New model aluminum alloy ceiling row pipe is a new type of refrigerating equipment developed by our scientific research personnel with the experts' guidance according to the needs of the market.The utility model solves the problems of the seamless steel tube ceiling row pipe in the domestic market,and has the unique characteristics in structure,performance and installation.It is well received by users.
Single pipe of new model aluminum alloy ceiling row pipe adopts outboard wing piece appearance combination.The surface of the main pipe is provided with three reinforced air-cooling fins which are arranged in a triangular arrangement,which increases the effective heat dissipation area and enhances the strength of the single pipe.The formed aluminum row pipes are fixed in parallel,and grouped into several equal channels.When the refrigerating system is started,the cold air will form an airflow stack effect surface in the channel and sink rapidly,which accelerates air convection.Therefore,the cooling effect is effectively increased.
1)Under the same condition:
Thermal conductivity of aluminium pipe is:210W(m²/℃),but thermal conductivity of steel pipe is:46W/(m²/℃)According to the comparison,it can be shown that the aluminum
pipe is better than the steel pipe.
2)Operating temperature of aluminum alloy:
The lower limit is-26g C,and lower limit of the GB/TB163 international
seamless steel pipe ls-20 C.At present,request for low temperature of general cold storage in ctomesticis-20C~-25C the corresponding evaporating temperature is-30C~35 C.Thus,the aluminum alloy ceiling pipe can be competent for the use of ultra low environment.
3)Easy installation:
Aluminum alloy ceiling row pipe is much lighter than seamless steel tube ceiling row pipe in overall weight which makes hoisting lighter and safer and can reduce the the building structural load.The utility model can be divided into slices and assembled,and is provided with ABS material into a base when installation.Integral assembly is very convenient.
4)Reduce consumption of cryogen:
Aluminum alloy ceiling row pipe adopts outboard wing piece structure.The row pipes and filling quantity of cryogen are less than that of the seamless steel tube ceiling row pipes the auxiliary equipment volume of the corresponding refrigerating system also reduce.Therefore,the utility model can save both cost of the cryogen and refrigerating equipment.
5)Optimize the on-site environment:
Surface of the aluminum alloy ceiling row pipe are covered with anti oxidation film.which means there's no need to do antiseptic treatment.But the seamless steel tube ceiling row pipe is easy to rust in low temperature and high humidity environment.which means needed to be do anti corrosive treatment regularly,.And during the regular defrosting process,the rotten layer and frost layer of the row pipe will drop an the product or on the ground,which is easy to pollute the product.The process is not only to spend money.but also a waste of time,even affect the company's normal production.But aluminum alloy ceiling row pipe does not exist these problems.
6)Defrosting and air tightness:
Aluminum alloy ceiling row pipes all have internal anti oxidation treatment.smooth inner wall,rapid flow velocity in pipes,good heat transfer effect,grease and dirt are not easy to be deposited.The utility model has good effect on hat fluorine defrosting or hot ammonia defrosting Test pressure of the aluminum alloy ceiling row pipe is up to 1200kpa when operating.and the strength test pressure is 2400kpa,tightness lest pressure is 1600kpa.And there are three processes respectively air pressure,water pressure,pressure maintaining.which means air tight stability is very strong.
