Description
Technical field
The present invention relates to showcase manufacturing technology field, more particularly, to a kind of showcase with back condenser.
Background technology
In prior art, the condenser of the showcase with cold preservation and freezing function typically has two kinds of mounting means: a kind of is that condenser is arranged in the compressor bin of showcase, uses cooling fan forced heat radiation；Another kind is that condenser is mounted on the back shroud of showcase, allows its natural heat dissipation in atmosphere.
The mounting means of both the above condenser has sizable drawback: wherein the first mounting means has sufficiently large space in needing compressor bin, condenser and cooling fan could be installed, it is only applicable to the showcase that volume is bigger, the showcase relatively small for volume cannot apply this mounting means, has bigger application limitation.Small volume due to table-type show cabinet, if the assembling mode of vertical show case routinely, condenser is arranged in compressor bin, use fan forced heat radiation again, architectural limitation, the space of compressor bin is limited certainly, if forcing condenser to be positioned in the compressor bin of bottom of cabinet bulk, it will increase a lot of costs.
The second mounting means is owing to being by condenser natural heat dissipation, and radiating efficiency is low.Due to the restriction of radiating efficiency, the area of condenser typically can be bigger.For desk-top refrigerated display case, owing to casing internal-external temperature difference is big, system heat load is very big, if using natural heat dissipation, due to table-type show cabinet small volume, the area of condenser is inadequate.According to the result of experimental test, owing to heat dissipation capacity is inadequate, the delivery temperature of refrigeration system can be more than 110 DEG C, and condenser temperature reaches 65 ~ 70 DEG C, leverage refrigerating efficiency and the reliability of refrigeration system.And the barriers such as wall easily encountered by condenser, both having reduced radiating efficiency, and easily produced condenser again and damage, and back temperature is the highest, user can directly contact, and has scald user that unexpected risk occurs.
Particularly refrigerated display case, is different from common refrigerator display case, owing to temperature is low and door body is glass door, causes thermic load very big, can not meet the needs of system by the mode of traditional back condenser natural heat dissipation.And owing to being limited by physical dimension, in compressor bin, or not is not provided that the placement space of the device such as condenser and cooling fan.
Summary of the invention
It is contemplated that solve above-mentioned technical problem the most to a certain extent.
It is an object of the invention to provide one need not condenser and cooling fan be arranged in compressor bin, effectively reduce the physical dimension of compressor bin, there is the wider suitability, improve the showcase with back condenser of radiating efficiency simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of showcase with back condenser, including cabinet, compressor bin, condenser and cooling fan, described cabinet includes back and cover plate, described condenser and cooling fan are all located on back and are covered by cover plate, described cover plate is provided with the first air inlet and the first air outlet, described cooling fan is provided with the second air inlet and the second air outlet, described second air inlet is located at the first air inlet, and described condenser is located at the second air outlet；Air is entered the second air inlet by the first air inlet, is then flowed to condenser by the second air outlet, is finally flowed out by the first air outlet, forms radiating airflow.
