The device disclosed by the invention is smaller in engineering quantity, shorter in working period and lower in cost, and the structure and the use of an existing constant-temperature and constant-humidity box are not affected.
Description
Technical field
The present invention relates to automobile heatproof detection technique field, refer to a kind of multi-direction local temperature control of resistance to thermal exposure pick-up unit especially; Be mainly used in auto parts and components and other have the experiment of strict heat resistant requirements to product, when the environment temperature required and product surface temperature inconsistent time, the temperature of carrying out local controls.
Background technology
Carrying out in heatproof testing process to heat-resisting stricter product, in time product heat-resisting being only required to environment temperature (such as: environment temperature 80 DEG C), we can be placed on product in climatic chamber and carry out heating.
In prior art means, in climatic chamber, add a firing equipment heat product surface, but it can cause environment temperature to raise, climatic chamber can reduce the temperature of environment accordingly, but common firing equipment cannot adjust temperature dynamically.
But, when the heat-resisting environment temperature of product requires and the temperature requirement of product surface is inconsistent (such as environment temperature require 80 DEG C and product surface temperature requirement 100 time), if be just placed in climatic chamber, cannot control the temperature of product surface.Especially also need, in conjunction with moisture-proof, the parameter such as cold-resistant, heat-resisting, to carry out moisture-proof thermocycling experiment etc., it require our temperature to refer to timing point and period control.Simple climatic chamber can only specify time point and period to control environment temperature, but cannot control for product surface.Cause properties of product to be tested the most at last cannot meet the demands, cannot realize carrying out at appointment time point and period the subject matter that control temperature becomes the solution of the invention needs.
For the heat-resistant experiment of auto parts and components product etc., when product surface temperature requirement is higher than environment temperature, the local irradiation device just needing some special controls to the temperature realizing local location.Such as: for automotive upholstery A, for the requirement of its moisture-proof thermocycling experiment, require first it to be put at room temperature 1 hour according to real vehicle confined state, lower 5 hours of the environment temperature of 80 DEG C, then puts at room temperature 2 hours, then 3 hours are at low temperatures put, then put at room temperature 2 hours, be then placed on moist environment lower 7 hours, then put at room temperature 2 hours, whole circulation gets off to take 1 day (24 hours), altogether will do 4 circulations.All these require that we directly can be realized by climatic chamber.But add owing to also having one and require it is while environment temperature is 80 DEG C, the surface temperature of tested exemplar A needs to reach 110 DEG C.This is required that existing climatic chamber just cannot be corresponding.
Somebody is by loading onto infrared lamp at the top of common climatic chamber, by the thermocouple connecting product surface, temperature signal is passed to control system, control system adjusts according to the exposure intensity of difference to top IR lamp of observed temperature and design temperature, quantities is large, long in time limit, cost is high, and between processing period, climatic chamber is occupied, other experiments cannot be implemented, cause the larger waste of resource.
