment is rapidly cooled, when normal temperature air passes through the surface of the evaporator with lower temperature, the normal temperature air is changed into low temperature air, and the air flows to the cab through the air duct of the air conditioner, so that the refrigerating effect is achieved. However, the air contains a large amount of water vapor, and when the air meets an evaporator with lower temperature, condensation is generated on the surface, and a large amount of water is formed and attached to the surface of the evaporator. When a certain amount of water is accumulated, most of condensed water gradually drops downwards through the upper windowing position of the heat dissipation belt due to the fact that air at a certain flow velocity blows over the evaporator under the action of gravity, and is continuously drained downwards, so that a large amount of water can be discharged by a household air conditioner or an automobile air conditioner when the air conditioner is started for refrigeration.

Under a specific working condition, if the air volume is suddenly increased at the initial stage of turning on the air conditioner, the phenomenon of water splashing can occur. When the refrigeration is started, the evaporator does not immediately discharge water, the water storage mode is started, as shown in fig. 7, the water discharge is started after the water accumulation reaches the peak value of the water storage weight, and the air conditioner suddenly increases the air volume at each time, and the water which has not reached the discharge is blown out of the surface to form flying water. In addition, because the structural design of the evaporator is not appropriate, if the window is short in length, water drops are blocked and cannot be drained in time, the water storage capacity is large, the water splashing state is caused all the time, and meanwhile, the heat exchange performance is greatly reduced.

Disclosure of Invention

The invention aims to solve the defects of the background technology and provide a radiating belt structure of a water-splashing prevention evaporator. The evaporator heat dissipation belt is used for increasing the grooves, the proper window opening angle and the length, so that the surface water storage capacity of the evaporator can be better reduced, and the problem of evaporator water splashing is solved.

The technical scheme adopted by the invention is as follows: the utility model provides a prevent flying water evaporimeter heat-dissipating band structure, includes to converge pipe, converges pipe, cooling tube down, breathing pipe, feed liquor pipe, the cooling tube with converge the pipe on, converge the pipe down and be connected, feed liquor pipe, breathing pipe are connected with converging the pipe on or converge the pipe down respectively and form airtight cavity, still include the heat dissipation area, the heat dissipation area is connected with the cooling tube, it has a plurality of grooves to open on the heat dissipation area.

In a further preferred structure, the wave height H of the heat dissipation band is 6.03mm ± 0.08mm, the window length L1 is 5.2mm ± 0.2mm, and the window angle is 30 ° ± 4 °.

In a further preferred configuration, the grooves are arranged offset in the front-rear direction of the heat dissipation belt.

In a further preferred structure, the length L2 and the width w of the groove of the heat dissipation tape are 2mm ± 1mm and 2mm ± 1mm, respectively.

In a further preferred construction, the radiating band and the radiating pipe have the same fitting width.

Further preferably, the evaporator is mounted in the air-conditioning case at an inclination angle α larger than 5 °.

According to the invention, the grooves are formed in the radiating belt, the radiating pipe and the radiating belt are assembled at the same height, and the assembling position of the evaporator in the air conditioner shell is specified, so that the problem of water flying of the evaporator is solved by reducing the surface water storage capacity of the evaporator and accelerating drainage on the premise of ensuring the refrigerating performance. Multiple tests show that the invention can reduce the peak water storage capacity by at least 50g and reduce the water storage capacity by 15%. The evaporator has good drainage and can prevent the problem of water flying during refrigeration of an air conditioner.

The invention has the following advantages:

1. on the premise of determining the wave height, under the condition of meeting the required strength of a heat dissipation belt, when the windowing length is increased to the maximum value, the windowing angle is too small, water drops are blocked, when the windowing angle is too large, the wind resistance is increased, the performance is reduced, and the optimal windowing angle is 30 degrees +/-4 degrees through multiple times of data simulation.

2. The length and the width of the groove of the heat dissipation belt are respectively 2mm +/-1 mm, the front and the back of the groove position are staggered, the strength of the heat dissipation belt is increased due to the first reason, the local strength of the heat dissipation belt at one position is prevented from being reduced, the drainage capacity is accelerated due to the second reason, condensate water on the heat dissipation belt drops downwards along the groove position, and the wave crest and the wave trough of the heat dissipation belt correspond to groove holes.

3. The heat dissipation band and the heat dissipation pipe are assembled at the same height. Because of having the fluting on the cooling tube, the comdenstion water stays through fluting department, does not need the cooling tube assembly to exceed the cooling tube and takes the formation edge, makes things convenient for comdenstion water cooling tube edge to stay. The same additional advantage of heat dissipation area and cooling tube assembly height because of heat transfer area improves, and the performance also can improve simultaneously.

4. The evaporator is mounted in the air conditioning case at an inclination angle alpha greater than 5 deg.. When air blows across the evaporator surface to generate flying water, the trajectory of the parabola formed by the water droplets is changed. The flying area is reduced to a certain extent.
