Abstract
The invention relates to a spliced aluminum alloy fin calandria evaporator which comprises a plurality of parallelly arranged aluminum alloy fin tubes, elbows, guide screws, partition tubes and holding nuts, wherein every two adjacent aluminum alloy fin tubes and one elbow are connected to form a U-shaped parallel unit, the two aluminum alloy fin tubes of each parallel unit respectively serve as a liquid inlet tube and a liquid outlet tube; the calandria evaporator provided by the invention is also provided with a liquid distributor; and the liquid distributor is provided with a liquid inlet and liquid outlets the quantity of which is same as that of the liquid inlet tubes, the liquid inlet tube of each parallel unit is communicated with a refrigerating fluid inlet tube through the liquid distributor, and the liquid outlet tube of each parallel unit is communicated with a refrigerating fluid outlet tube. The spliced aluminum alloy fin calandria evaporator provided by the invention has the advantages of adopting a parallel connection method to realize more uniform refrigeration, avoiding the problem that the temperature of a refrigerating fluid is increased along with the increment of the length of the passed distance, meeting the requirement of a large cold storage, ensuring the temperature in the large cold storage to be uniform, adopting the aluminum alloy fin tubes, ensuring good heat exchange effect, and ensuring uniformly frosting on fins.
Description
Technical field
The present invention relates to heat exchanger and thermal conduction study technical field, especially a kind of and connect formula aluminum alloy fin cooling grid.
Background technology
The calandria evaporator that uses in the existing refrigeration system mainly is formed by connecting by finned tube and bend pipe, uses seamless steel pipe or copper pipe mostly, the scene bends, welding, supporting, this mode site operation cycle length, welding, cleaning are suppressed the check trouble, difficult quality guarantee.The easy corrosion of steel pipe, the system failure is many, copper pipe cost height.Existing calandria evaporator adopts the series connection form, when being used in large cold storage, because of pipeline length longer, the temperature of the cold-producing medium in the finned tube heats up bigger with the distance lengthening of process, cause the temperature of finned tube inner refrigerant inconsistent, the heat exchange effect is reduced, and refrigeration is undesirable, causes the non-uniform temperature in the large cold storage.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve deficiency of the prior art, the invention provides a kind of and connect formula aluminum alloy fin cooling grid, adopt type of attachment in parallel to be applicable to large cold storage, it is more even to freeze, and effect is better.
The technical solution adopted for the present invention to solve the technical problems is: a kind of and connect formula aluminum alloy fin cooling grid, comprise a plurality of aluminum alloy fin pipes of arranging side by side, bend pipe, leading screw, pipe and locknut, the aluminum alloy fin pipe is provided with installing hole, leading screw is located in the installing hole of aluminum alloy fin pipe, wear the pipe that is used to keep spacing on the leading screw between the adjacent aluminum alloy fin pipe, the leading screw two ends are fixed by locknut, two adjacent aluminum alloy fin Guan Yuyi bend pipes connect to form the unit in parallel of " U " shape, two aluminum alloy fin pipes of each unit in parallel are respectively feed tube and drain pipe, also has a liquid distributor, described liquid distributor have an inlet and with the corresponding liquid outlet of feed tube quantity, the feed tube of described each unit in parallel is communicated with by liquid distributor with cold-producing medium feed liquor pipeline, the drain pipe of each unit in parallel and cold-producing medium fluid pipeline connection.
Adopt liquid distributor to make every road feed flow even, on the fin frosting even, described liquid distributor comprises a cylindrical portion and a frustum portion, offers inlet on the cylindrical portion, opens in the frustum portion and evenly is provided with the liquid outlet that communicates with inlet.
For satisfying the demand of large cold storage, the length of described aluminum alloy fin pipe is 8～20 meters.
The invention has the beneficial effects as follows, of the present invention and connect formula aluminum alloy fin cooling grid and adopt the mode be connected in parallel to realize that refrigeration is more even, frosting is even on the fin, the temperature of having avoided cold-producing medium is with the distance lengthening of the process bigger problem that heats up, satisfy the demand of large cold storage, make the temperature uniformity in the large cold storage, adopt the aluminum alloy fin pipe, the heat exchange better effects if.
