Description

Finned heat exchanger and air-conditioner

Technical field

The utility model relates to air-conditioning technical field, particularly a kind of finned heat exchanger and air-conditioner with this finned heat exchanger.

Background technology

At present, in the situation that the prices of raw and semifnished materials constantly rise, how economizing on resources, reduce cost has become each air-conditioning manufacturer urgent problem.

As shown in Figure 1, existing finned heat exchanger for air conditioner comprises fin 1 and heat exchanger 2, and wherein, the spacing between two fins 1 all equates, namely only has a kind of spacing of fin L in the same finned heat exchanger.Owing to present heat exchanger fin constant gap, can there be the situation of the wasting of resources.Illustrate: when the setting spacing of fin was 1.3mm, the number of fins that the long heat exchanger of 1M needs was about 770.In this case, the exchange capability of heat of heat exchanger has exceeded the real work requirement, and some fin is unnecessary.If reduce number of fins and simply strengthen spacing of fin, for example when becoming 1.4mm to spacing of fin, number of fins is down to is about 715, then the exchange capability of heat of heat exchanger descends, and does not reach again requirement.Therefore can only adopt front a kind of scheme, spacing of fin is set as 1.3mm, have in the face of the situation of resource (such as product material, mold materials etc.) waste.

Summary of the invention

Main purpose of the present utility model is to provide a kind of finned heat exchanger, is intended to effectively solve the technical problem that there is the wasting of resources in present finned heat exchanger for air conditioner.

In order to realize the utility model purpose, the utility model provides a kind of finned heat exchanger, comprises the fins set that sets in a row, and described fins set comprises the fin that some non-equidistances arrange.

Preferably, the spacing of described fin is two kinds, and relatively large its quantity of fin of spacing accounts for 2/3rds of fin sum, the spacing less account for 1/3rd.

Preferably, the spacing of described fin is two kinds, and relatively large its quantity of fin of spacing accounts for the fin sum and accounts for 1/2nd, the spacing less account for 1/2nd.

Preferably, the relatively large fin of spacing and the fin of spacing less are interspersed in the described fins set.

Preferably, the spacing of described fin is three kinds, and the fin of three kinds of different spacing respectively accounts for 1/3rd of fin sum.

The utility model also provides a kind of air-conditioner, and it comprises finned heat exchanger.This finned heat exchanger comprises the fins set that sets in a row, and described fins set comprises the fin that some non-equidistances arrange.

The utility model reduces the fin of some by the fin in the fins set is the non-equidistance setting, has saved resource, has improved the situation of the existing wasting of resources of prior art, and the manufacturing of heat exchanger and material cost are minimized.

The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

The utility model provides a kind of finned heat exchanger, and with reference to Fig. 2 and Fig. 3, in the utility model embodiment, this finned heat exchanger comprises heat exchanger tube 10 and the fins set 20 that sets in a row, and wherein, fins set 20 comprises the fin that some non-equidistances arrange.Among the utility model embodiment, finned heat exchanger can comprise a row or multi-row fins set, in each fins set 20 between two fins for be arrangeding in parallel, have two or more spacing, for example the spacing between some fins is 1.3mm, and the spacing between other fins is 1.4mm.Should be noted that; among the utility model embodiment; spacing between the fin is not limited to 1.3mm or 1.4mm; can also be 1.2mm, 1.5mm or 2.0mm etc.; the utility model embodiment only limited protection domain of the present utility model in order to describe the technical scheme of the utility model embodiment in detail, to should not be construed as for numerical value.

The utility model reduces the fin of some by the fin in the fins set 20 is the non-equidistance setting, has saved resource, has improved the situation of the existing wasting of resources in the prior art, and the manufacturing of heat exchanger and material cost are minimized.

Among the utility model embodiment, the fin of different fin spacing shared ratio in fins set 20 can be set as required.The arrangement mode of the fin of different fin spacing in fins set 20 can be set according to demand.Below will illustrate:

In a preferred embodiment, the spacing of fin is two kinds in the fins set 20, and relatively large its quantity of fin of spacing accounts for 1/2nd of fin sum, the spacing less account for 1/2nd.Concrete, as shown in Figure 2, in the present embodiment, there are two kinds of spacings between the fin in the fins set 20, be respectively L1 and L2, L2 is relatively large, and the L1 less.Spacing be its quantity of fin of L1 account for fin 20 sums in the heat exchanger 1/2nd, spacing is that its quantity of fin of L2 accounts for remaining 1/2nd.The concrete numerical value of L1, L2 can be set according to the actual requirements.For example L1 is set to 1.3mm, and L2 is set to 1.4mm etc.

In another preferred embodiment of the present utility model, the spacing of fin is two kinds in the fins set 20, and relatively large its quantity of fin of spacing accounts for 2/3rds of fin sum, the spacing less account for 1/3rd.As shown in Figure 3, in the present embodiment, there is the fin of 2 kinds of different spacing.Spacing is that its quantity of fin of L1 accounts for 1/3rd of fins set 20 sums, and spacing is that the fin of L2 accounts for 2/3rds.The concrete numerical value of L1, L2 can be set according to the actual requirements.For example, 1/3rd fin 20 can be set and adopt 1.3mm spacing, i.e. L1=1.3mm; 2/3rds fin adopts the 1.4mm spacing, and namely L2=1.4mm compares the heat exchanger that uses 1.3 mm spacings of fin fully, and the heat exchanger of per 1 meter length can reduce by 27 fins, has therefore reached economical with materials cost, waste, the purpose that economizes on resources.

With reference to shown in Figure 4, in the preferred embodiment of the present utility model, the fin of the fin that above-mentioned spacing is relatively large and spacing less can be interspersed, and namely spacing is that L1 and spacing are that the fin of L2 is interspersed.Spacing is that fin shared ratio in the fin sum of L1 and L2 can be set according to demand.

In another preferred embodiment of the present utility model, the spacing of fin is three kinds in the fins set 20, and the fin of three kinds of different spacing respectively accounts for 1/3rd of fin sum.As shown in Figure 5, in the present embodiment, there is the fin of 3 kinds of different spacing in fins set 20.Spacing is that its sum of fin of L1 accounts for 1/3rd of fin sum, and spacing is that the fin of L2 also accounts for 1/3rd, and spacing is that the fin of L3 accounts for remaining 1/3rd.The concrete numerical value of L1, L2, L3 also can be set according to the actual requirements.

The utility model also provides a kind of air-conditioner, and it has finned heat exchanger.Among the utility model air-conditioner embodiment, the structure of finned heat exchanger and operation principle can be with reference to the embodiment of earlier figures 1 ~ Fig. 5 and corresponding finned heat exchanger thereof, and it has comprised all features of aforementioned finned heat exchanger, does not therefore just give unnecessary details.The utility model air-conditioner has been saved resource owing to adopt aforementioned finned heat exchanger, and its material and manufacturing cost are minimized.

It below only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
