Description
Technical field
The present invention relates to heat exchanger, particularly be arranged in the heat exchanger in the indoor set of air conditioner, and the indoor set of air conditioner.
Background technology
A plurality of heat exchanging part are combined formed heat exchanger in mutual angled mode, are to use in the past always.This heat exchanger can form various shape that adheres to specification by the combination of heat exchanging part.And a plurality of heat exchanging part of formation heat exchanger have various length (opening the 2001-4162 communique referring to the spy) mostly respectively.For example, in the heat exchanger that indoor set had of air conditioner, have to form the heat exchanger that inverted v-shaped surrounds Air Blast fan.This heat exchanger is combined the heat exchanging part of all lengths, forms the shape of inverted v-shaped, and heat exchanging part and the heat exchanging part that covers top, Air Blast fan rear that it covers Air Blast fan the place ahead have different length.
Saidly more than assembling combine and during the heat exchanger that forms, exist the error problem of each heat exchanging part setting angle by a plurality of heat exchanging part that have angle.That is, have under the situation of error, can make the position of heat exchanger end produce error, thereby can produce and make the inappropriate danger of layout or the like of heat exchanger at the setting angle of heat exchanging part.Therefore, wish that the error of heat exchanging part setting angle is as much as possible little, yet, if will try to achieve too sternly to tolerance, will reduce the assembling performance of heat exchanger.
On the other hand, even the setting angle error of heat exchanging part is identical, the site error of heat exchanger end also can increase because of the length lengthening of heat exchanging part.Therefore, can consider to reduce the admissible error of setting angle by shortening the length of heat exchanging part.
, if shorten the length of heat exchanging part, exchange capability of heat that then can the heat exchanging device exerts an influence.That is, if reduce the length of heat exchanging part, the total surface area that the surface area of each heat exchanging part is added heat exchanger has together just reduced, the result, and the exchange capability of heat of heat exchanger has descended.So, in order to reduce the admissible error of heat exchanging part setting angle, only use this way of length that shortens heat exchanging part, can cause exchange capability of heat to descend.
Summary of the invention
The indoor set that the purpose of this invention is to provide a kind of like this heat exchanger and air conditioner, it can also reduce the admissible error of heat exchanging part setting angle when preventing that exchange capability of heat from descending.
The heat exchanger of being put down in writing in the claim 1 is formed by connecting by a plurality of heat exchanging part, and it is arranged in the indoor set of air conditioner, has first heat exchanging part, second heat exchanging part and the 3rd heat exchanging part.Second heat exchanging part is connected an end of first heat exchanging part in angled mode.The 3rd heat exchanging part is connected the other end of first heat exchanging part in angled mode.And second heat exchanging part and the 3rd heat exchanging part have roughly the same length.
In this heat exchanger, second heat exchanging part has identical length with the 3rd heat exchanging part.Under the identical situation of the total length of heat exchanger, when the length of second heat exchanging part and the 3rd heat exchanging part is identical, because the maximum of the heat exchanger end position error that error caused of its setting angle is asynchronous littler than the length of two heat exchanging part.That is, under second heat exchanging part situation different with the 3rd heat exchanging part length, a side length is long, and the opposing party's length is short.At this moment, the site error of the heat exchanger end that heat exchanging part caused that length is long is just big.On the other hand, if the total length of heat exchanger is identical, when the length of second heat exchanging part and the 3rd heat exchanging part was identical, the length of long heat exchanging part was short for length when the length of its heat exchanging part will be more different than length.Therefore, this heat exchanger can reduce the admissible error of heat exchanging part setting angle when preventing that exchange capability of heat from reducing.
The heat exchanger of being put down in writing in the claim 2, in the heat exchanger that is in claim 1 to be put down in writing, its first heat exchanging part has the section configuration that roughly is inverted v-shaped.And second heat exchanging part and the 3rd heat exchanging part are extended from the lower ends downward side of first heat exchanging part front and back respectively.
When the lower end of second heat exchanging part and the 3rd heat exchanging part became the lower end of heat exchanger respectively, the error of the setting angle of second heat exchanging part and the 3rd heat exchanging part will influence the site error of heat exchanger lower end.
, in this heat exchanger, because the same length of second heat exchanging part and the 3rd heat exchanging part, so just reduced by the maximum of the site error of the heat exchanger lower end that error caused of setting angle.Like this, in this heat exchanger, just can reduce the admissible error of the setting angle of second heat exchanging part and the 3rd heat exchanging part.
The heat exchanger of being put down in writing in the claim 3, in the heat exchanger that is in claim 1 to be put down in writing, symmetrical before and after the shape of symmetry before and after having, second heat exchanging part and the 3rd heat exchanging part.
In this heat exchanger, because symmetry before and after second heat exchanging part and the 3rd heat exchanging part, so the same length of second heat exchanging part and the 3rd heat exchanging part.Like this, just can reduce the admissible error of the setting angle of second heat exchanging part and the 3rd heat exchanging part.

