Abstract
The utility model discloses an evaporator which comprises a shell (1) for transmitting a heat-transfer fluid medium, a heat-transfer fluid medium input tube (2) and a heat-transfer fluid medium output tube (3) which are arranged on the shell (1), and a plurality of pipelines (4) used for transmitting a refrigerant and arranged in the shell (1), wherein a diversion device is arranged on a joint of the output tube (2) and the shell (1). The evaporator also comprises a diversion ring (51) arranged on the input tube (2), wherein one end of the diversion ring (51) is connected with the inner wall of the input tube (2), and the other end of the diversion ring (51) outwards smoothly extends into the shell (1) to form a circular arc diversion ring. The evaporator has the advantages that when a heat-transfer fluid medium is transmitted from the input tube (2) to the evaporator, the heat-transfer fluid medium is guided by the diversion ring (51) to be dispersed all around so that the medium is divided into multiple portions from one portion, thus direct washing of the heat-transfer fluid medium to the pipelines (4) is effectively lightened, and the service life of the pipelines (4) is prolonged.
Description
Technical field
The utility model relates to the air-conditioning equipment field, specifically is a kind of evaporimeter.
Background technology
Evaporimeter is an important component part in the air-conditioning equipment, is to utilize heat transfer medium with the heat transferred cold-producing medium, the heat exchanger that makes cold-producing medium absorb heat and flash to gas and take away heat.Now people use always is that shell and tube evaporator comprises the housing that is used to transmit heat-transfer fluid medium (water, saline solution, ethylene glycol solution etc.), is arranged on heat-transfer fluid medium input pipe and efferent duct on the housing, and is contained in the some pipelines that are used to transmit cold-producing medium in the housing.The heat-transfer fluid medium inputs in the housing from input pipe, carries out heat transmission through contacting with duct wall, and heat is passed to the cold-producing medium in the pipeline.
But in actual use, the heat-transfer fluid medium is when input pipe gets into; Generally the flow velocity with 1.2 ~ 2.5m/s directly washes away pipeline; And the pipeline that uses in the evaporimeter of prior art adopts the heat exchange effect to encircle finned tube preferably, and the wall thickness of ring finned tube is thinner than common pipe; Constantly washing away down of heat-transfer fluid medium, pipeline shortening in service life.Especially evaporator application is when underground water operating mode source pump, and underground water is carrying the grains of sand and getting in the evaporimeter, direct again impulse piping, and pipeline is very easy to damaged, thereby causes the unit cisco unity malfunction, and compressor burns out, the situation that cold-producing medium leaks.
Summary of the invention
The technical problem that the utility model will solve is, to the deficiency that above-mentioned prior art exists, provides a kind of heat-transfer fluid medium that can effectively alleviate that pipeline directly washed away the evaporimeter of pipeline long service life.
The technical solution of the utility model is: a kind of evaporimeter; Comprise the housing that is used to transmit the heat-transfer fluid medium, be arranged on heat-transfer fluid medium input pipe and efferent duct on the housing; And be contained in the some pipelines that are used to transmit cold-producing medium in the housing; Its technical characterstic is, described input pipe and housing junction also are provided with guiding device, and it comprises the guide ring that is arranged on the input pipe; Described guide ring is that an end is connected with the inwall of input pipe, and the other end outwards smoothly extends in the housing and the circular arc guide ring that forms.
After adopting above structure; Compared with prior art; The utlity model has following advantage: when the heat-transfer fluid medium reaches in the evaporimeter by input pipe, toward disperseing, medium is divided into several strands from one all around by the guide ring guiding; Effectively alleviate the heat-transfer fluid medium to directly the washing away of pipeline, prolonged the service life of pipeline.
As preferably, the internal diameter of the end that described guide ring is connected with input pipe and input pipe internal diameter equate.This setting makes the heat-transfer fluid medium smoothly smooth and easy through the process that input pipe and guiding device get into evaporimeter.
As improvement, described guiding device also comprises the annulus on the inwall that is fixed on input pipe, annulus and guide ring smooth connection.This setting is fixed on the annulus of input pipe inwall through setting, with guide ring and annulus smooth connection, make that flowing of heat-transfer fluid medium is more steady, and guide ring is more firm at the input pipe mouth of pipe.

Shown in the figure: 1, housing, 2, input pipe, 3, efferent duct, 4, pipeline, 51, guide ring, 52, annulus.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done explanation in further detail.
Fig. 1 is the broken section structural representation of overlooking of the prior art; As shown in Figure 1; A kind of evaporimeter; Comprise the housing 1 that is used to transmit the heat-transfer fluid medium, be arranged on heat-transfer fluid medium input pipe 2 and efferent duct 3 on the housing 1, and be contained in the some pipelines 4 that are used to transmit cold-producing medium in the housing 1.Fig. 2 be the utility model overlook the broken section structural representation; Its technical characterstic is; Described input pipe 2 also is provided with guiding device with housing 1 junction; It comprises the guide ring 51 that is arranged on the input pipe 2, and described guide ring 51 is that an end is connected with the inwall of input pipe 2, and the other end outwards smoothly extends in the housing 1 and the circular arc guide ring that forms.
In this example, the internal diameter of the end that is connected with input pipe 2 of described guide ring 51 and input pipe 2 internal diameters equate.
As shown in Figure 3, described guiding device also comprises the annulus 52 on the inwall that is fixed on input pipe 2, annulus 52 and guide ring 51 smooth connections.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation.The various variations of being done in the protection domain of every the utility model independent claims are all in the utility model protection domain.
