Abstract
The utility model relates to the aluminum copper shunt of a novel heat exchanger. It includes several straight coil pipes. The characters of it lie in: the straight coil pipe is made by the copper pipe. Both ends of the straight coil pipe are connected with the main pipe. The main pipe is made by aluminum alloy. Several short copper pipes corresponding to the straight coil pipe are connected to the main pipe by the (electric) resistance welding. The short copper pipe and the straight coil pipe are soldered together. The lower extreme of the main pipe is connected with the copper pipe joint by the (electric) resistance welding. It has the character: the thickness of the main pipe wall is 1.2 millimeters. This utility model has the advantages, such as using less copper pipes in the shunt of the heat exchanger, saving the consumption of nonferrous metals, but its external connection is still unchangeable.
Description
Technical field
The utility model relates to a kind of aluminum bronze current divider of new type heat exchanger.
Background technology
Present non-ferrous metal worsening shortages, rise in price, and the current divider that the heat exchanger in the indoor and outdoor machine of air-conditioning is used is a pure copper tube, and use amount is bigger, but owing to consider that the adapter of indoor set and outer machine is supporting and expose the requirement of strength of pipe, extension tube attached also needs to use copper pipe, if can be in indoor set part adopt aluminum pipe to reduce production costs greatly, therefore how do not influence that air conditioner indoor unit evaporator normally uses and the prerequisite of installing under be the key that reduces production costs with copper pipe less farthest.
Summary of the invention
The purpose of this utility model is to solve in the prior art air conditioner indoor unit evaporator with the big problem that causes production cost to rise of copper pipe amount, and a kind of aluminum bronze current divider of new type heat exchanger is provided.The utility model designs a kind of aluminum bronze current divider of new type heat exchanger, comprise some straight coil pipes, it is characterized in that: straight coil pipe is a copper pipe, the two ends of straight coil pipe are connected to house steward, house steward is made by aluminium alloy, house steward is last to be connected with several and the straight corresponding short copper pipe of coil pipe by electric resistance welding, and short copper pipe is connected with straight coil pipe brazing, and house steward's lower end is connected with copper pipe joint by electric resistance welding.It is characterized in that: house steward's wall thickness is 1.2 millimeters.The utility model has the advantages that and in the current divider of heat exchanger, to use copper pipe less, save the consumption of non-ferrous metal, and its external connection is still constant.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is structural representation of the present utility model (evaporimeter that is used for heat exchanger).
The specific embodiment
Embodiment: the evaporimeter that is used for heat exchanger, comprise fin battle array 1, be through some straight coil pipes 2 in the fin battle array, it is characterized in that: straight coil pipe is a copper pipe, a house steward 3 of joining with straight coil pipe is respectively arranged on the both sides of fin battle array, house steward is made by aluminium alloy, house steward is last to be connected with several and the straight corresponding short copper pipe 4 of coil pipe by electric resistance welding, and short copper pipe is connected with straight coil pipe brazing, and house steward's lower end is connected with copper pipe joint 5 by electric resistance welding.It is characterized in that: house steward's wall thickness is 1.2 millimeters.
Owing to will use two house stewards in the evaporimeter in the indoor set, its caliber is thicker, if therefore it can be changed into aluminium-alloy pipe, then can save the consumption of non-ferrous metal copper greatly, thereby reduce production costs, but evaporimeter also needs to be connected with off-premises station at last, and the extension tube attached supporting with it still is made of copper, therefore consider the connection needs of extension tube attached, lower end house steward is connected with a copper pipe joint with electric resistance welding, and the straight coil pipe in the fin battle array is considered and fin battle array being connected and installed when producing, still usefulness is thin copper pipe, therefore house steward goes up with electric resistance welding and is connected with several and the straight corresponding short copper pipe of coil pipe, in the production installation process, adopt brazing to connect, so just can guarantee that evaporimeter still keeps original state when producing and install, just when the processing house steward, on house steward, be connected with several and straight corresponding short copper pipe and the copper pipe joint of coil pipe with electric resistance welding in advance, and the production cost that is spent with electric resistance welding connection short copper pipe and copper pipe joint is very cheap, is significantly smaller than the expense of the copper of saving.
And the current divider in the radiator in corresponding and the heat exchanger also adopts aluminum bronze current divider of the present utility model with the foregoing description similarly.
Claims (2)
1. the aluminum bronze current divider of a new type heat exchanger, comprise some straight coil pipes, it is characterized in that: straight coil pipe is a copper pipe, the two ends of straight coil pipe are connected to house steward, house steward is made by aluminium alloy, house steward is last to be connected with several and the straight corresponding short copper pipe of coil pipe by electric resistance welding, and short copper pipe is connected with straight coil pipe brazing, and house steward's lower end is connected with copper pipe joint by electric resistance welding.
2. by the aluminum bronze current divider of the described a kind of new type heat exchanger of claim 1, it is characterized in that: house steward's wall thickness is 1.2 millimeters.
