Abstract
A heat exchanger used for an indoor unit in an air conditioner is S-shaped and is wound on two through-flow fan blades, the two ends of the heat exchanger are fixed on a base of the indoor unit, and the heat exchange volume and the heat exchange area of the heat exchanger are enlarged relative to those of conventional C-shaped heat exchanger, so that the heat exchange efficiency is higher. By adopting the heat exchanger, an air conditioner has the advantages that when the air volume is same, air passes through an evaporator twice, the heat exchange is sufficient, and the discharge air is ideal. Under the condition of meeting the heat exchange requirement, the rotating speed of the two through-flow fan blades can be lowered properly, so that the noise of the indoor unit of the air conditioner is lowered, and a user can feel comfortable.
Description
Technical field
The utility model relates to a kind of heat exchanger that is used for indoor apparatus of air conditioner, in particular for the heat exchanger of the indoor apparatus of air conditioner that adopts two through-flow fan blades.
Background technology
Heat exchanger generally is made up of heat exchange copper tube and heat radiation aluminium foil, is the important component part of air-conditioning.
The heat exchanger of indoor apparatus of air conditioner has " U " shape, " L " shape, " C " shape etc. at present.
Adopt the air-conditioning of two through-flow fan blades,, all adopt " C " shape heat exchanger 1 as shown in Figure 1 like cabinet air-conditioner." C " shape heat exchanger 1 covers on the through-flow fan blade, and its two ends are fixed on the indoor set base.During operation of air conditioner, air flows shown in arrow.When heat exchanger arrangement space one timing of indoor apparatus of air conditioner, the heat exchange area of above-mentioned " C " shape heat exchanger is restricted, and heat exchange efficiency is difficult to get a promotion.Along with the raising that national efficiency requires, the air-conditioning Energy Efficiency Ratio can only improve through improving the through-flow fan blade rotating speed in manufacturer, but causes the air-conditioning room noise to raise.
The utility model content
The utility model is the heat exchanger that is used for indoor apparatus of air conditioner is improved, thereby improves the air-conditioning heat exchange efficiency, reduces the air-conditioning noise.
For this reason, the utility model provides a kind of heat exchanger that is used for indoor apparatus of air conditioner, mainly is made up of heat exchange copper tube and heat radiation aluminium foil, and heat exchanger is the serpentine shape, is wrapped on two through-flow fan blades, and its two ends are fixed on the indoor set base.
The heat exchanger of the utility model, owing to adopt the serpentine shape, when it was wrapped in two through-flow fan blade, two present relatively " C " shape heat exchangers of heat exchange volume and area all obtained increasing, so heat exchange efficiency is higher.
In addition, the air-conditioning of the heat exchanger of employing the utility model is when refrigeration, and refrigerant is got into by serpentine shape lower end heat exchange copper tube, by the heat exchange copper tube output of serpentine shape upper end.Air is got into by serpentine shape the first half, after the heat exchanger heat exchange, the air that temperature reduces again with the heat exchange once more of serpentine shape the latter half.And the refrigerant temperature in serpentine shape the latter half of heat exchanger is lower.
In like manner, the air-conditioning of the heat exchanger of employing the utility model is when heating, and refrigerant is got into by serpentine shape upper end heat exchange copper tube, is exported by serpentine shape lower end heat exchange copper tube.Air is got into by serpentine shape the first half, after the heat exchanger heat exchange, the air that temperature raises again with the heat exchange once more of serpentine shape the latter half.And the refrigerant temperature in serpentine shape the latter half of heat exchanger is higher.
Therefore, adopt the air-conditioning of the heat exchanger of the utility model, under the situation of same air quantity, twice of air quantity be through evaporator, and heat exchange more fully, leaving air temp is better.On the other hand, under the situation that satisfies the heat exchange requirement, the motor speed that drives two through-flow fan blades can suitably reduce, and the noise of indoor apparatus of air conditioner is minimized, and it is more comfortable that the user can feel.
Description of drawings
Further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.
Fig. 1 is the structural representation of existing " C " shape heat exchanger;
Fig. 2 is the stereogram of the heat exchanger of the utility model;
Fig. 3 is the structural representation of the heat exchanger of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 2, shown in Figure 3, the heat exchanger that is used for indoor apparatus of air conditioner of the utility model mainly is made up of heat exchange copper tube and heat radiation aluminium foil, and heat exchanger 21 is the serpentine shape, is wrapped on two through-flow fan blades 231,232, and its two ends are fixed on indoor set base 22.The upper end heat exchange copper tube 211 of heat exchanger 21, lower end heat exchange copper tube 212 are respectively flowing to of refrigerant or flow out the position.
This heat exchanger, owing to adopt the serpentine shape, when it was wrapped in two through-flow fan blade, two present relatively " C " shape heat exchangers of heat exchange volume and area all obtained increasing, so heat exchange efficiency is higher.
The air-conditioning that adopts this heat exchanger is when refrigeration, and refrigerant is got into by serpentine shape lower end heat exchange copper tube 212, by heat exchange copper tube 211 outputs of serpentine shape upper end.Shown in the arrow as shown in Figure 3, air is got into by serpentine shape the first half, after heat exchanger 21 heat exchange, the air that temperature reduces again with the heat exchange once more of serpentine shape the latter half.And the refrigerant temperature in serpentine shape the latter half of heat exchanger is lower.
The air-conditioning of the heat exchanger of employing the utility model is when heating, and refrigerant is got into by serpentine shape upper end heat exchange copper tube 211, by 212 outputs of serpentine shape lower end heat exchange copper tube.Shown in the arrow as shown in Figure 3, air is got into by serpentine shape the first half, after the heat exchanger heat exchange, the air that temperature raises again with the heat exchange once more of serpentine shape the latter half.And the refrigerant temperature in serpentine shape the latter half of heat exchanger is higher.
Therefore, adopt the air-conditioning of the heat exchanger of the utility model, when same air quantity, twice of air be through evaporator, and heat exchange more fully, leaving air temp is better.On the other hand, under the situation that satisfies the heat exchange requirement, the motor speed that drives two through-flow fan blades can suitably reduce, and the noise of indoor apparatus of air conditioner is minimized, and it is more comfortable that the user can feel.
More than be one of embodiment of the utility model,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize the purpose of the utility model equally for those skilled in the art.But this variation obviously should be in the protection domain of claims of the utility model.
