Abstract

The utility model discloses a heat exchanger for a cold and hot water air conditioning blower with hot and cold water as hot and cold sources. The utility model has a paralleled structure with the cold and the hot sources provided with double inlet tubes and double outlet tubes, three inlet tubes and three outlet tubes, or multi-inlet tubes and multi-outlet tubes, and the structure is formed by that the metal tubes of the heat exchangers used by an original wall hanging type air conditioner, an original seat type air conditioner, or a cabinet type air conditioner is rearranged and reconnected. Original air conditioners adopting freon as the refrigerant can utilize cold and hot water as the cold and the hot sources, the underground water is especially suitable for being used as the cold source. The utility model has the advantages of energy saving, no environmental pollution, and favorable heat dissipating effect compared with the heat exchanger of an ordinary air-conditioner.

Description

Heat exchanger for cold-hot water air conditioning air feeder

The utility model relates to a kind of with the air heat exchanger technical field of hot and cold water as Cooling and Heat Source.

The heat exchanger that existing wall-hanging air conditioner, seat formula air-conditioner, cabinet air conditioner are adopted, because cold-producing medium adopts fluorine Lyons, therefore coolant channel adopts the tubule footpath copper pipe string rib structure of φ 6-φ 10mm, be connected in series (accompanying drawing I) with U type pipe (3) between each copper pipe (1), this tubule footpath copper pipe polyphone access node structure is according to fluorine Lyons and compressor characteristics design.If utilize hot and cold water as the heat exchanger of Cooling and Heat Source by existing wall-hanging air conditioner, seat formula air-conditioner and cabinet air conditioner, because the serial connection caliber is thin, will make the water inlet (4) and delivery port (5) temperature difference of heat exchanger big, the refrigerating capacity of the latter half of heat exchanger has only half of first half, poor refrigerating efficiency.

The purpose of this utility model provides a kind of air-conditioning blower heat exchanger that can make existing various room air conditioners application hot and cold water as Cooling and Heat Source.

The purpose of this utility model realizes in the following manner, former wall-hanging air conditioner, seat formula air-conditioner, the metal tube of the heat exchanger of cabinet air conditioner rearranges and connects, constitute that Cooling and Heat Source is two-tube to be advanced, two-tubely go out or three pipes advance three pipes and go out, and multitube advances the parallel-connection structure that multitube goes out, two rows, three arrange or arrange more the head of parallel transistor, one of terminal welding is advanced, discharge area is not less than the tee pipe coupling that needs to connect caliber in parallel cross section summation, four-way union or multiple way union, forming water inlet end one advances to have more, a parallel form that outes is advanced in the water side more, under the prerequisite that does not increase the heat exchanger volume, realized improving the effect of original heat exchanger caliber sectional area, solved hot and cold water by former air conditioner heat exchanger, because of the metal tube caliber little, fluid flow is little, water inlet end and the big deficiency of the water side temperature difference.

Tee pipe coupling, four-way union or multiple way union are the die cast metal moulding, also can be that welding of metallic plate and metal tube or bonding that form or nonmetallic materials are made.During installation and heat exchanger metal tube welding or bonding.

The first-selected copper pipe of heat exchanger serises connecting tube also can be other metal material, and metal tube adopts the string fin or around the aluminium fin, improves radiating efficiency.

The utility model can be installed in various original split wall-hanging air conditioners, seat formula air-conditioner, the cabinet air conditioner, compare with existing various air conditioner heat exchangers, owing to rearranged pipe in parallel, increased tube section, making former employing fluorine Lyons is the existing air-conditioner of cold-producing medium, also can use hot and cold water to use as Cooling and Heat Source, be specially adapted to underground water as low-temperature receiver, have the saving energy, non-environmental-pollution is than advantages such as common air-conditioning device heat exchanger good heat dissipation effect.Below in conjunction with accompanying drawing the utility model is described further:

The single tube serial connection heat exchanger perspective view that the former wall-hanging air conditioner of figure I., seat formula air-conditioner, cabinet air conditioner are adopted.

Fig. 4. the heat exchanger of three comb parallel connections is installed in the structural representation in the split wall-hanging air conditioner

Fig. 5. be the heat exchanger flow graph in parallel of Fig. 4 three comb parallel connections.

Fig. 6. three combs heat exchanger in parallel is installed on the schematic diagram in the formula air-conditioner.

With reference to figure I; Original single tube is connected in series heat exchanger copper pipe (I), and fin (2) and u shaped connector (3) are formed, and cold-producing medium is discharged from import (4) to outlet (5), and the formation single tube advances single tube and goes out passage.

With reference to Fig. 2-Fig. 3; Inlet end at metal tube (1) is installed tee pipe coupling (6), water outlet end is installed tee pipe coupling (7), and flowing water (8) enters from tee pipe coupling (6), flows out from tee pipe coupling (7), the two row's metal tubes of flowing through simultaneously form the biexhaust pipe parallel port.

With reference to Fig. 4-Fig. 5; In inlet end four-way union (9) is installed, water outlet end is installed four-way union (10), and flowing water (8) enters from four-way union (9), flows out from four-way union (10), and the three row's metal tubes of flowing through simultaneously form three comb parallel ports.

With reference to Fig. 6; The another kind that is three combs heat exchanger in parallel is arranged the connection form, in inlet end four-way union (9) is installed, water outlet end is installed four-way union (10), flowing water enters from four-way union (9), flow out from four-way union (10), flow through simultaneously three row metal tubes, form three comb parallel ports.
