1. INTRODUCTION

ISRO Satellite Centre (ISAC), Bangalore is a lead centre of Indian Space Research Organization (ISRO) for design, fabrication, assembly and testing of satellites in India. Thermal Systems Group (TSG) of ISAC/ISRO is responsible for providing a suitable thermal control system for all its satellites.

Stirling type Pulse Tube Cooler (PTC) is developed at TSG to provide 0.7W cooling at 80K. 1W at 80K cooler is in the final stage of development. This cooler is of the active type and requires input AC power for its operation. Cooler description and salient features are given in the following sections

On behalf of ISRO, ISAC invites the proposal from reputed and experienced vendors for “Fabrication, Assembly, Instrumentation and Performance Demonstration of Pulse Tube Cryocooler” as per the requirements provided in the subsequent sections of this EOI document.

2. CRYOCOOLERS The word Cryogenics is a combination of the Greek word ‘kryos’ (very cold) and ‘genes’ (to produce). Thus cryogenics deals with the production of very cold (low) temperatures from close to absolute zero to a limit generally described as 120K. Cryocoolers or cryogenic refrigerators are devices generally working on a closed cycle with helium as working fluid used to generate temperatures in the cryogenic range for the applications mentioned above. Cryocoolers in general are classified as regenerative or recuperative systems.

The most common recuperative cycles are the Joule-Thomson, Brayton and the Claude cycle, the schematics of which are shown in Fig 1.

Fig 1: Schematic of Recuperative cryocoolers

Fig 2: Schematic of Regenerative cryocoolers

The Stirling, Pulse tube and Gifford-McMahon are the commonly used regenerative cycles, the schematics of which are shown in Fig. 2.

3. SYSTEM DESCRIPTION Among the Pulse tube cryocoolers developed, they may be broadly classified as –

a) Stirling type PTC and

b) GM type PTC

c) In each category, there exist three types of configurations as shown in Fig.3.

3.1 SALIENT FEATURES OF THE PTC 3.1.1 COMPRESSOR ASSEMBLY

The primary function of this assembly is compression of the working fluid i.e. Helium, which results in generation of the pressure wave at the desired frequency. A moving coil linear motor powered by an AC signal is used to accomplish the same. It comprises of sub-assemblies viz: : Compressor main body & interconnecting tube assembly, Piston assly, Linear motor assly, lvdt assly and bottom cover assembly.

Components used in this assembly are explained with their associated critical aspects / parameters.
