Description
Technical field
The present invention relates to battery pack and parts thereof, especially the cooling device of battery pack.The invention still further relates to a kind of liquid-cooled power brick.
Background technology
Electrokinetic cell refers generally to have the battery of higher capacity and certain output power density, and the driving power and the hybrid power power supply class battery that can be used as means of transportations such as motor vehicle use.The part electrokinetic cell also can be used as energy storage battery usually through design improvement, comprises the variable load accumulated cell apparatus of electrical network.Also can be used as the stand-by power supply of operating office etc. in addition.Power battery pack generally is made up of plural electrokinetic cell monomer.
In recent years, lithium rechargeable battery has represented the rosy prospect as the electrokinetic cell in future.But because the structure and the principle of lithium rechargeable battery, lithium rechargeable battery in use often produces big heat because of internal resistance, particularly when heavy-current discharge, the heat that produces is bigger, if therefore can not fundamentally solve the heat management problems of lithium rechargeable battery, to there be potential safety hazard, and influence the useful life of battery, and directly influence it and apply.
In the lithium rechargeable battery heat management, allow lithium rechargeable battery fast cooling and guarantee that the homogeneity of battery temperature is a main target.
The battery pack of Americanized pure electric vehicle TESLA has adopted the coolant feed pipe to lower the temperature to the lithium rechargeable battery of column type, but its coolant feed pipe is not directly to contact with battery, but conducts heat by the resin and the battery surface of heat conduction.The capacity of heat transmission of heat-conducting resin is limited, and good especially heat-conducting resin costs an arm and a leg, so the cooling system efficient of the battery pack of TESLA is not high enough, and in order to reach the battery cooling, its system's power consumption is also bigger.
Summary of the invention
When cylinder type lithium ion secondary battery is used as power battery pack, be starved of the liquid-cooled-type cooling device that a kind of heat transfer area is big, conduction of velocity is fast.In addition, many cylindrical lithium ion secondary battery groups are deposited problem of ubiquity now: the firm welding degree of battery plus-negative plate and flow collection sheet is bad, comes off easily.One of them reason is that the plastic stent rigidity of battery pack is not enough, battery pack support thermal coefficient of expansion and metal flow collection sheet differ bigger in addition, after time was long, because material aging or the like causes that pad is subjected to displacement, it was all the more so particularly frequently to act on occasion in external force.
For solving the problems of the technologies described above, the invention provides a kind of cooling frame that adopts the class tube shell type structure, it comprises housing and pipe; The two ends mouth of pipe of pipe all is connected on the housing, the circular hole of existence and pipe equal diameters on the housing, and circular hole equates with the quantity of the pipe mouth of pipe, still be siphunculus with the corresponding pipe that makes in the position of the mouth of pipe; Housing and pipe constitute the cavity body structure jointly.
The common cavity body that constitutes of described housing and pipe is enclosed, still leaves cooling agent ostium and tap hole and flow out and flow out cavity body for cooling agent on housing.The external coolant circulation device of cooling agent ostium and tap hole, after inserting cylindrical battery in the pipe, thereby cooling agent just can flow in cavity and reaches effect to battery refrigeration.Cylindrical battery can be fixed by battery bracket.
The present invention also provides a kind of cooling device of battery pack, and it comprises cooling agent storage tank, pump, coolant feed pipe and the present patent application various cooling frames required for protection.
The present invention also provides a kind of liquid-cooled power brick; it comprises more than one battery module, cooling agent storage tank, pump, coolant feed pipe; wherein, each battery module comprises the present patent application cooling frame required for protection, two battery brackets and cylindrical battery.
Though it is cylindrical battery group of the present invention has also adopted the structure of class shell-and-tube, different fully with tube heat exchanger.Tube heat exchanger 100 as shown in Figure 1 (shell and tube heat exchanger) claim tubular heat exchanger again.Be to be enclosed in the wall of restraining in the housing dividing wall type heat exchanger as heat-transfer area.This heat exchanger structure is simpler, and operation is reliable, and available various structural materials (mainly being metal material) are made, and can use under high temperature, high pressure.Its structure is made up of parts such as housing 101, heating surface bank 102, tube sheet 103, deflection plate (baffle plate) 104, adapter 106 and bobbin carriages 105.Housing mostly is cylindrical shape, and tube bank is equipped with in inside, and the tube bank two ends are fixed on the tube sheet.Carry out cold and hot two kinds of fluids of heat exchange, a kind of mobile in pipe, be called tube side fluid 110; Another kind of mobile outside pipe, be called shell-side fluid 111.For improving the individual heat transfer coefficient of extratubal fluid, some baffle plates are installed in housing usually.Baffle plate can improve shell-side fluid speed, force fluid in accordance with regulations distance repeatedly laterally by the tube bank, the enhance fluid turbulent extent.Heat exchanger tube can be by equilateral triangle or square arrangement on tube sheet.Triangular arranged is compact, extratubal fluid less turbulence height, and individual heat transfer coefficient is big; Square arrangement is then managed outer the cleaning conveniently, is applicable to the fluid of easy fouling.
Tube heat exchanger is the exchange heat that is used between liquid liquid, gas-liquid or gas gas, no matter because be gas or liquid, thereby the tube wall that touches that tube side fluid and shell fluid can both be sufficient reaches desirable heat exchange effect.But tube heat exchanger never is used for the exchange heat between solid-liquid or solid and gas, also never is applied in the battery pack.Pipe in the tube heat exchanger mainly is passing through for liquid or gas, therefore gas after using bobbin carriage with heat exchange usually or liquid are collected and are concentrated, and pipe size and length are to design according to the heat exchange effect, the shape of pipe and size design according to the shape of battery in the class shell-and-tube cooling frame of the present invention, the sufficient contact that battery and pipeline are accomplished, and in shell side using gases or liquid coolant, thereby reached extraordinary refrigeration.
In addition, cylindrical battery group provided by the invention and class shell-and-tube cooling frame also comprise following advantage:
1, good cooling results.Because the pipeline of class shell-and-tube cooling frame fully contacts with the cylindrical battery sidewall, lower the temperature not only can for battery rapidly, and in each class shell-and-tube cooling frame, the direction of ANALYSIS OF COOLANT FLOW is opposite, can guarantee the homogeneity of battery temperature.
2, class shell-and-tube cooling frame also has the effect of support, firm cell and battery pack.Compare with the battery pack that supports at common plastic stent usually, because the easy deformation of plastics is aging, the solder joint of battery is loosening easily under conditions such as vibrations, and the present invention used be the class shell-and-tube cooling frame of aluminum or almag, because of thermal coefficient of expansion relative with the flow collection sheet difference less, impact resistance more.
3, modularized design.Can select the included battery module of each power brick as required, and the included class shell-and-tube cooling frame number of each battery module.
