Abstract
Description
- 1. Technical Field of Invention
- The present invention generally relates to a heat exchanger, particularly for thermal coupling of a glycol/water circuit and a refrigerant circuit in motor vehicles.
- 2. Description of the Prior Art
- Heat exchangers are apparatuses, or components, through which heat is indirectly transferred from a first fluid mass flux having a first temperature to a second fluid mass flux having a second temperature, lower than the first temperature. The first and second fluid mass fluxes are separated from one another and pass through the heat exchanger without mixing.
- In a motor vehicle having an internal combustion engine, heat which is generated by the combustion process of the engine is typically disposed to the environment by a cooling system within the vehicle. Under certain operational conditions it is useful to divert a portion of this heat to the interior of the vehicle to heat the passenger compartment. The use of a heat pump makes it possible to use this heat within the passenger compartment. However, because of the low temperature of the diverted heat it is necessary to transfer the heat from the glycol/water circuit of the cooling system to the refrigerant circuit of the heat pump.
- Many generic heat exchangers have been developed for this type of application. Some heat exchangers are particularly designed to handle fluid mass fluxes having high fluid pressures. Other heat exchangers developed for use of different refrigerants in cooling plants/heat pump processes have very small flow cross-sections and filling capacities. In one such heat exchanger, adapted for use with refrigerants at high pressures, the refrigerant passes through the heat exchanger in flat tubes having refrigerant channels of small diameters. Ribs extend between the flat tubes to position the flat tubes at a distance from one another. These flat tubes define an air-refrigerant heat exchanger, used as an evaporator in a cooling plant.
- Such a heat exchanger is not suitable for use with a thermal coupling used to interconnect a glycol/water cooling system circuit and a refrigerant circuit. The size of a heat exchanger of this size prevents the use of a heat exchanger of this type as an additional heat exchanger within a motor vehicle.
- Another type of heat exchanger used flat tubes that are designed to be used with refrigerant at high temperatures, such at a refrigeration circuit using carbon dioxide as the refrigerant. Heat exchangers of this type are not suitable for use with a thermal coupling used to interconnect a glycol/water cooling system circuit to a refrigerant circuit.
- It is therefore an object of this invention to provide a heat exchanger, particularly for exchanging heat between a refrigerant circuit and a glycol/water cooling system circuit, whereby the heat exchanger has a small physical size and works at high rates of transferred heat fluxes, while simultaneously meeting the safety requirement necessary to operate with high pressure refrigerants.
- The disadvantages of the prior art are overcome by providing a plate heat exchanger having a plurality of first plates with first flow channels for refrigerant and a plurality of second plates with second flow channels for glycol/water mixture. A reservoir for the first plates is integrally formed with the first plates, and a second reservoir for the second plates is mounted to an outer side of the heat exchanger, whereby the second reservoir can be arranged on the same plane with the first reservoir, or offset by 90 degrees from the first reservoir.
- According to another aspect of the present invention, the refrigerant or the glycol/water mixture flows in a plane, whereby the heat between the refrigerant and the glycol/water mixture is transferred in cross and/or parallel flow, countercurrent flow, cross countercurrent flow, or cross concurrent flow. The described heat exchanger has connections for refrigerant inflow, refrigerant outflow, glycol/water mixture inflow, and glycol/water mixture outflow, or is directly connected to another heat exchanger. That is, in particular, the environment of the heat exchanger/cooler of the glycol/water circuit.
- In yet another aspect of the present invention, the heat exchanger is designed such that safety requirements are fulfilled due to small flow cross-sections of the refrigerant channels and a small total filling volume of the heat exchanger.
- In still another aspect of the present invention, the heat exchanger has a relatively small size while providing a large heat-transferring surface.
- FIG. 1 is a perspective view of a heat exchanger made from plates;
- FIG. 2 is a top view of a plate having flow channels for refrigerant formed therein;
- FIG. 3 is a top view of a plate with flow channels for a glycol/water mixture;
- FIG. 4 is a top view of a heat exchanger of the present invention.

heat exchanger 1 has connections for refrigerant inflow, refrigerant outflow, glycol/water mixture inflow, and glycol/water mixture outflow, or alternatively is directly connected to anotherheat exchanger 1. Preferably, the heat exchanger uses a refrigerant such as carbon dioxide (R744), tetrafluoroethane (R134a), or propane (R290), however, it is to be understood, that other suitable refrigerants could be utilized without departing from the scope of the present invention. - Preferably, the first and
second plates heat exchanger 1 are made of a flat material. The first andsecond flow channels second plates - The wall thickness of the first and
second plates second plates second plates - Referring to FIG. 2, the
first plates 2 includefirst reservoirs 6 for the refrigerant. Theflow channels 3 pass through theplate 2 in a preferably meandering manner and connect thefirst reservoirs 6 within each plate. Preferably, thefirst reservoirs 6 within thefirst plates 2 are integrally formed within thefirst plates 2. Depending upon the application, the refrigerant, and geometrical conditions, thefirst reservoirs 6 can be shaped either circular, oval, elliptical, rectangular, or as an elongated hole. - The
flow channels plates first flow channels 3 of thefirst plates 2 have a hydraulic diameter of between about 0.1 millimeters and about 4 millimeters. Thesecond flow channels 5 of thesecond plates 4 have a hydraulic diameter of between about 1 millimeter and about 6 millimeters. - The hydraulic diameter is defined as the product of the cross-sectional area of the
flow channels flow channels - Referring to FIG. 3, a
second plate 4 havingflow channels 5 for the glycol/water mixture includesdistance pieces 8, andpassage openings 9 for the refrigerant to connect thefirst reservoirs 6 of two adjacentfirst plates 2 with one another.Second reservoirs 7 are mounted to either side of the plate pack, in fluid communication with thesecond flow channels 5 of thesecond plates 4. Thesecond flow channels 5 extend across thesecond plates 4 to interconnect thesecond reservoirs 7. Preferably, thesecond flow channels 5 are linear and extend across thesecond flow channels 5 at an angle to the sides of the plate pack. - Referring to FIG. 4, in an alternate embodiment, the
second reservoirs 7 of thesecond plates 4 includesseparators 10. Theseparators 10 divide thereservoirs 7 into separate chambers. Therefore, the glycol/water mixture passes through only part of thesecond flow channels 5 in thesecond plates 4 from onereservoir 7 to theopposite reservoir 7, and from theopposite reservoir 7 through the remainingsecond flow channels 5 in the samesecond plate 4, back to theoriginal reservoir 7. - Depending upon the arrangement of the first and
second flow channels separators 10 in theheat exchanger 1, any type of flow pattern, such as countercurrent flow, cross flow, parallel flow and concurrent flow can be realized partially or totally. - The foregoing discussion discloses and describes the preferred embodiments of the invention. One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims, that changes and modifications can be made to the invention without departing from the scope of the invention as defined in the following claims. The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation.
