30-3-2003 ORGN Form 2 The patents act, 1970 (39 of 1970) Complete Specification (See Section 10) HEAT EXCHANGER APPLICANT OJAS PANDYA NO.l SHRI HARI APARTMENT, KARELIBAUG, VADODARA, GUJARAT, INDIA.390018. TEL : (R/O) +91 (0265) 2491390 GRANTED The following specification (particularly) describes the nature of the invention and the manner in which it is to be performed. PROPERTY HEAT EXCHANGER : New type of heat - exchanger is made with pipes having rectangle cross-sectional area. This near-exchanger is finsiess, there are not fins. This new type of heat exchanger is made in various designs, which are illustrated by different figures 1 to 8. There is fins-less pipe having rectangle cross sectional area is common in all designs of new type pf heat exchanger. First design of new type heat exchanger is illustrated in figure 1, pipe-having rectangle cross sectional area is inlayed with cubic tank around tank there is one inlet and one outlet to pass refrigerant thought this pipes. Second design of new type of heat-exchanger is illustrated in figure 2, pipe having rectangle cross sectional area is studded with cylinder tank around tank there is one inlet and one outlet to pass refrigerant through this pips. Third design of new type of heat-exchanger is illustrated in figure 3, there is finless pipe having rectangle cross sectional area there is inlet and outlet to pass refrigerant through this pipe. Fourth design of new type of heat-exchanger is illustrated in figure 4, there is finless pipe having rectangle cross sectional area there is inlet and outlet to pass refrigerant through this pipe. Fifth design of new type of heat-exchanger is illustrated in figure 5, there is finless pipe having rectangle cross sectional area there is inlet and outlet to pass refrigerant through this pipe. Sixth design of new type of heat-exchanger is illustrated in figure 6 pipe having rectangle cross sectional area inlaying in a cell there is inlet and outlet to pass refrigerant and any material through these pipe and cell has inlet and outlet to pass any material and refrigerant through this ceil. Seventh design of new type of heat-exchanger is illustrated in figure 7, there are pipes having rectangle cross sectional area inlaying in a cell these pipes have inlet and outlet to pass refrigerant through these pipes this cell has water tank, spray nozzles to spray water on pipes, eliminator air blower to blow air on pipes. Eighth design of new type of heat-exchanger is illustrated in figure 8 this is cell having same gap at all over which is heat-exchanger there is inlet and outlet to pass refrigerant through this cell. This new type of heat exchanger is made with super conductor metal of heat like copper, Aluminum brass, steel, gunmetal etc. Primary refrigerant and secondary refrigerants used in new type of heat exchanger. Primary refrigerants: - Uses :- New type of heat exchanger is used as evaporator, Condenser, oil cooler, chiller, heat-exchanger etc. in unites like refrigerator, deep freezer, milk cooler, water-coolers, window air-conditioner, central air conditioner plant, chiller plant, ice plant, dairy plant, split air-conditioner, package air-conditioner, radiator In automobile, cold storage plant, making cold medicine bottle-cooler, cooling unit in every field like domestic, all factories, dairy, theater, hall, commercial automobile etc. Advantages: New type of hear - exchanger is finsless and with pipes having rectangle cross sectional area and old type of heat -exchanger has fins and pipes having round cross sectional area so new type of heat exchanger is two and half more efficient than old type of heat - exchanger because there is maximum inner volume and minimum outer area in pipe having round cross sectional area and there is minimum inner volume and maximum outer area in pipe having rectangle cross sectional area. In field of automobile heat - exchanger is used as a radiator has pipes having rectangle cross sectional area with fins dust cause chocking up gap of fins and hinder air flow and reduce efficiency of radiator. This new type of heat - exchanger has finsless pipes having rectangle cross sectional area so there is no problem of chocking up with dust to new type of heat. - exchanger and no problem of hindering air flow and reducing, efficiency of heat-exchanger and there is no requirement of periodical servicing. I Claim, 1. A heat exchanger comprising, a compressor, condenser, expansion valve and evaporator, characterised in that the heat exchange tubes or pipes are rectangular in cross section and do not have fins to facilitate easy maintenance and to improve the efficiency of operation, 2. A heat exchanger such as here in described with reference accompanying drawings and description, Dated this 24th Feb of 2004.
