Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe it is clear that described embodiment is only a part of embodiment of the present utility model, rather than all Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, broadly falls into the scope of this utility model protection.

If it is to be appreciated that relate in this utility model embodiment directivity instruction (such as upper and lower, left and right, front, Afterwards ...), then directionality instruction be only used for explain relative between each part under a certain particular pose (as shown in drawings) Position relationship, motion conditions etc., if this particular pose changes, directionality instruction also correspondingly changes therewith.

If in addition, relating to the description of " first ", " second " etc. in this utility model embodiment, this " first ", " the Two " description etc. is only used for describing purpose, and it is not intended that instruction or imply its relative importance or implicit indicate indication The quantity of the technical characteristic showing.Thus, define " first ", the feature of " second " can be expressed or implicitly include at least one Individual this feature.In addition, the technical scheme between each embodiment can be combined with each other, but must be with ordinary skill Based on personnel are capable of, will be understood that this technical side when the combination appearance of technical scheme is conflicting or cannot realize The combination of case does not exist, also not within the protection domain that this utility model requires.

The utility model proposes a kind of refrigeration plant, it is hot enough that this refrigeration plant passes through setting microchannel offer at central sill Amount, solves the condensation problem at central sill.

In this utility model embodiment, as shown in figure 1, this refrigeration plant includes central sill 10, central sill 10 has one and houses Groove 12；Anti-condensation pipe 20, anti-condensation pipe 20 is placed in storage tank 12, and anti-condensation pipe 20 has refrigerant inlet 23 and refrigerant exit 24, there are between refrigerant inlet 23 and refrigerant exit 24 some microchannels 21 being arranged in parallel.

Specifically, the coolant loop of whole refrigeration plant includes condenser 70, throttling arrangement 60, vaporizer 50, compressor 30, also include being arranged on the anti-condensation pipe at central sill 10, these devices are connected by refrigerant pipe 40, and coolant is from compressor 30 Flow out, flow through anti-condensation pipe 20, vaporizer 50, throttling arrangement 60, condenser 70, finally flow back into compressor 30 again.And central sill At 10, its temperature of cold draining phenomenon due to refrigeration plant is relatively low, and the temperature of coolant herein is higher than this central sill 10 temperature, so Coolant outwards distributes heat and heats for central sill 10.Microchannel 21 is a kind of very small pipeline of pipe diameter, has good dissipating Hot property, compared with conventional refrigerant pipe, under same volume flow, the radiating effect of microchannel 21 is better than conventional coolant Pipeline.Conventional refrigerant pipe at central sill 10 is replaced into behind some microchannels 21, under identical cold medium flux and at a temperature of, Microchannel 21 can give out more heats, that is, have higher heat exchanger effectiveness.Can be enough to provide for central sill 10 Heat, thus improves the temperature of central sill 10 it is ensured that central sill 10 would not be because of itself temperature with the side of the contact of outside air Spend low and make the steam coagulation of in the air on this side, and then improve the experience of refrigeration plant, it is to avoid to refrigeration Equipment causes corrosion and other adverse effect.

Further, as shown in Fig. 2 microchannel 21 is arranged side by side at grade.By microchannel 21 is arranged on The surface area of microchannel 21 system on same plane, can be maximized, that is, increase heat exchange area, improve heat exchange efficiency, make Anti-condensation pipe 20 can give out enough heats.

Further, as shown in Fig. 2 two adjacent microchannels 21 are close to arrange.Space at central sill 10 is less, by making It is close between microchannel 21 arrange, just can arrange more microchannels 21 in limited space, strengthen heat exchange efficiency.And it is micro- The tube wall 22 of passage 21 connection is equivalent to rib, enhances the intensity of microchannel 21 entirety, avoids the need in central sill 10 Interior setting individually increases the object of central sill 10 and microchannel 21 intensity, and in prior art design, as shown in figure 3, at central sill Also set up a support member 80 to strengthen anti-condensation pipe 20 and central sill 10.In the present embodiment, optimize the design at central sill 10, increase Big space availability ratio, further increases heat exchange area, and make that it radiates more uniform.

Further, as shown in Fig. 2 surface within towards described refrigeration plant for the central sill 10 is the back side and described micro- logical The back side just to described central sill 10 for the road 21 place plane.Central sill 10 is mainly with the back side relative to front with contacting external air, It is easiest on its front form condensation, by the back side just to central sill 10 for the plane making microchannel 10 be located, thus can more have Effect improves the temperature in central sill 10 front, strengthens the anti-condensation effect of microchannel 21.

Further, as shown in Fig. 2 the U-shaped setting in microchannel, refrigerant inlet and described refrigerant exit are located at respectively in U The free end of two straight lengths of microchannel of type setting.U-shaped by being arranged to microchannel 21, coolant can be increased at central sill Flowing time, enable microchannel 21 to give out more heats, further increase anti-condensation effect.

Preferably, as shown in Fig. 2 anti-condensation Gutron crosses the buckle being arranged on central sill is connected with central sill.New in this practicality In the embodiment of type, this storage tank 12 is opened at the lower surface of central sill 10, and cell wall is arranged the card being adapted with microchannel 21 Button 11, during installation, microchannel 21 system is fixed in central sill 10, improves installation effectiveness.

Further, as shown in figure 1, refrigerant inlet 23 is directly connected with compressor 30.Arranged by such, compressor 30 coolant out are directly entered anti-condensation pipe 20 by refrigerant inlet 23, then out enter condenser from refrigerant exit 24 again 70, subsequently flow through throttling arrangement 60, vaporizer 70 successively, finally flow back into compressor 30.Design with respect to prior art, such as Shown in Fig. 3, in prior art design, it is provided with condenser 70 between compressor 30 and anti-condensation pipe 20, and in the present embodiment, It is not provided with condenser 70 between compressor 10 and anti-condensation pipe 20, thus can relatively improve coolant and reach anti-condensation pipe Temperature when 20, so also just improves radiating efficiency and the heat dissipation capacity of microchannel 21, further enhances the centering of anti-condensation pipe 20 The anti-condensation effect of beam 10, also optimizes the closed circuit design of coolant system.

Preferably, refrigeration plant is refrigerator-freezer or refrigerator.

The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, Every equivalent structure change under inventive concept of the present utility model, made using this utility model description and accompanying drawing content Change, or directly/be indirectly used in other related technical fields and be included in scope of patent protection of the present utility model.
