Description

The refrigeration plant auxiliary cooler

The utility model relates to a kind of parts of refrigeration plant, especially a kind of cooler.

During the broiling summer, with regard to small-type refrigeration appliances such as existing refrigerator-freezer, Low temp. refrigerators, when being placed on higher kitchen of operating ambient temperature or sunkissed place such as outdoor, rely on the natural heat dissipation of himself configuration or the cold-producing medium that is in the condition of high temperature (as freon) that air-cooled heat dissipation structure has been not enough to compressor high-voltage end is sent to be cooled to predetermined temperature.At this moment, the refrigeration performance of equipment will be seriously influenced, and can not freeze sometimes even fully.Simultaneously, its compressor can continuously be worked, and this not only impairs the life-span of equipment, and very easily causes device damage.Therefore, for guaranteeing this refrigeration plant energy operate as normal, be necessary to provide a kind of refrigeration plant parts that can address the above problem.

The purpose of this utility model promptly provides a kind of auxiliary cooler for the small-type refrigeration appliance use.

Refrigeration plant auxiliary cooler of the present utility model has housing and condenser pipe, on housing, have water inlet and delivery port, the inner chamber of housing constitutes the fluid passage between water inlet and the delivery port, in the fluid passage of condenser pipe body between this water inlet and delivery port, the entrance point and the port of export of condenser pipe are exposed to outside the housing.In the utility model, above-mentioned housing is tubular shell especially, described water inlet and delivery port are arranged at the tubular shell two ends respectively, and the entrance point of condenser pipe and the port of export also lay respectively at the two ends of tubular shell, and the condenser pipe body is along the long axis direction coiled coil of tubular shell.When using cooler of the present utility model, the entrance point of condenser pipe and the port of export can be joined with the compressor high-pressure outlet end and the condenser inlet end of refrigeration plant respectively, the condenser pipe that also is about to this cooler is serially connected with on the compressor high-voltage end of refrigeration plant and the conveying pipe of refrigerant section between the condenser.Like this, in the use of refrigeration plant, the cold-producing medium that compressor high-voltage end is sent will pass through the condenser pipe of this cooler earlier before arriving condenser.When refrigeration plant is worked under hot environment, the water inlet and the cold water source (as running water pipe) that unloads of this cooler can be joined, allow cooling water enter tubular shell, flow out from delivery port again.In this process, the condenser pipe outer wall in cooling water and the tubular shell contacts, and the cold-producing medium that is in the condenser pipe under the condition of high temperature is imposed auxiliary temperature-reducing, allows cold-producing medium can reduce to normal working temperature, and correspondingly guarantees that refrigeration plant can operate as normal.And refrigeration plant is when working under the non high temperature environment, and then water inlet and cooling water source that will this cooler joins, and promptly do not use this cooler that cold-producing medium is imposed auxiliary temperature-reducing.At this moment, the duty of refrigeration plant is as good as when this cooler is not set.In the utility model, the cross section of tubular shell can adopt multiple cross sectional shapes such as circle, ellipse, rectangle.In addition, be the further endothermic effect that improves cooling water to cold-producing medium, but also can in the fluid passage between water inlet and the delivery port, fixedly install the flow structure of scratching that convection cell imposes obstruction.This is scratched flow structure and can be the projection that is arranged at the fluid passage sidewall, also can be the similar structures such as flowing fin of scratching that is arranged in the fluid passage.

Because cooler of the present utility model has adopted tubular shell, and make housing all be arranged on the two ends of tubular shell into and out of the import and export end of head piece and condenser pipe, this kind version help this cooler in refrigeration plant layout and the cold of cold-producing medium unloaded.In addition, the condenser pipe body of this cooler fully contacts cooling water, thereby has further improved cooling effect along the long axis direction coiled coil of tubular shell with the condenser pipe body the process that flow to delivery port from water inlet.Therefore, this cooler have be convenient to install and use, the characteristics of good cooling results, solved the problem that refrigeration plant uses effectively in hot environment.

Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is the structural representation of refrigeration plant auxiliary cooler among the embodiment.

As shown in Figure 1, refrigeration plant auxiliary cooler in the present embodiment has housing 1 and condenser pipe, housing 1 has water inlet 3 and delivery port 4, the inner chamber of housing constitutes the fluid passage 5 between water inlet and the delivery port, in the fluid passage 5 of condenser pipe body 2 between this water inlet and delivery port, the entrance point 6 and the port of export 7 of condenser pipe are exposed to outside the housing.In the present embodiment, above-mentioned housing 1 is a tubular shell, water inlet 3 and delivery port 4 are arranged at the two ends of this tubular shell respectively, and the entrance point 6 of condenser pipe and the port of export 7 also lay respectively at the two ends of tubular shell, and condenser pipe body 2 is along the long axis direction coiled coil of tubular shell 1.

During cooler in using present embodiment, the condenser pipe of this cooler can be serially connected with on the compressor high-voltage end of refrigeration plant and the conveying pipe of refrigerant section between the condenser, promptly allow the entrance point 6 of condenser pipe and the port of export 7 join with the compressor high-pressure outlet end and the condenser inlet end of refrigeration plant respectively.In the use of refrigeration plant, the cold-producing medium that compressor high-voltage end is sent enters condenser pipe body 2 from condenser pipe entrance point 6, arrives the condenser of refrigeration plant again from the condenser pipe port of export 7.When refrigeration plant is worked under hot environment, cooling water (as running water) can be introduced the water inlet 3 of this cooler, allow cooling water enter fluid passage 5 in the tubular shell 1, flow out from delivery port 4 again.In this process, the condenser pipe body 2 in cooling water and the tubular shell 1 contacts, and the cold-producing medium that is in the condenser pipe under the condition of high temperature is imposed auxiliary temperature-reducing, guarantees that cold-producing medium can reduce to normal working temperature, allows the refrigeration plant can operate as normal.When refrigeration plant is not worked under hot environment, then need not utilize this cooler to impose auxiliary temperature-reducing.But will not unload from refrigeration plant by this cooler this moment, and just do not introduce cooling water from water inlet 3, and the existence of this cooler can't have a negative impact to the work of refrigeration plant.Therefore, as a kind of standby auxiliary temperature-reducing parts, the use of this cooler is extremely flexible.

The cross section of the tubular shell 1 in the present embodiment is circular.In addition, be to strengthen the endothermic effect of cooling water to cold-producing medium, but fixedly installed in the fluid passage between water inlet and delivery port that convection cell imposes obstruction scratch flow structure 8.Herein scratch flow structure 8 for scratching the stream fin.After cooling water enters tubular shell 1, scratch flow structure 8 and make current produce turbulent fluctuation, and the time that current are flowed in housing increases.Therefore, the setting of scratching flow structure 8 can strengthen the heat exchanger effectiveness between cooling water and the cold-producing medium, further improves cooling effect.
