Description
Technical Field
The utility model relates to the field of refrigeration equipment, in particular to a high-efficiency low-temperature air cooler.
Background
As is known, the fresh air low-temperature air cooler is based on the principle similar to that of an air conditioner, and the difference is that the temperature of the fresh air outlet is lower; the air quantity of the full fresh air low-temperature air cooler is not too large because the air outlet temperature is required to be lower than zero, and the air outlet temperature cannot be lower than zero like the air quantity of an air conditioner. The conventional design of the existing full fresh air low-temperature air cooler is to thicken the thickness of the evaporator, increase the distance between fins, reduce wind resistance and enable wind to stay in the evaporator for a long time.
However, this design presents 4 problems:
1. because the air quantity is small, the air speed is low, the evaporator is easy to frost, the evaporator can be full of frost in about half an hour, and the fan can blow out granular ice residues or floating frost to influence the effect of air outlet humidity control and the normal operation of the evaporator;
2. because the temperature difference of the inlet air and the outlet air is relatively large, the working efficiency of the evaporator is very low;
3. the frosting speed of the evaporator is high due to the large temperature difference, so that the frosting can be performed only in a flat mode in order to keep the heat exchange efficiency of the evaporator, the fan cannot continuously perform low-temperature air supply for a long time, and the refrigerating effect is affected;
4. the frosting speed of the low-temperature blower blade on the output blade impeller due to the frosting is very high, the blade frosts in 1 hour, and the abnormal sound of the dynamic balance difference of the blade due to the frosting can be heard in 2 hours, so that the damage rate of the blower is very high, and the maintenance cost is increased.
Disclosure of Invention
The utility model aims to provide a high-efficiency low-temperature air cooler, which improves the circulating air speed around an evaporator by adding an internal circulating fan and an internal circulating air duct, improves the heat exchange efficiency of the evaporator, slows down the frosting time of the evaporator, prolongs the defrosting period, ensures that low-temperature cold air blown out by a fresh air low-temperature air cooler is more continuous and durable, can effectively prevent the output of floating frost and ice slag at a low-temperature air outlet by adopting the design of a double fan, and is beneficial to popularization and use.
The utility model aims to achieve the aim, and the aim is achieved by the following technical scheme:
the utility model provides a high-efficient low temperature air-cooler, includes the air-mixing chamber, be equipped with the refrigeration evaporimeter in the air-mixing chamber, air-mixing chamber one side is equipped with the fresh air inlet, air-mixing chamber one side that keeps away from the fresh air inlet is equipped with the air outlet, be equipped with the forced draught blower in the air outlet, still communicate there is the inner loop wind channel on the air-mixing chamber.
Further, two ends of the internal circulation air duct are respectively communicated with two sides of the air mixing chamber, one end of the internal circulation air duct is at the same side as the fresh air suction inlet, and the other end of the internal circulation air duct is at the same side as the air outlet.
Further, an inner circulating fan is arranged at one end of the inner circulating air duct, which is on the same side as the air outlet.
Compared with the prior art, the utility model has the beneficial effects that:
this patent increases the circulation wind speed around inner loop fan and inner loop wind channel come the improvement evaporimeter on original full new trend low temperature air-cooler's basis, has promoted evaporimeter heat exchange efficiency, has slowed down the evaporimeter frosting time, and is long defrosting cycle in the time of being long, makes the low temperature cold wind that new trend low temperature air-cooler blows out more continuous lasting, and inner loop fan, certain than the forced draught blower, the air supply volume is big with the volume of induced drafting, because of the inner loop fan amount of wind is big, the frost that floats on the evaporimeter must be absorbed by inner loop fan, the forced draught blower just does not have frost and ice sediment output this moment, the output of low temperature air outlet ice sediment just can effectively be prevented to the design of two fans also, be favorable to using widely.
