Electronic computer facilities (ECF) are widely used for processing in control systems of ships of various classes. Almost all the energy supplied to the ECF from the ship's electrical networks is converted into heat inside the ECF and should be removed to ensure proper operation.
This article is devoted to the heat removal systems in high heat dissipation shipboard ECF. The issues of placing cooling equipment on objects are considered. An analysis of the energy characteristics is carried out, taking into account the contribution to the general characteristics of the object.

The purpose of this article is to choose a cooling system that will optimally meet the requirements for ECF and ensure its reliability during the entire operation of the system.

Cooling systems must ensure the operation of the ECF on the objects without significantly degrading the performance of the ECF and the ship. The operational characteristics of the object or the ship that must be taken into account when choosing a cooling system include the volume and mass of the ECF, the energy consumed for the cooled ECF and the ship's support systems.

The cooling systems of the shipboard ECF are complex engineering structures. They include refrigerators, pumps, fans, heat exchangers, air ducts. Therefore, the choice of the optimal type of ECF cooling system for a ship of a certain class can only be made by considering this task with the ship's design engineers.

The article considers the way of heat transfer from the EFC to water bodies. The analysis of various cooling systems was carried out: air and liquid cooled systems. This allowed the development of a methodology for evaluating the choice of cooling systems and the equipment used.

The research shows that conductive liquid cooling system better dissipates heat from the heat source than the air-cooling systems of different types. Liquid cooling systems allow to accommodate up to 17% more units. Liquid cooling systems can be designed to consume less energy from the ships power network by using existing on-board equipment for refrigerant supply.

The obtained research results are used in methodological instructions for radioelectronic equipment design.
