Technical Field
The utility model relates to a plate-fin radiator core assembly structure especially relates to a plate-fin radiator that outer fin positive and negative ripples is crisscross to be distributed suitable for dig machine, loader, fork truck, generating set, compressor unit.
Background
The heat dissipation system is an important component for ensuring the normal work of the power, transmission system and hydraulic system of the engineering machinery. The heat dissipation device has the main effects that heat generated by an engine system and a hydraulic system in the working process is taken away by cold air through each radiator, the purpose of heat dissipation is achieved, the engine is guaranteed to safely and efficiently run at normal working temperature, and the service life of the engine is prolonged. With the development of modern engineering machinery and automobile engines towards higher power per liter, the power performance of the engine with the same displacement is continuously improved, and the generated heat is larger. The plate-fin radiator is widely applied due to good radiating effect and long service life. Therefore, how to improve the heat dissipation performance of the radiator and improve the structural strength is a problem to be solved.
SUMMERY OF THE UTILITY MODEL
The utility model provides a plate-fin radiator with staggered distribution of positive and negative waves of external fins, which comprises a radiating core body, wherein two sides of the radiating core body are provided with side plates, partition plate strips, a radiating coil pipe and external fins are arranged in the radiating core body, a plurality of pairs of partition plate strips are arranged between the two side plates at intervals in parallel, and a spiral radiating coil pipe is arranged between each pair of partition plate strips;
and outer fins are arranged between two adjacent pairs of partition laths, each outer fin is arranged in a continuous corrugated shape, and the positive waves and the negative waves of the two adjacent outer fins are distributed in a staggered manner in the vertical connecting line direction of the side plate 5.
Furthermore, the front surface and the back surface of each pair of partition plate strips are connected with long sealing strips so as to seal the heat dissipation coil pipe.
Furthermore, short sealing strips are arranged at two ends of the outer fins and between the partition strips, and openings communicated with the outer fins are formed in one ends, close to the outer fins, of the short sealing strips.
Further, the outer fins are saw-toothed outer fins, rectangular outer fins or straight outer fins.
The utility model discloses a core assembly form is not only simple but also reliable, adopts the positive and negative ripples of outer fin to assemble in turn and promotes heat dispersion, can promote 8% probably according to incomplete statistics heat dispersion. The assembly form can effectively reduce noise, increase structural strength and improve heat dissipation performance; meanwhile, one end of the short seal strip close to the outer fins is provided with a notch, so that when cold air is prevented from blowing to the surface, vertical rebounding is formed, the cold air flow direction of the core body is disturbed, and the improvement of the heat dissipation effect is facilitated.
