Description

Heat exchanger

The present invention relates to a kind of heat exchanger, it has a housing, be provided with a primary side and one therein and be in the primary side of conducting heat and being connected with this primary side, wherein this primary side has an elementary flow circuits that is arranged between an inlet attack and the outlet connection, and is provided with a valve and is used to control fluid stream by this elementary flow circuits.

This heat exchanger has for example been obtained open by DE 197 02 897 C2.

The best use that combines with heating system of described heat exchanger.The flow of hot water that is provided by heating system is crossed the primary side of this heat exchanger.The primary side of heat exchanger is provided with water for industrial use joint and water for industrial use input system.When drawing water for industrial use, open the valve that is connected with primary side, thereby flow of hot water can flow through this primary side.Heat just is delivered to primary side from primary side in heat exchanger then, thus the heat industrial water.In many cases, also use the valve that is connected with primary side, so that regulate the temperature of primary side water for industrial use.Under the situation of primary side wilderness demand water for industrial use, must correspondingly import a large amount of heats and correspondingly import a large amount of hot fluids that adds in primary side.

When heat exchanger and be not used in the heat industrial water, but when being used for the heating water of heating building heat supply circulation, similarly design is same is suitable for.

Importantly when less house, the house for example singly lived were connected in the heating network, people want to keep as far as possible little with being used to satisfy the necessary cost of house heat demand.But up to the present heat exchanger requires bigger locational space, and it must be connected with partly more loaded down with trivial details circuit in addition.

Task of the present invention is to construct a kind of heat exchange equipment compactly.

This task is so solving aspect the heat exchanger of the described type of beginning, and method is that valve constitution is become cartridge valve, and is placed in the housing to the part of major general's valve body.

By means of this organization plan, valve has been transferred in the heat exchanger, and before valve is arranged in heat exchanger as the member that separates before this.Can realize compact outward appearance thus.Comprise that the heating equipment of heat exchanger or the structure of water for industrial use firing equipment also obtain simplifying thus.Cancelled at least one pipe-line system between the housing of valve and heat exchanger.This heat exchanger not only keeps compactly thus.It also can be saved material ground and construct, and carries out industry simply and install.

Described valve preferably has one and the interactional valve parts of valve seat, and these valve parts can be through valve seat by through-flow.The advantage that the valve parts flow through valve seat is that the vibration trend of valve parts is compared with obviously littler under the situation of opposite through-flow direction.When in the housing that valve is arranged in heat exchanger, that is to say that to have bigger resonance body here available.By through-flow, this bigger resonance body also just no longer works by means of valve parts process valve seat, because vibration can diminish or even avoid fully.Since around bigger quality, even avoided noise formation.

Described valve preferred arrangements wherein is provided with an operating mechanism at housing with the opposed side of this inlet attack in the zone of the inlet attack of elementary flow circuits.Just from this valve of a side inflow, and valve is handled from an opposed side.This is a kind of simple relatively organization plan in design, can realize favourable movement-oriented in primary side by means of this organization plan.

In a kind of organization plan of scheme as an alternative, valve can be arranged in the zone of outlet connection, and the valve parts have a case spring, an operating mechanism reacts on this case spring.Also can make valve parts process valve seat by through-flow, even valve is arranged in the zone of outlet connection by means of this organization plan.In outlet connection, the fluid that flows through the primary side of heat exchanger has lower temperature, thereby the thermic load of valve is lower.

Preferably operating mechanism is arranged in housing at this with the opposed side of outlet connection on.The explanation of doing in conjunction with inlet attack on this is fit to equally.The circuit that leaves outlet connection can not be subjected to the obstruction or the interference of operating mechanism.

Preferably valve is arranged in the perforation, this perforation has constituted the prolongation of inlet attack or outlet connection.This has simplified manufacturing.Original perforation or the corresponding opening of just must being provided with, described perforation or opening have constituted inlet attack and outlet connection.In the viewpoint of manufacturing technology, this is fairly simple, is about to the described perforation that has the diameter of variation in case of necessity and continues, to be provided for the spatial accommodation of valve.

Preferably valve is connected with a branch sleeve, wherein this branch sleeve and this valve are from opposite side is packed housing into.Branch sleeve has constituted a kind of scheme that connects input channel or discharge line.A kind of such joint can not be subjected to the obstruction of valve.Because valve and branch sleeve interconnect, they interfix in housing.This has simplified branch sleeve and valve fixing on the housing of heat exchanger.

Preferably branch sleeve and valve body are tightened in together with screw element mutually at this.When being rotatably connected sleeve (perhaps opposite) when wanting fixed valve body equally, being threaded also can constitute in the enclosure interior of heat exchanger.Be threaded and can bear enough pulling force, thereby needn't be concerned about pressure limit in heat exchanger inside, pressure limit is provided with by valve and branch sleeve are fixed on the housing.

Preferably with branch sleeve and/or valve body and housing bonding or soldering.Soldering is more preferably.This measure is favourable for the sealing of valve or branch sleeve.For these two elements are fixed in the housing reliably, no longer require bonding or soldering.Scheme also can be used interference fit as an alternative.

Also in conjunction with the accompanying drawings the present invention is described in more detail by means of preferred embodiment below.Accompanying drawing illustrates:
