Abstract
The present invention provides a heat exchanger for air condition. A heat exchanger is constituted of a plurality of fins and tubes passing through these fins and arranged there. A mounting interval of the tubes of the heat exchanger near a lateral flow fan is formed short and a mounting space of the tubes of the heat exchanger is formed gradually wide as they are spaced apart from the lateral flow fan. With such an arrangement as above, since an air flow rate at the location of each of the tubes of the heat exchanger is relatively uniformly distributed irrespective of a spaced-apart distance from the lateral flow fan, a heat transfer efficiency of the heat exchanger is improved and generation of noise is reduced.
Description
The present invention is relevant with the heat exchanger of air-conditioner, and is more particularly, in order to obtain uniform airflow VELOCITY DISTRIBUTION in heat exchanger, in order to improve hot transfer efficiency and in order to reduce to move noise, relevant with the architecture advances of this heat exchanger.
The professional and technical personnel is known, once propose and use air-conditioner to heat a room or cool off a room with refrigerant with hot water.With reference to Fig. 1, the structure of the typical heat exchanger of one air-conditioner is shown on perspective view, at this accompanying drawing 1, the main body of label 10 expressions one air-conditioner, the tubular heat exchanger of band fin is placed on the inside of main body 10, and a cylindricality horizontal flow fan 15 flatly is placed on the back of heat exchanger 20 bottoms.Above-mentioned flange-cooled shell and tube heat exchanger 20 has several vertical rectangle fin of placing 21 and several flow of refrigerant pipes 23, and these flow duct 23 levels are passed all fin 21 and interconnected mutually at the pipe end of giving prominence to outermost fin 21.In the heat exchanger 20 of above-mentioned band fin-tube type, carry out heat exchange at pipe 23 flowing refrigerant (not shown) and air, air flows between fin 21, shown in Fig. 1 arrow.
Fig. 2 is the side view of a typical heat exchanger 20, expression one is around the air stream of heat exchanger 20, as shown in the figure, when the cylindricality horizontal flow fan rotates, in air or the room air suck air conditioner main body 10 inside and and the refrigerant in the pipe 23 carry out heat exchange and simultaneously air between fin 21, flow, shown in Fig. 2 arrow, after carrying out heat exchange with refrigerant, air enters in the space from main body 10.In typical heat exchanger 20, the pipe 23 that flatly passes fin 21 separates by well-balanced interval, and the well-balanced interval between pipe 23 is exactly so-called " step pitch ".In typical heat exchanger 20, as shown in Figures 2 and 3, pipe 23 is spaced apart with well-balanced step pitch, be higher than around air velocity degree around air velocity degree like this away from the heat exchanger top B of cylindricality horizontal flow fan 15 near the heat exchanger 20 bottom A of cylindricality horizontal flow fan 15, as shown in Figure 3, therefore, around the air velocity degree of bottom A greater than air velocity around top B, because it is its heat exchanger effectiveness step-down and generation operating noise that the uneven distribution of the pipe 23 caused air velocitys at well-balanced interval, typical heat exchanger 20 produce a defective.
So, the purpose of this invention is to provide a heat exchanger that is used for air-conditioner, this can be by reducing to such an extent that overcome above-mentioned defective than the shorter even distribution that reaches air velocity of step pitch between away from cylindricality horizontal flow fan place pipe near the step pitch between the cylindricality horizontal flow fan place pipe.So just can improve heat transfer efficiency and reduce operating noise.
In order to achieve the above object, the invention provides a heat exchanger that is used for air-conditioner, this air-conditioner comprises and is provided with some fin, some flow of refrigerant pipes and the mobile fan of cylindrical cross-section that is placed on the heat exchanger back, improvement wherein has: the flow of refrigerant pipe is settled in the following manner promptly and is being tapered to shorter than the step pitch that flows between the fan place pipe away from cylindrical cross-section in the step pitch that flows near cylindrical cross-section between the fan place pipe.
Step pitch between the flow of refrigerant pipe can be according to cylindrical cross-section the flow position of fan and change.
With reference to accompanying drawing, from the narration to embodiment hereinafter, other purpose of the present invention just becomes more obvious, wherein:
Fig. 1 represents the perspective view of the typical heat converter structure of an air-conditioner;
Fig. 2 is the side view of a typical heat exchanger, and the air stream around heat exchanger is shown;
Fig. 3 is the side view of a typical heat exchanger, and the VELOCITY DISTRIBUTION around the air stream of heat exchanger is shown;
Fig. 4 is according to most preferred embodiment of the present invention, and the lateral perspective of fin in the heat exchanger of an air-conditioner illustrates different step pitch between the heat exchanger flow of refrigerant pipe;
Fig. 5 is the side view of a heat exchanger, and the distribution around heat exchanger air velocity degree is shown.
Fig. 4 is according to most preferred embodiment of the present invention, and the lateral perspective of fin in the heat exchanger of an air-conditioner illustrates the asynchronous distance between the flow of refrigerant pipe in the heat exchanger.Fig. 5 is the side view of a heat exchanger, and the distribution around the air velocity degree of heat exchanger is shown.
In the accompanying drawings, some rectangle fin of the flange-cooled tube type heat exchanger 30 of label 31 expressions, wherein fin 31 is placed in the air conditioner casing 50, and some flow of refrigerant pipes 33 flatly pass all fin 31 of heat exchanger 30 and are connected with each other at the pipe end of giving prominence to outermost fin 31.Heat exchanger 30 of the present invention is characterized in that the step pitch between the flow of refrigerant pipe 31 reduces in the following manner gradually, is the shortest and be the longest around the step pitch away from the top of cylindricality horizontal flow fan 35 around the step pitch near the bottom of cylindricality horizontal flow fan 35 promptly.Just, in most preferred embodiment of the present invention, the step pitch d between the pipe 33 around heat exchanger 30 bottoms
1Be shorter than the step pitch d between the pipe 33 on every side of heat exchanger 30 tops
2, because cylindricality horizontal flow fan 35 typically is placed on the bottom in the air conditioner casing 50.Step pitch d when certainly, also being appreciated that top in cylindricality horizontal flow fan 35 is placed on air conditioner casing 50
1And d
2Between relation then conversely.
Around the VELOCITY DISTRIBUTION of the air of heat exchanger 30 of the present invention stream as shown in Figure 5, in Fig. 5, the size of the relevant air velocity degree of the length of each arrow representative.Because the step pitch d between the pipe 33 as mentioned above around heat exchanger 30 bottoms
1Be shorter than the step pitch d between the pipe 33 on every side of heat exchanger 30 tops
2So air successfully flows in the bottom of the top of heat exchanger 30 and heat exchanger 30, air velocity is uniformly in whole heat exchanger like this, and knot wants heat exchanger of the present invention just to reach the even distribution of air velocity degree shown in Fig. 5 arrow.
In sum, by the step pitch between the flow of refrigerant pipe is reduced gradually, be the shortest and step pitch that flow between the fan place pipe away from cylindrical cross-section is the longest near flow step pitch between the fan place pipe of cylindrical cross-section like this, the heat exchanger of one air-conditioner of the present invention has just reached the even distribution of air velocity degree, thereby this heat exchanger has improved its heat transfer efficiency and reduced operating noise.
Though for illustrative purposes, most preferred embodiment of the present invention is open, can carry out various modifications concerning this professional those of ordinary skill, replenishes and replaces, only otherwise depart from disclosed in the claims protection scope of the present invention and spirit.
