The liquid phase refrigerant of high temperature that condenses in condenser 4 and high pressure is the experience throttling expansion by capillary 5 time, thereby becomes the liquid phase refrigerant of low temperature and low pressure.By after the capillary 5, evaporimeter 6 is used to make the liquid phase refrigerant of low temperature and low pressure to flash to the gas phase refrigerant of low temperature and low pressure.Evaporimeter 6 and condenser 4 are as heat exchanger.Cause within it according to evaporimeter 6 of the present invention and condenser 4 that flowing refrigerant forms turbulent flow, thereby improved heat transfer efficiency.
With reference to Fig. 3, show according to refrigerator of the present invention.Described refrigerator comprises the body 10 of the component parts that is provided with refrigerant cycles.The inside of body 10 is limited with the storeroom 11 with the opening that is formed at its front surface.But door 20 is by using hinge can be connected on the front surface of body 10 in the pivotal rotation mode, thereby the approach that enters storeroom 11 is provided.
Compressor 3 and condenser 4 all can be arranged in the machine chamber 12, and wherein said machine chamber can be defined as in the bottom of body 10 with storeroom 11 separates.Machine chamber 12 is configured to the external communications with body 10, so that machine chamber 12 can be introduced and discharge to extraneous air.
Evaporimeter 6 can be installed in the Background Region of storeroom 11.Circulating fan 13 also can be installed in evaporimeter 6 one sides in body 10, and is suitable for making the cooling air to circulate in storeroom 11.
Adopt above-mentioned structure, when the refrigerant that circulates in refrigerant cycles condenses in condenser 4 by with machine chamber 12 in air carry out heat exchange and emit heat, and in evaporimeter 6 during evaporation by with storeroom 11 in air carry out the absorption of air heat of heat exchange in the storeroom 11.Air in the storeroom 11 is cooled into cold air by the heat exchange with evaporimeter 6.Therefore, evaporimeter 6 and condenser 4 usefulness act on the heat exchanger of refrigerator.

After the outer periphery surface around refrigerant guide pipe 30 connected a plurality of heat exchange fins 40, refrigerant guide pipe 30 was arranged structure roughly to bend repeatedly to have multisection type around bent mode more.Then, a pair of supporting member 51 and 52 can be connected to multisection type and arrange the end of structure to keep the shape of heat exchanger 4 or 6 more.
With reference to Fig. 6, be provided with in the refrigerant guide pipe 30 and be used to make the turbulent flow that forms turbulent flow along pipeline 30 flowing refrigerant to cause member 60.Preferably, turbulent flow causes the vertical layout of member 60 along refrigerant guide pipe 30, and extends through refrigerant guide pipe 30 so that refrigerant forms the turbulent flow that runs through refrigerant guide pipe 30.In one embodiment, turbulent flow initiation member 60 can be set to bend around bent mode to have the line of a plurality of longitudinally kinks 61 that are orthogonal to refrigerant guide pipe 30 substantially.
When turbulent flow initiation member 60 is arranged in the refrigerant guide pipe 30, collides along refrigerant guide pipe 30 flowing refrigerant and each kink 61 that turbulent flow causes member 60, thereby form turbulent flow and non-laminar flow.Because the refrigerant by refrigerant guide pipe 30 has irregular turbulent flow, so the inner surface flowing refrigerant of the most close refrigerant guide pipe 30 and at wall portion that the center of pipeline 30 flowing refrigerant can be crossed refrigerant guide pipe 30 heat-shift energetically.Therefore, all substantially refrigerant can carry out heat exchange energetically with the air around refrigerant guide pipe 30, thereby causes the heat transfer efficiency that improves heat exchanger 4 or 6.
Turbulent flow causes member 60 preferably to be made by the material of elastically deformable, and is suitable for having the width of the diameter that is slightly less than refrigerant guide pipe 30, so that can insert in the refrigerant guide pipe 30.

With reference to Fig. 8 to Figure 10, will illustrate that a kind of manufacturing is according to the heat exchanger 4 of refrigerator of the present invention or 6 method.As shown in Figure 8, when refrigerant guide pipe 30 has straight flattening shape, can be at first connect heat exchange fins 40 around the outer periphery surface of refrigerant guide pipe 30.Next, turbulent flow initiation member 60 inserts in the refrigerant guide pipe 30 fully in mode as shown in Figure 9.Then, as shown in Figure 10, refrigerant guide pipe 30 has multisection type and arranges structure more to be bent into around curved formula.Thereafter, supporting member 51 and 52 can be connected to the multisection type that is formed by bending refrigerant guide pipe 30 and arrange the side of structure to finish the assembling of heat exchanger 4 or 6 more.
Because it is to insert in the refrigerant guide pipe 30 before bending refrigerant guide pipe 30 that turbulent flow causes member 60, therefore turbulent flow cause member 60 in the process of bending refrigerant guide pipe 30 with 30 bendings of refrigerant guide pipe.Therefore, in one embodiment, when with when bent mode bends refrigerant guide pipe 30, turbulent flow causes member 60 and is blocked and supported thus by the kink of refrigerant guide pipe 30.Therefore, turbulent flow initiation member 60 can be fixed on the place, fixed position in refrigerant guide pipe 30.
Cause member 60 ', 60 at turbulent flow " or 60 " ' among alternative embodiment of making by deformable material, the turbulent flow that is similar to previous embodiment causes member 60, can determine that by bending refrigerant guide pipe 30 fixing turbulent flow causes member 60 ', 60 assembling heat exchanger 4 or at 6 o'clock " or 60 " ' in each turbulent flow cause member.
Therefore, the heat exchanger that is used for refrigerator 4 or 6 with turbulent flow initiation member 60 according to the present invention can be eliminated and to being used for turbulent flow be caused the demand that member 60 is fixed on the independent fixture at place, fixed position, and has improved heat transfer efficiency.Therefore, eliminate independent fixture and improve heat transfer efficiency and can reduce the cost relevant with additional turbulent flow initiation member 60.
From the above clear presenting, the invention provides a kind of heat exchanger that is used for refrigerator, wherein the refrigerant guide pipe has the turbulent member that is arranged in it.Therefore, form irregular turbulent flow along refrigerant guide pipe flowing refrigerant.
Therefore, at the heat exchanger that is used for refrigerator according to the present invention, whole refrigerant along the guiding of refrigerant guide pipe can move towards the inner surface of refrigerant guide pipe, and therefore carry out heat exchange energetically with the air that centers on the refrigerant guide pipe, improve heat transfer efficiency significantly thereby cause.
