Technical Field
The utility model relates to a line bank structure especially relates to a radiating integration multi-sheet formula line bank structure of reinforcing belongs to low-voltage apparatus technical field.
Background
When carrying current, low-voltage circuit breakers and other electrical products generate heat due to their own impedance. This results in a higher temperature rise of the product, which results in a waste of energy and a structural damage. Reducing the temperature rise of a circuit breaker is an important aspect of circuit breaker design.
The circuit breaker inlet and outlet wire connecting bar is made of copper, so that the circuit breaker inlet and outlet wire connecting bar has very good heat-conducting property. Most of the heat is thus conducted out of the circuit breaker through the in-out wiring block. Through the heat dispersion of strengthening the terminal block, can have very important positive effect to the temperature rise of circuit breaker.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve exist not enough among the prior art, provide a this structure and reduce contact resistance through adopting fin reinforcing heat dissipation, integrated design, the temperature rise of row of working a telephone switchboard has been reduced to a plurality of measures such as multi-chip structure increase area of contact to reduce the radiating integrated multi-chip type row of working a telephone switchboard structure of reinforcing of having reduced the temperature rise of circuit breaker or low-voltage apparatus product.
The above technical problem of the present invention can be solved by the following technical solutions:
an integrated multi-piece wiring board structure with enhanced heat dissipation comprises a drawer base, wherein a bottom plate installed in an embedded mode is arranged in the drawer base, and conductive loop structures are embedded in the upper end and the lower end of the bottom plate respectively;
the conductive loop structure comprises three outlet row groups which are distributed at intervals, and the outlet row groups are connected with the busbar seat;
the outgoing line bank group is connected with an external copper bar, and the external copper bar extends outwards.
Preferably, the outlet row group is formed by vertically distributing 3 outlet rows at intervals, and the upper part and the lower part of the outlet row group are respectively provided with a vertically distributed radiating fin.
Preferably, the outlet row group is formed by vertically distributing 2 outlet rows at left and right intervals, and the two sides of the outlet row group are respectively provided with vertically distributed radiating fins.
Preferably, the radiating fins are fixed with the busbar seat.
The wiring bar consists of a bus bar seat, a wiring bar and a radiating fin. The wiring bar and the busbar seat adopt an integrated design, and contact resistance between the wiring bar and the busbar seat is eliminated. The wiring bar adopts a multi-piece structure, and the contact area between the wiring bar and an external copper bar is increased, so that the resistance is reduced, and the heat dissipation effect is improved. The heat dissipation fin is installed at the naked hourglass part of female row seat and terminal row for the reinforcing heat dissipation reduces the temperature rise of terminal row.
Through adopting measures such as integrated design, also reduced the size of row of connecting greatly, when the reinforcing heat dissipation, can not increase the overall dimension of circuit breaker and drawer seat.
The connection bank can be designed as a horizontal connection or as a vertical connection. The wiring row is installed in the circuit breaker drawer seat, is connected with the circuit breaker body through the bridge type contact. Can also be directly installed on other low-voltage electrical appliance products.
The radiating fin is installed at female arranging and the naked hourglass part of line bank of connecting, can strengthen female heat exchange capacity who arranges with the air, has reinforcing radiating effect, reduces the temperature rise of line bank and circuit breaker. The heat sink can be made of aluminum or copper material. The radiating fin can be arranged on the bus bar seat, and the heat conducting paste is added between the radiating fin and the bus bar seat. The heat dissipation stabs can also be directly processed on the busbar seat, and the heat dissipation effect is better after the heat dissipation stabs and the busbar seat are integrally designed.
The radiating fin structure is a vertical structure, which is beneficial to forming a heat channel and enhancing the radiating effect. Through to 4000A shelve frame circuit breaker drawer seat temperature rise contrast verification analysis, the fin structure can reduce the connection row temperature rise by 5K.
The wiring bar and the busbar seat are integrally designed, and the wiring bar and the busbar seat can be welded into an integral structure through direct forming of the copper bar or a welding mode. The contact resistance between the wiring bar and the busbar seat can be reduced through the integrated design, and the heat productivity is reduced. Meanwhile, the integrated design is also beneficial to the heat conduction performance between the wiring bar and the busbar seat, and the heat inside the circuit breaker can be better transferred to the wiring bar part.
The wiring bar can be designed into a structure with two, three or more pieces according to the number of the external copper bars. The number of the wiring bus bars is the number of the external copper bars minus one. Through the design of multi-piece formula structure, compare with traditional mode of connection, greatly increased the area of contact of terminal strip and external female arranging, reduced contact resistance also be favorable to the heat to derive simultaneously.
The utility model provides a have radiating integrated multi-chip formula wiring row structure of reinforcing under the condition that does not increase overall dimension, greatly reduced the temperature rise of drawer seat and circuit breaker.
