In particular, the present invention relates to an enhanced non-suffocating warming system for automobile cabin, which can extract heat in an improved way from the car cooling or exhaust system, moreover and it utilizes this heat to provide comfort conditions inside the vehicle cabin using one or more heat dissipating floor mat(s).

BACKGROUND OF THE INVENTION

[0002] Most of vehicles are fitted with a cabin heating system to provide comfort conditions inside the passenger compartment specially in winters. The passenger compartment mostly equipped with a compartment heater which is designed to extract heat from the engine and then blown warm air into the passenger compartment. As soon as engine gets enough warm, the heated coolant is transferred into the heater core which is located inside the dashboard of passenger compartment. The cold air impelled by an impeller and blown over the heater core, in this way cold air become warm and further supplied to the vehicle cabin via air vents.

[0003] Most of such heating systems or similar heating systems having capabilities to increase the cabin temperature of a vehicle very rapidly at desired level but such type of heating can cause some side effects on the occupants like irritation, headache, suffocation, vomiting and some other discomfort issues. These problems may arise due to the rapid change in cabin temperature or blow of hot air on the passengers' face and head area. Such type of heating is not good for health and may cause mentioned problems.

[0004] Such type of heating system can increase the cabin temperature very rapidly and can create irritation to the passengers sitting inside the cabin. Therefore, those systems are essentially required, which are capable to heat cabin area very smoothly so that suffocation and irritations can be prevented. In addition, the blowing hot air is not good for passengers because it may cause headache and other discomfort issues.

[0005] So, for heating a vehicle's cabin space specially in winters, such types of heating systems are essentially required, which may free from all the mentioned health issues on the driver as well as passengers sitting inside the vehicle.

[0006] The US Patent No. 1,148,617 discloses a motor car heater, this invention relates to a car heating system, more particularly invention employing a heater of the combined radiator and register type which are particularly adapted for the determination of using the exhaust from engines of motor vehicles for the heating purpose of the cars.

[0038] A four-wheeler should essentially have an internal combustion engine along with liquid cooling or exhaust system to employ the enhanced non-suffocating warming system for automobile cabin (100). A bypass unit (200b) can be advantageously fitted with both and/or either cooling or exhaust system of the vehicle. The bypass unit (200b) further coupled with an evaporating unit (200a), hot fluid (exhaust gas/hot coolant) enters from the bypass inlet hose (9) and then discharged via a discharge hose (11) to the evaporating unit (200). During the functioning of enhanced non-suffocating warming system (100), both throttle valves (5) &

(6) remains fully opened, while bypass throttle valve (14) of bypass hose (13) remains partially closed. The evaporating unit (200) of the invention further comprising an evaporating unit casing (1) which is hollow and cylindrical in shape, and optimally rectangular casing can also use for evaporating unit casing. The evaporating unit casing (1) having plurality evaporator shell(s) (2) equidistantly positioned inside the evaporating unit casing (1), each shell (2) having an opening (3) outside the evaporating unit casing (1). The opening(s) (3) are basically a threaded connector(s) through which a primary heating fluid (26) can be filled inside each evaporator shell (2). During the functioning of enhanced non suffocating warming system (100), all the evaporating shell(s) (2) remains surrounded by the hot fluid (exhaust gas/ hot coolant) and the heat of hot fluid further supplied to the plurality evaporator shell(s) (2). Due to the heat transfer from hot fluid to the evaporator shell(s), heat conducted through the evaporator shell(s) material and then transferred to the primary heating fluid (26) filled inside the plurality evaporator shell(s). The hot fluid (exhaust gas/ hot coolant) after commissioning its role further exit via a second bypass exit hose (12) connected with the throttle body (8) of evaporating unit (200a) and finally escaped via the bypass unit outlet pipe (10) and/or first bypass exit hose (10).

[0039] A condenser unit (300), which is further comprises of a condenser unit casing (17), which is circular in shape and optionally shaped, can be modified to rectangular shaped casing. The condenser unit casing (17) can be covered with an insulating material, so that; heat loss from the condenser unit casing (17) to atmosphere can be prevented. Plurality condensing shell(s) (18) are equidistantly fitted inside the condenser unit casing (17) and each condensing shell(s) (18) having an opening (19) outside the condenser unit casing (17). The opening(s) (19) are threaded connectors, through which primary heating fluid (26) enters into the condensing shell(s) (18) in boiling or super-heated vapor state. The condenser unit casing (17) filled with a secondary heating fluid (44) which remains surrounded to each condensing shell (18). A secondary heating fluid reservoir (22) coupled along with condenser casing (17) perpendicularly to the axis of condenser casing. The level of the secondary heating fluid reservoir (22) is higher the level of the casing (17). The secondary heating fluid reservoir (22) maintains the required level of secondary heating fluid inside the condenser casing (17). Each shell opening (19) of condensing shell (18) can be further connected with the respective shell opening (3) of evaporating shell (2) using an insulated hose (16) having identical leakproof nut(s) (4) fitted at the both ends of each insulated hose (16). Leakproof nut(s) (14) can be easily tightened on the opening(s) (3) & (19) to form a leakproof connection of evaporating unit (200a) with condenser unit (300).

[0040] Each evaporating shell (2), condensing shell (18) and insulated hose (16) remains filled with a primary heating fluid (26) in such a way that condensing shell(s) (18) remains partially empty while the plurality insulated hose (16) and plurality of evaporating shell (2) remains fully filled. Empty volume inside each condensing shell (18) has been provided for the occupancy of superheated vapors of primary heating fluid (26).

[0041] The level of condenser unit (300) kept above the level of evaporating unit (200a). Due to the convection currents, the hot currents of primary heating fluid (26) from the evaporating shell(s) (2) rises via the insulated hose(s) (16) into the condensing shell(s) (18), while the cold currents of primary heating fluid (26) flows down to the evaporator shell(s) (2) and optionally only temperature exchange through the primary heating fluid can be allowed.

[0042] A secondary heating fluid (44) surrounds each condensing shell (18) in the condenser unit (300) in the present invention. Due to the temperature of primary heating fluid (26) and its vapors, condensing shell(s) (18) became hot and this heat further transferred to the secondary heating fluid (44). The secondary heating fluid provides cooling to the condensing shell(s), but in this process; secondary heating fluid also became hot and/or temperature of secondary heating fluid increase. The condenser unit (300) fitted with a condenser inlet port (20) and a condenser exit port (21), through the condenser inlet port (20) cold secondary heating fluid enters inside the condenser unit casing (17) and hot secondary heating fluid (44) from the condenser casing (17) exit via a condenser exit port (21).

The hot secondary heating fluid (44) coming from the distributor unit (30) further circulated inside the heat dissipating mat (400) through plurality U-turn channels. When hot secondary heating fluid (44) flows inside the heat dissipating mat (400), secondary heating fluid (44) transfers its heat to heat dissipating plate (42) through which heat radiates inside the vehicle cabin. During this process secondary heating fluid (44) drops its temperature and attenuated temperature secondary heating fluid (44) further exit via at least one exit port either (36) or (37)/ or which one is in use.

[0045] The cold secondary heating fluid from heat dissipating mat (400) enters into the receiver unit (33) via an insulated hose (32).
