Description
Technical Field
The utility model relates to a transformer equipment technical field specifically relates to a pin-type and radiating power transformer of being convenient for.
Background
A transformer is a device that changes an alternating voltage using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are as follows: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, and the like. During operation, the transformer generates copper loss and iron loss, and the two losses are finally converted into heat energy, so that an iron core and a winding of the transformer generate heat, and the temperature of the transformer is increased. The windings also generate heat by passing current.
Among the factors affecting the service life of the transformer, temperature causes insulation aging, which is one of the most significant factors affecting the service life of the transformer. The existing lead-wire transformer is mainly applied to small-sized household appliances, the main heat dissipation mode is natural convection cooling, and the transformer shell is of a smooth surface structure, so that the heat dissipation area is limited, the heat dissipation efficiency is low, and the transformer is easy to heat after being used for a long time, so that a high-efficiency power transformer convenient for heat dissipation is needed to be developed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pin-type and radiating power transformer of being convenient for have solved the low problem that generates heat easily of long-time use of traditional pin-type transformer radiating efficiency.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a pin-type and radiating power transformer of being convenient for, which comprises a housin, the casing is inside wears to be equipped with primary, the fixed incoming wire terminal that is equipped with in primary upper portion, the primary lower part is equipped with secondary, secondary one side is equipped with terminal outgoing lines, a plurality of spiral fin of casing circumference surface mounting equipartition, be equipped with the arch between the adjacent spiral fin clearance of casing circumference surface.
Furthermore, the spiral radiating fin is provided with a plurality of circular air holes in a penetrating way.
Further, the shape of the protrusion can be a circular truncated cone, a hemisphere or a cylinder.
The technical effects of the utility model:
compared with the prior art, the lead-type power transformer convenient for heat dissipation has the advantages that the plurality of spiral radiating fins and the plurality of the protrusions are arranged on the circumferential outer surface of the shell, so that the heat transfer area is greatly increased compared with the existing lead-type transformer shell light surface structure, and the spiral structure is favorable for the ascending circulation of hot air; the heat dissipation area is further increased by arranging the plurality of circular air holes on the spiral heat dissipation sheet, and meanwhile, the pressure difference is caused by high-temperature air and low-temperature air on two sides of the air holes, so that the heat dissipation is easier.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the accompanying drawings of the present invention will be combined to clearly and completely describe the technical solutions in the embodiments of the present invention.
Example (b):
as shown in fig. 1-3, this embodiment a power transformer of lead wire formula and be convenient for heat dissipation, including casing 1, 1 is inside wears to be equipped with primary coil 2, 2 fixed incoming line terminals 4 that are equipped with in upper portion of primary coil, 2 lower parts of primary coil are equipped with secondary coil 3, 3 one side of secondary coil is equipped with leading-out terminal 5, 1 a plurality of spiral cooling fins 6 of the fixed equipartition of circumference surface of casing, be equipped with arch 7 between the adjacent spiral cooling fin 6 clearance of 1 circumference surface of casing.
The spiral radiating fins 6 arranged on the outer surface of the shell 1 have a larger radiating area relative to a smooth surface, and meanwhile, the spiral structure plays a role in guiding flow and is beneficial to rising of hot air. The plurality of protrusions 7 arranged on the outer surface of the shell 1 further increase the heat dissipation area of the shell.
The spiral radiating fins 6 are provided with the plurality of circular air holes 8 in a penetrating mode, the circular air holes 8 further increase the radiating area of the spiral radiating fins 6, and meanwhile the temperature difference between the two sides of the air holes 8 forms a chimney effect, so that heat radiation is facilitated.
The shape of the bulge 7 can be a round table, a hemisphere or a cylinder.
The above embodiments are only specific cases of the present invention, and the protection scope of the present invention includes but is not limited to the forms and styles of the above embodiments, and any suitable changes or modifications made thereto by those skilled in the art according to the claims of the present invention should fall within the protection scope of the present invention.
