Capri Cables P. Ltd. Shamirpet, Hyderabad, Telangana

We are offering sintered wick structured heat pipes. In this type of heat pipe, capillary wick is made of sintered powder which adheres to the inner walls of the heat pipe. This acts to transport the fluid through capillary action.

We are offering metal mesh structured heat pipes. In this type of heat pipe, the wick is in the form of metal mesh that is inserted into the pipe and made to be in contact with the inner walls of the pipe to facilitate capillary action. This type of wick is used in the majority of the mainstream products and provides readily variable characteristics in terms of power transport and orientation sensitivity, according to the number of layers and mesh counts used.

Fans provide an additional failure point, thereby reducing the system’s reliability. Fans also increase the noise of the system, can introduce dust and contaminants, and require additional power. For any one of these reasons, a system designer may wish to exclude fans from the system and use natural convection heatsinks.Since the air passing over the fins rises upwards as it absorbs heat from fins, the heat sink has to be positioned in a way so as to align the individual fins along the vertical. Also the gap between two fins has to be larger to allow for required air flow. Such constraints have to be taken into account when considering a natural convection (or passive cooled) heat sink for use.

We are offering forced convection heat sink. The cooling in this type of heat sink is done by forcefully blowing air over the fins using a blower system. Forced convection heat sinks these are the most common types of heat sinks used in the industry today due to their large heat dissipation capacity. The heat sink can be judged by amount of heat removed in a given time period and high heat loads can be removed using forced convection (or active cooled), in which the fluid flow over the fins is assisted by a blower or other means.

We are offering metal foam structured heat pipes. In this type of heat pipe, the wick is formed from pre-manufactured metal foam that is carefully inserted into the pipe and is later fused to the inner walls. metal mesh based wick structure benefits of using metal foam based heat pipes: thin and powerful wick (≥ 300 µm) giving possibility for 2mm thick flat heat pipes higher heat load capacity dry out point (>65% increase in dry-out vs. Legacy sintered powder) uniform foam thickness (increased yield) increased thermal management efficiency and reduced hot spots large wick lateral dimensions l and u shaped wicks for special vapor chamber designs

We are offering natural convection heat sink. The most common reason to require natural convection heat sink is the elimination of fansblowers from the system. Fans provide an additional failure point, thereby reducing the system's reliability. Fans also increase the noise of the system, can introduce dust and contaminants, and require additional power. For any one of these reasons, a system designer may wish to exclude fans from the system and use natural convection heatsinks.

We are offering air to air heat transfer heat transfer takes place from one air stream to the other. these heat exchangers are suitable in electronics cooling for increasingly miniaturized components within enclosures, or for demanding applications like telecommunications or militaryaerospace where weather can be a factor. They can either be forced convective (active cooled) or natural convective (passive cooled) type of heat sink, to transfer the heat within the electronic enclosures to the outside ambient air for rejection.

We offer Plain Thermal Siphons. These thermal siphons (or thermo-siphons) do not have any special structurelining on the inner walls of the pipe. Fluid return from the condenser end to evaporator end is only by gravity assisted flow. Consequently, these thermal siphons have severe limitation on their orientation of working; that is - the evaporator end of the thermal siphon has to be below the level of condenser end for the thermal siphon to work (transfer the heat under load).

Axially grooved thermal siphons or thermo-siphons use a circle of grooves in the interior wall of the heat pipe envelope as the wick efficiently pulls condensate back to the evaporator from the cooler surfaces where working fluid had condensed.
