연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A motor vehicle heat exchanger for independently heating different passenger areas comprising first and second tube/fin block units for transferring heat from coolant flowing through tubes thereof to air flowing therethrough to first and second passenger areas, respectively. Common upper and lower coolant reservoir tanks supply coolant to both tube/fin units and receive coolant returning therefrom respectively. Intake tubes extend through a common gap between the first and second tube/fin units to supply heated coolant to the lower cooling tank.

1. A heat exchanger arrangement for the independent heating of two passenger areas of a motor vehicle passenger compartment comprising: a first tube and fin block unit for transferring heat between air flowing therethrough and coolant flowing in the tubes thereof to control heating of air for one of said passenger areas, a second tube and fin block unit for transferring heat between air flowing therethrough and coolant flowing in the tubes thereof to control heating of air for the other of said passenger areas, common upper and lower coolant tanks for communicating coolant to and from both of said first and second tube and fin block units, and intake tube means for supplying heated coolant to the lower coolant tank, said intake tube means extending from the upper tank to the lower tank in a common intermediate thermal gap area formed between the first and second tube and fin block units, said intake tube means extending through the fins of said units without contacting said fins so that conductive heat transfer from the intake tube means to the fins of said first and second tube and fin block units is generally avoided. 2. An arrangement according to claim 1, wherein said upper coolant tank includes partitioning walls separating an inlet area opening into the intake tube means and respective outlet areas at the upper side of the two tube and fin block units. 3. An arrangement according to claim 2, wherein said lower coolant tank is separted into respective tank compartments for the two tube and fin block units. 4. An arrangement according to claim 3, wherein the fins of the tube and fin block units extend into the common intermediate thermal gap and include through openings for the intake tube means said openings having a greater diameter than said intake tube means so there is an air gap clearance between said fins and the intake tube means. 5. An arrangement according to claim 3, wherein the common intermediate thermal gap is a gap between partitioning walls which are provided at the edges of the fins facing each other of both tube and fin block units. 6. An arrangement according to claim 5, wherein the partitioning walls are composed of shingle-like, overlapping shaped edges of adjacent fins of the tube and fin block units. 7. An arrangement according to claim 1, wherein the common intermediate thermal gap is covered by a cover element at the side facing the air flow through the two tube and fin block units. 8. An arrangement according to claim 5, wherein the common intermediate thermal gap is covered by a cover element at the side facing the air flow through the two tube and fin block units. 9. An arrangement according to claim 7, wherein the cover element is arranged at the side of the gap which is exposed to the air flow and is attached to at least one of the intake tube means. 10. An arrangement according to claim 9, wherein the cover element consists of a plate with a height extending over tube and fin block units and exhibits protruding latches attachable to the intake tube means. 11. An arrangement according to claim 10, wherein the latches are composed of an elastic material and contain recesses opened at one side, which are slid onto the intake tube means to be fixedly attached thereto. 12. An arrangement according to claim 3, wherein the intake tube means are tubes of the same diameter as the tubes of the respective tube and fin block units. 13. An arrangement according to claim 3, wherein the intake tube means are tubes of a greater diameter than the tubes of the respective tube and fin block units. 14. An arrangement according to claim 13, wherein only two of the tubes of the intake tube means are provided and they are of the same diameter and are arranged one behind each other in the direction of air flow in the common intermediate thermal gap area, whereby a partitioning wall in the lower tank extends laterally to the gap between the two tubes of the intake tube means. 15. An arrangement according to claim 14, wherein the thermal gap is delimited by partitioning walls which themselves are composed of shingle-like edges, overlapping sloped edges of adjacent fins of the tube and fin block units. 16. An arrangement according to claim 13, wherein a cover element is provided at the side of the gap thermal exposed to the air flow which cover is attached by means of protruding latches to the tubes of the intake tube means. 17. An arrangement according to claim 15, wherein a cover element is provided at the side of the thermal gap exposed to the air flow which cover is attached by means of protruding latches to the tubes of the intake tube means. 18. A heat exchanger arrangement for the independent heating of two passenger areas of a motor vehicle passenger compartment comprising: a first tube and fin block unit for transferring heat between air flowing therethrough and coolant flowing in the tubes thereof to control heating of air for one of said passenger areas, a second tube and fin block unit for transferring heat between air flowing therethrough and coolant flowing in the tubes thereof to control heating of air for the other of said passenger areas, common upper and lower coolant tanks for communicating coolant to and from both of said first and second tube and fin block units, and intake tube means for supplying heated coolant to the lower coolant tank, said intake tube means extending from the upper tank to the lower tank in an intermediate thermal gap area formed between the first and second tube and fin block units, said intake tube means extending through the fins of said units without contacting said fins, wherein the fins of the tube and fin block units extend into the common intermediate thermal gap and include through openings for the intake tubes, said openings having a greater diameter than said intake tube means so there is an air gap claarance between said fins and the intake tube means. 19. A heat exchanger arrangement for the independent heating of two passenger areas of a motor vehicle passenger compartment comprising: a first tube and fin block unit for transferring heat between air flowing therethrough and coolant flowing in the tubes thereof to control heating of air for one of said passenger areas, a second tube and fin block unit for transferring heat between air flowing therethrough and coolant flowing in the tubes thereof to control heating of air for the other of said passenger areas, the first and second tube and fin block units being fixed in spaced-apart relation to define an intermediate thermal gap area therebetween so that conductive heat transfer from one tube and fin block unit to another tube and fin block unit is avoided, common upper and lower coolant tanks for communicating coolant to and from both of said first and second tube and fin block units, and intake tube means for supplying heated coolant to the lower coolant tank, said intake tube means extending from the upper tank to the lower tank in the intermediate thermal gap area formed between the first and second tube and fin block units, said intake tube means extending through the fins of said units without contacting said fins.
