This heat must be removed to prevent damage to heat critical components. Heat removal may be by natural disszpation, air

31、cooling, or where these measures water system. This section concerns the centralized cooling water system, as specified in are not adequat to remove the required amount of heat, by a centralized electronic cooling MIL-W-21695, composed of the necessary pumps, heat exchangers, demineralizers, water f

32、low controls, pressure relief valves, temperature regulating valves, temperature, flow and pres- sure indicators, conductivity i.ndicators, alarms, air trap and expansion tank, stop valves, piping and all other accessories required to insure a continuous flow of cooling water of specified characteri

33、stics to the electronic equipment. Cooling of water f0r.th.e electronic cooling water system is via heat exchangers using water from the sea water system or the ahilled water system. 5.2 Interface characteristics. The interface characteristics of the ships cooling water system are described in 5.2.1

34、1 through 5.2.4. Each shipboard system will deliver cool- ing water with these characteristics to the electronic equipment interface. Distilled water, 0.065 equivalents per million (epm) chlorides maximum, wil-1 normally be used for filling of electronic cooling water .systems. 5.2.1 Purite. The pur

35、ity characteristics will be as“fol1ows: I (a) Conductivity: Not in excess of 2.0 microsiemens per centimeter (vs/cm) (micromhos per.centimeter) corrected to 25OC (77OF). (b) Oxygen concentration: 0.5 parts per million (p/m) by weight maximum. (c) Filtration: Size of solids will not exceed 0.5 microm

36、eters. Full flow filtration will be-provided if required by the electronic equipment. 5.2.2 Temperature. The temperature of the cooling water provided to the electronic equipment inlet connections will be not greater than 4OoC (105OF) on surface ships, and not greater than 35OC (95OF) on submarines.

37、 .The cooling water system can easily provide.water at higher temperatures if required in special cases, and when operating in cold sea water, lesser temperatures may be available. The ability of electronic equipment to use water at a .temperature not greater than 4OoC (105OF) on surface ships and 3

38、5OC (95OF) on submarines is extremely critical because of the added cost involved in supporting any requirement less than these temperatures. Such requirement will involve the use of chilled water from the air conditioning system in lieu of the use of sea water for the heat exchanger. This will 2 Pr

The intcrfacc characteristics of the shipboard clectronic cooling watcr system impose certain constraints on the design of electronic equipment utilizing such support. Thcsc constraints are spccikd in 5.3.1 and through 5.3.5. 5.3.1 Compatibility. Thc dcsign

44、 of clcctronic equipment utilizing ships cooling walcr support shall bc compatible with the interface characteristics given in 5.2. 5.3.2 FRSSM drop. The maximum pressure drop from inlet to outlet of each clectronic cabinet shall not exceed G9 kPa (10 Ib/in%). However, state-of-the-art breakthrough

45、is required in certain tube designs (e.g., klystron tubc) in order to stay within the maximum G9 kPa (10 Ib/in2) pressure drop. While a high pressurc piping system required to support large pressure drops is not desirable from the point of view of the additional weight and cost involved, when weighe

46、d against the probability and cost of the state-of-the-art breakthrough in tube design, it may be a cost- crfective compromise and a deviation from this interface constraint may be indicated. In such instance, the need to deviate from this pressure drop interface shall be fully justified (sce 7.1).

47、5.3.3 External connections. Each unit shall have a single supply and single return watcr connection for attachment to the electronic cooling water system. The two connections, lor rigidly- mounted equipments, shall be union joints or flanges in accordance with Category C-1 of MIL- STD-777 for surfac

48、e ships or Category N of MIL-STD-438 for submarine service and shall bc rigidly fastened to the outside surface of the enclosure.
