Description

Radiator

Technical Field

The utility model relates to the technical field of heat dissipation devices, in particular to a heat radiator.

Background

High-power equipment can generate more heat in the operation process, and part of equipment with requirements on the working temperature is required to be additionally provided with a radiator, and the radiator is generally directly integrated on the shell of the equipment. The existing radiator mostly adopts the following three heat dissipation modes: firstly, forced air cooling, namely direct blowing and cooling by a fan; secondly, natural air cooling, namely, the equipment shell is additionally provided with radiating fins, so that the radiating area is increased; and thirdly, a combined heat radiation mode of the fan and the heat radiation fin. In addition, water-cooling radiator has appeared in the market, through external cooling circulation system, can improve the radiating efficiency of equipment by a wide margin. The air cooling heat dissipation is relatively lower in cost, but the heat dissipation effect is not as good as that of the water cooling heat dissipation, the efficiency of the water cooling heat dissipation is high, but the cost is higher because the water cooling heat dissipation is matched with a corresponding cooling circulation system, and the water cooling heat dissipation have advantages and disadvantages. In the conventional radiator, only one radiating mode is usually selected, if the radiating mode is to be changed (for example, the equipment is modified, the equipment power is increased to cause insufficient radiating, or the equipment power is reduced, the running requirement can be met without high-efficiency radiating), the radiator is generally required to be replaced entirely, and the shell of the equipment is also required to be replaced at least partially, so that the change is troublesome.