[characteristics]
[1] in the indoor heat exchanger 50 that the indoor set 2 of this air conditioner 1 is had, heat exchanger 50d has same length in the 3rd indoor heat exchanger 50c and the fourth ventricle.When seeing from the side, under the identical situation of the total length of indoor heat exchanger 50, the situations different with the length of heat exchanger 50d in the fourth ventricle with the 3rd indoor heat exchanger 50c are compared, and the maximum of the end position error of the indoor heat exchanger 50 that causes owing to the error of setting angle has reduced.
For example, shown in Figure 10 (b), consider an imaginary indoor heat exchanger 500.In addition, Figure 10 (a) represents the indoor heat exchanger 50 that the indoor set 2 of an air conditioner 1 is had.Imaginary indoor heat exchanger 500 is the same with indoor heat exchanger 50, is made of the 11 indoor heat exchanger 500a, the 12 indoor heat exchanger 500b, the 13 indoor heat exchanger 500c and four parts of the 14 indoor heat exchanger 500d.The formation of each indoor heat exchanger 500a, 500b, 500c, 500d is roughly identical with indoor heat exchanger 50, but, constitute the 13 indoor heat exchanger 500c of imaginary indoor heat exchanger 500 front ends, different with the length of the 14 indoor heat exchanger 500d that constitutes imaginary indoor heat exchanger 500 rear ends, the length of the 13 indoor heat exchanger 500c is longer.But, the total length that the 13 indoor heat exchanger 500c and the 14 indoor heat exchanger 500d add up to, the total length that adds up to heat exchanger 50d in the 3rd indoor heat exchanger 50c and the fourth ventricle is identical.Therefore, when seeing from the side, indoor heat exchanger 50 has same length with imaginary indoor heat exchanger 500, and has roughly the same surface area.
Investigate in this indoor heat exchanger 50 and the imaginary indoor heat exchanger 500, the alignment error of each indoor heat exchanger is to the influence of the site error of indoor heat exchanger lower end, and its result is as follows.Figure 11 (a) is the ideograph of lower end, indoor heat exchanger 50 front side, and Figure 11 (b) is the ideograph of lower end, imaginary indoor heat exchanger 500 front side.In addition,, in these two figure, simplified each indoor heat exchanger 50b, 50c, 500b, 500c, represented these indoor heat exchangers with straight line for the ease of understanding.
When the 3rd indoor heat exchanger 50c being connected the second indoor heat exchanger 50b lower end with right-on angle, the 3rd indoor heat exchanger 50c should be as represented with imaginary line among the figure, be parallel to vertical direction, but, setting angle error alpha to a certain degree in fact will be produced.Therefore, the 3rd indoor heat exchanger 50c has formed angle [alpha] with respect to vertical direction.In the imaginary indoor heat exchanger 500 shown in Figure 11 (b), the 13 indoor heat exchanger 500c also is connected with the lower end of the 12 indoor heat exchanger 500b with same setting angle error alpha.Therefore, the 13 indoor heat exchanger 500c has also formed angle [alpha] with respect to vertical direction.Like this, under the situation that indoor heat exchanger 50c, 500c connect with the setting angle error alpha, it is far away more to leave link position, and the each several part of indoor heat exchanger 50c, 500c leaves uses the distance of the represented ideal position of imaginary line just big more among the figure.Therefore, even the setting angle error alpha is identical, length is the site error Δ D2 of the 13 long indoor heat exchanger 500c lower end, and also the site error Δ D1 than the 3rd indoor heat exchanger 50c lower end is big.That is, the site error Δ D2 of lower end, imaginary indoor heat exchanger 500 front side is bigger than the site error Δ D1 of lower end, indoor heat exchanger 50 front side.
As mentioned above, the part that constitutes the indoor heat exchanger lower end is long more, and then the site error of indoor heat exchanger lower end is just big more.Otherwise the part that constitutes the indoor heat exchanger lower end is short more, and then the site error of indoor heat exchanger lower end is just more little.Therefore, if the length that the indoor heat exchanger lower end adds up to is identical, the situations different with each several part length are compared, and just can reduce the maximum of lower end position error.Therefore, in indoor heat exchanger 50 of the present invention, the 3rd indoor heat exchanger 50c is identical with the length of the interior heat exchanger 50d of fourth ventricle.Like this, in indoor heat exchanger 50, the setting angle error of heat exchanger 50d is just smaller for the influence of the site error of indoor heat exchanger 50 lower ends in the setting angle error of the 3rd indoor heat exchanger 50c and the fourth ventricle.So, in indoor heat exchanger 50, just can relax the admissible error of the setting angle of heat exchanger 50d in the admissible error of setting angle of the 3rd indoor heat exchanger 50c and the fourth ventricle.In addition, because the admissible error of having relaxed setting angle, the assembling performance of indoor heat exchanger 50 has just improved.
