Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a one-way heat exchanger. Background Art

[0002] In some specific occasions, such as when solar energy is used as an auxiliary energy source for heating, only the heat of the solar heat carrier is allowed to transfer to the main heating heat carrier, but when the temperature of the solar heat carrier is low, the heat in the main heating heat carrier is not allowed to transfer to the solar heat carrier. Traditional heat exchangers can only meet this function through valve switching, which is less practical. Utility Model Content

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 2 , which is an embodiment of the utility model, provides a one-way heat exchanger, which includes: an evaporation heat absorber 1 and a condensation heat emitter 6;

[0024] The condensing heat radiator 6 is arranged above the evaporating heat absorber 1, and a plurality of evaporating heat exchange tube bundles 2 are fixedly arranged in the evaporating heat absorber 1. The outer side of the evaporating heat absorber 1 is also fixedly connected with an evaporating heat absorber heat carrier inlet 9 and an evaporating heat absorber heat carrier outlet 10, respectively. The evaporating heat absorber heat carrier enters into the evaporating heat exchange tube bundle 2 in the evaporating heat absorber 1 through the evaporating heat absorber heat carrier inlet 9, and heats the refrigerant in the evaporating heat absorber 1 to evaporate.

[0025] A plurality of condensing tube bundles 7 are fixedly connected in the condensing heat radiator 6, and a condensing heat radiator heat carrier inlet 11 and a condensing heat radiator heat carrier outlet 12 are fixedly connected to the outside of the condensing heat radiator 6, respectively. The condensing heat radiator heat carrier enters the condensing tube bundle 7 in the condensing heat radiator 6 through the condensing heat carrier inlet 11. A refrigerant steam pipe 5 is fixedly connected between the evaporating heat absorber 1 and the condensing heat radiator 6. A spray mechanism is also arranged in the evaporating heat absorber 1, and the spray mechanism includes a spray plate 3 fixedly arranged on the evaporating heat absorber 1 and a refrigerant liquid pipe 4 arranged above the spray plate 3. The refrigerant liquid pipe 4 passes through one side of the evaporating heat absorber 1 and is connected to the condensing heat radiator 6.

[0026] In addition, sight glasses 8 are provided on the outside of the evaporative heat absorber 1 and the evaporative heat exchange tube bundle 2, and the refrigerant liquid level of the evaporative heat absorber 1 and the condensing heat radiator 6 is observed through the sight glasses 8. Four groups of refrigerant steam pipes 5 are provided, and are symmetrically arranged on both sides of the evaporative heat absorber 1 and the condensing heat radiator 6 in pairs.

[0027] The specific heat exchange cycle process is as follows: the evaporator heat absorber heat carrier enters the evaporator heat exchange tube bundle 2 in the evaporator heat absorber 1 through the evaporator heat absorber heat carrier inlet 9, heating the refrigerant in the evaporator heat absorber 1 to evaporate. The evaporation of the refrigerant is an endothermic process. The temperature of the evaporator heat absorber heat carrier decreases after absorbing heat, and flows out from the evaporator heat absorber heat carrier outlet 10. The refrigerant after absorbing heat becomes saturated refrigerant vapor, and enters the condenser heat radiator 6 through the refrigerant vapor pipe 5. The condenser heat radiator heat carrier enters the condenser tube bundle 7 in the condenser heat radiator 6 through the condenser heat carrier inlet 11, and condenses the saturated refrigerant vapor from the refrigerant vapor pipe 5 into refrigerant liquid. Condensation is a heat release process. The temperature of the heat carrier of the condensing heat radiator increases after absorbing the heat released by the condensation of the refrigerant vapor, and flows out of the condensing heat radiator 6 from the heat carrier outlet 12 of the condensing heat radiator. The refrigerant liquid flows into the spray plate 3 through the refrigerant liquid pipe 4, and then the spray plate 3 sprays the refrigerant liquid evenly on the evaporating heat exchange tube bundle 2, absorbing the heat of the evaporating heat absorber heat carrier and turning it into refrigerant vapor, thus completing a heat exchange cycle.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
